The middle tibtae apart from the pair of great spurs, are always spinu- 
lated; generally much more heavily in the Cafadéap/a, than in the Catocala 
group. 
The hind tibiae are sometimes spinulated, sometimes not. Always 
and generally heavily, in the Ca/adap/a, not at all, or but slightly, in the 
Catocala group. Many of the fore tibize are heavily covered with long hairs 
on the inner side. So also on the middle tibiz, which on the males, in 
many species form large tufts. This however, is simply a tendency, very 
frequently found among the lower /Vocfwidae. After diligent and repeated 
search, with a compound microscope, on scores of denuded legs, I have 
not yet found the faintest suggestion of the scent organs spoken of by Prof. 
Lintner in his Report, p. 71 as found “at the upper part of the second 
pair of tibize.” 
The /ars? present no special modifications. In length, as: is usual, 
they vary as compared with each other. I have found a curious monstro- 
sity in the tarsi of the fore leg of a specimen of consors. At the joint 
below the second segment from the tibia, two segments proceed, forming 
a double leg at the end. . 
The claws present marked and surprising variation, In the greater 
number of the species, they are single, rather stout, and curved strongly 
downward. From this they reach one way to the slender semicircular 
claw of A#essalina, and the other way, to the form found in zudilis, elo- 
nympha, and gracilis, where the curve becomes almost rectangular on 
the outer edge, and on the inner side there is developed a thin angular 
membrane, (the counterpart of that in the claw of the lower Noc/ude), 
giving a distinctly bifid appearance. There is also a difference in what 
may be called the heel of the claw. In some, (zubilis, elonympha, gracils) 
it is obsolete; in AZessaiina it is strongly prominent. I refer to the proper 
figures of the plate. 
POSITION OF THE GENUS. 
In view of what has been already said, it will be seen that from al- 
most every point of view, the genus occupies a position between the 
typical Moctudd and Geomefer. In my opinion, it is nearer the latter, 
than the former. And while, on the basis of venation, it must yet be 
classed among the Noctuide, it ought to be placed closer to the foot 
of the list than it is; very close to, if not by the side of Ypsza (Homoptera),
