 projecting, the face only slightly retreating; no ocelli ; antennae almost 

 as long as the face, the first joint twice as long as broad, the second one 

 and one-half times as long as the first, the third tapering slightly lo 

 the apex, which is broadly rounded, the upper edge concave, the lower 

 convex, one and one-fourth times as loDg as the second; arista bare,

 extends across it, the side of the scutellura and of the metanotum, the 

 two vittae connected with each other by a black fascia at the base of 

 the scutellum, aud on the outer side each throws off a spur which
