This appears to be a common species in Malacca. It is represented 

 in Europe by jE. scabricorne, and in North China by &. sinicum, 

 both very nearly allied. Mr. Bowring finds it at Hong Kong, and 

 Mr. Wallace at Macassar, as well as in Bouru and Amboyna.

 genubus concoloribus. 



Elongate, pale ferruginous, glabrous, tips of the mandibles black ; 

 head and prothorax opake, covered with numerous small granules ; 

 scutellum subscutiform, rounded behind ; elytra parallel, closely 

 punctured, each puncture with a small whitish scale at the base, 

 with three costse, exclusive of the raised suture and the submarginal 

 raised line externally, the inner costa shortest, but not connected with 

 the intermediate, nor the latter with the outer costa, apices mucronate 

 at the suture ; body beneath with a short greyish pile ; legs finely 

 punctured, glabrous ; antennae glabrous, half as long as the body, the
