Dryophanta rydbergiana, n. sp.—Gall: on leaf of Quercus rydbergiana, Ckll. (Torreya, Jan., 1903). solitary, 6 mm. diameter, spherical, faintly shiny, light ferruginous, with a microscopically tessellate surface and a scattered stellate pubescence; base concave, point of attachment small; contains a single large cell; the space between the cell and the exterior filled with spongy tissue, which is light green within and ferruginous outwardly.

Eucorethra, Underwood*

Intermediate between Corethrella and Sayomyia, having the antennæ 14-jointed, as in the former, but the spaces between the verticels almost bare, as in the latter; differing from each in the much shorter second joint of the antennæ, which is only slightly longer than wide. Antennæ of male rather robust, submoniliform on the basal half, the first six joints only slightly longer than wide, the remaining joints increasing in length and decreasing in diameter toward the apex, the antepenult about half as long as the penult, verticels composed on numerous very long bristly hairs except on the last joint; antennæ of female nearly cylindrical, the joints gradually increasing in length to the apex, scarcely thickened at the insertion of the verticels, which consist of a few rather short bristly hairs; probosics about one and one-half times as long as height of head, palpi inserted near three-fourths of its length, 4-jointed; first tarsal joint much longer than the second; venation as in Culex.

Among some hymenoptera recently received from Mr. A. Gordon Leavitt, of St. John, N. B., is a very interesting male of Thyreopus latipes, Smith. The sexes of this genus are readily separated, as the males have the anterior legs remarkabty modifed; the tibiæ: especially being developed in broad shields, or leaf-like expansions. The antennæ are simple in the female, but those of the male have the flagellum fusiform and compressed. In T. latipes the basal joints are broad, and the flagellum narrows from the second joint to the apex.

Anopheles Barberi, new species.—Near Walkeri, but only about half as large, the upright forked scales of the occiput chiefly yellowishwhite, body devoid of scales, etc. Black, the base of the antennæ, clypeus, stems of halteres, coxæ and trochanters yellow, thorax and scutellum yellowish-brown, front portion of the former and the pleura more yellowish, occiput devoid of appressed scales; thorax somewhat polished, thinly bluish-gray pruinose, the hairs and bristles chiefly black, those of the abdoment mostly yellowish, of the coxæ yellow; femora with a distinct bluish tinge, tarsal claws simple; wings hyaline, the scales brown, the lateral ones lanceolate, petiole of first submarginal cell about one-third as long as that cell, base of the latter much nearer the base of the wing than that of the second posterior cell, hind crossvein less than its length from the small crossvein; length, 3 mm.

Andrena thaspii, n.sp. ♀.—Length 10–11 mm.; black, clothed with light ochraceous pubesence; head broader than thorax; facial quadrangle broader than long; cheeks broad, shining, with fine punctures,which are very close immediately behind the eyes; front below ocelli distinctly striate; facial foveæ broad, containing iight pubescence; antennæ long and slender, black; flagellum brownish testaceous beneath, especially towards the tip; joint 3 of the antennæ as long as 4 and 5 together; ciypeus shining, clothed with thin, light pubescence; a distinct impunctate line in the middle, otherwise with moderately coarse punctures; basal process of labrum truncate; mandibles dull testaceous at the tips; mesothorax slightly shining, and covered with short, thin pubescence; on the scutellum the hairs are rather long and dense; the punctures of the mesonotum are shallow and not close together; wings yellowish hyaline, hardly clouded at the apex, with honey-coloured nervures and stigma; second submarginal cell slightly narrowed above, about half as long as the third, receiving the first recurrent nervure beyond the middle of the cell; metathoracic enclosure defined by an impressed line,its surface more fine1y sculptured than the surrounding area of the metathorax, except at the base, where it is slightly rugose; legs dark brown; tibial scopa bright fulvous, shining; the basal joints of the middle and hind tarsi and covered with ferruginous pubescence on their inner surface; abdomen shining, with sparse light hairs which are long on the first segment, but otherwise very short, forming thin apical fasciæ on segments 2 to 41 anal fimbria dark fulvous, inclining to ferruginous.

