NORTH AMERICAN LEFIDOPTERA.

This is one of the most interesting species I have studied, and will 
not remain in the genus in which I have placed it despite its strong 
habital resemblance to both standingeri and Colorado. The eyes, 
while narrowed, are scarcely as constricted as in the type of the 
genus, the fore tibiie are somewhat flattened and very heavily armed, 
with longer sjiines at tip, and, finally, the front shows quite a long, 
conic, corneous |)rojection, which is evident in neither of the other 
species. It really agrees better with my genus Chorizagrotis, but 
the form is not depressed, the eyes are narrowed, and the fi’ontal 
jirotuberance is quite different. It has little or no habital resem- 
blance with Chorizagrotis, and I think it best referi-ed for the j)resent 
to the genus which in appearance it most resembles.
