Character of the Genus. 



Larva chilopodomorphous, linear, lengthened, provided on each 

 side with ten long, attenuated, spreading, brachiform appendages 

 of nearly equal length, consisting of a mid-rib and lateral beards, 

 d?creasing in length towards the extremity, and imitating the struc- 

 ture of a very delicate plume, being armed with a terminal spike, 

 composed of dense whorls of short robust spines. Feet agreeing 

 in number with those of the other larvse of this tribe; short minute 

 and entirely concealed by the lateral appendages. 



ChrysaUs short, angular, attenuated at both ends, with two sides even, 

 and the third gently swelled and rounded ; consisting of two unequal 

 pyramidal portions, the terminal being longest, and provided with two 

 points, while the angles are armed with a few short spines, which are 

 more robust at the union of the two pyramids : the longitudinal and 

 transverse ridges ornamented with a delicate golden streak. 



Perfect Insect : AntcnneB of very great length, slender, filiform at the 

 base, beyond the middle very gradually incrassated to a long cylindrical 

 abruptly terminated, slightly curved capitulum. 



Palpi of moderate length, slightly projecting beyond the head; 

 second joint greatly lengthened and increasing in breadth exteriorly; 

 third joint minute. 



Proboscis of moderate length, robust, compressed towards the ex- 

 tremity and provided with delicate lateral, spreading cil\?B. 



Wings: anterior pair somewhat triangular, with a lengthened boldly 

 curved costal and somewhat excavated posterior margin ; hinder pair 

 rounded, very slightly attenuated, obtuse, repand or slightly notched.
