Head ver>' larpc, extonditiR imok over tia- tlmrax to the rnestx'pinotal (tm- 

 striotion. suhnut annular, a lit tit' lon^tT than l)road. with slraijtht, paralN'l 

 sides in fn)nt and roundi-*.! ixisterior corners, or lol)os, s«'parat<'<l hy an anirTular 

 occipital inci.-^ion continuous with a dcvp occijjital aiul frontal prcHive, running' 

 fonvard to the clyixnis. In profile the dorsal svirfao- of the head is convex 

 and rounded, but distinctly depressed in the middle just in fnmt of the occi- 

 pital lK>rder. Eyes .small, elongate ellii)tica!, rather convex, at the anterior 

 fourth of the sides. Clypeus, mandihies, and antennal scrobes shap?d much 

 as in dyak, but the frontal carinae which lx>rder them much more diverning 

 behind and the frontal area obsolete, .\ntennae also very similar, but joints 

 2 and 3 more transverse and joints 4-S as Ioiir as broad. Thorax short, the 

 epinotal spines ver>' lonp, stout at the ba.«e, tajx'ring and pointe<l at the tips, 

 strongly cur\'ed backward aiid downward and somewhat outward. Petiole 

 fully twice as lonp as bmad, its anteropisteriorly compressed nwle narrowed 

 above, without spines, but with it* rather sharp, transverse margin angularly ex- 

 cised. Postpetiole regularly rectangular, broader than long, broader than the 

 petiole, rather flat alx)ve. Ga.ster about \ as large as the head, excluding the 

 mandibles, nearly circular, with rather straight anterior border. Femora 

 thickened in the middle, tibiae clavate. 



Shining; mandibles and clypeus smooth, the former si)arsely and finely 

 punctate, the latter without rugosities along its anterior border. Head 

 covered rather unilonuly with sj)arse, punctate foveolae, the triangular space 

 between the two limbs of each scrol>e very coarsely reticulate-rugose, the space 

 between the frontal carinae finely, but not uniformly, longitudinally striate, 

 the scrobes transversely striolate. Thorax and iK)stpetiole ver\- coarsely 

 reticulate-rugose, epinotal declivity between the spines, the petiole and gaster 

 ver>- smooth and shining. 



Pilosity much as in dyak, but the hairs longer and more delicate, though 

 blunt, and somewhat more numerous on the head, forming an even row along 

 the anterior border of the antenna! scapes and more numerous on the extensor 

 than on the flexor surfaces of the legs. 



Brownish ferruginous; mandibles, antennae, and legs deep red; j^etiolar \\rx\c. 

 postpetiole, and gaster black.
