seen again. Single specimens of LyccBiia arion var. ohscura were 

 obtainable in rare perfection on and after June 18th. Polyom- 

 matus hylas first appeared in this district on June '21st (males 

 only), though commonly met with at lower elevations — near 

 Montreux, &c. — earlier in the month. The following additional 

 "blues" were all more or less abundant round Berisal during 

 our stay : — P. alexis, P. hellargus, P. astrarche (with one ab. 

 alio us), P. eumcdon, Cupido minima and Nomiades semiargus. 



It was a pleasure to record the first male CJirysoplumus alciphron 

 wai'.fiordius on June 20th. A small race of this species was abundant 

 just below Berisal in July last year, but specimens reared there- 

 from and emerging this season are but little below the average 

 size of specimens taken near Vernayaz in 1905. The species 

 hybernates invariably as a larva, never as an ovum, in my 

 experience, and when once the young larvae can be induced to 

 recommence feeding in the spring there is little difficulty in 

 bringing them to maturity. 



Parnassiiis apollo was fairly common by June 17th about the 

 road and cliffs towards Refuge II., and Mr. Griffiths and myself 

 were both fortunate in finding one or two full-grown larvas of the 

 species. My own, taken on the bare ground on June 20th, spun 

 up at once, and produced a male butterfly on August 11th. 

 P. mneniosyne was already out on the steep slopes below the 

 hotel on June 17th, and on every subsequent day in increasing 

 numbers ; also in the Steinenthal on June 20th. On this day, 

 too, the first Colias phicomone were met with — three specimens — 

 and Mr. Griffiths also obtained one much lower down, near 

 Refuge II. C. palceno was neither expected nor seen up to the 

 time of our leaving ; C. hyalc was generally common. 



Papilio madiaon was common from June 16th, especially 

 round Refuge II. On the next day it was tantalizing to find 

 three (presumably plum- or sloe-fed) P. podalirias feeding in 

 puddles near the Ganter Bridge, while the writer found it needful 

 to plod his way down to one of the outlying settlements near 

 Brigue to obtain the plum-leaves required by a brood of Zephyrus 

 hetulcB larvae previously obtained near Glion. On this same day 

 Aporia craUegi was flying, larvae and pupae of which were abun- 

 dant on the mountain-ash trees round the hotel. Leptosia 

 sinapis and Euchloe cardamines were common, with Pieris napi 

 var. bryonies (females) in very fine condition. On June 15th, in 

 one spot just above Berisal, Anthocharis simplonia was so abun- 

 dant that about twenty specimens were netted in as many 

 minutes, and it continued common but far less local and easily 

 obtainable during the remainder of our visit. 



June 16th, a superb brilliant day, spent on the beautiful 

 stretches of road up to the Hospice, convinced us that our better 

 ground for the time being lay below rather than above Berisal. 

 Nevertheless, a fair number and variety of larvae and pupae from
