rated from the head by a rather indistinct transverse groove, punc- 

 tured a httle more distinctly than the head ; labrum fulvous, as well 

 as the first two joints of the antennas, the rest black. Thorax 

 regularly convex, the sides much deflexed anteriorly, all the angles 

 acute, and produced into a short tooth ; surface almost smooth, a 

 shallow transverse depression extends across the disk a little behind 

 the middle, and is strongly punctured near the sides. Scutellum 

 nearly as broad as long, smooth, rufous. Elytra wider than the 

 thorax, rufous, shining, distinctly punctate-striate, the striae stronijly 

 impressed near the base and diminishing towards the apex. The 

 first stria is very short and the second curved obliquely upwards 

 towards the base ; below the basilar space is a shallow indistinct 

 fovea. The seventh and the following striae commence on the hinder 

 portion of the humeral callus, this latter being limited by the strongly 

 impressed sixth stria up to the base of the elytra. Entire underside, 

 with the exception of the abdomen, which is light-fulvous-coloured,
