This species is related to I), allicollis, CHR. and especially the var. inireicollix. 

 LEP., but that species may be known from it by the hair on the apex of the abdomen 

 being black, and by the wings being uniformly blackish.

 pile is dull rufous; the abdominal segments with while hair bands, the calcaria while, 

 the tarsal spines black; wings fuscous, the apex of costal and radial cellules dark fuscous 

 violaceous; the whole wings iridescent, tinged with violaceous; apex of radius straight,
