five. Scutellum conical, its lateral margin posteriorly acute, the 
edge preceded by a prominent sulcus, the sclerite terminating 
caudad in a short bidentate plate, each tooth nearly a lobe, obtuse 
and broad for a tooth. Metathorax about as in minutus as also 
the ciliation of the wings and the proportionate lengths of the 
veins, only the postmarginal vein slightly longer. The marginal 
cilia of both wings are alike, however. Longitudinal striae margin 
the eyes in the cephalic aspect; ventrad of the insertion of the 
antennae, the face is punctured, the punctures shallow. Pube- 
scence white, nearly as in minutus. 
Antennae as in the preceding species. Pedicel not half the 
size of the proximal funicle joint which is subquadrate; next 
two joints subequal, a fifth or fourth shorter, wider than long; 
remaining joints gradually shortening distad, the last shortest; 
distal club joint shortest of the club, the two others subequal 
and wider than long though not very much so.
