Chionobas.—To hear of the occurence of Chionobas Macounii in the hill-prairie district south of Calgary will doubtless be as much of a surprise to most entomologists as the discovery of it here has been to myself. That a man who, like myself, is ever on the outlook for anything fresh in the way of butterflies, should have lived for five years in Macounii locality without knowing it surpasses my comprehension. whilst overhauling, relaxing, and setting last winter from the captures of the past two seasons, I came across, amongst some papered specimens that had been handed to me by a Mr. Hudson, an ardent collector here, a papered butterfly labelled “Chionobas Chryxus, ♀, July 4th 1896,” taken amongst the spruce about twelve miles west of here; that is to say, about 26 miles to the south-west of Calgary. Now, though I have never yet seen Chryxus here, I have always been expecting to come across it amongst the spruce, and was not much surprised. However, after relaxing and setting me specimen, lo and behold! it was not Chryxus, but agreed rather closely with some C. californica♂ ♂ that I have from Ft. Klamoth, Oregon.

Dr. L. O. Howard, who is preparing a general article on the subject of insects affectin tobacco, for the Year Book of the U. S. Department of Agriculture for 1898, has called my attention to a plant louse feeding upon tobacco plants grown on the grounds of the Department, which he wishes to mention specifically in his article, and since it is a new species, at his request, I submit for pulication the following description.

I had been familiar with this undescribed species since 1897, and had found it on the grounds of the Department of Agriculture in smaller colonies on Rumex crispus, Leucanthemum vulgare, Forsythia viridissima, and also on the leaves of the apple, pear, and egg-plant. Specimens have also been received from Mt. Holly, Md., where they were reported to feed in immense numbers on the tomato plant.

When examining some stems of timothy grass taken from a wheat field in Prince Edward Island, where this year's crop had been badly infested with Hessian Fly, I found two of the stems of timothy which bore the undoubted flax-seed-like puparia of the Hessian Fly.

Pontania consors, new species.

Larva and Galls.—Dyar, Jour, N. Y. Ent. Soc., VI., June, 1898 p. 121.

Female.—Lenght, 4.5–5. mm.; slender; surface shining, not at all pubescent; clypeus distinctly emarginate, lobes triangular; ocellar basin distinctly defined, but with walls rounded; crest rather sharp, unbroken; fovea oval, distinctly defined; antennae short, joints 3 and 4 subequal; sheath moderatly broad, regularly rounded at tip; clothed with a rather dense fringe of long browish hairs; cerci narrow and elongate; claws deeply cleft, rays subequal; venation normal, upper discal cell of hind wings elongate, as long as or exceeding lower. Colour black; orbits and face brownish-yellow, including the area between the bases of the antennae; pronotum, tegulae and legs for the most part and venter of abdomen yellowish or resinous; bases of coxae black; posterior tarsi strongly infuscated; sheath dark brown; apical half of abdomen, dorsally, resinous, more or less infuscated; veins and stigma dark brown or strongly infuscated; wings hyaline or nearly so.

Family XIV. Tenthredinidae.

This family is probably the most extensive of any of the families of the sawflies, and is of world-wide distribution, representatives of it being found in all parts of the world, although, as a whole, it is more numerously represented in the Palearctic and Neotropical regions than elsewhere.

Eriococcus Tinsleyi Ckll.

Adult ♂. Length, 1.3 mm.; expanse of wings, 2.5 mm.; colour, head and abdomen purplish-gray; meso thorax light ochreus, some specimens show a wide longitudinal streak on the abdomen. Legs and antennae concolorous with body. Antennae 10-jointed. Joint 2 is bottle shaped, proximal end smallest, 70 μ long, practically identical with second joint of Phenacoccus solenopsis, Tins., except that E. Tinsleyi has a number of stout blunt spines interspersed with the bristles; joint 3 cylindrical, considerably longer than any of the others (130 μ long,) only differing from P. solenopsis in having the stout blunt spines; joint 4 often shorter than 5, but sometimes longer, 76–85 μ; joint 5, 81—87 μ long; joint 6 usually next, longer than 2, 68–78 μ long; Joint 7 shorter than 2.68 μ long; joint 10 usually next, 65 μ; next 8, 56 μ shortest 9, 50 μ. Joint 10 is flask shaped, tapering distally. All the segments bear the stout blunt spines, interspersed with rather stout bristles. Formula 3, 5, 4, 6, 2, 7, 10, 8, 9.

Eutolype grandis, n. sp.

Ground colour an even, smooth, bluish-gray, washed with smoky brown. Head with a little admixture of brownish in front. Collar with a small central brown spot. Patagiac margined with brown. Basal tuft of thorax with an admixture of black scales. Primaries with all the ordinary markings obscured, the most evident Feature being a broad light gray band at inner third outwardly margined by a brownish shade, which is the darkest part of the wing. The basal space is uniformly smoky gray to the t. a. line, which is narrow, geminate, even,a little incurved between the subcostal and submedian veins. The included space is light gray, and light gray shade extends to the rigid median shade, including the orbicular. T. p. line narrow, geminate, denticulate, widely bent over the cell, then with a deep incurve beneath, narrowing the median shade at the inner margin. The entire median space beyond the gray band has a warm brown tint in which the large reniform is obscurely visible as a dull, lead-coloured blotch, outlined by paler gray scales. Beyond the t. p. line the wing is of the same dull gray as at base, interrupted by the diffuse, somewhat irregular s. t. line. There is a dusky line at the base of the fringes, which are alternately black and white marked at their tips. Secondaries smoky brown, much paler at base, and with a darker line at the base of the fringes. Beneath, primaries smoky blackish, powdered with bluish-gray scales in the terminal space, secondaries grayish-white, powdery, with a blackish outer line and discal spot.

Sphaerococcus sylvestris, n. sp.

Much like an Eriococcus in shape. 2½ millim. long, 1½ wide, dark dirty brown, with a little white cottony down at its anal end, and on the mid-dorsal line a distinct longitudinal nearly white band. (King.)
