16 Mr. H. E. AuJrewes on Oriental Carabidpe. 



behind than in front, border narrow in front, thicker behind, 

 hind angles obtuse, but not much rounded ; median line very- 

 fine, basal fovea? short but fairly deep, curving outwards at 

 both extremities, surface moderately punctate, closely near 

 hind angles, disk almost smooth (except along median line), 

 evidently pubescent. 



Elytra (8*0 mm. long) ovate, subconvex, border rounded 

 at shoulders, sinuate near apex, punctate-striate, intervals 

 flat, surface rather finely aciculate-punctate, more closely at 

 sides, with a fairly long golden-yellow pubescence. 



Underside moderately shiny, closely punctate and pubes- 

 cent, ventral surface very closely and finely, presternum 

 punctate between coxae, process with indications of a border 

 only, metepisterna elongate, closely punctate, metasternum 

 with some coarse punctures as well. Upper surface of tarsi 

 minutely punctate, practically glabrous. Dilated joints of 

 front tarsi (<£) rather elongate. 



According to Chaudoir's table the species would go with 

 C. tristis, Sch.aU., and 0. nigricornis, F., but it is more 

 closely allied to C. submarginatus, Chaud. Head a little 

 wider than in the last-named species, prothorax less con- 

 tracted behind, sides and especially hind angles much less 

 rounded, less closely punctate, elytra more finely punctate, 

 prosternal process practically unbordered. I think probably 

 Chaudoir attached too much importance to the border on the 

 prosternal process in this genus, as he did also in Codes (see 

 Bates, Ann. Mas. Civ. Gen. 1892, p. 323).

Cidccnius uninotatus, $ ? . 



Length 10-11 mm. ; width 3*75-4'0 mm. 



Blue-black; head metallic green or blue-green, border and 

 epipleurse of prothorax reddish ; legs, palpi, labium, joints 1 

 and 2 of antennas, and a common spot near apex of elytra 

 testaceous. 



Head (2'0 mm. wide) convex, minutely punctate, smoother 

 on vertex, frontal fovea? nearly obsolete, joints 1 and 2 of 

 antennae sparsely pilose, 3 more closely so and a little longer 

 than 4, palpi slender, obliquely truncate at apex, labium 

 truncate. 



Prothorax transverse (2 , 75x2 , 25 mm.), flat, widest at 

 middle, equally contracted and slightly emarginate at both 

 extremities, very finely bordered at sides, strongly and evenly
