Allantus cingulatus is a largely black species with an off-white to yellow band on the abdomen. In the female the fifth sternite is also pale and in the male at least flecked with pale. The coxae are white. The hind femora are dark and the hind tarsus is infuscated so as to be clearly darker than the apex of the tibia. The scutellum is shining in the middle with punctures largely confined to the edges. The apex of the clypeus and the base of the mandibles are off-white.
Larvae feed on roses and strawberry plants. In Europe, also on hazel and birch.
