Hob. China. Collected by Mr. Lewis. 



Head closely and deeply punctured ; clypeus transverse, thick- 

 ened at the base; clypeus piceous; antennae rather longer than 

 the head and thorax, the basal and the five upper joints black, the 

 rest piceous. Thorax rather broader than long ; sides diverging 

 from the base to beyond the middle, thence rounded and conver- 

 ging to the apex ; upper surface sub cylindrical, convex on the disk, 

 deeply punctured, clothed with oblong, bifid, fuscous and white 

 scales, which form irregular patches on the surface. Elytra broadly 

 oblong-ovate, excavated at the base near the suture, and again 

 below the basilar space, deeply punctate-striate, the interspaces 

 nitidous, slightly convex towards the apex and on the outer 

 side ; surface clothed with white and fuscous scales similar to 

 those on the thorax, the former arranged in irregular patches ; at 

 the base, near the scutellura, the striae are confused, that portion 

 of the surface being impressed with a number of larger foveo- 

 late punctures. Body beneath and legs clothed with narrow 

 whitish scales.
