4th joints as long as wide, all the remaining joints longer than wide, 

 the club 3- jointed. Thorax at its widest point hardly half the width 

 of the head. Pronotum much wider than long, the posterior half of 

 the sides sometimes fairly sharply margined. Pro-mesonotal suture 

 indicated by a wide and shallow depression. Mesonotum longer than 

 its basal width, the sides mai-ginate, the median tubercle elongate and 

 well defined. Meso-epinotal suture very deep. The dorsum of the 

 epinotum widens gradually backwards, and merges gradually into the 

 oblique declivity, which is longer than the dorsum. Epinotal spines 

 acute, strongly divergent, directed obliquely upwards, nearly two and 

 a half times longer than their basal width, as long as, or a little longer 

 than the dorsum of the epinotum. First node of petiole more or less 

 subcordate or trapezoidal, the anterior angles rounded, the dorsal face 

 shallowly concave transversely, wider than long. Peduncle of 2nd 

 joint as long as its node, the latter twice as wide as long, and divided 

 by a strong longitudinal groove into two more or less spherical and 

 convex discs. Abdomen cordate-triangular, longer than wide, the 

 basal margin straight, with moderately sharp angles. 



9 . 8'6 mm. Pilosity and pubescence as in the ^ , the colour 

 similar but darker. Head dull, finely, closely and longitudinally 

 striate, the striae curving outwards behind the ocelli, the spaces 

 between the striae very finely and sparsely punctured and somewhat 

 rugulose. The clypeus and anterior third of the head more strongly 

 striate than the rest. Mandibles strongly striate and punctured 

 between the striae. Pronotum dull and finely reticulate -punctate 

 and rugulose. Mesonotum and scutellum smooth and shining, 

 sparsely and finely punctured. Dorsum of epinotum feebly rugose 

 and dull, the sides sharply striate and reticulate-punctate between the 

 striae ; declivity smooth and shining. Sides of thorax reticulate- 

 punctate and longitudinally striate, more finely so than on the sides 

 of the epinotum. Nodes coriaceous and dull, the 2nd also 

 shallowly punctured. Abdomen smooth and moderately shining. 

 Head widest in the middle, the sides converging in front of the eyes, 

 parallel and straight behind the same, the posterior margin straight, 

 strongly convex above. Head nearly one-third wider than the thorax. 

 Mesonotum moderately convex from side to side, a little longer than 

 wide. Paraptera and scutellum together a little more than half as 

 long as the mesonotum. Dorsum of epinotum nearly four times 

 wider than long, merging by a very short curve into the vertical 

 declivity. First node of petiole similar to that of the ^ but shorter, 

 more deeply excavated in front, with the anterior angles more rounded. 

 Second node convex at the sides, one and a-half times Avider than
