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, 
decreasing 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 larve of this tribe; short minute 
and entirely concealed by the lateral appendages. 
~ Chrysalis 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: Antenne 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 ciliz. 
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.
