 dus, subtus squamis albidis vestitus, supra squamis fuscis et albidis 

 intermixtis depressis variegatus; antennis nigris, basi piceis ; thorace 

 paullo latiore quam longiore, profunde punctato; elytris convexis,

Hob. China. Collected by Mr. Lewis. 



Head closely and deeply punctured ; clypeus transverse, thick- 

 ened at the base; clypeus piceous; antenna? 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 subcylindrical, 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 ot larger foveo- 

 late punctures. Body beneath and legs clothed wdth narrow 

 whitish scales. 



Pachnephorus porosa, n. sp. Elongatus, subcylindricus, niger, niti- 

 dus, squamis adpressis gracillimis bifidis griseis vestitus ; pedibus 

 piceis ; antennis rufo-fulvis, extrorsum nigris ; thorace convexo, pro- 

 funde punctato ; elytris profunde regulariter punctato-striatis, inter- 

 spatiis nitidis tenuiter punctatis. Long. H lin. 



Sab. China. 



Head deeply and closely punctured ; antennae scarcely longer 

 than the head and thorax, the five outer joints black, the six basal

 sides diverging from the base to beyond the middle, thence rounded 

 and converging to the apex ; above convex, deeply impressed with 

 large round punctures. Elytra broader than the thorax, oblong-
