yellowish-brown. The upper surface of the head bears moderately 

 long, blunt, pilose hairs ; on the under surface of the head and 

 abdomen and on the coxae these hairs are more pointed, and the legs 

 have only a short and decumbent pubescence. Mandibles sparsely 

 punctured and shallowly striate, more strongly and closely striate on 

 the basal third. Head moderately shining, rectangular, longer than 

 wide, the angles rounded, the posterior margin slightly concave. 

 Clypeus with a strong median carina and some longitudinal lines 

 laterally. The f rons, and vertex as far as the hind margin, with widely 

 spaced longitudinal striae, between which are some weaker longitudinal 

 rugae and a somewhat indistinct reticulation. Cheeks and sides of 

 the head coarsely and longitudinally rugose and reticulate. The well- 

 defined and long scrobe is finely reticulate, and, like the frontal carina 

 above it, reaches nearly to the posterior margin of the head. The 

 scapes extend to the posterior margin ; 2nd-6th joints of theflagellum 

 about equal in length and width, 7th and 8th distinctly longer than 

 wide, the 1st and 2nd joint of the club quite one and a half times 

 longer than wide, the last joint about three times longer than wide. 



" Thorax not short ; coarsely reticulate, and more or less coarsely and 

 longitudinally rugose, the sides behind the pronotum reticulate- 

 punctate, and with fewer longitudinal rugae, the epinotum between the 

 spines finely but not sharply reticulate, and with or without a few fine, 

 indistinct, and transverse rugae. The thorax above is constricted, and 

 the profile, from the hind margin of the pronotum as far as the 

 epinotal spines is fairly straight, only slightly depressed in front of 

 the epinotum ; the epinotal spines are not long, about as long as the 

 interval between their bases, and are directed steeply upwards, not 

 strongly divergent; the episternal teeth form equal-sided triangles. 

 Petiole coarsely reticulate, 1st node slightly wider than long, and 

 somewhat higher than the 2nd node, the anterior face vertical and 

 convex transversely, separated by a semi-circular margin from the 

 upper surface and the sides ; the upper face merges gradually into the 

 posterior ; 2nd node somewhat wider than the 1st, transversely oval. 

 Abdomen smooth and shining."
