Spine-like bristles are found on the ventral and front sides of the posterior femora, on the dorsal and posterior sides of the front tibiae and on the various sides of the posterior tibiae except on the posterior side of the hind tibiae, finally as usual some apically on the posterior femora; on the ventral side of the front femora none are found; they are for the most part yel- low, on the ventral side of the femora, especially the middle femora, and on the dorsal side of the tibiae they are generally more or less black. The spine-like bristles on the tarsi are black and yellow intermingled. Wings hyaline, slightly yellowish, especially along the veins; veins brown. Halteres yellowish. Female.
