 pressed line on each extreme side. Wings dark fuscous, slightly paler 

 at tips; just beyond the middle of the anterior wing, a broad hyaline 

 band, commencing at the base of the stigma, which has a slight whitish 

 dot, and extending all the way across the wing, occupying almost the 

 whole of the first submarginal cell ; this band is somewhat irregular, 

 and the nervures divide it into three spots, of which the lower one is 

 smallest, oblong and slightly oblique ; just within the middle of the 

 posterior pair, a large, quadrate, hyaline spot. Legs black, tinged with 

 piceous ; their coxae rufo-ferruginous, their trochanters rufous at tip. 

 Abdomen elongate, convex, subclavate, smooth and polished; first and

 segment, running parallel with the sides of the segment; on each side 

 of the third segment a rather deep oblique groove diverging posteriorly ; 

 remaining segments smooth, without impressed lines; sometimes the 

 abdomen is pale ferruginous, with the apical margins of the third and 

 following dorsal segments and the apical ventral segments, rufous or 

 sanguineous; ovipositor more than half again as long as the body, 

 piceous. valves black. Length 8? lines; expanse of wings 16 lines.

This is a large, elegant species, easily recognized by the hyaline spots 

 on the wings.
