Head opaque, coarsely alutaceous ; the top with a few long hairs ; the cheeks with 

 a thick patch of dull greyish-white pubescence ; eyes not curved at the top, straight, 

 diverging below ; the ocelli in a triangle, separated from the eyes by a much greater 

 distance than they are from each other ; there is a short, shining, straight furrow 

 above the antennae; clypeus projecting, the apex broadly rounded, shining, and 

 punctured ; occiput transverse. Antennae comparatively short, stout ; the third joint 

 distinctly longer than the fourth. Thorax opaque, alutaceous, sparsely covered with 

 black pubescence. The prothorax shorter than the head, rounded and narrowed from 

 the apex to the base ; the apex arcuate, but not forming a completely rounded curve. 

 Scutellum moderately convex, finely punctured, not narrowed towards the apex. The 

 median segment with a gradually rounded slope. Abdomen shining, subsessile, thinly 

 covered with long hairs ; longer than the head and thorax united ; the pygidium 

 rugose, thickly covered with dull fuscous hair. Tibiae serrate, the long spur of the hind

 the claws stout, placed near the base ; the fore spurs testaceous. Wings : radial cellule 

 long, narrow, lanceolate ; the second cubital cellule narrower at the top and bottom

Similar in coloration and texture of body to S. smithi ; but easily known from it by 

 the long spur of the hind tibiae reaching distinctly beyond the middle of the meta- 

 tarsus, the second cubital cellule at the top twice the length of the third, and the apex 

 of the clypeus transverse, and also by its much smaller size. Eyes diverging beneath» 

 straight. The ocelli not forming a triangle, the hinder ones separated from the eyes
