|Abstract||Atra velutina; abdomine annulo basali aurantiaco; antennis, palpis, pedibus halteribusque nigris ; alls fuscis, maculis sublimpides in cellularum medio. — ♀. Long. 20,5 mm.|
Closely related to the two foregoing species; the thorax, however, is entirely black; on the contrary the posterior half of the first abdominal segment and the anterior half of the second one are orange. The wings are not so broad and less dark; all the cells, except the costal ones, have clear centres; neuration agreeing with that of incunctans and velutina.
