Altliougli this is lueutioiied as the first subfiuuily 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 reduction. The absence of a cremaster, and the simplicity of form in the pupa, and the suudl, 

 feeble palpi and small head of the imago nmy be due to reduction of these itarts.

Ilead rather small, not prominent; front broad in S , narrower in 2 , rather full, with loose, 

 uneven, long scales; no tufts at the base of the anteniue; eyes with long, rather dense, hairs in S 

 and 9 . Antenna^, shorter than usual, curved inward, with long pectinations extending to the 

 tip; in 9 the pectinations short, increasing in length to the middle; the npjier side, including the 

 pectinations, densely scaled. Pali)i 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 protliorax not forming a "collar," but continuous with those 

 behiuti or with a well marked median crest. 



Wings: Primaries rather short and 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 vennleniot 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 veuule varying much in length, usually very .short. 



Legs: Femora and tibiie clothed with long dense hairs, spreading out on each side. 



Abdomen short, tapering in $ rajiidly to the end; in 9 thick, heavy, and obtuse at the end. 



In coloration the species somewhat recall those of Cerura, being whitish gray, and often 

 having a straight broad median baud 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 more persistent than 

 even the structural characters. 



The genus is readily identified bj- the short, small, feeble palpi, the hairy eyes, the well 

 pectinated antenna', and the short, broad tore wings. 



Structurally (iluphisia is in many respects the simplest genus of the group, its larva being 

 noctuiform and without any projections. The larvre are often, perhaps usually, even, without any 

 red spots. G. septenirionis [trUincaia Pack.) is the tyjiical, and appears to be the more 

 generalized, species. 



Efjg. — Low, flattened, hemispherical, much smaller than iu any (^thcr known genus of the- 

 family; surface of the shell smooth ; green.
