Genera and Species of Coleoptera. 359 



silkj', the colour varying according to the light, but bordered obliquely 

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

 suture for a short distance towards the scutelluni ; legs long, slender, 

 compressed ; body beneath reddish 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 thomcicus ; but there the femora are clavate. 



Sect. Antennae subclavajformes, breves. Prothorax globosus. 

 Femora clavata. 



Clyhis stenothyreus. 



C. niger ; prothorace albo macvdato ; scutello angustato, albo piloso ; 

 elyti'is planatis, pubescentibus, marginibus apiceque infuscatis ; femori- 

 bus rufis. 



Hub. Batchian. 



Head short, subtriangular in front, roughly punctured, black, with 

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

 large, pale fulvous ; antennte black, subclaviforni, 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 triangidar, densely covered 

 with white hairs ; elj-tra scarcely as broad at the base as the prothorax, 

 then gradually narrowing to the apex, which is trmicate, ^\'ith 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 metasternum bor- 

 dered with white. Length 4 lines. 



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

 knoAvn 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 Stenopterus, Thranius, &c. 



Sect. Antennae lineares, breves. Prothorax globosus vel subglobosus. 



Clytus deterrens. 



C. niger ; prothorace brunneo-rufo ; elytris macula subbasali fasciisque 

 duabus, una pone medium, altera apicali, albis. 



Hab. South Africa (N'Gami). 



Head short, transverse in fi'ont, black, rather sparsely covered with 

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

 white hairs ; scuteUum small, ti-ansverse, roimded behind ; elytra sub- 

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