(J uear II. iiirmal F.; ditfers in the coarser reticnlations on the thorax, narrower 

 head, three-pointed central thoracic armature, and parallel-sided elytra. 



$. Black, nitid ; head with the clypens rather rounded or sliglitly siunated in 

 front, terminating iu a sharp angle in front of the transverse carina ; the lateral 

 margins are concave, with another angle or point just Ijefore the eyes. Front of 

 clypens covered with a fine network of carinae, with the interspaces very finely 

 alutaceous. A raised bipointed transverse carina is on the disc of the head, very 

 coarsely reticulate behind and at the sides. 



Thorax very rough on disc and at sides, with the exception of a smooth cicatrix 

 on each side close to the lateral margins. 



Thoracic armature produced in the centre into a deflexed narrow three-pointed 

 process, the two side teeth being very slightly reflexed and the centre one strongly 

 deflexed ; from each of the two outside teeth the carina runs semicirenlarly and 

 forms another large point on each side. Truncation roughly and anterior angles 

 obsoletely pointed ; lateral margins produced into a large strong point, which 

 projects anteriorly ; the side margins of this point are slightly crennlated ; lateral 

 margins rather attenuated posteriorly. Posterior angles blunt, and the hindmargin 

 slightly sinuate and rather produced near the scutellary space. Posterior margins 

 very strongly marginate. Anterior and lateral margins fringed with long reddish 

 brown bristles. 



Elytra sliining ; interstices flat, very sparingly and finely punctured with 

 minute punctures; striae plain, but shallow. Lateral margins almost parallel; 

 margins very strongly marginate. The sutnral interstices are much raised. 



Pygidium as broad as long, emarginate, and sparingly punctured. Metatliorax 

 thickly punctured with setose punctures, with the exception of a longitudinal smooth 

 line on disc, in the centre of which is a longitudinally impressed fine line. Disc of 

 abdomen smooth; sides more or less thickly punctured. Episternum of the metatlmrax 

 very thickly punctured, and covered with fine reddish brown hairs. 



Undersides of femora smooth on disc, coarsely punctured with setose punctures 

 towards the sides. Under and upper sides of the intermediate and posterior tibiae 

 smooth on disc, with a row of large pores or jmnctuTes on the inner margins, from 

 base to apex. The punctures are unisetose. 



Anterior tibiae three-dentate on exterior margins, the apical tooth being 

 furnished with a small tooth on the disc. Two rows oi' punctures with a raised edge,
