LEPIDOPTERA HETEROCERA. 1383 



breviores, late pectinatse, dimidio fere apicali mediocriter pectinate 

 Abdomen alas posticas paullo superans. Pedes validi, pilosi; tibiae 

 postic33 calcaribus duobus apicalibus minimis. Alae ani^ustae ; an- 

 ticae longiusculae, apud costam subrectae, apiee subacuminatae, mar- 

 gine exteriore perobliquo vix convexo. 



Male. Body stout. Proboscis not visible. Palpi very short, 

 not extending so far as the head ; third joint very small. Antennae 

 a little shorter than the thorax, deeply pectinated for nearly two- 

 1 thirds of the length, moderately pectinated from thence to the tips ; 

 branches ciliated, very numerous. Abdomen extending a little 

 beyond the hind wings. Legs stout, pilose ; hind tibiae with two 

 minute apical spurs. Wings narrow. Fore wings rather long, 

 nearly straight in front, slightly acuminated at the tips, extremely 

 oblique and very slightly convex along the exterior border ; first 

 and second inferior veins almost contiguous at the base ; third very 

 remote. Hind wings about half the length of the fore wings. 



This genus seems to be more nearly allied to the Saturniidce 

 than to any other family. In the Synoptic table, p. 1200, it agrees 

 with JEacles, but differs much from that genus in several characters. 



1. Phaneta divisa. 



Mas. Cervina ; thorax, pectus et pedes nigro varia ; abdomen 

 nigricans vitta testacea, subtus testaceum vilta nigricante ; alee 

 basi nigro conspersce, fascia interiore angusta perobliqna nigra 

 extns albido diffuse marginata, lunula discali vitrea, fasciaque 

 submarginali albida extus nigro marginata ; antica? apud 

 costce dimidium apicale nigricantes.

 with a few of the same elsewhere ; a very oblique black band on the 

 inner side of the vitreous lunule, this band in the fore wings is 

 continued along the costa to the tip, it is accompanied on the outer 

 side by a diffuse whitish band, and the latter at each end joins the 

 submarginal whitish band, which is bordered with black on the 

 . outer side ; ciliae with two brown bands. Length of the body 7
