202 ON THE CARENIDES (FAM. CARABID.E), 



elytra ovate, bipunctate on apical half, inflexed margins wide 

 behind first ventral segment ; anterior tibife bidentate. Head 

 and under surface black, prothorax shining black with wide 

 violaceous margins, elytra shining violet-purple (inflexed margins 

 metallic). 



Head light, subquadrate (3"2 x 45 mm.), rather depressed; 

 frontal sulci sinuate, very lightly divergent posteriorly, a wide 

 curved impression connecting their extremities, their anterior 

 out-turned part very lightly marked ; preocular process small, 

 prominent; eyes convex, strongly enclosed behind; a sulcus above 

 eye, becoming wider and curving downward behind orbit; two 

 supraorbital punctures on each side. Prothorax transverse 

 (4'2 X 6 mm ), lightly convex, declivous to base; a well-defined 

 depressed space before basal margin ; sides rounded ; posterior 

 angles not marked ; anterior angles lightl}^ advanced, obtusely 

 rounded; border wide, reflexed, strongly sinuate and widened to 

 form prominent angles on each side of base, passing round anterior 

 angles; base rounded on each side and emarginate in middle; a 

 short wide oblique impression on each side of posterior declivity 

 half-way between median line and basal angles ; median line 

 strongly impressed ; three marginal punctures on each side. 

 Elytra ovate, a little bi'oader than pi'othorax (9 x 6 -3 mm.), 

 depressed, lightly declivous to apex; base truncate; sides strongly 

 rounded, narrowed to base ; border narrow, reflexed, lightly 

 upturned at humeral angles ; a row of fine punctures along 

 marginal channel; four fine punctures in a single row on base of 

 each elytron. Legs as in C. planipenne. 



Length 19-5, breadth 6-3 mm.

Allied to C. planipenne, from which it differs by colour, smaller 

 size, the much less erect elevation of the border of the elytra at 

 the humeral angles, &c. From G. fugitivum, Blkb., it appears to 

 differ by the shape of the posterior part of the prothorax, and it 

 most probably has the elytra flatter and less shortly rounded at 

 the humeral angles. It resembles C. vicinum, SL, from which
