7. Octoplon calUgramvium,n.s-p. 



Magnum, elytris baud liiiearibus, latis, apicem versus ro- 

 tundato-attenuatis, piceo-nigrum, vixnitidum; thoracein- 

 sequali, tuberculato, sericeo-opaco et argenteo-tomentoso; 

 elytris basin versus inacula magna laterali subquadrata, 

 et longe post medium fascia lata postice ad suturam 

 indentata fulvig, supra passim punctatis, apice uni- 

 spinosis; femoribus inerassatis, haud clavatis, apice bi- 

 dentatis ; an tennis piceis, apicem versus pallidioribus. 



Long. 9 lin. $ . 



A large species, of much less linear figure than usual in 

 this group. The elytra much wider, with the sides rounded, 

 and tapering towards the apex ; the thorax is very un- 

 even, and projecting a little in the middle of the sides, 

 but the tubercles are not distinct or acute; the whole 

 surface is silky and sub-opaque. The elytra are thickly 

 punctured throughout, and have short erect seta? ; the 

 spots are of very large size and fulvous ; the space of 

 ground-colour left between the anterior spot and the 

 posterior fascia, forms a straight belt, owing to the fascia 

 not being advanced on the suture, and the anterior spot 

 being narrowed on the sides instead of widened.

Of shorter form than its allies, linear or cylindrical. 

 The thorax is silky and opaque, the elytra moderately 

 shining, ^vith very distinct setiferous punctures, and be-
