across the base ; posternal process triangular, sharp at apex, slanting 

 slightly downwards ; anterior tibiae slender, dentate outwardly at the 

 apex only, and not sinuate above the apical tooth in the $ , bi-dentate

I have not been able to examine the maxillae of the type (<?), 

 which belongs to Mr. 0. E. Janson, who described it as a species of 

 Melinesthes. Its nearest ally is, however, Genyodonta, but it differs 

 from both in the shape of the posternal process, which is triangularly 

 aculeate instead of being long and curved upwards as in the two 

 genera above mentioned.

Male : Head, prothorax, scutellum, under side, and legs brick-red, 

 on the prothorax are two large posteriorly dilated longitudinal black 

 bands, and a somewhat indistinct black spot on each side of the 

 scutellum ; elytra elongated, straw-yellow with the suture and apical 

 margins moderately broadly dark chestnut-brown, the lateral margin 

 is also narrowly chestnut-brown, and the humeral callus, as well as 

 the edge of the base, is of the same colour ; head simple, slightly 

 impressed longitudinally on each side for nearly all the length, 

 closely punctate and glabrous ; the whole surface of the prothorax is 

 also very closely pitted, and so is the anterior part of the scutellum ; 

 elytra not distinctly costulate, but having on each side two longi- 

 tudinal dorsal impressions the sides of which simulate faint costules, 

 they are finely and moderately punctate, some of the punctures are 

 plainly seriate in the dorsal part, and the suture is raised behind ; 

 abdomen and pectus punctate, with the sides of the pectus very 

 briefly pubescent ; legs slender, very coarsely punctured, anterior 

 tibiae with one apical tooth, inner edge of anterior femora briefly 

 pubescent, that of all the tarsi somewhat briefly and not densely 

 hairy, the hind ones strongly serrate, the teeth sharper and slightly 

 hamate towards the knee. 



Female : The female differs in being of a rather larger and broader 

 form, more strongly punctured, with the club of the antennas a little 

 shorter, and the abdomen convex in the centre ; the legs are shorter 

 and stouter, the anterior tibiae broader and provided with two 

 lateral teeth, the inner side of the hind tibiae is not serrate. 



The serration of the hind tibiae in the male is not peculiar to this 

 species, it is found also, although in a lesser degree, in Genyodonta 

 var. egregia, Boh. 



Length 25-27 mm.
