34 REVISION OF GENUS CUCULLIA—SMITH. 
veins are more or less obviously black-lined, and there is a strigate ap- 
pearance, varying in degree. The ordinary lines are never complete, 
and the t. a. is often wanting altogether except in the submedian inter- 
space. No detailed reference is made in the descriptions to these com- 
mon characters, more emphasis being put on those characters which 
really distinguish the species. 
A few only of the forms are really common; but some species, usually 
not represented in collections, are undoubtedly missing because their 
distinctness has not been recognized. Postera and florea as distinct 
from asteroides are examples, and probably the three will be found to 
have the same distribution. 
The t. a. line is, in most of the species, traceable in the submedian inter- 
space, where it forms a long outward projection or tooth, nearly reach- 
ing the middle of wing. Quite usually, where this is discernible, there 
is also a fine, black longitudinal line from the base to the end of this 
tooth. At first sight this outline has a strong resemblance to a clavi- 
form; but in the few species in which that feature is found, it is attached 
at the end of the tooth and reaches thet. p. line. Usually this same 
line is again marked on the inner margin by a black dash or line ex- 
tending outwardly. 
It is quite notable that we have no species common to both sides of 
continent, but that, except convexipennis, every one of the eastern species 
has a close ally in Colorado. Thus asteroides, postera, and florea are rep- 
resented by montane, similaris, and obscurior ; speyeri and intermedia by 
dorsalis and cinderella. Serriaticornis is the only Californian form 
known to me, though Dr. Behr has named a C. solidaginis which can not 
be recognized from the description. 
Laetifica is from Arizona and Texas, and is the only southwestern 
form known to me. 
Easily distinguished from all the other species known to me is serra- 
ticornis. The antenna in the male are distinctly toothed, the lateral pro- 
cesses furnished with a bristly tuft. This character is a remarkable 
one for the genus, and is accompanied by an equally divergent sexual 
structure. Should the species find strictly congeneric allies it may be 
eventually separated from Cucullia. In color it is ash gray, quite 
strongly resembling a small speyert, or yet more nearly a small letifica. 
I have seen no female, and Dr. Lintner in his original description had 
only males before him. As already stated, it is the only Californian 
species known to me. 
Of the species with simple male antenne, convexipennis differs in 
color from all the others. Through the center of the primaries the — 
Shade is a peculiar yellow ash-gray ; from the middle of the costa to 
the outer margin at vein 4, a leather-brown shade suffuses the wing 
and darkens decidedly toward costa. <A similar shade extends from 
the middle of the inner margin to the outer margin at vein 3, cut | 
by the pale s. t. line, which is elsewhere marked on the costa only. !
