THE CANADIAN ENTOMOLOGIST 231 



This remarkable genus is dedicated to G. H. Verrall, whose writ- 

 ings are invakiable to students of fossil Diptera, although he studied 

 only living forms. In Williston's table (N. Am. Diptera, 3rd. Edit.) 

 it runs to 29, and the wings, except for the anal cell, show a rather 

 close general resemblance to those of Lepidophora. In Legnotomyia 

 the anal cell is as widely open on the wing margin as the third pos- 

 terior, but these cells are not nearly as wide as in Verrallites; the 

 discal cell in Legnotomyia is also much shorter than in the fossil, and 

 there are other important differences. From all the genera of fossil 

 Bomlyliida? from Florissant, Venallites is easily known by the form 

 of the anal cell. 



We are still without a single Tachinid or Muscid s. str. from 

 the Florissant shales. Glossina alone (two species) represents the 

 whole series of Calyptrate Muscoids! In Coleoptera, we are still 

 without a Histerid or Cicindelid. A Cypris is, so far, the sole 

 representative of the Crustacea. The total number of species 

 described is now so great that these blanks become significant. In 

 the Neuropteroid series we have plenty of Ephemerids and Ter- 

 mites; numerous Raphidiids, Chrysopids and Hemerobiids; a 

 Nemopterid and an Embiid;but as yet not a single Perlid. The 

 Panorpids are represented by three species. We have no less than 

 five species of the Dipterous family Nemestrinidoe, now so rare in 

 this country. The quite numerous Bombyliidje, as well as the 

 very numerous Aphididae, all belong to extinct genera; but the 

 Phoridae, Syrphidse, Therevidae, Leptidae, etc., are referable to 

 genera still living. 



Hymenoptera. 

 Alysia ruskii, n. sp. 

 9 — Robust, length almost 5, mm.; anterior wings broad, 

 broadly rounded at apex, nearly 4 mm. long; expanse about 9 mm.; 

 head and thorax black ; base of abdomen (apparently two segments) 

 clear ferruginous, the rest black or dark brown; antennae nearly 3 

 mm. long, dark, thick, the joints just before the end about as broad 

 as long, with a diameter of about 110 microns; legs ferruginous, the 

 hind femora incrassate, suffused with dark brown, the base broadly 

 and apex more narrowly pallid; hind tibial spur long and sharp; 

 head and thorax apparently closely but shallowly punctured;
