This species may be recognized by the fact that the wings are 

 broadly fuscous to near the apex of the clavus with the apex milky 

 subhyaline, thickly spotted with fuscous and by the distinct genitalia. 



Vertex crescent-shaped transverse, broadly rounded before, not 

 reaching the frons ; frons longer than the clypeus, strongly narrowed 

 between the eyes; lateral carinas of the mesonotum strongly diverg- 

 ing; pygofer of the male short, ventral tooth elongate, acute, genital 

 styles narrow at the base, widely separated, meeting apically, their 

 apices broadly expanded and reflexed, reaching the anal segment ; 

 anal segment narrow, not produced. 



Color : General color of the body blackish fuscous ; earinae of the 

 frons and posterior margin of the pronotum yellowish testaceous; 

 fore wings blackish fuscous on the basal half with clavus darker, al- 

 most black on the costal margin, paler and brownish internally; the 

 apical portion of the wings milky subhyaline, more or less spotted 

 with fuscous ; there are three distinct fuscous spots on the costal mar- 

 gain; the middle one continued as an interrupted fuscous band to- 

 wards the apex of the clavus, the longitudinal veins with some tri- 

 angular fuscous spots on the apical margin ; basilar angles narrowly 

 pale yellow; legs testaceous yellow; the fore femora fuscous; ab- 

 domen fuscous ; the apex of the genitalia testaceous yellow.
