$. Black; scape of antennae, tegulae, legs except coxae, and the first 3 segments of abdomen red; wing 

 yellow at base and broadly along the costa, otherwise fuscous with purplish iridescence, the veins included in 

 the yellow portion, reddish, those in the fuscous portion dark; head with strong confluent punctures. posteriorly 

 deeply incurved, the occiput margined; face between the antennae prominently convex, and meeting the clypeus 

 so as to appear continous with it; the clypeus slopes from its middle to apex, which is broadly truncate, the 

 sloping portion smooth (or nearly so) and shining, otherwise the clypeus is corsely punctured ; mandibles striato- 

 punctate, furrowed from middle to apex, slightly broader at apex than at base, narrowed medially, bearing a 

 tooth within and 4 at apex; dorsulum with strong punctures, which, when the insert is held in certain positions, 

 give the dorsulum a transversely striated appearance ; punctures of the scutellum a little closer, those of the meso- 

 pleurae more distinct; legs robust, the hind tibiae much thickened toward apex; abdomen sparsely punctured, 

 the apical margins of dorsals 1 — 4 transversely depressed at apex, at which place the punctures are closer; front, 

 base of clypeus, a fringe on labrum, thorax above, on center of mesopleurae and base of middle segment, and 

 a fringe at apex of dorsals 1 — 3, ochraceous; beneath the wings, extending to sides of middle segments a spot 

 on each side of the first 3 or 4 dorsals and the ventral scopa, whitish on the cheeks and thorax beneath the 

 pubescence is pale; legs and last 2 or 3 dorsals covered with a short ochraceous pubescence, that on the tarsi 

 the longer. L. 13 — 16 mm. 



2 ?, the larger specimen is marked „from nest is insert tin, November 28, 1894" and is from near Laga, 

 the red color on abdomen in the larger specimens is more distributed than in the smaller.

„$. Black, abdomen covered with ferruginous pubescence, apex of thorax and base of abdomen in both 

 sexes with longer whitish hair, hair on the head and thorax in ? black, scopa pale fulvous; wings fuscous- 

 violaceous, nervures black; hair on the legs $ blackish, on inner side of tarsi rufous, J long, thick and white, 

 rufous on the inner side of tarsi; mandibles bidentate. L. 14 mm. 



Mandibles at the base closely rugose, middle with longish punctures and with stout Striae; the apical 



tooth bluntly rounded; the subapical much shorter, bluntly rounded. Clypeus closely rugose; the apex in the 



centre slightly broadly incised, the sides broadly rounded. Front with a distinct furrow down the middle. 



Thorax closely, strongly punctured; the hair on the top short, close and black; on the pleurae and breast longer, 



denser and soot-coloured. The female of imitata, as named by Smith for me, has the wings much lighter 



coloured, the mandibles behind the apical two teeth broadly bisinuate, which is not the case with comhala; the 



hair on the face and clypeus white and thick, not black and rather sparse; the hair on the thorax is lighter 



coloured, and the ventral scopa is paler at the base. I am somewhat doubtful about Mr. Smith's identification
