densest on the apical margins of the abdominal segments. Head 

 longer than wide, convex above, moderately emarginate behind, 

 posterior angles sub-acute, sides convex. Eyes rather large, situated 

 a little in front of the middle of the sides of the head. Clypeus 

 narrow and sloping inwards. Frontal carinae very narrow and 

 raised, continued in front (along the margin of the clypeus), round to 

 the antennal socket ; above, the carinae are angularly bent near their 

 middle, then converge and end abruptly. There is a semicircular 

 carina on each cheek, externally. 



Tbe scape, strongly incrassate towards the apex, hardly reaches to 

 the posterior margin of the eyes : 1st to 10th joints of the flagellum 

 wider than long, apical joint much longer than wide, as long as the 

 6th-10th joints taken together. 



Thorax slightly narrowed in the middle, submarginate anteriorly, 

 with pronounced anterior lateral angles, all the sutures obliterated, 

 the sides seen from above moderately convex ; the tborax is as long 

 as, or only very little longer than the petiole and 1st abdominal 

 segment taken together. The declivity of the epinotum vertical and 

 bounded by a feebly raised margin. Petiole wider than long, slightly 

 narrower in front than behind, convex above, moderately so at the 

 sides, vertically truncate in front and behind. 



First abdominal segment wider behind than in front, one-fifth 

 longer than the petiole, convex above and at the sides ; the constric- 

 tion between the 1st and 2nd abdominal segments deep and strong ; 

 2nd segment one-quarter longer than the 1st, globose, and with the 

 sides very convex. The ventral lamella of the petiole is produced 

 anteriorly and is sharply truncate.

£ . 4 mm. This differs from the type in its slightly larger size, and 

 in having the petiole broader by one-quarter than it is long, the 1st 

 abdominal segment is also a little broader. The puncturation is also 

 slightly closer and larger.

 body, including the tibiae, femora, and antennae covered with long,
