fully out when we left. A. luo was frequent on the openings in the 

 woods opposite Guarda, where an odd A. Tliore was taken ; this was 

 more abundant in the steep lianging wood through which the path 

 goes from Pontresina to the Muottas Pontresina. It was here that 

 we met with Oriiia vittigcra so abundantly. A. Euphrosi/ne was still 

 on the wing at Guarda, and A. Lat/ionia, without being in profusion, was 

 fairly common at all places visited except the higher levels. 



Grapta G-alhum and other Vanessce were seen at Guarda, with 

 H. Setnele, Janira, and Mcera. 



The Lyccenids always command one's attention, but we met with 

 nothing of note. L. Pheretes andorbitulus were the blues of our trip, 

 being in profusion in the Heuthal and the Val Tuoi, and common 

 almost everywhere, .fi'ros was often by uo means a bad third. u3^r/oii, 

 seinlarrjiis and minima made up the list of blues that were " common 

 everywhere." Eumedon was frequent, but nowhere coumion. OptiJctc 

 was common where Vaccinium uJirjinosum abounded, especially on the 

 Muottas Pontresina. Avion was frequent, and common in places near 

 Guarda. Damon, Icarus, Cori/dou and Arrjits were common at Guarda, 

 SiVid Astrarche was frequent at Pontresina. Hylas was less abundant, 

 and only an odd specimen each was captured of baton and hellargus. 

 Escheri occurred at Pontresina, and a large form of Alcon with wide 

 border was met with at Guarda. At the latter station a specimen was 

 taken that is possibly a variety of Amanda, but strongly suggests 

 itself to be a hybrid Oorydon X Hylas. "Coppers" were not success- 

 fully exploited, Gordiits and viryaurecs making up the tale. 



Tbe ErehicB met with included Mehimpics, common everywhere ; 

 Go/ye, already alluded to; Epipliron, nowhere common, perhaps hardly 

 fully out; lappona, Mnestra, frequent, both at Pontresina and Guarda. 

 A feature of the U])per slopes of the Val Tuoi was the abundance of 

 E. Pharte and E. Manto, unfortunately beginning to get worn. What 

 was specially noticeable w-as the parallelism of variation of the two 

 forms. In neither species were there any specimens so fully and 

 brilliantly marked as those taken a few years ago at ISt. Anton and in 

 Carinthia, though a few approached it. On the other hand there 

 were all gradations, in Manto from this form to the var. Gcecilia, 

 which was frequent, and in Pharte a similar range to specimens 

 almost without markings, but not one, I think, absolutely without a 

 trace of rusty mark on upper wing. A few Stygne and Medusa were 

 seen, and Tyndarus was often in great force. We were too early for 

 c/lacialis at Pontresina, but it was taken on the ridges above Val 

 Tuoi ; the few taken included the dark and pale forms, including one
