prothorax subdepressed on disc, liglitl\' angustate to the wide 

 base; elytra long, depressed on disc, impunctate; anterior tibia? 

 unidentate. Head, antennse, legs, and undersurface black; 

 prothorax black, with a purplish tinge towards sides, viridescent 

 in marginal channel; elytra viridescent, with violaceous reflec 

 tions. 



Head large, convex (5 mm. across eyes), Isevigate; anterior 

 angles rounded, almost as prominent as eyes ; frontal sulci 

 obsolescent, only indicated and linear on each side of clypeus; 

 clypeus quadridentate, outer teeth (at each side of labrum) pro- 

 minent, sharply triangular, inner teeth similar, but less developed; 

 orbits rather small, rising in a gentle curve from head and 

 enclosing eyes at base; eyes deeply set in orbits, subprominent, 

 not more prominent than orbits; two supraorbital punctures 

 close together on each side. Prothorax as wide as head, longer 

 than broad (6x5 mm.); disc a little depressed, not declivous to 

 base in middle; apex truncate; anterior angles not prominent; 

 sides parallel, gently narrowed to base; posterior angles obsolete; 

 basal angles obtuse; border narrow, thicker at basal angles, 

 lightly sinuate opposite transverse basal impression, this impres- 

 sion well marked; marginal channel narrow, bearing two setiger- 

 ous punctures as usual in the Carenides (posterior at place of 

 posterior angle); median line lightly impressed; basal area well 

 defined by a transverse impression. Elytra elongate (1 2-5 x 5-2 

 mm.), widest about middle, strongly declivous on sides and apex; 

 disc a little depressed along suture; base rather strongly emar- 

 ginate; a raised, rounded, oblique, basal ridge extending inwards 

 from humeral angle for three-fourth the width of each elytron; 

 a deep punctate furrow behind this basal ridge; apical curve 

 of elytra wide, apex itself projecting beyond lateral border 

 in a short triangular obtuse prominence; lateral border narrow 

 towards base, very thick on apical third, strongly and widely 

 upturned at shoulder. Ventral segments, posterior coxse, and 

 posterior trochanters impunctate. Anterior femora narrow, ante- 

 rior tibiae wide, unidentate at apex. Length, 23; breadth, 5-2mm.
