This species differs from both the male and female of D. honorei 

 to which it is allied, by having no distinct pronotal collum, the 

 pronotum being much shorter, simply conical and not lagenoid ; 

 the gibbose portion of the elytra begins nearer the base and the 

 broadest part is in the middle ; the basal portion is more closely 

 and thickly sculptured than in D. honorei, and the rest of the 

 upper surface is about as coarsely sculptured as the basal part ; 

 the punctures towards the lateral margins and the apex are a very 

 little smaller, and are not or scarcely joined longitudinally in 

 irregular fashion ; the punctures on the disc and near the suture 

 are somewhat oblong and very slightly confluent longitudinally, 

 but do not form more or less long sulci as in the last-named 

 species ; the chief part of the tibiae is reddish. 



The elytra, according to Dr. Horn, appear to be more or less 

 uniformly, though irregularly, thickly and closely punctured ; on 

 the top of the convex portion the individual elongate impressions 

 unite in the form of a chain, but do not form actual elongate 

 sulci, the individual impressions being very marked.

An elongate and delicate species ; 

 shining black with a more or less dis- 

 tinct aeneous or greenish seneous 

 reflection ; head large and very broad 

 in proportion to the collum of pro- 

 notum, smooth, shiny, and convex 

 between the eyes, occasionally slightly 

 depressed ; pronotum lagenoid or 

 flask-shaped, with a long and very 

 narrow collum, which is slightly 

 rugose on its upper surface, dilated 

 part broadest behind middle, smooth, 

 with a very fine central line ; elytra 

 gradually and not abruptly narrowed 

 to base, considerably but gradually 

 dilated behind, not gibbose ; upper 

 surface rather strongly, but not very 

 closely, punctured in front, very finely 

 and diffusely in the centre, and smooth 

 Fig. 127. and glabrous towards apex ; the sculp- 



Derocrania nietneri. ture is, however, a little variable ;
