Seen from above, the node is trapezoidal, wider behind than in front, 

 about one-third wider than long. Second node a little wider than the 

 1st, distinctly wider than long ; the anterior margin seen from above, 

 is convex, narrower behind than in front. Abdomen ovate, slightly 

 truncate at the base, the basal angles widely rounded. Femora only 

 slightly swollen.

^ . 2 2-2 - 4 mm. Brown ; the head and abdomen dark brown, 

 egs, antennae, and mandibles ochreous. Closely allied to mossame- 

 densis, but smaller and more slender, and differing from it in the 

 following characters : 



The sculpture is finer and closer ; on the thorax the larger reticula- 

 tions are almost absent, the pronotum smooth and shining, or only 

 reticulate-punctate at its margins. The frontal carinae are more 

 distinct and form shallow demiscrobes, the floor of which is slightly 

 shining and less strongly reticulate than the rest of the head. The 

 pronotal shoulders are more rounded, and the profile of the dorsum 

 of the thorax is not depressed between the nieso- and epinotum 

 The epinotal teeth are much smaller, much shorter than their basal 

 width, being hardly more than wide angles, also shorter and smaller 

 than the episternal teeth. The thorax is not marginate above. The 

 dorsal surface of the 1st node is as long as wide (wider than long in 

 mossamedensis) , submarginate in front, the anterior margin not so 

 convex as in mossamedensis. 



? . 3 - 3-3'5 mm. Very dark brown, almost black, the extreme 

 apices of the abdominal segments testaceous ; legs, antennae, and 

 mandibles ochreous. Head narrower in front than behind and, 

 excluding the mandibles, one-fifth longer than wide. Mesonotum 

 and scutellum finely, closely, and longitudinally striate, sides of 

 thorax rugulose. Mesonotum rather flat, with the scutellum very 

 little higher than the dorsum of the epinotum. Epinotal teeth acute, 

 subvertical, a little longer than their basal width, longer and larger 

 than the episternal teeth. Second node relatively wider than in the 

 $ , about twice as wide as long. Otherwise like the ^ .
