silk}', the colour vai-ying accordinfr to the light, but bordered obliquely 

 in front by a naiTow line of straw-yellow, which ascends parallel to the 

 suture for a short distance towards the scutellum ; legs long, slendcir, 

 compressed ; body beneath ri'ddish brown, the abdomen black. Length 

 7 lines. 

 A handsome and remarkable species, and not to be assimilated to 



any other known to me. In outline only it may be compared to 



C. thoraciciis ; but there the femora are clavate.

Head short, subtriangular in front, roughly punctm'ed, black, with 

 two white hairy stripes between the eyes and antennre ; eyes rather 

 large, pale fulvous ; antennce black, subclaviform, half the length of the 

 body ; prothorax nearly globose, wider than the head, roughly punc- 

 tured, black, a line at the side and eleven spots on the disk composed 

 of white hairs ; scutellum elongate, narrowly triangular, densely covered 

 with white hairs ; el}i;ra scarcely as broad at the base as the prothorax, 

 then gradually naiTowdng to the apex, which is truncate, with the outer 

 angle acute, nearly flat above, and, but slightly, bent in at the sides, 

 pale fulvous, darker towards the apex and along the exterior margin, 

 and very sparsely pubescent ; femora short, moderately clavate, yellow- 

 ish red, tibiae and tarsi dark brown ; body beneath black, the abdomen 

 glossy, with the two basal segments and sides of the metastemum bor- 

 dered with white. Length 4 lines. 



I am unable to compare this well-marked species with any other 

 known to me. The flat elytra very imperfectly covering the abdo- 

 men, and in some degree the habit, suggest an affinity, or rather an 

 analogy, with Stenoptenis, Tliranlus, &c.

Head short, transverse in front, black, rather sparsely covered with 

 short white hairs ; prothorax globoso-ovate, brownish red, with scattered 

 white hairs ; scutellum small, transverse, rounded behind ; elytra sub- 

 truncate at the apex, black, closely covered with short hairs, a round
