and thorax black, alutaceous; the clypeus, except a broad band in the middle and 

 a broad irregular line along the inner orbits reaching to near the ocelli, and the 

 mandibles, except at the apex, pale yellow, densely covered with a golden pile, and 

 with long pale hairs. Thorax densely covered with a golden pile and more or less 

 with long pale fulvous hair. Abdomen at the base pruinose, at the apex covered 

 densely with a short golden pile; the anterior portion of the three or four basal 

 segments more or less black. Wings varying from almost hyaline to having a fulvo- 

 fuscous tint. Tegulee rufous. 



The pubescence in this species is denser and of a distinctly brighter golden hue than 

 in IS. cincticornis; the antennae are entirely black; the clypeus is broadly yellow 

 laterally (while in S. cincticornis it bears only a small mark); there is no yellow 

 behind the orbits.

Clypeus moderately convex, the apex roundly projecting in the centre, the edges 

 forming a rather thick triangular tooth ; the sides obliquely truncated. Eyes touching 

 the base of the mandibles, almost parallel, the space between at the top not much 

 narrower than at the bottom. Hinder ocelli separated from the eyes by more than 

 twice the distance they are from each other. Antennae filiform, microscopically pilose. 

 Pronotum rounded in front, broadly and roundly concave behind. Median segment 

 short, rounded, the central furrow distinct. Black, the head and thorax opaque, 

 alutaceous; the sixth antennal joint entirely, the fourth broadly at the apex, and the 

 fifth at the base, yellow ; the inner orbits broadly, the outer orbits more narrowly at 

 the top and bottom, the clypeus broadly at the sides, the mandibles (except at the 

 apex), the edges of the prothorax all round (except in the middle in front), the tegulse, 

 a mark in the centre of the mesonotum, the middle of the scutellum, a mark on the
