138 NORTHERN ZOOLOGY. 



DESCRIPTION. 



Body obovate, black, covered more or less with long yellowish hairs. Head punctured ; nose 

 reflexed, emarginate; stalk of the antennae testaceous, scape and knob black; palpi dusky: protho- 

 rax punctured, less hairy in the disk, not channelled : elytra black, very short, depressed next the 

 suture with an intermediate ridge ; at the base is a large pale-yellow spot common to both elytra, 

 from which run a pair of narrow, white, mealy bands, which nearly reach the external margin, and a 

 white mealy stripe adjoining the suture also runs from the same spot to the apex of the elytrum : 

 the podex is covered with long yellowish hairs, so thick on the sides as almost to conceal the oblong 

 white mealy spot common to the subgenus : legs black. 



N. B. In the specimen taken in the Expedition, the white mealy stripe next the suture appears 

 to have been rubbed off and is replaced by a continuation of the pale spot. 



There appear to be many species of this subgenus. That now described Dr. Harris thought 

 might be a variety of T. piger F, but it differs from that species not only in painting, but also in 

 sculpture and cloathing ; for it has no channel on the prothorax, which is very conspicuous in the 

 former insect ; the podex is covered with very long and dense hairs so as to conceal the lateral mealy 

 spots, while in T. piger the hairs are very short and the mealy spots very conspicuous. The head 

 and thorax of the latter are bronzed, the whole of the antennae testaceous, the elytra, podex, and 

 legs 9 also, are testaceous, the former with a pair of abbreviated lateral bands, but no sutural stripe. 

 So that T. assimilis is clearly distinct. 



(188) 3. * Trichius (Trichinus) rotundicollis. Round-necked Trichinus. 



T. T. ( rotundicollis) nigtr, pallido villosus ; prothorace suborbiculato, canaliculate ; elytris fasciis duabus intus testaceis, extus, 



lineolaque ante scutellum, pollinoso-albidis. 

 Round-necked T. Trichinus, black with pale hair: prothorax suborbicular, channelled ; elytra with two bands internally 



testaceous, externally, as well as a line before the scutellum, mealy-white. 



Length of the body 5A lines. 



Taken in Nova Scotia by Capt. Hall. 



9 Olivier's Cetonia pigra (Ent. i, C, C4, 78, t. vii, /. 54) is described as having the legs black-bronzed. If this is not an 

 error it must be a distinct species.
