The dilated sides of the thorax form a distinct angle, 

 but the space between that and the anterior angle is 

 quite straight ; the surface is thickly and coarsely punc- 

 tured, the punctures tending to confluence, without 

 glossy granules in the interspaces. The rows of foveolae 

 of the elytra are very distinct, and lie in shallow furrows. 

 A single male.

Ovatum, fusco-aeneum ; capite rotundato, bidentato ; 

 thorace angulatim dilatato, lateribus ante augulum sinua- 

 tis, supra crcberrime punctate, punctis annulos nitidos 

 formantibus, interstitiis opacis : elytris humeris bicarinu- 

 latis, lateribus bicarinatis, callo apicali tri-tuberculato, 

 supra striatis hand foveatis, interstitiis multipunctatis ', 

 corpore subtus punctate, nigro, metasterno nitido.

Hah. — Amazons; rather common. 



Distinguished by its small size, the even surface of its 

 thorax and elytra, without foveolce or depressions, and 

 especially by the sculpture, which consists of the usually 

 shallow circular punctures, but each forms a shining ring, 

 contrasted with the opacity of the rest of the surface. 

 The inner carina of the elytra ends abruptly before the 

 middle; in this respect it agrees Avith D. aspericollc, I). 

 fuscocuprcuvi, and D. siihmdallicum. 



C. Deltochilum fiiscocupreiim, n. sp. 



Oblongum, fusco-cupreum, vix nitidum ; capite rotun- 

 dato, clypco dentibus duobus approximatis ; thorace antice 

 valdo angulatim dilatato, ante dilatationem sinuato, 

 supra crebre punctate, interstitiis dense nitide granu- 

 latis; elytris lateribus vix rotundatis, callo humerali 

 bicarinulato, apicali quadrituberculato, lateribus bicari- 

 natis, supra striatis ot distincte lineatim foveatis, inter- 

 stitiis punctatis ; corpore subtus nigro-aeneo, punctate, 

 nitido.
