326 THE ENTOMOLOGIST. 



to change our ground again, and try the old familiar hunting- 

 grounds of the Basses Alpes. 



Accordingly, on the 6th we packed up our things, and drove 

 to Serres in the Hautes-Alpes, some sixty-five kilometres to the 

 east, the nearest point on the line from Grenoble to Digne, and, 

 the morning being fine until about eleven o'clock, we spotted 

 not a few alexanor on the precipitous cliffs and rough stony 

 slopes which characterize the whole intervening country until 

 the defiles of St. May, with its imposing ruins, are passed. By 

 midday we had reached Kosans (Hautes-Alpes), and while wait- 

 ing for dejeuner took advantage of a momentary gleam of sun to 

 unfurl our nets. Eugonia polychloros was now observed, while a 

 piece of rough ground near the village we found teeming with 

 butterflies, principally a form of Hesperia alveiis, Melitaa phoebe, 

 M. didyma, and P. corydon. But we were not so fortunate as 

 Dr. Vogt, of Paris, who followed us with M, Guerry, of Roanne, 

 two days later, and took quite a number of the rarest of French 

 Melanargias, M. iapygia var. deanthe, not hitherto reported 

 from the Hautes-Alpes, but apparently occurring throughout the 

 hot uplands among the corn-fields, just as I found it some years 

 since under precisely similar conditions on the arid Causse 

 Mejean above Florae, in Lozere. From Rosans to Serres is but 

 a matter of twenty-four kilometres, and collectors in search of 

 deanthe, who have hitherto failed to reach its other known head- 

 quarters by reason of the difficult approach to the Montague de 

 Lure from Sisteron, would do well to make a halt at Serres 

 on their way south, and spend a day or two at the homely 

 Rosans inn, which provided us with an excellent repast, and 

 seemed well adapted for not too-exacting pensionnaires. As far 

 as I can gather there is also decidedly promising country for 

 the entomologist all round Serres, which, like Nyons, is well 

 within the line dividing the Midi from the north of France. 

 Meanwhile, as the Drome appears to have received little atten- 

 tion from lepidopterists, and the late M. Rouast, of Nyons, 

 author of a 'Catalogue des chenilles europeenes connues,' pub- 

 lished at Lyons in 1883, who lived some time at Nyons, left no 

 record of his work in this particular locality, I venture to add 

 in detail a list of all the butterflies observed by Mr. Warren 

 and myself during our visit to the southern part of the depart- 

 ment, June 28th to July 6th : — 



Hesperiidje. — Cardiarodus lavaterce, C. alcecB ; Hesperia alveus 

 (PiosslUs), H. malvce ; Pyrgiis sao ; Pamphila sylvanus ; Thymeli- 

 cus actceon, T. lineola, T.flavus. 



Lyc^nid^. — Chrysophanus alciphron var. gordius (one ab. 

 midas, male, taken by Mr. Warren, July 3rd) ; C. dorilis, C. 

 phlceas ; Lyccena arion, L. iolas ; Ciqndo minwms, C. sehrus ; 

 Nomiades semiargus ; Polyommatus admetus var. rippertii, P.
