and Species of Coleoptera. 31 



flat triangular space between the eyes is not bounded by a 

 raised line, the eyes are more widely apart, owing to the 

 greater breadth of the head, the antennae have the seventh to 

 the tenth joints transverse, the prothorax larger, with its 

 sides gradually rounded from near the base, giving less pro- 

 minence to the anterior angles, and the strite on the elytra 

 more distinctly punctured. The intermediate and posterior 

 tarsi are also shorter. 



Calydonis. 



Caput exsertum, trans vcrsum ; cljjpeas a capito hand discretus, apice 

 integer ; labrum breve ; anteniite breviusculse, gradatim'crassiores. 

 Prothorcuv transversiis, lateribus fortiter marginatis. Elytra ob- 

 longa, apice Integra. Pedes subelougati ; femora hand clavata ; 

 tibice vix curvatte ; tarsi subtus dense pilosi, anteriores articnlis 

 tribu3 basalibus transversis, ultimo elongate, infra canaliculato. 

 Processus abdomino-intercoxalis triangularis ; mesosternum antice 

 V-formi excavatum. 



This genus is allied to Camaria, but is differentiated by its 

 short clypeus not marked off from the head, and by the trans- 

 verse terminal joints of the antennce, which are consequently 

 much shorter. The elytra are not striated as in Camaria^ and 

 are more parallel at the sides. 



In the two species described below the tarsi are clothed be- 

 neath with a dense silky ochreous pile. 



Calydonis refidgens. 



C. oblonga, Isete purpureo et viridi varians, antenuis tarsisque nigris ; 

 articulis tertio qiiartoque antennarum brevibus, longitudine lequa- 

 libus. Long. 8-9 lin. 



Hah. Amazons, Panx. 



Oblong, brilliant metallic purple and green, varying accord- 

 ing to the light ; head flnely punctured, depressed below the 

 eyes, which in certain positions show spots of rich purple ; 

 antenna3 black, third and fourth joints oblong, the rest, except 

 the last, transverse, all the joints coarsely punctured ,• pro- 

 thorax much narrower behind, finely punctured ; scutelluin 

 scutiform ; elytra finely seriate-punctate ; last joint of the 

 intermediate tarsi shorter than the rest together. 



Calydonis cuprea. 



C. oblonga, cnpreo-mctallica ; capite antice baud depresso ; arti- 

 culis tertio (^uartoquc magis elongatis. Long. lin. 



Hah. Para.
