described since two descriptions of it have appeared. One will be 
found in Harris’ Insects Injurious to Vegetation” the other in “ Dr. 
Morris’ recent Synopsis of the J.iepidoptera of North America,” but 
these descriptions do not agree with each other, hence further evidence 
is necessary to settle the point. The subjoined description will be 
found to agree most closely with that of Harris, and observations on 
this species for three successive seasons convince me that no striking 
variations in the larvae occur. 
Length two and a half inches. Head bilobed, black and shining, 
reddish at the sides. Body black with a brownish shade on sides 
towards under surface. Each segment with an irregular transverse 
row of elevated tubercles from which spring tufts of rigid black shin¬ 
ing hairs. The spaces between each segment from fourth to tenth 
inclusive are banded with red, bands wider and more conspicuous from 
sixth to ninth. Color of underside varies from reddish to yellowish 
brown, feet reddish, legs brown thickly clothed with short hairs. 
These larvae attain their full growth in the fall and hybernate through 
the winter under logs, the bark of decayed trees, &c. When aroused 
from their torpor by the warmth of spring they feed a little on grass 
or almost any other green thing they meet with before going into 
chrysalis. I have found them in the fall feeding in the wild sunflower 
{Helianthus decapetalus.) 
Catocala concumbens, Walker, C. B. M. 1198. 
Length two to two and a half inches, onisciform. Head flat, dark 
greyish intermixed with red. Upper surface dirty brown with a light¬ 
ish chain-like dorsal stripe and a very small fleshy protuberance on each 
side of this stripe on each segment. On the ninth segmenf is a small 
protuberance of a brownish color and on the eleventh a mark resem¬ 
bling an oblique incision. A thick lateral fringe of short hair close 
to the under surface. Under surface pinkish with a central row of 
round black spots which are larger about the middle of the body and 
much smaller towards the extremities.
