on the thorax and elytra of minute oblong granules, with 

 shallow circular pits in the interstices ; the strife are 

 nearly as distinct as in D. morhillosum, and have large 

 shallow distinct punctures. 



3. Deltochilum harhipes, n. sp. 



Oblongum, fusco-seneum, sub-opacum; capite rotun- 

 dato, clypeo bidentato ; thorace antice sub-angulatim 

 dilatato, creberrime punctato et granulis nonnuUis ele- 

 vatis nitidis consperso, dorso postice longitudinaliter 

 impresso; elytris humeris bicarinulatis, callo apicali 

 quadricarinulato, lateribus bicarinatis, supra foveolato- 

 striatis, interstitiis multipunctatis ; pygidio seneo sparsim 

 punctato; corpore subtus nigro, nitido. 



cJ . Trochanteribus et femoribus subtus fulvo-barbatis, 

 tibiis posticis baud elongatis, sensira dilatatis.

Hah. — Upper Amazons. 



Similar to D. suhmetalUciim in shape of body and head, 

 but differing in the rows of large shallow foveolse on the 

 elytra, in the colour of the under-surface of the body, 

 &c. The surface of the body is throughout minutely 

 shagreened, and the foveolse of the elytra have each in 

 the centre an umbilicate prominence, which is the form 

 also of all the other punctures ; between the punctures 

 are a number of shining spots, or granules, similar to 

 those of the thorax. The thorax does not form a sharp 

 angle at its dilatation, but is rounded. Seven examples, 

 c? and ? . A common species. 



4. Deltochilum aspericolle, n. sp. 



Sub-ovatum, fusco-cupreum, sub-opacum ; capite rotun- 

 dato, antice bidentato; thorace antice angulatim dila- 

 tato, supra crebre rugoso-punctato : elytris lateribus 

 regulariter rotundatis, humeris indistincte bi cannula tis, 

 callo apicali 4-tuberculato, lateribus bicarinatis, supra 

 distincte foveolato-striatis, interstitiis dense punctatis ; 

 mesosterno cupreo, nitido. 



S . Femoribus posticis prope basin subtus abrupte 

 dilatatis; tibiis apicem versus curvatis et dilatatis.
