AND THE AT.PS OF CENTRAT^ EUROPE. 87 



Directions of Yar. (a.) j^rd. col. darker and duller. 



var. Berisalensis, h'av. (false lierisali, Itnld). The Swiss form. 



lOb.s. — After mueli correspondence, and the examination of many specimens, 

 I am fully assured that this is the Swiss form of .1/. Dciniii', as M. Piingeler 

 supposes : the un.s. is identical, the up.s. differs from that of Deione (from la 

 Valette) only in being darker in grd. col. and having the blk. markings more 

 pronounced. It is beyond my comprehension how anyone can regard either 

 Di'ione or Berisaleiiai^ as a form of Athalhi, the un.s. alone would preclude such 

 a designation. I fail to see even a superficial resemblance, and the life-histories 

 have nothing in common beyond what is common to the whole genus. Further, 

 the 2 broods of Bcrixalcndx come out, one before, and the other after, the one 

 brood of Athalia in the Rhone Valley. On the other hand, besides the close 

 similarity of markings, the broods of Deione and Btiriimlcnds both feed on 

 Linaria, both are regularly double-brooded, appear at approximately the same 

 time, and in both the earlier brood is noticeably the larger ; both, again, are 

 singularly constant in their special characteristics. The difference between the 

 Spanish and S. French specimens of Deione seems to point in the same 

 direction, the Spanish form being as much lighter as the Swiss is darker than 

 the French.] 



Loc. Hitherto only from Martigny (Tour de la Batiaz through 

 the vineyards to Plan Cerisier), and Saillon ; v. e. to vi. e.,and viii. 

 m. to ix. m. ; e.ij., ^lartigny, v. 28/01, ab. (Fis.); vi. 14/02; vi. 

 25/01, rather worn; vi'ii. 27, 1900; ix. 1/99 (Wh.), &c., &c. ; 

 reported also from the vineyards at Varen, vii. 8/02 {Sliddon, identi- 

 fied by Clip.). 



[Obs. — This loc. is a v. likely one, the date, though rather late, by no means 

 impossible, hut specimens intermediate between this and Athnlia are mentioned, 

 which makes one pause before fully endorsing this loc. My correspondence on 

 the subject, and the arrangement of various collections, have made me v. doubt- 

 ful whether half a dozen collectors exist, outside the Iiabitiiex of the Rhone 

 Valley, who really know Berit^alensis when they see it, still less when they do 

 not.] 



Directions of Yar. (a.) 2 v. suffused specimens, becoming almost 



blk. (ir.sc//7.). 



(b.) 2 specimens with the >- mark divided 



thus : X; (^'V.s.). 



[Obs. — The name Berisaloisis is a complete misnomer, it being an open 

 secret that the original type specimens came from Martigny, whence the captor 

 went direct to Berisal, his captures from the 2 places becoming mixed. It has 

 never been taken at Berisal, and it may be safely predicted that it never will be. 

 It is V. likely that specimens from the Simplon Pass purporting to be Bcriau- 

 lenxiK are responsible for much of the confusion through which it has been sup- 

 posed to be a var. of Athalia.]
