NOTES ON A BUTTERFLY HUNT IN FRANCE IN 1910. 5 



angular, as in thetis ; their shape suggests the issue of a crossing 

 between two differently- sized species. I do not know whether 

 the displacement of the spots in the under side may be also 

 counted as evidence in this direction. 



In the under side there is something of corijdnn as well as of 

 thetis and icarus ; the colouring is very light, the hind wings are 

 distinctly more yellowish than the fore wings, which are whitish, 

 thus reminding of corydon <? . There is no orange in the mar- 

 ginal lunules of the fore wings. 



I am told that in the locality where the specimen was cap- 

 tured, at a time when icarus were worn and thetis were fresh, 

 these A. thetis and P. icarus swarm, while corydon is rare. As 

 the case stands, evidence seems very much to favour the verdict 

 of A. thetis ^ and P. icarus 5 in decision of the parentage; 

 but, on the other hand, I think that the traits of A. corydon in 

 the specimen, if not readily explainable by aberration, are still 

 sufficient to maintain a doubt. 



I will name this interesting form after its captor, Agriades 

 hybr. neivmani. 



NOTES ON A BUTTERFLY HUNT IN FRANCE 



IN 1910. 



III. — BaSSES-AlPES AND ISERE. 



By H. Rowland-Brown, M.A., F.E.S. 



(Concluded from vol. xliii. p. 327.) 



Since the publication of my last paper in December (' Ento- 

 mologist,' xliii. pp. 322-327) I have had an opportunity of in- 

 specting the little collection of butterflies made by Mr. Warren 

 during our brief halt at Rosans (Hautes-Alpes). A Hesperiid 

 taken by him there turns out to be a male of Pyryus proto, in 

 splendid condition, showing a decidedly greener under side than 

 the specimens in my collection from Albarracin, and on the 

 upper rather lighter than true Spanish forms. So far as I can 

 gather, the discovery of this unmistakable species in the Hautes- 

 Alpes constitutes a record, though it occurs at Digne, in the 

 southern adjoining Department. 



Meanwhile, it is with some diffidence that I proceed to give 

 a short account of our entomological experiences in the Basses- 

 Alpes. Digne is nowadays almost as well known to lepido- 

 pterists interested in the extra-British fauna as the New Forest 

 district to those who contine their attention to the United King- 

 dom. Every year the number of those who " take their walks 

 abroad " increases, and as surely as the fly gravitates to the 

 honey-pot, or perhaps I should say, the moth to the treacle, so
