Before concluding this paper I should like to draw the atten- 

 tion of British " travelling" collectors also to the possibilities of 

 the country immediately south of our little area of occupation. 

 From several of the higher hills in the vicinity we could see 

 Mont Ventous, the last "alp" of any size west of the central 

 chain ; our French friends in a motor-car actually did a whole 

 day's collecting there from Nyons. During the past few years 

 my friend Mr. Henry Brown, of Paris, has worked assiduously 

 both on the northern and southern slopes of this extremely in- 

 teresting mountain, which seems to combine the southern fauna 

 of the plains with not a few of the butterflies associated with the 

 higher Alps. At some future time I hope to deal exhaustively 

 with the Rhopalocera of the beautiful, and entomologically 

 fertile region, east of the Rhone valley, bounded on the north 

 by the Isere and the Drac ; on the south by the Verdon and the 

 Durance. Meanwhile, it is an encouragement to closer investi- 

 gation to know that Vaucluse maintains a butterfly fauna bardly 

 less rich and varied than that of the Mediterranean littoral 

 itself, for while the lower elevations yield such characteristic 

 meridionals as Thais rumina var. medesicaste, Euchloe euphe- 

 noides, Leptosia duponcheli, Libythea celtis, Noiniades melanops, 

 and Lampides telicanus, on the mountain itself occur, besides 

 Erebia epistygne, E. scipio (at 1500 m.), E. neoridas, E. evias, 

 and Parnassius apollo.
