Gex. SCAPTOCNEMIS, n. gen. 



Buccal organs of Oniticcllus ; head with hardly any trace of genae, 

 ■clypeus emarginate, eyes showing on the upper side through a narrow^ 

 slit, antenna? eight-jointed ; prothorax plane, sub-parallel ; scutellum 

 small but distinct ; elytra sub-parallel, without epipleura, a little 

 sinuate laterally with the posterior angles rounded, striate with the 

 lines of the striae geminate ; pygidium very long, vertical and a little 

 convex in the centre ; metathorax divided from the mesosternum by 

 a raised line, very distinctly compressed in the anterior part into an 

 aculeate process fitting into a narrow, sub-ovate one proceeding from 

 the base of the prosternum ; anterior tibisB broad, straight at tip, and 

 with the four outer teeth strong, but not very long, and set close to 

 one another ; the outer one is in line with the apical part ; inter- 

 mediate and posterior tibicC long, slender ; the basal joint of hind 

 tarsi is not dilated. 



The sheaths of the penis are very different in shape from those of 

 Oniticcllus and BrciMnocliirns. The main distinctive characters are 

 the shape of the fore tibiae and the geminate striation of the elytra. 



SCAPTOCNEMIS SEGEEGIS, U. SpeC. 



Plate XXX VIII., fig. 10. 



13ronze-l)rown, head and prothorax shining, elytra duller and liaving 

 small basal rufescent patches in each interval, and one in the middle 

 of the second and third ; head with the sides of the clypeus some- 

 what diagonal, and the anterior part emarginate in tlie centre, 

 depressed and having the angles of the emargination blunt and 

 slightly recurved in the male, and very sharp in the female which 

 has also a small tooth in the centre of the emargination ; the suture 

 of the genae is quite ol)literated, the genae themselves are in a 

 line with the sides of the clypeus, and the whole surface is covered 

 with deep, closely set punctures and a thick, greyish, erect 

 pubescence ; prothorax slightly convex in the anterior part, plane 

 but a little rounded laterally behind, and very slightly attenuate 

 in front, covered with deep thickly set punctures, Ijriefly and 

 densely tomentose, the lateral fovea is very well marked, and the 

 apical margin is slightly flavescent ; elytra sub-parallel but a little 

 rounded towards the apical part, and having the humeral calkis 

 moderately developed, they are flat, truncate at apex, do not cover 

 the whole abdomen, and are finely l)tit deeply striate, each stria 

 having a raised line on each side, the intervals are plane, and have- 

 two or more series of setigerous punctures on each interval, the
