no differences among them that I can confidently affirm to be 

 sexual. Some examples are decidedly ovate, others scarcely 

 dilated behind the middle; in four the front tibiae are red, in 

 one black ; in three the pygidium is distinctly more convex than 

 in the two others; in three the apical ventral segment is de- 

 cidedly emarginate behind, in two scarcely emarginate. The 

 species is very distinct from "planiceys, Blackb., not only by 

 its colouring, but also by, inter alia^ the much less strongly 

 rounded sides of its pronotum, the much more strongly convex 

 interstices between the striae of each pair of geminate striae, 

 and the maxillary palpi (especially the penultimate joint) 

 notably shorter.

A. consanguineus, sp. nov. Ovalis; sat convexus; pronoto 

 sparsim subtiliter punctulato, basi utrinque vix sinuata; 

 scutello vix perspicue punctulato ; elytris minus crebre 

 punctulatis; cetera ut A. tetricus, Blackh. Long., 5 1.;

It seems unnecessary to repeat the characters which this 

 species shares with A. tetricus; the diagnosis of that species 

 correctly describes the present one except in respect of the 

 characters noted above, which are strongly marked ones. The 

 front tibiae of this species are red and the apical ventral seg- 

 ment is scarcely emarginate behind. The punctures of the 

 pronotum in this species are very much finer than in A. 

 planiceps, Blackb.; in A. tetricus they are a trifle coarser and 

 stronger than in the latter.
