abdomen brown, tarsi and joints of legs brownish red. Very 

 sparsely pilose and pubescent, the pilose hairs yellowish and very 

 short. Whole body moderately shining, clearly but not densely 

 punctured, the punctures being sharply denned but not deep ; the 

 sides of the meso- and epinotum obliquely punctate-striate. 



Head a little longer than wide, as wide behind as in front (in 

 Havilandi it is much narrower behind than in front), posterior 

 angles considerably rounded, sides and posterior margin moderately 

 convex. Clypeus strongly carinate in tbe middle, more so than in 

 Havilandi, and more acute at the apex. Mandibles smooth, with a 

 few coarse punctures, widening towards the apex, which has a 

 masticatory margin not so distinct as in Havilandi, ending in 

 a small tooth below. The eyes are smaller than in Havilandi and 

 are placed within the anterior half of the head. The scape extends 

 back beyond the occipital margin, but is not so long as in Havilandi ; 

 the 1st joint of the nagellum is very little longer than the 1st or 3rd 

 (nearly twice as long as the 1st in Havilandi). The thorax is more 

 constricted in the middle, and the pro- and mesonotum and the 

 dorsum of the epinotum are more convex. The node of the petiole 

 as long as wide behind, more convex above and not so sharply 

 truncate in front and behind, and not quite so long as in Havilandi. 

 It is also less sharply margined behind than in that species.

 $ . 8 mm. Black ; mandibles, scape, apical segment of abdomen 

 and tarsi yellowish brown ; nagellum and extreme base of scape 

 dark yellow ; apical margins of 1st and 2nd abdominal segments, 

 the whole of the 3rd and 4th segments, all the coxae and the petiole 

 piceous red. The sides of the head and the pleurae have in some 

 lights a bluish reflection. A scanty and short greyish pilosity on 

 the body and legs ; nagellum and tarsi pubescent. Impunctate. 

 Head wider in front than behind, longer by nearly one-third than it 

 is wide, sides convex, posterior margin strongly emarginate, posterior 

 angles acute. Clypeus broadly triangular, with a sharp and narrow 

 median carina ; anterior margin slightly produced and pointed in the 

 middle, finely and longitudinally striate. Frontal carinae very short 

 and narrow ; frontal sulcus narrow, deep, and extending back to 

 about the level of the anterior margin of the eyes. The latter are 

 large, convex, and situated a little in front of the middle of the sides. 

 Antennae long ; scape extends beyond the occiput by one-third of
