more produced and acute, and the thorax being a trifle broader anteriorly, and conse- 

 quently less semioval. It may be distinguished as melantho var. macra. The species 









agrees with Lebia in all its essential characters, and cannot belong to Chaudoir's 

 Pcecilostola, the type of which has dentiform apical angles to the elytra, as it wants

the remarkable convexity of body and the short and broad lobes of the tarsal joint, 



which alone justify the separation of Poecilostola from Lebia *.

The genus Dianchomena, Chaud., was separated from Lebia on account of its edentate 

 mentum (like Aplielo g enia) and convex head* The species thus brought together are 

 less heterogeneous than in Aphelogenia, but still sufficiently so to demonstrate the 



artificiality of the 

 group ; they are d

shorter in form, might afford good ground for considering that we have here to deal with a genus distinct from 

 Lebia. It is also from Ega, on the Amazons. Lebia ditissima : lsete viridi-senea, elytris splendide aurato- 

 cupreis, tibiis tarsisque piceo-nigris, antennis (brevibus), basi viridi excepta, ruf o-piceis ; 10 millim. The form

of the elytra nearly as in L. melantho var. macra. The structural characters seem to me insufficient to separate 

 these insects generically from the Lebice of the group sulcipennis, xanthopleura, and allies.
