CA.RENUM VENUSTUM, n.sp. 



Levigate, elongate, convex, parallel, disc of elytra depressed; 

 head large, lightly transversely impressed posteriorly, suborbital 

 channel divided longitudinally^ in middle by an oblique ridge; 

 prothorax convex, a little broader than long, sinuate-angustate 

 posteriorly; elytra bipunctate posteriorly, humeral angles erect, 

 inflexed margin narrow behind first ventral segment; anterior 

 tibise bidentate; intermediate tibise lightly incrassate, a slender 

 elongate acute tooth externally at apex. Black, upper surface 

 very highly polished, lower surface piceous; lateral channels of 

 prothorax faintly tinged with blue; elytra subviolaceous, metallic 

 purple on declivities of sides, apex and base. 



Head Isevigate, large (3 '5 x 5 mm.), convex, declivous to anterior 

 margin, lightly and widely impressed across middle behind 

 frontal sulci; these sulci very deep, divergent; clypeus with 

 median part trisinuate; preocular process small; preocular sulcus 

 distinct, wide, shallow; eyes depressed, deeply embedded in 

 orbits, hardly more prominent than preocular processes; orbits 

 sloping gently to sides of head, not thick or prominent ; two supra- 

 orbital punctures on each side. Labrum trisinuate. Maxillary 

 palpi with apical joint compressed, subsecuriform ; labial with 

 penultimate joint short, thick, apical joint very widely securiform. 

 Antennae light, not short, more slender to apex; joints 5-10 com- 

 pressed, apical joint oval. Prothorax convex, a little wider than 

 head (5x5-8 mm), declivous to base; basal part depressed, 

 defined by a straight transverse line ; sides parallel, obliquely 

 narrowed to base; posterior angles not marked; a wide light 

 sinuosity a little before base on each side; basal angles hardly 

 marked; base rounded; anterior margin truncate; anterior angles 

 lightly marked, obtuse; border wide, reflexed, narrowed on middle 

 of sides, widened at antei'ior angles, more widely reflexed behind 

 posterior marginal puncture, thick on base; median line strongly 

 impressed; a large round shallow fovea on each side a little before 

 the basal angles; two marginal punctures on each side. Elytra 

 of same width as prothorax (11 x 5-8 mm.), convex, depressed on
