very shining. Head and pronotum closely and finely - reticulate- 

 punctate, the rest of the thorax, the petiole and abdomen trans- 

 versely rugulose. Cheeks and pronotum sparsely and very shallowly 

 punctured, the punctures pubescent. Pubescence decumbent, greyish, 

 very sparse and evenly distributed, somewhat longer and more 

 abundant on the antennae and tibiae. Pilosity dirty white, fairly 

 long, sparse everywhere, particularly on the thorax. Head strongly 

 convex above, a little longer than wide, not much wider behind than 

 in front, the sides feebly convex, the posterior margin shallowly 

 concave, the posterior angles narrowly rounded. Mandibles strongly 

 punctured, 7-dentate. Clypeus subcarinate, the anterior margin 

 straight, hardly lobed. The frontal carinae as wide apart as long. 

 Eyes nearly flat, their greater part lying behind the middle. Scapes 

 short, not reaching- the posterior margin of the head. Pronotum 

 twice as wide as long, its dorsum very feebly convex, with much 

 rounded but fairly distinct shoulders. Mesonotum somewhat rapidly 

 narrowed posteriorly, nearly as long as wide in front. Metanotum 

 very small. Seen from the side, the profile of the thorax is convex 

 and rises from the front to the base of the mesonotum, thence descend- 

 ing more steeply to the brow of the declivity. Dorsum of epinotum 

 almost straight, a trifle longer than the subvertical declivity which it 

 joins in a distinct angle, slightly rounded at the extreme apex. The 

 declivity is slightly concave vertically. Scale of petiole thick, higher 

 than long, its anterior face convex, with a distinct dorsal face which 

 is two and one-third times wider than long, the posterior face flat. 

 Tibiae cylindrical, not setose below. 



$ minor, 3-8-4 mm. Black ; basal half of the scapes, the flagellum, 

 mandibles and tarsi reddish or brownish ochreous. Sculpture like 

 that of the 2J. but finer, the head shining, the thorax as shining as 

 the abdomen. Pilosity on the abdomen longer than in the 2L. Head 

 not quite one-fourth longer than wide, slightly narrowed in front, the 

 posterior margin and the sides behind the eyes semicircular, the sides 

 in front of the eyes rectilinear and convergent anteriorly. Eyes 

 moderately convex, occupying the third 4th of the sides. The 

 scapes extend beyond the hind margin by one-third of their length. 

 Clypeus sharpty carinate, not lobed, the anterior margin nearly 

 straight. The disc of the pronotum is almost flat, with the shoulders 

 submarginate. Meso-epinotal suture very feeble, obsolete in the 

 middle. The dorsum of the epinotum feebly concave longitudinally, 

 twice as long as the subhorizontal declivity. Scale of petiole nodiform, 

 the anterior and posterior faces vertical, the dorsal face large
