Allied to D, Hyppona (Buquet) . The head is of very 

 similar shape, and the two species agree in the outline 

 of the elytra and form of the carinae, but the wholly 

 different colour and sculpture amply distinguish them. 

 The curious notch in the edge of the thorax behind the 

 anterior angle also distinguishes our species. In this 

 feature, it seems to agree with D. Burmeisteri (Harold) 

 which also inhabits Equador, but this latter species does 

 not possess the glossy tessellate patches of the elytra, and 

 is much larger (11-13 lin.).

Rotundato-ovatum, cupreo-fuscum, sub-opacum, supra 

 creberrime granulatum ; capite parvo, rotundato, clypeo 

 dentibus duobus paulo distantibus; thorace laterilaus 

 angulato ; elytris minus convexis, carina humerali brevi 

 acuta, laterali prope basin duplici, callo apicali distincte 

 quinque-carinato, supra punctato-striatis ; corpore sub- 

 tus nitido viridi-a^neo. 



c? . Pedibus anticis brevibus, simplicibus, tibiis cur- 

 vatis, tibiis posticis gracilibus, curvatis, intus apice valdo 

 prolongatis, prooessu apice dilatato, obtuso ; metasterno 

 medio tuberculato.

Distinguished from all other species by the prolongation 

 of the inner apex of the hind tibias, which forms a sub- 

 spatulate process nearly as long as the tarsus, and is 

 therefore more developed than the similar structure in D. 

 cJentipes, $ . In general appearance it approaches D. 

 niorhiUosiun, but it is much broader in outline, the elytra 

 being of very broad rounded form. The u])])er surface 

 is opaque, o^ving to the minute and dense sculpture; on 

 the head, this takes the form of very regular jiunctures.
