anterior tibiae bidentate. Black, prothorax and elytra widely- 

 margined with green. 



Head 5-2 mm. across eyes, subdepressed, smooth; frontal sulci 

 long, deep, diverging backwards, anterior part turning outwards 

 in a light linear course; clypeus with median part emarginate, 

 declivous, intermediate angles strong, dentiform; eyes convex, 

 not prominent; orbits large, rising gently from sides of head, as 

 prominent as and enclosing eyes; two supraorbital punctures on 

 each side. Prothorax a little broader than long (5 x 55 mm.) 

 depressed on disc, not declivous to base in middle; sides sub- 

 parallel; narrowed gently anteriorly before marginal seta, widely 

 .rounded at posterior angles, lightly sinuate on each side of base; 

 anterior margin truncate; border narrow, hardly produced at 

 anterior angles, stronger and continuous between posterior 

 marginal setae. Elytra hardly as wide as prothorax, elongate- 

 parallel-oval (12x5-4 mm.), lightly depressed towards base; 

 strongly and subobliquely declivous on sides; humeral angles 

 rounded; base truncate; each elytron terminating in a strong 

 cylindrical sharply pointed mucro; a row of separate punctures 

 along sides; four punctures on base of each elytron. Ventral 

 segments 3-5 bipunctate; apical segment with reflexed edge 

 foveate on each side of" apex. Legs light; posterior coxae and 

 trochanters impunctate. Length 23*5, breadth 5*5 mm. 



Hah. — W.A.: ISorseman (W. A. Sayer; Coll. French; unique). 



This species is characterised by its long narrow parallel form; 

 it belongs to the C . mucroiiatum group, in which the elytra are 

 bimucronate at the apex. From C mucronatum Macl., it is at 

 once distinguished by its smaller size, much more narrow and 

 elongate form, longer apical mucrones, &c. It is more allied to 

 C. leal SI. (the other species of the group), with the description 

 of which it agrees in the general characters of head and prothorax, 

 but from which it is evidently distinct by its more slender form; 

 elytra with margins of depressed discoidal area not "sharply 

 defined " nor ending in a subtuberculate elevation on each side. 

 The apical declivity slopes evenly to the long pointed apical 

 mucrones, and the disc is only depressed (slightly) on the anterior 

 half.
