Heteralonia (Acrodisca) umbrosa (Loew, 1860)

Wings intensly infuscated dark blackish brown throughout, with a violaceous tint and with the clearer areas or streaks in the cells faint, the infuscations along the veins thus not conspicuous and spots not conspicuously evident.
Scaling on abdomen above composed mostly of black ones discally and along lateral margins and conspicuous, dense, snow-white ones in very broadly interrupted transverse bands, which are more or less partially complete only across base of tergite 2 and across 6 and 7.
