The thorax is fairly strongly constricted laterally at the meso-epinotal 

 suture. Pro-mesonotum about one-third longer than wide, the sides 

 convex. Dorsum of the epinotum shorter than the oblique declivity, 

 into which it merges by a gentle curve ; sides of the declivity distinctly 

 margined, the raised margins extending indistinctly almost to the 

 base of the dorsum. First joint of petiole very shortly pedunculate, 

 the node wider than long, ovate, convex above. Second node as 

 wide, or nearly as wide, as the 1st, of similar shape, but a trifle 

 longer. Abdomen ovate, all the segment wider than long. 



$ . 24 mm. Length of anterior wing, 23'5 mm. Head, thorax 

 and petiole black ; abdomen varying from dark red to reddish brown. 

 Mandibles and legs dark brown ; tarsi and antennae reddish brown. 

 Thorax shining, the rest of the body nitidulous. Head, thorax and 

 nodes with a sparse, yellowish and adpressed pubescence (coarse and 

 almost pilose) ; abdomen sparsely and finely pubescent. Clypeus 

 with a few fairly long pilose hairs. Antennae densely pubescent. 

 Tibiae and tarsi densely clothed with long and almost bristly hairs, 

 which form dense tufts at the apical margins of the tibia and of the 

 first four tarsal joints. Head closely and very coarsely punctured, 

 each puncture with a piligerous prominence in its centre ; the space 

 between the punctures rugose. Mandibles longitudinally striate and 

 strongly punctured between the striae. Mesonotum and petiole 

 sparsely punctured, the punctures similar to those on the head, but 

 smaller and shallower. Sides of thorax closely striate and more or 

 less punctured. Epinotum dull, very closely and minutely punctured, 

 the sides with a few strong striae ; the dorsum with a few large and 

 deep punctures ; the declivity with its upper margin more or less 

 rugoso-striate. Abdomen microscopically alutaceous, and also sparsely 

 punctured, the punctures strong, but not so large or deep as those of 

 the mesonotum. Head, including the mandibles, triangular, much 

 wider behind than in front, the posterior angles widely rounded. 

 Clypeus short, the median area raised, convex transversely, truncate or 

 deeply impressed in front, and with a small tubercle behind the 

 middle of the anterior margin. Frontal carinae short. Mandibles 

 quadridentate ; the teeth somewhat obtuse. Antennae 10-jointed, the 

 scape extending back as far as the posterior ocelli ; the 1st joint of 

 the flagellum a little longer than wide, the 2nd-6th joints wider 

 than long. Eyes fairly large, oblique and ovate. Ocelli not large. 

 Thorax much wider and higher than the head. Only the shoulders of 

 the pronotum are visible from above ; mesonotum very high and 

 convex in front, hiding the pronotum ; parapsidal sutures distinct. 

 The scutellum semicircular, somewhat pointed posteriorly, and sepa-
