Very closely allied to Ceresium, Xewm., from which it differs 

 as follows : — Femora more abruptly clavate, tibiae carinate or 

 sharply edged along the outer face, the uiiddle tibiae curved, and 

 each of the autenual joints from the fifth to the tenth with acute 

 anterior angle at the apex.

 (1873). 



Of a reddish-chestnut colour ; the head and prothorax dull ; 

 the elytra glossy, black or brownish black in the middle third of 

 their length and marked each with two yellow spots — one a little 

 before, the other just behind the middle. Antennae of c5' a little 

 longer and of 2 a little shorter than the body; faintly pubescent 

 and sparsely ciliate beneath ; third joint slightly longer than the 

 first and nearly one-third longer than the fourth : fifth to seventli 

 subequal, each very slightly longer than the third. Prothorax 

 subcylindrical, a little wider in the middle, distinctly longer than 

 broad ; closely but not very deeply punctured above and at the 

 sides, more closely and strongly punctured beneath except near the 

 front border ; disc with a short, slightly raised smooth line along 

 the middle. Elytra sparsely setose, distinctly but not very closely 

 punctured except near the apex, the punctui-es there much smaller 

 and less distiuct ; each eh' tron sharply rounded at the apex, 

 slightly depressed in front near the suture and posteriorly on 

 the middle of the disc. Metasternum, abdomen and the clavate 

 portion of the femora very glossy and almost impunctate. 



Lencjtii 8-13; breadth 2-3 miu.

Group OBRIINl. 



Eyes large, coarsely facetted, deeply emargiaate. Front coxae 

 exserted, their acetabula completely closed posteriorly, and not 

 angulated on the outer side. Acetabula of the middle coxa3 shut 

 off from the epimera. Autenna) not spined. First sternite of 

 the abdomen very long in both sexes, the second sternite of the $ 

 much longer than the third, and, in most of the genera, very 

 densely fringed \\ith hairs posteriori}-. 



Synojisis of the Genera. 



A. Front coxas very strongly exserted, sub- 



conical in form ; metathoracic episterna 

 marked each with a rather deep longi- 

 tudinal groove Obrium, p. 16-5, 



B. Front coxre less strongly exserted, sub- 



globular in form ; metathoracic episterna 

 not marked with a long-itudinal irroove.
