The genus of bees consists of generally small, black-and-yellow or black-and-white wasp-like species. The resemblance to wasps is enhanced by the absence of a scopa, which is atypical among bees. The body form of this genus is described as hylaeiform (slender); the hairs inconspicuous without magnification; and scopa inconspicuous or absent.
The thorax is orange-brown and densely hairy, while the abdomen alternate black and white transversal stripes. The face has a whitish drawing. The third antennal segment is about as long as the three following segments together. Scopa is white, but black at the front edge. Metatarsus on the hind legs is black haired.
