Altlioiigli this is mentioned as the first subfamily of the group, it is, contrary to my former 
opinion, probably a side branch, rather than a primitive group. The smooth larva may be a case 
of reductiou. The absence of a cremaster, and the simplicity of form in the pupa, and the small, 
feeble palpi and small head of the imago may be due to reduction of these parts.

Head rather small, not proininentj front broad in S , narrower in 2 , rather full, with loose, 
uneven, long scales; no tufts at the base of the antennae; eyes with long, rather dense, hairs in 6 
and 9 . Antenme shorter than usual, curved iuward, with loug pectinations extending to the 
tip; in 9 the pectinations short, increasing in length to the middle; the upper side, including the 
pectinations, densely scaled. Palpi small, feeble, slender, cylindrical, with rather long hairs, not 
very distinct from those of the front; the end of the palpi themselves depressed, not reaching 
the front. 
Thorax smooth, the scales of the prothorax not forming a ‘‘collar,” but continuous with those 
behind or with a well maiked median crest. 
Wings: Primaries rather short ami broad, a little more than one-half as broad as long; costa 
straight, a little convex toward the somewhat pointed apex; outer margin oblique, a little shorter 
than the internal. Hind wings reaching, when spread out, to near the end of the abdomen; costa 
straight; apex produced and slightly pointed; outer margin bent a little in the middle and so as 
to be parallel with the costa of the fore wings. 
Venation: Fore wings, first subcostal venule not uniting with the main vein at the origin of 
the fifth venule to form a subcostal cell; the third subcostal venule very short, arising very near 
the apex, at or near the outer third of the fourth venule. 
Hind wings with the first subcostal venule varying much in length, usually very short. 
Legs: Femora and tibim clothed with long dense hairs, spreading out on etich side. 
Abdomen short, tapering iu 8 rapidly to .the end; in 9 thick, heavy, uml obtuse at the end. 
Ill coloration the species somewhat recall those of Cerura, being whitish gray, and often 
having a straight broad median band on the fore wings, of which the outer side is somewhat wavy, 
and bent just before the fourth median venule. The hind wings are nearly white. The style of 
markings is substantially the same in the two sections. of the genus, and is luoi'e pei'sistent than 
even the structural characters. 
The genus is readily identified by the short, small, feeble palpi, the hairy eyes, the well 
pectinated antenme, and the short, broad fore wings. 
Structurally (xluphisia is in many respects the simxdest genus of the group, its larva being 
noctuiform and without auy projections. The larvie are often, perhaps usually, even, without any 
red spots. G, septentrionis [trilincata Pack.) is the typical, and appears to be the more 
generalized, species. 
Eg<j. — Low, flattened, hemispherical, much smaller than iu any other known genus of the 
family; surface of the shell smooth; green.
