Abdomen black, strongly pilose, with the posterior segmental borders narrowly ochraceous. Underside of body and legs luteous ; base and central fascia to face, inner margin of eyes, some irregular marks on sternum and near coxae, a linear streak on each side of femora, a spot on trochanters, a marginal segmental row of spots to abdomen, and a large quadrate spot on apical segment fuscous.
