the differences between the two can be detected only by comparing 

 these two species. In D. cordicollis <? the labrum is only very 

 slightly edged with black, whereas in D. convexicollis it is broadly 

 marginate ; the shape and plication of the head are nearly alike in 

 both species, but while the discoidal part of the prothorax of D. 

 cordicollis is highly raised, it falls abruptly behind above the posterior 

 strangulation ; in D. convexicollis it is regularly convex and more 

 gibbose, and the prothorax itself is a little narrower; the shape and 

 sculpture of the elytra are the same in both species, but they are 

 narrower in D. convexicollis.

 rumque sub-aeneis, antennarum articulis quatuor basalibus, tibiis, 

 femorumque basi rufo-flavescentibus ; labro flavo, baud fusco- 

 marginato ; capite lato, inter oculos valde plicato, collo transversim 

 pUcato-scabroso ; prothorace breve, latitudine longiore, basi apicc 

 angustiore, ad basim baud sensim strangulato, areis dorsalibus 

 duabus modice convexis, transversim undulato plicatis praedito ; 

 elytris elongatis, ad medium modice ampliatis, convexis, apice baud 

 singulatim emarginatis, spina suturali brevi acuta munitis, punctis 

 profundis confertis, ad latera obliteratis, in partem anticam

This species is allied to D. elegantula and also to D. cordicollis, 

 but it is easily distinguished from both these species by the entirely 

 flavous labrum, the sub-cylindrical prothorax, which is slightly 

 attenuated in the posterior part and very little constricted there, and 

 the much more closely set punctures which are also less wide, 

 and which, instead of being of a uniform size as in the two species 

 mentioned above, are slightly broader in the anterior than in the 

 posterior part ; in my $ examples of D. elegantula and D. cordicollis, 

 the sides of the elytra are punctured as far as the outer margin,, 

 whereas they are broadly impunctate in D. zuluatia.
