Triepeolus helianthi Robertson. Lethbridge, Aug. 11 (G. A. Mail.) Described from Illinois, but known to be widely distributed.

Triepeolus stricklandi n. sp.

♀. Length about 8 mm.; black, including mandibles (except a dull red band in middle), antennae, tegulae (except red spot on outer side) and legs (except small joints of tarsi, which are red) ; eyes pale green, with a purplish suffusion below; pubescent markings pale cream-colour, pure white in region about antennae, the under side of abdomen without light markings; spurs black.

The following is a report on certain specimens of Ichneumonidae found in a small collection of Hymenoptera made by Mr. J. A. Guignard of Ottawa, Ontario, and recently acquired by the writer, for the Canadian National Collection, through the kindness of a relative of the late Mr. Guignard.

This subgenus has a rather peculiar distribution, one species having been described from equatorial Africa and one from Europe. It is therefore of interest to record a new species from Ithaca, N.Y. The following key will serve to distinguish these species.

The specimens upon which this paper is based were received from various parts of four Western States. Those of the first lot were from South Dakota and were sent to the writer by Prof. H. C. Severin of Brookings, S. Dak. Among these was one specimen labeled “Rivellia sp. n.?” by the late Dr. J. M. Aldrich. Later, other specimens were received from H. E. Jaques, Iowa; C. W. Sabrosky, Kansas; Maurice James, Colorado; and one specimen from North Dakota, received from C. E. Mickel.

In the last few years, Lepidopterists have devoted a great deal of interest to the genus Euphydryas. This interest, however, has resulted in a great many valid and invalid names, but in little organization or understanding of specific variation and interrelation. Gunder (Pan Pacific Entomologist, VI, 1-8. 1929), in a carefully prepared and well illustrated paper, made the mistake of lumping all American species under five specific names, which is taxonomically incorrect, regardless of genitalic similarities (Pan-Pacific Entomologist, XI, 144, 1935).

The females of these two species are markedly different in colour, yet the males resemble each other so closely that Bradley (1913) was unable to distinguish between them. Waterston (is Chrystal, 1928) separated the males by the proportions of the hind metatarsus ; that of U. albicornis F. was “barely five times as long as broad,” while in U. flavicornis F. the metatarsus was “nearly seven times as long as broad.” However, Waterston had but two males of one species, and the metatarsal proportions vary intraspecifically ; on this account, the value of the character cannot be determined without a long series.

Length 5-7 mm. Elytra black with margins yellow-brown, prothorax with rather wide margins, brown, disc black with the usual pale apical spots common to the genus. Legs, antennae and ventral surface black. Antennae stout with the usual needle-like appendage to the terminal segment. Prothorax wider than long, the translucent areas irregularly shaped anrl rather large, the disc convex, black, with the central portion not punctate, shining, the margins reflexed as is usual in the genus. The hind angles of the prothorax are narrowly rounded.
