what I have seen in any Carenid before. Two specimens ; one 

 shows a single strong puncture on the declivous part of the base 

 of each elytron, the other has no punctures on the base. 



Carenum vicinum, n.sp. 



Elytra of a dark blue, almost black in the middle, but becoming 

 a fine purple towards the sides, the margins cseruleous, the pro- 

 thorax black with a violet margin, head, legs, and underparts of 

 prothorax and abdomen black. Head subquadrate (4J x 5 J mm.), 

 frontal sulci almost parallel, a little sinuate, diverging in front as 

 usual, an obsolete transverse impression behind them ; the pre- 

 ocular processes prominent ; the eyes not prominent, one supra- 

 orbital puncture above each eye. Prothorax transverse (5:^ x 8 

 mm.), rather convex, broadest at the posterior angles, rounded 

 and a little narrowed to the anterior angles, these very slightly 

 produced ; the posterior angles rounded off ; the margin sharply 

 sinuate on each side of the base, thus giving it a shortly lobate 

 appearance ; the lobe very gently rounded and emarginate 

 in the middle ; the marginal border wide, sinuate behind, 

 and widened to form a conspicuous angle on each side of 

 the basal lobe ; the median line lightly impressed, its course 

 crossed by very fine transverse striolse ; the basal part of the 

 prothorax not defined by a transverse line; only two marginal 

 punctures discernible on each side, one near the anterior angle, 

 the other at the posterior angle. Elytra Isevigate, ovate, a very 

 little broader than the prothorax (11 J x 8J mm.), gently rounded on 

 the sides, very slightly narrowed to the base ; the humeral angles 

 well marked and upturned, the base truncate and steeply declivous 

 between them ; the marginal border narrow and reflexed, a row 

 of fine punctures within it; on each elytron a large discoidal 

 puncture towards the apex, and a few punctures in a single row 

 on the base. Anterior tibise bidentate externally, the exterior 

 ridge with four projections above the large teeth, inferior ridge 

 serrate, reaching the apex of the tibiee, the apical plate with a 

 sharp projecting spur at the apex.
