Body broad, very short, pitchy varied with dark ferruginous; head as broad as the chest; crown very slightly arched, with a slight longitudinal ridge and with a rim on the border; its breadth more than six times its length; front scutcheon-shaped, slightly rugulose, bordered by a rim, slightly concave where it joins the epistoma, its breadth almost twice its length; epistoma short, nearly triangular; mouth ferruginous; middle-chest much longer than the fore-chest, almost triangular, with two oblique ridges; hinder sides slightly concave; breast, hind-chest and abdomen bright red, the latter obconical, a little longer than the chest; laminae pale straw colour, powdered with white; legs black, hind-thighs red with black tips; hind-shanks dark ferruginous, armed with three long stout spines; fore-wings ferruginous, black along the fore border and at the tips and partly along the hind border; a few ferruginous dots in the black part; a tawny spot on the hind border and two large colourless spots near the tip which is bristly; veins ferruginous, black towards the tips; hind wings blackish with a white spot near the tip of the fore border; veins black.
