262 [November, 



found good collecting ground. l^utterflics were in the greatest 

 abundance, more in numbers than in species; L. Dolus, however, 

 occurred for the only time plentifully, in a dried up water-course 

 among lavender. The contour of the hills near Mende, perhaps more 

 so than other parts of the Cevennes, reminded one somewhat of 

 Scotland, but how different in colour ! Instead of the purple heather 

 they were covered largely with a luxuriant growth of lavender in full 

 bloom, the effect of which was very striking. 



A drive of 60 miles by diligence on July 31st in the soaking wet 

 brought us to Le Puy. The country round Le Puy appeared for 

 many miles under a high state of cultivation. Southward we could 

 see against the horizon the mountains of Mezenc, but the distance 

 was too great and the chance of success too doubtful to induce us to 

 undertake an expedition. 



Prom an entomological point of view the Cevennes compare un- 

 favourably with Digne in the Basses Alpes, almost in the same 

 latitude, the number of species being certainly more limited, but it is 

 an excursion full of interest. The little villages and old ruined 

 castles, perched high up on the mountain sides, the Grorges du Tarn 

 with its rapids, and the Grotte de Dargilan present interesting sub- 

 jects, probably more so than many other parts of France, and although 

 the hotels in the oni lying districts are primitive, they are nearly always 

 clean. I may mention that the elevations of the various places 

 visited are as under : — 



Florae 1950 feet above sea level. 



Causse Mejean (about) 3000 



Ste. Enimie 1560 



Chateau de la Caze (about) 1 J60 



Le Rozier 1267 



Mende 2402 



Balsiegcs 2259 



Species observed : — 



Papilio Podalirms, rather a cominon butterfly at Florae ; abundant at Chateau 

 de la Caze. P. Machaon, scarce, a few seen at Florae, and one at Mende. 



Parnassins Apollo, fairly common and generally distributed throughout the 

 Cevennes ; a smaller form than the one occurring at Digne. 



Aporia cratcegi, fairly common at Florae, also on the Causse Mejean, but worn. 



Pieris brassicte and napi, fairly common. P. Daplidice, not unconimon 

 throughout. 



Leucophnsia sinapi.t, fairly distributed but not very common. 



Colias IT_//nIe and Ednsa, common, the former especially abundant in places. 



Oonopieri/x rhaivni and Cleopatra, one of each, Florae.
