3rd-6tli as wide as long. Clypeal carinae sharp, well denned. Man- 

 dibles sparsely and coarsely punctured, acutely tridentate. Eyes rather 

 flat, placed in front of the middle of the head. Pro-mesonotuni 

 convex, widest in front and not much narrower than the head. Thorax 

 strongly constricted at the meso-epinotal suture, which is deep and 

 wide. The dorsum of the epinotum passes into the oblique declivity 

 by a gradual curve. Seen from the side, the dorsum of the epinotum 

 is convex lengthwise, that of the pro-mesonotum convex only in front. 

 First joint of petiole with the peduncle short, about half as long as the 

 node, which is sub-conical, longer than wide and higher than the 2nd 

 node. The 2nd node is a little wider than the 1st, wider in front than 

 behind, and as wide as long.

5' . 2T mm. Dark yellowish brown, the tarsi pale. A stouter 

 insect than the type of the race. The club of the antenna is not 

 longer than the rest of the fiagellum, hardly as long; 3rd— Sth joints 

 distinctly wider than long. The nodes of the petiole are much wider 

 than in the race, and the 1st node has the anterior face less convex, 

 and is as wide as long ; it is also less conical and more wedge-shaped. 

 The 2nd node is transversely oblong, with rather pronounced anterior 

 lateral angles, almost twice as wide as long.

£ . 15-21 mm. Brownish yellow; the thorax a little paler; legs, 

 antennae and the basal half of all the abdominal segments pale yellow. 

 Smooth and shining, with scanty and very small piligerous punctures. 

 Head about one-quarter longer than wide, the sides moderately convex, 

 posterior angles rounded, porterior margin shallowly concave. The 

 anterior margin of the ciypeus feebly excised in the middle, the clypeal 

 carinae sharp, with a longitudinal impression between them. Man- 

 dibles quadridentate, shining, sparsely and feebly punctured. Eyes 

 large, placed a little in front of the middle of the head. The scape 

 does not extend bach as far as the posterior margin of the head. 3rd- 

 7th joints of the fiagellum as wide as, or a little wider than, long ; the 

 1st joint as long as the three following taken together; the club as
