This is at the same time the handsomest and most widely distrib- 

 uted of our species of this genus ; it is found everywhere where the 

 o-rape grows, but is rarely abundant enough to do mischief, though 

 it figures in the literature of economic entomology. 



The side piece of the % is shorter and broader than in jjandorus, 

 and there is a decided enlargement at the insertion of the clasper, 

 which is more curved and somewhat longer than in pandoras. 



There is little variation in the imago, which is so different in color 

 from the others of the genus as to be readily recognizable. 



The early stages of this species are also well known. Prof. Riley 

 has figured the larva and imago, and these figures have been freely 

 used by others, and Mr. Lintner has given, perhaps, the most com- 

 pletely written history of the species.

Head small, the vestiture forming a central ridge or tuft between 

 the antennte; tongue about half the length of the body; palpi mod- 

 erate, curving up and rather closely applied to the front; eyes mod- 

 erate in size, and slightly la.shed ; antennae slim, fusiform, the tip 

 attenuated and prominently curved or hooked, biciliate in the males 

 simple in the females. Thorax short and stout, but little advanced 

 in front of the base of primaries, untufted, vestiture smooth. Ab- 

 domen large, cylindrical, tapering i-atlier suddenly on the last seg- 

 ments ; without anal or side tufts, segments without spinules along 

 the hinder edge ; some specimens have a few fine spinules ; tibiae not 

 sjtinose, except in chcerilvs, which has the fore and middle pairs 

 sparsely spinose ; middle tibite with one jiair of comparatively long, 

 unequal spurs, the hind tibire with two pairs. Primaries with eleven 

 veins (10 wanting), not differing in jjattern from the family type ; 

 apex falcate, outer margin excavate from apex to vein 4 and rounded 

 beyond. Secondaries with the typical venation ; outer margin ex- 

 cavate between veins lb and 3, but nearly straight beyond this to 

 the apex. Costa of all the wings arcuate. Frenelum and loop 

 present in the males, the loop wanting in the females, the frenelum 

 reduced to a bunch of bristles. 



The genitalia of the males are all of one type, differing only in 

 minor characters in the species. The side piece is short and broad, 

 irregularly oval in shape, with a variously formed, small corneous
