Castnia closely resembles the Hesperians, though much 

 larger. The species are of large size and of brilliant hues, and 

 fly in the day time, like the butterflies. The head is, however, 

 much narrower in front, and the antennae inserted higher up. 

 The larva is a borer, living in the stems of Orchids ; it is not 

 known, but probably has the usual form of boring caterpillars, 

 tiiid the pupa is said by King to resemble that of Cossus. 



Alypia comprises black moths, ornamented with white and 

 yellow patches on the wings. The antenme are long, and a 

 little thickened in the middle. The wings are short and broad. 

 The body of the pupa is not contracted at the base of the 

 abdomen as in Eudryas. The larva feeds on the grape and 

 constructs an earthen cocoon, like that of -ZEgeria, according 

 to Harris. A. octo-iim<-ii/<tt<t Fabr. is black, with eight spots. 

 two on each wing, those on the fore wing being yellowish, those 

 on the hind wing white. 



The genus PsycJiomoiyha is allied to Alypia, but differs in 

 the broadly pectinated antenme, and the shorter palpi, which 

 do not pass beyond the front of the 

 head. P. epiniaii* Drury (Fig. 211) is 

 found from Connecticut southwards. 

 It is black, with a broad, yellow, white, 

 irregularly lunate patch crossing the 

 outer third of the wing, and on the un- 

 der side is larger, being triangular, 



with two square black spots connected with the costa ; on the 

 hind wings is a little larger, mostly regular crescent-shaped 

 brick-red spot; it expands 1.10 inches. Doubleday (Harris 

 Correspondence) states on the authority of Abbot, that the 

 larva feeds on Bigiionia radicans, in (ieorgia. "It is pale, 

 with black lines, and though having the full complement of 

 legs, seems to be a semi-looper in its walk, like Brephos." 



Eudryas is a peculiar form, gaily colored, and easily known 

 t 'y the densely tufted forelegs, and the short tufts of metallic 

 scales on the thorax and abdomen. The antenmv are filiform, 

 and the abdomen is tipped with hairs. The larva of E. grata 

 Fabr. is gaily colored with orange and blue, dotted with black. 

 The body is long and widens towards the eighth ring, which is 

 humped, from which the body rapidly narrows to the tip.
