CERESIUM. 157 



sometimes shorter; fourth shorter, the fifth usually longer, than 

 the third. Prothorax longer than broad, generally subcylindrical, 

 sometimes rounded at the sides. Elytra slightly convex above, 

 usually rounded at the apex. Legs of moderate length ; the 

 femora usually pedunculate at the base, with a clavate thickening 

 towards the apex, sometimes gradually thickened from the base 

 and formed into a fusiform club towards the apex. Acetabula of 

 front coxae open posteriorly, the intercoxal process narrow, scarcely 

 or not dilated at the end; acetabula of the middle coxae not 

 extended to the epimera.

Narrow and elongate, cinnamon-brown in colour, sparsely 

 pubescent, marked above and along the sides beneath with small 

 spots of dense white pubescence ; head with two white spots on 

 the vertex. Prothorax with four laterally placed white spots 

 above two rounded spots anteriorly and two, more elongate, at 

 the base ; also a smaller spot at the middle of each side ; scutel- 

 lum white. Elytra each with six spots two placed obliquely 

 between the base and the middle, three, in a triangle, behind the 

 middle, and the sixth, transversely arcuate, a little before the apex. 

 Antenna) longer than the body ; third joint subequal in length to 

 the first and scarcely longer than the fourth ; fourth much shorter 

 than the fifth or any of the succeeding joints except the last. 

 Prothorax subcylindrical, about one-third longer than its width *. 

 Elytra parallel-sided, rounded at the apex, distinctly and rather 

 closely punctured, the punctures feebler near the apex.

" Close to C. cretatum, White, but without the white spots on 

 the elytra. Eeddish-testaceous in colour and clothed with a short 

 faint greyish pubescence. Head moderately lengthened, very 

 faintly rugose on the vertex ; antennae ciliated beneath. Pro- 

 thorax a little longer than broad, its sides feebly rounded, very 

 rugose on the disc, the rugosities transverse, two pubescent white 

 spots on each side. Scutellum white. Elytra somewhat strongly 



* Although Perroud has described the prothorax as "deux fois et detnie 

 aussi long que large," I have no doubt about the identification of his species; 

 the description which he has given of it is very full, and in other respects, 

 especially as to the position and character of the white spots, very accurate. 

 The genus Rhaphidera, Newm., to which he referred the species, exists only as 

 a narne ; it has never been characterized. In the Catalogue of Gemininger and 

 Harold it appears as Bhaphidodera, Perroud, notwithstanding Perroud's state- 

 ment that he was wholly ignorant of the characters of the genus.