The knowledge of our Arctic insect fauna is of so fragmentary a character that any contribution thereto is of special interest and value to Canadian entomologists. I am indebted to Dr. Hans Kiaer, of the Museum of Tromso, Norway, for a copy of an exceedingly valuable catalogue entitled “Die Arktischen Tenthrediniden,” * an examination of which emphasizes this fact. His introduction points out that in Candad little is known of the forms occuring north of St. Martin's Falls, Lat. 51°, whereas in Norway species are recordd from as far north as Lat. 70°. Of 228 species enumerated (including 12 of Siricoidea) Arctic Scandinavia furnishes 132, Nove Zemlya 18, Spitzbergen 6, Iceland 3, Greenland 2, Hudson's Bay region 59, Alaska 8, and Arctic Siberia 11.

Dr. Hopkins gave an account of his preliminary survey, during the past summer, of the forest regions of different sections of the country to determine the primary enemies of forest trees and locate the areas of principal depredations. Between July and November he was in 27 States and two territories. His first trip was made through the South-eastern States, to determine the area of a recent outbreak of Dendroctonus frontalis. He found in the southern Appalachian region that this, one of the most destructive insects of American coniferous forests, was commencing its ravages as it did a few years previous to the great devastation wrought by it in the Virginias.

Our knowledge of the group Aphididæ in California has been limited in the past to certain forms that were of economic importance in their relations to cultivated crops. No systematic list of these interesting insects has heretofore been attempted in this region, and this has not been due to any lack of material, for the varying conditions of climate here seem to be particularly favorable to them.

Aleurodes Marlatti, n. sp.

Egg.— Size about. 1 mm. × .2 mm., exclusive of stalk, which is quite short, holding egg in upright position of leaf; regularly elliptical in outline. Colour, dirty yellowish brown, as seen on leaf; under transmitted light, yellowish. Shell without markings or sculpturing of any kind.

Larva.— Broadly elliptical. Colour, except in first stage which is yellowish, brownish to brownish black, varying in some specimens to an iridescent blue black; in later stages, margined all around with a short, rather squarely-trimmed, white waxy secretion, from the marginal wax tubes.

Culex cantator, new species.—Female. Near sylvestris, but the seventh abdominal segment almost wholly yellow scaled, etc. Head black, oral margin and base of antennæ yellow, remainder of antennæ and the proboscis black, palpi brown, its scales chiefly concolorous, no cluster of white hairs or scales at their apices; narrow scales of middle of occiput golden yellow, the upright ones chiefly black, sides of occiput covered with depressed whitish scales and with a small cluster of black ones; thorax reddish brown, scales of mesonotum golden yellow, becoming pale yellow in front of the scutellum and on teh pleura; abdomen black, its scales black, except a crossband of yellowish white ones at base of each segment, the bands considerably narrowed at the middle, similar scales scattered over the sixth and nearly the whole of the seventh segment and alng apices of the two preceding segments; legs yellow basally, becoming brown on the tibiæ and tarsi, scales of femora chiefly pale yellow, of the tibiæ mostly black, those on the hind side pale yellow, on the bases of the tarsal joints whitish, those on the second joint of the hind tarsi covering about one-fourth the length of the joint, front tarsal claws toothed; wings hyaline, lateral scales of the veins long and narrow, hind crossvein nearly its length from the small crossvein, petiole of first submarginal cell from one-half to four-fifths as long as the cell; length, 4 mm.

I have just noticed Prof. Webster's note an the tomb of Thomas Say, and it may be of interest to your readers to know that I have recently visited New Harmony, Ind., and met Mr. John Crobin, the owner of the old Maclure home, where stands the tomb of the father of American descriptive entomology. Mr. Corbin, as Prof. Webster states, is much interested in the proper preservation of this tomb, and is much interested also in the history of Thomas Say. In fact, I found many people in the little village of New Harmony who knew about Say, and who were distinctly of the opinion that his residence in their village sheds lustre on its history. The village library is an admirable one, housed in a beautiful building, and among the treasures of the library are certain of Say's manuscripts, among others, one written upon the day of his death.

