Since 1923 the writer has operated a light trap at Bozeman for the purpose of recording fauna and seasonal fluctuations in the population of Phalaenid moths. This trap, known as the “Field Trap,” is located on the east edge of a large agricultural experimental field which is cut into many plots. The trap is about 100 yards west of the nearest building, and is on a pole with the light about six feet above the ground.

Length 2.3-2.4 mm. ; width 1.1 mm. Elongate, suboval, moderately convex, fulvo-pubescent. Piceous with distinct aeneous lustre; each elytron with two yellow spots; the one as long as wide, including hunerus and basal margin and extending inwardly to the third interval; the other elongate oval and slightly oblique, extending from apical third to a point near apex.

The series of papers entitled “Observations on the Chermidae (Hemiptera: Homoptera)” is to be considered as closed. Mr. Fred Klyver, author of the accompanying paper, will continue the series under the general title of “Notes on the Chermidae (Hemiptera : Homoptera).” There is appended herewith a bibliography of the former series and other papers on the Chermidae by the present writer.

E. ternaria (group). Two specimens so named were captured at Three Forks Aug. 19, 1925 and Sept. 4, 1926.

1310 E. atropulverea Sm. One specimen in Smith collection taken at Butte, Aug. 28. 1900, by R. A. Cooley. One specimen from Bozeman, Aug. 27, 1929. 1310. I E. setonia McD. One specimen taken at Three Forks July 22, 1926 by C. B. Philip.

Early in 1928, at Salmon Arm, B.C., a thirty foot tree of Vine Maple (Acer circinatum Pursh.) which had been dead for three years, was found to be infested with Ceranibycid larvae. Accordingly the tree was felled, cut into two-foot sections, and portions from six inches to half an inch in diameter were put into a wire-screen cage under as natural conditions as possible, and in the shade. As it happened, this shady position seems to have been well chosen, as of seventeen infested maples examined during 1928-1929 only two occurred in the sun.

The best way to “remember” some rare butterfly or other insect type which you may examiine in a distant collection is to possess a good upper and under side photograph of it. Clearly taken pictures never deceive and they make later identification relatively simple. It costs time and money to travel around the country and inspect types in the various museums and for this reason it is well to “bring home” at the time a lasting reference, especially if the procedure of taking the pictures is easy and inexpensively worth while. Nowadays any entomological specialist of repute must know what neighboring names stand for before he can apply new ones and for this reason, and in order to write strictly modern descriptions of comparative nature, a photograph of related objects is the best mental guide to have in lieu of actual specimens.

Since the discovery of the Oriental Peach Moth in Ontario in 1925, yearly studies have been conducted to determine the extent to which our native parasitic hymenoptera have transferred their attention to this new source of host material. These studies have disclosed 15 of our native species attacking the Oriental Peach Moth, but as yet, little assistance in the form of actual control has developed from their efforts. During 1929 only 2.2 per cent. of 3298 larvae reared were parasitized by them; thus it seemed advisable to attempt the introduction of species which have proven of major importance in controlling the pest in areas of older infestation.

The Fire Brat, Thermobia domestica Packard, seems to have been in Eastern Canada for some time. Since, as its nick-name indicates, it is a heat-loving species, favouring steam-heated buildings, it has probably been established in the country for a long time although the records of its distribution in Canada are few and are all fairly recent.

The season of activity of P. pallipes begins about the last of April. My notes show that on April 24, 1920, a survey of the Wickes region discovered no wasp enterprises whatsoever; April 28 in 1921 found a few queens out on the flowers and a few just beginning their nests; the most progressive had completed three cells.

During the early summer months of 1927, 1928 and 1929, several fruit growers in the Salmon Arm district of British Columbia noticed severe injury to the small developing fruits of their pear trees. By the end of June as high as 80 per cent. of the small pears had fallen from some of the trees, and the majority of those remaining were deformed and unmarketable at harvesting time.

The fact that the petiole of the nest of P. annularis is thickened from time to time as the weight of the nest increases shows that the wasps can adapt their behavior to the needs of the day, even though their chain of work is interrupted. The first part of the nest to be made is the petiole; this is made by the queen long before the first workers emerge.

The name cow grasshopper has been chosen for this insect because of the habit of the female in selecting cattle “chips” or dung in which to place her eggs. On account of this habit, cattle have become an important factor in the spread and perpetuation of the grasshopper and to associate it with the name of its unconscious benefactor seems appropriate.

♂ ♀. Head.—The rostrum equals the fore coxa in length. The maxillary palpi are slightly more than two-thirds the length of the rostrum. The frons is broadly rounded. There is a lower general row of three stout bristles and an upper genal row of six bristles. There is no genal ctenidium. The occipital bristles are arranged in three rows. The bristles of the second antennal segment are short and fine. The club of the antenna is distinctly segmented all of the way around.

Length 7 mm.; width at the humerus 3.2 mm. Elongate, with the sides of the elytra almost parallel. Black with a slightly aeneous lustre; the lateral bead of the pronotum, the sides of the elytra and the two spots on the head, reddish; the labrum is cream; the antennae are pale with the apices of the segments beginning with the sixth, infuscate; the palpi are pale with very slightly infuscate apices; the legs and coxae are pale red with the femora darker. The under surface is black except for the posterior borders of the abdominal segments which are narrowly reddish. The pronotum is notably unicolorous except for the marginal bead.

Sometime ago while experimenting on ways and means of making butterfly wing-prints I discovered a process which I believe to be new and simpler than any yet devised. Several methods have been used in the past, notably by Denton in his butterfly and moth books. One of the chief methods and one which has been described in several places is that of coating a matt surface paper with a solution of gum arabic and pressing the butterfly or moth wing upon this surface under a screw press. After being allowed to harden the paper with the wing adhering is removed from the press and the wing stripped off leaving the scales sticking to the gum-coated surface of the paper.

In his paper on the genus Scolops (Kansas University Science Bulletin, Volume XVIII, page 417, 1928), Breakey comes to the conclusion that Scolops cockerelli Fowler is a synonym of Ball's Scolops robustus. On pages 427-428 he records the comparison of specimens of a number of closely related species with the type specimen of Fowler's species by Mr. W. E. China of the British Museum.

Late in the summer of 1926, several adults of the beetle (Microrhopala vittata Fabr.) were found in the blistered portions of leaves of the compass plant (Silphium laciniatum L.). The insect is black with head and thorax red and with red stripes on the second costa and at the outer margin of each elytron. It is subdepressed and about 6 mm. long.

During the past four or five years, several puzzling specimens of a form of Euxoa closely related to plagigera and oblongostigma have been collected in various parts of Montana. Some examples were submitted to Dr. McDunnough in the writer of 1927-8, and he reported as follows:

This form has always puzzled me; it occurs in Utah and I believe it to be a brown form of plagigera but some run very close to oblongostigma and are very hard to separate without genitalic slides.

The manner in which bees and wasps repeatedly find their way back to their nests or to certain other places has been a source of wonderment to many and the subject of serious investigations upon the part of but few. The justly illustrious Fabre in considering the homing of many insects was led to believe that wasps and bees found they way back and forth from the nest by a special sense.

The species herein described was reared from the immature stages of a sawily collected at Mont Laurier, Quebec, by Mr. M. B. Dunn. It is the fifth species belonging to the genus Spathimeigenia Townsend.
