258 [April. 



Leucophasia Duponcheli : Oulx (?) and Briancon. At the time 

 we did not distinguish this from the common species, so only got two 

 or three specimens. According to M. Bellier de la Chavignerie (Ann. 

 Soc. Ent. Prance, 1869, p. 514), this species is, in France, almost con- 

 fined to the lower parts of the Basses Alpes, and the neighbourhood 

 of Digne, and Aix in Provence. 



Colias Ediisa, var. Helice : Oulx, Chambery, &c. 



Thecla iJicis : round bushes in the Val Anzasca. This and T. 

 o-iihl were the only " hairstreaks " met with. 



Poli/ommatus virgaurefs : Val Anzasca, not numerous. P. Hip- 

 pothoe, var. Euryhia: upper parts of Val Anzasca, and near Macugnaga. 

 -P. Alciphron, var. Gordius : this beautiful " copper " was abundant 

 in the Val Anzasca, flying about, and settling on, the flowers by the 

 sides of the road. The males were by far the most numerous ; a few 

 were also caught at Baveno and near Briancon. P. Dorilis : near 

 Chambery, Briancon, Val Anzasca, &c. ; the males commoner. The 

 alpine form {suhalpina, Speyer) occurred at Macugnaga. 



Lyccena argyrotoxus {=jEyo7i): St. Laurent du Pont, &c., common. 

 I/. Argus : very common in the Val Anzasca ; also on the Col du 

 Lautaret, at Oulx, and Baveno ; most of our specimens are referable 

 to the iorm. uEgidion (Meissner). L. Orion: not uncommon, flying 

 over the road, particularly where muddy, in the lower parts of the 

 Val Anzasca, but local, and generally worn. L. Baton : one at Bourg 

 d'Oisans, and a few at Briancon and Macugnaga. L. Eros : Oulx, and 

 more commonly in the Saas Thai, above Stalden. L. Icarus, ah. icar- 

 inus : Oulx. L. Evmedon : Oulx, and Saas Thai, above Stalden ; no- 

 where common. L. Escheri : Chambery, near Bourg d'Oisans, Oulx, 

 and Stalden, singly. L. Hylas : common at Oulx, Saas Thai. L. 

 Sehrus : Col du Lautaret, Oulx, males only ; we probably passed this 

 species over as the next in many cases. E. semiargiis : common at 

 Briancon, Oulx, &c. L. Cy liar us : rather common on the Col du Lau- 

 taret, and about Briancon, Baveno, and Val Anzasca. L. Alcoyi : Oulx, 

 a few. L. Arion : Col du Lautaret, Oulx, Saas Thai, &c. 



Nemeohius Lucina : Chambery, Val Anzasca, &c. 



Lihythea celtis : I saw, and caught, a single specimen of this S. 

 European species in the Val Anzasca, below Ponte Grande. This was 

 the only one seen. 



Apafura Ilia, var. Clytie : a single specimen of this species was 

 seen, but not secured, on the road side near Baveno. 



Limenitis populi : a fine female near Ponte Grande ; we saw 

 another higher up the valley, but failed to catch it. L. Camilla : I 

 caught a single specimen at Oulx, the only one we saw.
