Very closely allied to the C. nigrita; black, covered with a 

 yellow, silky, very dense pubescence. The head is very finely 

 shagreened and scarcely pubescent. The labial as well as the 

 maxillary palpi are of a clear ferruginous colour. The antenna? 

 are ferruginous, with the four last joints of a deep brown. The 

 thorax is very finely shagreened, much more pubescent than the 

 head ; it is very slightly convex, rounded on the sides, with the 

 posterior angles projecting and pretty strongly acuminate. The 

 scutellum is very finely granulated and scarcely pubescent. The 

 elytra are a little more strongly granulated than the head and 

 thorax, and are very pubescent. All the body below is granulated, 

 scarcely pubescent, and of the same colour as above. The legs 

 are ferruginous, very lightly pubescent, with the thighs blackish. 



Found by M. Lucas in Algeria under stones in the month 

 of June. He mentions Oran and the Bondjarea as localities 

 where he took it, and he observes that it is very agile. 



The above description is reproduced from that of M. Lucas. 

 I have seen specimens in his possession, but not having had 

 an opportunity of comparing them with the specimens in my 

 own cabinet, I am not able to pronounce positively upon them. 

 The same remark applies to the other two species from Algeria 

 described by him (marginicollis and rufipennis).

" Oblongo-ovatus, convexus, posterius valde angustatus pallide 

 rufo-ferrugineus ; capite, thoracis dorso, pectore abdomineque

 thorace antrorsum angustato, lateribus deflexo, angulis posticis 

 productis acutis; elytris stria tantum suturali exarata*."

Menetries says that this species somewhat resembles his 

 C. lateritius (already described (No. 5) in the first group), but 

 that it is much more convex and narrower behind, with the pos- 

 terior angles of the thorax pointed and prolonged backwards ; he 

 adds that moreover it has no perceptible strise on the elytra, ex- 

 cept one along the suture, but that it is particularly the colour 

 which distinguishes it at the first glance. 



I have not seen this species, but the above description, parti- 

 cularly the portion which I have printed in italics, would seem
