PHEYGANID.E. CH^.TOPTERYX. 233 



narrowed at the base, dilated at the apex, of the female longer, more robust 

 and very obtuse : legs long, rather stout : femora simple : tibiw and tarsi 

 furnished with numerous short spines, the former with a pair of spurs at the 

 apex of each, and the four hinder ones each with a second pair below the 

 middle. 



The insects of this genus may be known, not only by a slight 

 diversity in the form of the palpi, but especially by having the 

 anterior wings very broad, granulated, beset throughout with rigid 

 erect bristles, very pubescent, and rounded at the apex : in fact, 

 their entire habit is very dissimilar to that of any other genus of this 

 family : two species only are known.
