20 Mr. F. P. Pascoe's Descriptions of New Genera 



Ceramhyx versutus. 

 C. brunneus ; capite prothoraceque fiiscis, hoc irregulariter 

 corrugate utrinque fortiter spinoso ; elytris apice bidenta- 

 tis ; antennis pedibusque rufis. 

 Ceylon. 



Reddish brown ; head and prothorax dark brown, the latter 

 irregularly corrugated with a strong spine on each side ; elytra 

 with two small teeth at the apex of each ; legs and antennas rufous 

 brown ; body beneath with a sparse silvery pubescence. 

 Length 12 lines. 



Nearly allied to C. consochis, but the prothorax is transverse, 

 irregularly and more finely corrugated, elytra larger and less 

 strongly toothed at the apex, &c. C. humeralis, White, is also a 

 closely-allied species. 



Ceramhyx consocius. 

 C. brunneus; prothorace angustato sub-transverse-corrugato, 

 utrinque obtuse -dentato, elytris apice bispinosis ; corpore 

 subtus sericeo-pubescente ; antennis pedibusque rufis. 

 Ceylon. 



Reddish brown; prothorax narrow, deeply and nearly trans- 

 versely corrugated, with an obtuse tooth on each side at about the 

 middle ; elytra widest at the base, the apex of each with two 

 strong spines ; antennae and legs rufous brown ; under surface 

 with a sparse silvery pubescence. 

 Length 13 lines, 



Ceramhyx macilentus. 

 C. attenuatus, obscure piceo-fuscus pube grisescente indutus ; 

 prothorace mutico, corrugato ; elytris obsolete punctatis, 

 apice bispinosis, spina exteriori divaricata. ; antennis no- 

 dulosis. 

 Ceylon. 



Attenuate, dull pitchy brown, with a slight greyish pubescence ; 

 prothorax narrowed in front, unarmed and rather finely corrugated ; 

 elytra obsoletely punctate, tapering from the base, with a broad 

 slightly elevated somewhat oblique ridge, the apex bispinous, the 

 outer spine strongly divaricate; antennas nearly tuice the length 

 of the body, the four or five basal joints nodulose ; legs mode- 

 rate. 



Length 13 lines. 



A very distinct species of which I have only seen the male.
