Imago. — Male. Forewing elongated, triangular ; costa arched, apex rounded, 

 exterior margin veiy oblique and even, posterior angle obtuse, posterior margin 

 very short; cell long, extending to two-thirds the wing, broad; costal vein 

 extending to three-fourths the margin; first subcostal branch emitted at about two- 

 sixths and second branch at one-sixth before end of the cell, third branch from end 

 of the cell, arched, fourth and fifth branch at about one-half beyond the cell ; upper 

 discocelhilar shortest, straight, second slightly recurv^ed, upper I'adial from the angle, 

 lower radial from end of the cell, forming a fourth median branch, second and third 

 medians v/idest apart ; snbmedian recurved from its base, its lower branch rather 

 long. i?in(i/rm(7 very short, elongated posteriorly ; exterior margin slightly convex 

 anteriorly and truncatedly rounded posteriorly, slightly scalloped ; abdominal margin 

 twice folded broadly over on to the upperside, and there forming a lengthened flat 

 triangulate lappet, which covers an elongated patch of androconial downy-scales placed 

 between the snbmedian and anal angle ; edge of abdominal margin fringed with long 

 fine hairs. If the abdominal lappet is unfolded the wing is then somewhat quadrate 

 in shape; precostal vein long, bifid, its inner branch short and truncate, outer branch 

 long, joining the costal vein and forming an elongated basal-costal cell ; costal vein 

 much arched ; cell very long, extending to nearly two-thirds the wing; first sub- 

 costal emitted at fully one-half and second at one-fourth before end of the cell ; disco- 

 cellular very short, the radial and upper median branch being emitted close together ; 

 lower median at one-fourth before lower end of the cell, and outwardly curved ; 

 submediun vein much recurved and widely separated from the lower median branch.
