388 Mr. C. O. Waterhouse's descriptions of 



Of the following Species only the females are known to me, 

 C. costata, sp. nov. , 



Elongata, crassa, nigro-fusca, calva ; tliorace nitido, sat 

 crebre subtiliter punctulato, intra angulos posticos im- 

 presso, disco utrinque fossa rotundata; eljtris quadri- 

 costatis, subopacis, subtiliter coriaceis, sat crebre punctu- 

 latis ; abdomine creberrime subtil issime punctulato. 



Long. 14 lin. ; lat. ,5 lin. 



Antennge as long as bead and tborax together, ferru- 

 gineous except the basal joint. Thorax very convex and 

 shining, distinctly swollen before the posterior angles 

 (which are neai-ly right angles), the surface finely and not 

 very thickly punctured ; on each side of the disk is a 

 rather deep round fossa, and in front of each (near the 

 anterior angles) is an indication of another; the usual two 

 impressions near the scutellum are rather large but slightly 

 indicated, the impression within the posterior angles is 

 rather deep. The scutellum is slightly cordiform, nearly 

 smooth. Elytra someAvhat opaque, finely coriaceous and 

 rather thickly punctured, but the punctures are very small 

 ^nd irregular, the costse are moderately raised and shining, 

 the space between the first and second slightly concave.

 calva; thorace nigro nitido, antice arcuatim angustato, 

 convexo, crebre subtiliter punctato, disco utrinque puncto 

 impresso, angulis posticis acutis supra baud impressis ;

Head very thickly, coarsely and rugosely punctured, 

 with no longitudinal impression behind, deeply impressed 

 above between the antennse, the deflexed portion in front 

 deeply longitudinally impressed (narrower above than 

 below), so that there is a well-marked ridge over the base 

 of each antenna; antennge dull rusty, as long as head and 

 thorax together. Thorax convex, broadest at the pos- 

 terior angles, narrowed and rounded in front, regularly 

 arcuate at the sides, rather thickly and finely (but dis-
