ate, though very rehictantly, the leaves of the garden carrot ; only two reached the 

 pupa state. The cold weather experienced in England during July and August 

 affecting the larv£e no doubt very prejudicially, after the warmth of Digne. P. 

 Machaon, much scarcer than the two preceding species ; the form is lighter in colour 

 than the typical European specimens, and the black markings, especially on the 

 under-side, are much reduced in size. The larva was observed on Ferula communis, 

 a large umbelliferous plant very common on the dry hill sides. 



Thais Rumina, var. Medesicaste. Digne is probably the northern limit for this 

 species, but the conditions seem very suitable, as it is certainly common. The 4th 

 of June was very late, and only a few were obtained fine, though occasional speci- 

 mens in fair condition were noticed quite late in June. Mr. Nicholson discovered 

 the eggs and larvae in great abundance on Aristolochia pistolochia, a plant which 

 only grows on the sides of the mountains facing the south. The Inrvre were in all 

 stages, the young ones resting on the under-sides of the leaves and in the tubes of 

 the curious flowers, the full fed larvae lying concealed at the roots. The var. 

 Honoratii occurs every season, but appears to be usually very scarce. 



Parnassius Apollo, common, but local. A very fine form, the specimens being 

 nearly half an inch broader in expanse of wing than the Swiss ones. P. Mnemosyne. 

 Mr. Eaine, of Hy^res, whom we met at Digne, took this species in June. 



Aporia cratcegi, generally distributed, but not so common as in the Swiss 

 valleys. 



Pieris brassiccB, rapce, napi, and Daplidice, occasionally. 



Anthocharis Belia, a few worn. A. Tagis, var. Bellezina, two specimens, June 

 6th, flying on cultivated ground on the Dourbes. The larvre of thio species are said 

 to feed on Iberis pinnata, a common cornfield weed near Digne, which would account 

 for the species occurring in the locality mentioned. A. cardamines, rather common. 

 A. euphenoides, a few at the beginning of June. 



Leueophasia sinapis, fairly common. L. Duponcheli, not uncommon, but not 

 quite fine, on the higher ground of the Dourbes, June 6th. This species occurs round 

 Digne in May, and is common. 



Culias Hyale and Edusa, Oonepteryx rJiamni and Cleopatra, not uncommon. 



According to Donzel, all the European Theclce occur at Digne. We observed 

 six species, viz., Thecla sphii, a long series among young oak from June 10th to 20th ; 

 the form is remarkably large. T. ilicis, var. cerrl, quite as common as spini, and in 

 the same localities ; both this and preceding species fond of thyme blossoms. This 

 is also a fine form, apparently the only one occurring at Digne ; both J and ? having 

 the orange patch on the fore-wing very bright, in the $ spreading much over the 

 wing. T. hetulcB, larva on blackthorn. T. rohoris, taken by ilessrs. Lemann and 

 Nicholson on July 2nd ; this species had apparently been out some time, for it was 

 then w<jrn ; it is rather partial to privet blossom. T. quercus, on July 3rd. T. ruhi, 

 not unconnuon. 



Polyommatus Alciphron, xar. Gorc^jMS, very common, frequenting thyme blossom. 

 P. Dorilis, Phloeas, and var. FAens, occasionally met with. 



Lycnna [argiades, var. Coretas, common, but worn, beginning of June ; type 

 not observed. L. JEgon and Argus, locally abundant. L. Astrarehe, one or two 

 specimens. L. Icarus, fairly common ; var. icarinus, common. L. Escheri, locallj- 

 abundant, from middle of June. L. Bellargtis, rather common ; var. Ceronus, this 

 "blue" form of the ? appeared to be the prevailing one. L. Hylas, common, but 

 local. L. Corydun, common, beginning of June, the pale south European form.
