tuclinal middle line. Elytra as broad at the base as the pro- 

 thorax; the humeral angles are rounded. Corresponding to the 

 basal depressions of the pronotum, the opposite elytral areas at 

 the base are also depressed. The surface is punctate, covered 

 with brown pubescence. Each elytron has four feeble costte, 

 the two inner ones — i. e., those nearer the suture — being more 

 prominent than the outer ones ; the two inner ones commence 

 at the base and terminate before reaching the apex ; the third, 

 commencing posterior to the humerus, terminates about the

just beyond the middle. Of the four costse the third is the 

 feeblest ; to a certain extent they converge towards the apex. 

 Scutellum triangular, light brown, pubescent, impunctate, sub- 

 nitid. Underside brown, but lighter than the colour of the 

 upperside ; the abdominal segments have a slight suffusion of 

 black. The surface is sparsely covered with fine brown hairs, 

 their roots give the surface an appearance of being finely punc- 

 tate. The abdominal segments are at a lower level than the 

 metathoracic segment ; each is convex in the middle and de- 

 pressed at the sides, these lateral depressions forming an oblique 

 line on either side. The underside of the femora and tibiae is 

 not sulcate.