Hab.—Beulah, N.M., alt. 8,000 ft., very abudant on Rudbeckia ampla, A. Nelson. It is preyed upon by Hippodamia convergens. This species is easily known by its bright scarlet colour. Monell reports N. rudbeckia from many genera of Compositæ at St. Louis, Mo.; in New Mexico I have found it only on one species of Rudbeckia; even the species on Rudbeckia hirta is quite different.

A small collection of mosquitoes has been sent me by Dr. Grabham, collected by himself and Mr. T.D.A. Cockerell at Pecos Canon, New Mexico, U.S.A.

This collection was made in June and contains five species, namely:

1. Theobaldia incidens, Thomson.

2. Culex Kelloggii, Theobald.

3. Culex consobrinus, Desvoidy.

4. Grabhamia Curriei, Coquillett.

5. Grabhamia vittata, nov. sp.

The small Coccinellidæ commonly known as Smilia are among the more important natural enemies of the Coccidæ. The name Smilia properly belongs to a well-known genus of Homoptera, so in Science Gossip, 1900 p. 606, I proposed to call the Coccinellid genus Epismilia. I now learn from the Index Zoologicus that Epismilia was used in 1859 for a genus of Coelenterates. I therefore propose another name for Smilia, Weise, namely Microweisea. The North American species are Microweisea misella (Lec.), M. marginata (Lec.), M. coccidivora (Ashm.), M. ovalis (Lec.), M. atronitens (Casey), M. minuta (Casey), M. planiceps (Casey), Mreversa (Fall); all standing in our lists under Smilia.

There are certain species here and there among our months which are possessed of a sort of will-o'-the-wisp evasiveness, and one would as soon think of encountering them in nature as of finding the mythical pot of gold at the rainbow's end. The causes that bring about such conditions are, of course, varied, and these species often stand represented by some unique type in a distant collection. That the British Museum has long taken first rank in sheltering may of these uniques goes without saying, hence the matter of a rediscover becomes of more than ordinary moment. Further, an additional satisfaction arises, if at a second meeting with the reculuse the early history is exposed as well, and we find the way open to a more extended acquaintance, the while getting an insight into the specific standing, had that ever been questioned.

The following list of Coccidæ, which have been sent to me for study, adds considerably to the known range of a large number of species, while several new food-plants are indicated; and as no records of the species herein cited have appeared, to my knowledge, other than in one or two instances in some of my published papers on the Coccidæ, it seems, therefore, that these miscellaneous results should be recorded. It will also show to some extent what is being done in a private laboratory for the advancement of science.

The eggs of this species were received from the Rev. R. W. Anderson, of Wando, North Carolina. They hatched May 22, and the larvæ were matured by the middle of July. The larvæ are coloured to resemble a piece of wood or bark, and remain all day motionless, hidden on the ground. They are remarkably sluggish, can be handled free for a considerable time without making the slightest motion. They are general feeders.

Melissodes brevicornis, Cress.—Lincoln, Aug. 12–27, on Teucrium Canadense. The ♀ differs from the ♂ only in having the face-parts black, pubescence on face lighter, segments 2 to 4 only banded; the scopa is yellowish. The ♂ ♂ taken all bad the tibiæ and tarsi entirely fulvous.

In the July number of the Canadian Entomologist, Prof. J.M. Aldrich attempted to rescue Dr. Williston's Culex inornatus, from the synonymy by referring the true Culex eonsobrinus, Desvoidy, as a synonym of Culex pipiens, Linné, and denying that any of the other species which the writer originally placed in the synonymy of consobrinus is identical with inornatus.

On the 6th May, 1901, a cluster of 30 eggs of Cricigrapha Normani, Grt., was found by the writer. Six of these had been destroyed and the contents eaten, probably by some hemiptetrous insect. The eggs were laid in rows close together, touching each other, on the upper side of a leaf of Caulophyllum thalictroides, Michx., and formed almost a completed square, an average of six eggs being in each row. They looked as if they had just been laid. Yound maple, ash and birch trees were growing near by.
