log in this way. It occurs also in Devonshire and Derbyshire, as well 
as in other parts of Scotland, in quickly running atreams. 
"With this I conclude my remarks on our British Oyrini, regretting 
very much they are of so unsatisfactory a character ; this cannot, how- 
ever, I think, be helped, as the species are very closely allied and yet 
variable. A good collection, containing series of the different species 
from various parts of the country, would be very interesting ; but these 
insects appear to be much neglected by collectors.

DESCRIPTION or a NEW SPECIES of WEST AFRICAN PAPILIO, HITHERTO 
CONSIDERED TO BE THE P. ZENOBIA OF PABRICIUS. 
BT AETHUB G. BUTLEE, F.L.8., F.Z.S. 
In his " Systema Entomologise," p. 503, n. 255 (1775) Fabricius 
has characterized a Papilio under the name of Zenohia, as follows : — 
" Alae nigrse, fascia lata alba, anteriorum interrupta, nee marginem at- 
" tingit. Margo sinuhus albis. Subtus concolores, at posticse basi 
"flavse, nervis striisque atris." 
" Habitat in Sierra Leone. Mus. Banks." 
From a comparison of the type-specimen, which perfectly answers 
to the above description, with the specimens named as Zenohia in the 
National Collection, I find that it entirely differs from them, being 
identical with P. Messalina of Stoll (Suppl. Cramer, pi. xxvi., figs. 2, 
2 b) ; the latter will therefore become a s^ynonym of Zenohia, whilst 
our insect hitherto supposed to represent the Fabrician species will 
have to be re-named. I accordingly characterize it as 
Papilio CTPE(EoriLA, sp. nov.
