220 ON THE CARENIDES (PAM. CARABID^E), 



A very distinct species, evidently not closely allied to any of 

 those previously described. Its general appearance is that of a 

 Eiitotna, but it presents characters intermediate between Eutoma 

 and Conopterum; indeed, but for the narrow inflexed margins of 

 the elytra I should have placed it in Conopterum; the inflexed 

 margins of the elytra are similar to those of Car^num quadri- 

 pivnctatum, Macl., and the margins do not form a thick lateral 

 bead as in Eutoma. A well marked foveiform impression is 

 noticeable on the upturned margin of the apical ventral segment 

 at each side of the apex, just above the posterior lateral setigerous 

 punctures of the segment; these fovete are also found in the 

 species of the genera Conopterum, and Careniiiium, but I have 

 not seen them in any species of the genus Carenum. 



Trichocarenum cylindricum, n.sp. 



Elongate, cylindrical, laevigate; head large, suborbital channels 

 very wide and not divided by a ridge in middle; prothorax of 

 equal length and breadth, anterior an^^des lightly advanced; elytra 

 oval, the border slightly upturned at shoulders, a submarginal 

 row of six or seven distant punctures on each elytron, inflexed 

 margin narrow behind first ventral segment ; anterior tibiue 

 bidentate, intermediate tibisp with a very weak external spur at 

 apex. Black, shining. 



Head large, convex (4 x 5 mm.); frontal sulci deep, diverging 

 backwards from clypeus in a sinuous course, their anterior out- 

 turned part hardly mai'ked; clypeus with median part roundly 

 and deeply declivous, subtruncate (obsoletely trisinuate), inter- 

 mediate angles wide, obtuse ; pi'eocular sulcus very lightly 

 marked ; eyes depressed, deeply set in orbits ; postocular pro- 

 minence two-thirds the size of and projecting slightly beyond eye; 

 two supraorbital . punctures on each side. Palpi with apical 

 joints securiform, of maxillary moderately so, of labial very widely 

 so and longer than penultimate joint. Antennae stout, subfiliform; 

 joints 5-11 depressed, apical joint very little longer than penul- 

 timate. Prothorax ver}^ little broader than head (5-2 x 5*2 mm.), 

 convex; sides parallel, roundly narrowed to base; anterior angles
