The genus Ennya is separated by Stal from Hille on the ground that the corium is 
destitute of a discoidal area; but this is incorrect, for the specimens of Oxygonia 
chrysura which I have seen (which species, together with O. rujfipes, Stl apparently’ 
regards as the typical species of Ennya) have mostly one discoidal area at least present, 
and occasionally two; the tegmina, however, in the group appear to vary in this 
respect in the same specimens, and a thorough revision of the whole is very necessary. 
It is by no means clear why Stal should have adopted the name of Ennya as a genus 
for the reception of Oxygonia rufipes and O. chrysura, for O. rufipes is apparently 
Fairmaire’s type species of Oxygonia (1. c. p.303). I have therefore preferred to retain 
the name Oxygonia instead of Ennya for the species below referred to.

Adippe, Stal, Ofv. Kongl. Vet.-Ak. Férh. 1867, p. 555. 
This genus is chiefly distinguished from Oxygonia in having the outline of the 
pronotum, if viewed from the side, evenly rounded, and the shoulders not, or scarcely, 
prominent; the species, as a rule, are very distinct, and in several cases brightly 
coloured.

In the Vienna Museum collection there isa specimen of Signoret’s under the MS. 
name of Adippe vicina, which is a slight variety of this species. 
An example from Purula is figured.
