long as the rest of the flagellum. Thorax moderately constricted. 

 Dorsum of epinotum not quite half as long as the pro-mesonotum. 

 The latter and the epinotum are feebly convex lengthwise, the whole 

 thorax sloping steeply from front to back. The dorsum of the epi- 

 notum twice as long as the declivity, the one merging into the other 

 by a gentle curve. First node of petiole wedge-shaped, rounded above, 

 higher than the 2nd, about as wide as long and twice as long as its 

 peduncle. Second node sub-quadrate ; narrower behind than in front ; 

 hardly wider than the 1st. 



" $. 4 - 7 mm. Head quadrate ; wider than the thorax. The scape 

 extends back just as far as the posterior margin of the head. Meso- 

 notum narrow ; the dorsal profile straight. Epinotum almost cuboid, 

 with two longitudinal swellings. Head, thorax and petiole very 

 slightly shining, almost dull ; partly reticulate-puuctate ; partly longi- 

 tudinally striate, especially the front of the vertex. Black; mandibles, 

 antennae and legs reddish (deiilated). Otherwise like the ^ •"

^ • 16-T9 mm. Reddish or amber yellow, the sides of the thorax 

 and the nodes a little darker. Very smooth and shining ; almost im- 

 punctate. A few long and thin pilose hairs on the thorax, nodes and 

 abdomen, the hairs oblique and flavous. Head one-fifth longer than 

 wide, the sides feebly convex, the posterior angles strongly rounded, 

 the posterior margin shallowly concave. Eyes placed a little in front 

 of the middle of the sides of the head. The scape extends back almost 

 to the posterior margin. The club is not thick; the 1st joint of the 

 flagellum is nearly as long as the five following joints taken together ; 

 the 2nd joint is a little longer than wide; the 3rd-8th wider than 

 long. The clypeal carinae are well defined; the anterior margin of 

 the median area almost straight or very feebly concave. Mandibles 

 smooth, punctured, quaclridentate ; the apical tooth acute, the inner- 

 most indistinct. Thorax rather strongly constricted at the meso- 

 epinotal suture. Dorsal profile of both pro-mesonotum and epinotum 

 convex. Epinotum a little more than two-thirds the length of the 

 pro-mesonotum, its dorsum longer than the declivity, which is oblique. 

 The 1st node of the petiole is more squamiform than usual for the 

 genus, and is not much thicker at the base than it is above. It is 

 about one and a half times as high as long, and one and a half times
