DETAILED ACCOUNT OF GENERA AND SPECIES. 

 PANTHEA Hubner. 

 Panthea Hubneh, Verzeichniss, 1816, p. 203. 



Plump, robust species, with retracted head, short quadrate thorax, 

 long, stout, cylindrical abdomen, and large, trigonate, pointed primaries. 



The head is broad, retracted, front flat, eyes widely separated, all the 

 sutures obscured. Ocelli very small, coucealed, somewhat remote from 

 the extreme posterior angle of the eye. Tongue short and weak. Palpi 

 small, slender, hardly extending to the front and practically invisible 

 from above. Antennae heavily and rather lengthily bi pectinated in 

 the male; simple in the female. Eyes hairy, without lashes. 



The thorax is quadrate, rather wider than long, with smooth, hairy 

 vestituie, which is somewhat loose, but marks the collar and patagiae, 

 and seems somewhat abruptly cut oft' posteriorly. 



The legs are short, stout, very much of a size, clothed with rather 

 long, loose hair. They are unarmed, except for the usual spurs which 

 are short and rather weak. All the tarsal claws are simple in the 

 species examined. 



The abdomen exceeds the anal angle of the secondaries in both 

 sexes, but in the female is much the longer, plump, and cylindrical. 

 There are no tufts. 



The wings are large, well clothed with scales, and are set well forward
