males were of the usual form, but the females were all of the variety hryonicB. P. 

 Callidice, I found the males of this " mountain white " common on June 15th, flying 

 over the Moraine (5751 feet), between the Rhone G-lacier Hotel and the foot of the 

 Rhone Grlacier ; the females were scarce. This species is quiet on the wing and 

 difBcult to capture ; it occasionally rested on the few low flowering plants on the 

 Moraine, but had to be approached with great caution. This species seems to be 

 somewhat local, for I only saw one other specimen, in a meadow at Zermatt. 



Anthocharis Belia, var. simplonia, common, but worn, in the St. Nicolua Yalley, 

 middle of June ; at a thousand feet higher, however, in the Schmutt Valley, Zermatt, 

 it was in very fine condition. A. cardamines, not uncommon at Zermatt in June. 



Leucophasia sinapis, Saas Valley, June and August, up to 2800 feet, common. 



Colias Phicomone, common, July 27th, in the meadows below Saas Fe Glacier, 

 6200 feet. C. Hyale, generally common in August, up to 4500 feet ; very abundant 

 in June. 



Gonepteryx rhamni, a few at Stalden in June. 



Thecla w-alhum, a few worn, at rest on UmlellifercB in the Vallee des Ormonts, 

 beginning of August. T. rubi, not uncommon, Zermatt, in June. 



Polyommatus virgaurecB, var. zermattensis, in the greatest abundance at the end 

 of July, Saas-im-Grund ; females did not appear in any numbers until males were 

 nearly over. P. Hippotho'e, var. JEurybia, a few worn specimens end of July, Saas- 

 im-Grund ; this appears to be rather an early species, for I met with it in June both 

 at Andermatt and Zermatt. P. Alciphron, var. Gordius, of this lovely species I 

 took five specimens, three at Saas-im-Grund end of July, and two in the St. Nicolaus 

 Yalley end of June. P. Dorilis, rather common, Vallee des Ormonts, 3000 feet, 

 beginning of August. P. Phlaas, Brunnen, common but very worn, 1st June. 



Of the " blues " I took nineteen species, viz. : — Lyccena Mgon, very abundant, 

 Brunnen, beginning of June. L. Argus, in profusion end of July, Saas Valley, up 

 to 7000 feet. L. Optilete, a few very worn end of July, Saas Valley. L. Baton, one 

 specimen at Stalden in June. L. Pheretes, orhitulus, and Eros, a few worn in the 

 Saas Valley at 5200 feet, end of July ; probably they were nearly over at this eleva- 

 tion, for at 7000 feet on the banks of the Mattmark See they were common and 

 fine. L. Astrarche (^i^esiis), generally distributed, but never very common, occurring 

 in June and July. L. Icarus {Alexis), Brunnen and Stalden, fairly common. L. 

 lEumedon, common in Saas Valley, middle of June ; Mattmark See, end of July. 

 L. Escheri, one or two, Stalden, end of June. L. Bellargus {Adonis), very abundant 

 at Brunnen, beginning of June. L. Corydon, common, Saas-im-Grund, end of July. 

 L. Hylas, Vallee des Ormonts, 3700 feet, a few in August. L. Damon, very common, 

 Vallee des Ormonts, 3000 feet, beginning of August. L. Donzelii, of this scarce 

 " blue " I took a series at the end of July along the zig-zag path leading from Saas- 

 im-Grund to Saas Fe. L. minima {Alsus), very abundant but worn, at Brunnen, 

 beginning of June ; very fine, middle of June, at Andermatt, about 3000 feet higher. 

 L. semiargus {Acts), generally distributed and somewhat common, from 1500 to 

 5500 feet. L. Arion, a few at Brunnen, beginning of June, mostly worn ; at higher 

 elevations, viz., at Stalden and Zermatt, the species was represented by the form 

 obscura. 



Nemeobiua Lucina, not uncommon at Brunnen, beginning of June.
