I/. Dull castaneous red, legs brownish yellow, abdomen brown. 

 Some specimens are brighter in colour, with the abdomen brown 

 only in the middle above, and the legs reddish yellow. Pilosity 

 very sparse ; head longitudinally striate in front, reticulate pos- 

 teriorly on the lateral lobes;* thorax transversely irregularly 

 sculptured, the metanotum striate on the basal portion ; nodes 

 of pedicel punctured, opaque ; abdomen smooth and shining. 

 Head oval, the cheeks convex, the occipital emargination narrow ; 

 mandibles proportionately rather large, punctured : clypeus slightly 

 emarginate anteriorly ; antennae slender, the scape falling short 

 of the top of the head by about one-third of its length ; 

 antennal furrow broad but shallow. Thorax anteriorly gibbous, 

 the lateral tubercles barely indicated ; the transverse mesonotal 

 furrow broad and shallow, the carina posterior to it thick, the 

 basal portion of the metanotum flat and rectangular ; metanotal 

 spines pointing slightly obliquely backwards. Pedicel : the 1st 

 node somewhat conical, but with a distinct transverse upper 

 margin and without any appendix beneath ; 2nd node short, 

 transversely fusiform, much broader than long ; abdomen oval. 



. Yellowish red, the abdomen brownish, the legs paler in 

 colour than the head and thorax ; head oval : antennae elongate, 

 the scape passing beyond the top of the head by nearly one-third 

 of its length. Thorax : the pronotum slightly bituberculate, the 

 mesonotal furrow distinct, and a wide transverse ridge behind it ; 

 metanotum elongate, bidentate. Pedicel : the 2nd node not quite 

 twice as broad as the 1st ; abdomen oval.

%. Beddish brown; the antennas, posterior portion of the 

 thorax, legs and base of abdomen paler, the last somewhat 

 yellowish, the abdomen posteriorly dsirk brown; pilosity pale 

 yellow, very abundant; the flagellum of the antenna? and the 

 tarsi of the legs minutely but densely pubescent. Head broader 

 posteriorly than in front, somewhat coarsely longitudinally striate, 

 the striae curving outwards on the lateral lobes of the head, 

 occipital emargination comparatively deep : eyes below the middle 

 line of the head ; mandibles punctured and shining ; clypeus not 

 emarginate, anteriorly depressed, smooth between the bases of the 

 antenna? ; antennal carina) produced as fine divergent stria through- 

 out the length of the scape ; antenual grooves finely rugulose 

 within. Thorax : the lateral tubercles on the pronotum strongly 

 pronounced, the transverse tnetanotal groove shallow ai
