Imago. — Male. Forewing large, elongated, triangular; costa slightly arclied, 

 apex rounded, exterior margin very oblique, and more or less waved, posterior 

 margin short and very slightly recurved ; costal vein extending to fully three-fourths 

 the margin ; first subcostal branch emitted at one-half and second at one-fourtli 

 before end of the cell, third from the end or at a very short distance beyond end of 

 the cell and terminating at the apex, fifth at about one-third beyond tlie cell from 

 below the fourth ; the cell extending to beyond half the wing, the false-veins or 

 longitudinal folds within the cell fairly distinct ; discocellulars outwardly- oblique, 

 upper shortest and straight, lower concave, the upper radial from their angle; the 

 fourth or upper median branch from lower end of the cell, third median at about 

 one-seventh, the second at one-third, and first at one-half before end of the cell; 

 median and submedian vein connected by a short transverse veinlet near the base ; 

 submedian vein with a short subbasal lower veinlet extending obliquely outward to 

 the posterior margin, llimlwing short, small in proportion to the forewing, 

 subtriangular ; anterior margin slightly arched; exterior margin rounded and 

 scalloped ; abdominal margin, in the male, with a longitadinal fold or ■pouch extending 

 along the submedian vein, and, Avhen opened, digcluKing a dciischj-iMclied mass of 

 doivny androconial hairs, occupying the area between the sul^median and the extreme 

 margin, this pouch being usually closed or only ti-aced by a pale line down the 

 submedian vein ; precostal vein two-branched, the inner branch curs'ed, the outer 

 branch uniting with the costal vein and thus forming an interno-basal costal cell ; 

 upper discocellular outwardly-oblique, second short, the radial from their angle; 

 middle median branch at about one-fifth and lower at one-third before end of the 

 cell ; submedian vein recurved ; abdominal marginal hairs long. Ilvadj and eyes 

 large ; thorax very stout, woolly ; abdomen long, stout, compactly scaled ; males 

 furnished with two large anal valves ; palpi small, hairy, pi^essed to the head ; legs 

 long, strong, fore tibia w*ith a very stout lateral spur about the middle; tarsal claws 

 simple ; antenna3 very long, gradually clavate, the club slightly tapering towards the 

 apex, and slightly curved. 



Larva. — Cylindrical, with two dorsal rows, and anterior and lateral rows of 

 fleshy tubercles ; a retractile pair of tentacula (osmateria) situated behind the head. 



Pupa. — Stout; arched backward anteriorly; thorax conical, the top ilattened
