10 Mr. C. C. Babington's Descriptions 



et puncto apicis castaneis, subtus niger, antennis pedibusque 

 fuscis. (L. c. 3| ; lat. 2 lin.) 



Ovate, black, shining, smooth, depressed. Head with two 

 transverse red spots on the crown. Antennae fuscous. Thorax 

 transverse, very short, broadly emarginate in front ; the angles pro- 

 minent and acute ; hinder margin nearly straight, the angles slightly 

 prominent and acute ; the anterior angles broadly castaneous. 

 Scutellum black. Elytra ovate, black ; a little beyond the mid- 

 dle, near the outer margin, there is a triangular castaneous spot, 

 and within the apex another small round one, connected with the 

 former by a slender castaneous line, which is continued beyond 

 the apical spot, but interrupted by the suture ; the usual punc- 

 tate lines on the disk but faintly marked. Under side black, 

 with a small red spot on each side of the segments of the abdomen. 

 Legs fuscous, the hinder ones darker. 



Hab. Callao. 



The appearance of this insect is very similar to C. vilreus, but 

 it differs in shape, colour, and in the marks at the end of the 

 elytra. It has the structure of Erichson's genus Ilyhius (as indeed 

 has C Grapii referred by Mr. Stephens to Agahus), namely, the 

 unequal posterior claws by which it is at once separated from C. 

 vitreus. I cannot let this opportunity pass without remarking the 

 utter uselessness of these generic divisions, since, as sections, they 

 separate insects so closely allied as C. vitreus and Saulcyii.

 Ovatus, niger, Isevis, depressus, thoracis angulis anucis, ore, an- 

 tennis lunulis 2 frontalibus pedibusque anticis rufescentibus, 

 elytris macula parva lalerali oblonga fenestrata, subtus niger,

Ovate black, very minutely reticulate-strigose. Head with two 

 transverse usually confluent lunules on the crown, and the mouth 

 and antennae rufescent. Structure of the thoiax as in the last, 

 the anterior angles rufescent, and the posterior not prominent, 

 and slightly rounded. Scutellum black. Elytra ovate, black; a 

 little beyond the middle, near the outer margin, is a minute ob- 

 long fenestrated spot ; the usual striae are formed of numerous 

 punctures, and are strongly marked. Body beneath black. Legs 

 rufescent, the posterior pair fuscous.
