Deltocephalus Callidus, n. sp.

Form and general appearance of signatiforns nearly, more robust, venation slightly variable, resembling that of compactus. Length 3 mm.; width 1 mm.

Vertex obtusely angulate, one-sixth wider at base than its middle length, scarcely equalling the pronotum; front long and narrow, but slightly wider than clypeus below; pronotum more than twice wider than long; elytra equalling the abdomen, rather broad, outer claval area slightly reticulated, central anteapical cell usually divided.

Genitalia: female, ultimate ventral segment nearly four times wider than long, posterior margin slightly emarginate with a short broad medium tooth; male valve broad, short; plates broad at base, concavely, attenuately pointed, two and one-half times longer than valve, equalling the pygofers, which are thickly beset with stout hairs.

Described from two females and two males from Holly., Colo. The small size and the black spot near the anal angle of the elytra at once distinguish this species.

Hadenella subjuncta, Smith. A few at light in 1897 about the beginning of July. (See page 323, Vol. XXX.)

Drybota stigmata, Grt. Cartwright.

Polia confragosa, Morr. Sept. 15th (1896). Three specimens at sugar in Elm Park.

Laphygma frigiperda, S. & A. Sept. 8th, one at bloom.

Eupsephopæectes procinctus, Grt. Cartwright. I think Mr. Heath has only taken one of these fine insects.

Trigonophora periculosa, Gn. Cartwright.

Brotolomia iris, Gn. June 19th, etc., several at light, also taken resting on walls of house.

The beetles enumerated below were taken in 1897, some of them while the writer visited that city on the occasion of the annual meeting of The Royal Society of Canada, in June. Unfortunately, the weather was most unpropitious for insect hunting until the last day, when quite a number were taken, and later on in the season the list was increased by captures made by a brother, resident of the city.

While some of the species were well represented, very many were by only one or two specimens, and in a few cases by three or four. I feel very gratful to Prof. H. F. Wickham for kindly determining many of the species.

Anyone with the use of my table of families ought readily to recognize any wasp falling in this family, and especially after reading my remarks under the family Mellinidæ. The only group that could possibly cause trouble or confusion would be the subfamily Gorytinæ, which closely resembles the Mellinidæ, but which may be easily separated from the latter by paying close attention to the shape of the first abdominal segment and examining the mesoplueura for the mesosternal suture or carina.

Pterellipsis, n. gen.—Near Megistopoda, but with aborted wings. Head once and a half as high as long, in profile subhemispherical, covered with bristles which are longest on upper part of the front; eyes oval, situated on sides of head slightly behind the middle, no ocelli; antennæ one-jointed, flattened, elliptical, three-fourths as long as the head, once and a half as long as wide, covered with bristles and bearing a long one at apex. Thorax greatly compressed, strongly gibbous, the sternum flattened; its front end lamelliform and prolonged in front of the anterior coxæ, a longitudinal impressed median line and on each side, slightly behind its middle, is an impressed line extending from its obliquely outward and backward to the lateral margin just behind the middle coxæ wings narrow, projecting obliquely upward and forward, divaricate, once and one-third as long as height of thorax, four times as long as wide, with three veins besides, the costal, each of the median veins forked near the middle, the front fork of the anterior vein reaches the costa near the last fourth of its length, the posterior fork ends in the extreme tip of the wing; the forks of the following vein are united at their apices, and extended obliquely forward, reaching the wing-margin slightly below the tip; a short distance before this union the anterior branch is connected by a crossvein with the posterior branch of the preceding vein; the other vein extends along the posterior margin of the wing neary to its middle, then unites with the posterior fork of the preceding vein; veins bearing several stout bristles; halteres distinct; front femora considerably thickened, their tibiæ rather slender, femora rather robust, once and a third as long as the front ones, their tibiæ as thick as and nearly twice as long as the front ones, hind femora and tibiæ more slender than and nearly twice as long as the middle ones, each femur bearing several bristles, the tibiæ destitute of bristles; first four joints of the front and middle tarsi subequal in length, each slightly broader than long, together slightly longer than the fifth, which is considerably swollen; first joint of the hind tarsi twice as long as wide, as long as the two succeeding joints, the last joint swollen, as long as the three preceding ones; each tarsal claw bears a large lobe at the base of the under side.
