dull. Abdomen microscopically rugulose and dull, fairly closely and 

 finely punctured. Head more deeply marginate behind than in the 

 type-species, the scapes as long as in the type-species or very little 

 shorter. Thorax resembling that of the type-species, but the pronotum 

 is subvertical in front, the junction of the vertical and horizontal 

 faces rounded ; the declivity of the mesonotum is shorter, less oblique, 

 fairly distinctly marginate at the sides, the margins ending in front in 

 a subdentate prominence. The dorsum of the epinotum is relatively 

 longer and flatter than in the type, and also less widened towards the 

 apex ; it is as long in the middle as it is wide at the base. First 

 segment of petiole as wide as long. Node of 2nd segment a little 

 narrower in front than behind, one-third wider than long. Otherwise 

 like the type-species.

Apart from the shape of the dorsum of the epinotum and the deeper 

 occipital emargination, this form differs but little except in size from 

 the type of the species. It has no relationship whatever to gabonensis,

Emery, in which species the 2nd node is entire, without a median 

 groove or even a posterior emargiuation. Moi'eover, in gabonensis the 

 spines are nearly as long as the dorsum of the epinotum, and the sculp- 

 ture is of a different character.

^ . 3 "6-5 mm. Black, tarsi brown, mandibles dull ferruginous, 

 antennae reddish-brown, the scapes and flageHuni darker towards the 

 apex. Sculpture similar to that of the type-species but stronger. 

 The striae on the head become increasingly oblique posteriorly and 

 near the posterior angles are directed outwards, or almost transverse. 

 The smooth median area is wider (covering about one-third of the 

 diameter of the vertex) and more strongly punctured. The dorsum of 

 the epinotum is very sharply reticulate, with a few oblique and fine 

 rugae near the base. The sides of the pro- and epithorax more 

 coarsely sculptured than in the type of the species. First abdominal 

 segment very finely punctured. The frontal area and sulcus more 

 clearly defined than in the type of the species. The scape extends back
