THE CANADIAN ENTOMOLOGIST. 161 



Cryptophagidns (Journ. N. Y, Ent. Soc, VIII), I have since obtained 

 single specimens from Vicksburg, Miss., Alexandria, La., and Del Rio, 

 Texas. 



In my revision of the American Coccinellidfe (1. c, VII) I erected a 

 new genus — Neomysia — for the species of our fauiia usually called Mysia, 

 and, although I am now inclined to think that there is really no generic 

 difference between our species and the European, the name Neomysia 

 will, nevertheless, have to be applied to both, as Mysia is a preoccupied 

 name. In the genus Zagloba (1. c, p. 113), the two forms described under 

 the names I'aticollis and orbipetinis seem to be merely varietal in nature, 

 although the material in my cabinet is too scanty to base any final judg- 

 ment upon. As stated by Mr. Fall, my Exochomus ovoideiis (p. 107) 

 should be regarded as a synonym of desertoriim ; the locality label on the 

 former specimens is undoubtedly erroneous ; they may have been taken 

 in Colorado, in which region much of Dr. Levette's material was collected. 

 Nephaspis brtinnea seems to be the female of Gorhami (p. 168), and the 

 name should therefore disappear in synonmy. It is my desire, in the 

 near future, to revise again our species of Scymmts, as the table published 

 in the paper mentioned is far from satisfactory in many respects. 



Liobaidius spectans, Csy., described in the preceding volume of this 

 journal, is closely allied to the Central American Antkicus clavicornis, 

 Champ., differing principally in having the elytra punctate only in the 

 transverse subbasal depression and not striato-punctate in basal third. 

 Impressipennis, Laf, described from Texas, which also appears to be 

 allied, differs in coloration and in its much more elongate elytra. No 

 species closely allied to Fronteralis is alluded to by Mr. Champion in the 

 " Biologia." 



Vanonus, Csy. 



Renewed observation upon the material in my collection seems to 

 prove that those examples having the under surface of the hind femora 

 densely papillose and the antennas evenly and gradually enlarged distally, 

 are males, while those without the femoral pad, but with a strong sub- 

 apical lamelliform tooth on the under side of the hind femora — the 

 antennae having an abrupt pentamerous club — are females. It may be 

 said, at least, that where the male spicule is visible at all, the femora are 

 papillose, and, in the only case before me where the sex is evidently 

 female, the femora are simply toothed. In my previous work (Col. Not., 

 VI:, p. 791,) I took it for granted, to some extent, that the remarkable
