BUTTERFLIES IN EASTERN SWITZERLAND IN 1906. 1 ;\ 



flies. Our most interesting discovery was a wood in which Brenthis 

 thore was plentiful, though, unfortunately, the $ s were rather passS. 

 The insect seemed to be a less active flyer than in the neighbourhood 

 of the Walen-See, and it was not unlike Pararge egeria var. egerides in 

 its habits. Its wings appeared to get chipped and torn very soon, in 

 consequence of its way of fluttering through the branches of the trees 

 and shrubs. We took four Limenitis populi&b. tremulae; three of these 

 were in first class condition, the fourth was a poor specimen and we 

 let it go. This insect is not difficult to capture when it comes down 

 from the tops of the trees. It may be interesting to note that two of 

 our captures were made between 10 a.m. and 11 a.m., and the other 

 two between 1 p.m. and 2 p.m. One of the latter was a 2 • Other 

 captures were Chrysophanus hippothoe var. eurybia, Lycaena alcon (1 $ 

 and 1 J , very large), Polyommatiis bellargus ab. $ ceronus, P. escheri, 

 Brenthis inn (abundant), Coenonympha iphis (several g s, but only one 

 5 , all in fresh condition), Erebia stygne, E. euryale, E. li(jea. 



July 4th. — Albula Pass. We walked over the Albula Pass in 

 pelting rain. On our way down some gleams of sunshine enabled us 

 to make a few captures just above Ponte. These included Hesperia 

 carthami, Powellia sao, Brenthis ino (very small), and Erebia ceto. 



July 5th. — Pontresina. Heavy clouds nearly all day. We took a 

 few blues, asleep on flower-beads, and amongst these was one Aricia 

 eumedon ab. fylgia in fine condition. In this aberration the white 

 streak on the underside of the hindwings is entirely absent. 



Jul)/ 7th. — Slopes of the Schafberg. Amongst our captures were 

 Polyommatiis orbitidus, P. pheretes (including ab. 2 caeruleopunctata), 

 Scolitantides baton, Parnassius delius, Pieris callidice (as usual a very 

 active and strong flyer), Melitaea cynihia (several $ s, but only one $ ), 

 M. aurinia var. merope (plentiful), Oeneis a'ello (two $ s), and Erebia 

 gorge var. triopes. All these species were in fresh condition. Just 

 above Pontresina we took also Melitaea maturna var. wolfensbergeri, in 

 good condition. 



July 9th. — Between the Bernina Hospice and Alp Gram. We took 

 a freshly emerged Erebia alecto var. glacialis (the only specimen of this 

 species that we met with at all this season), and several E. gorge var. 

 triopes. We also found E. gorge (type). E. lappona was abundant, 

 and we took a particularly fine specimen of ab. caeca, in which the 

 black dots are entirely absent from the wings. We had not much sun 

 after mid-day ; but after the sun had gone in, we took a good many 

 Melitaea cynihia and M. aurinia var. merope at rest and very lethargic. 

 M. cynihia lay, with its wings expanded, on low bushes about a foot 

 from the gronnd. 



July 10th. — Roseg-Thal and Alp Surovel. Butterfliesveryabundant 

 and varied in species. Our most interesting capture was Melitaea 

 maturna var. wolfensbergeri, which was abundant; the ? s were in good 

 condition, but the $ s were getting over. We also took Lycaena (dam, 

 Tj. arion var. obscura, Aricia eumedon (particularly fine), Polyommatus 

 bellargus ab. 2 ceronus, /'. pheretes, I', optilete, ('alias phicomone, <'. 

 palaeno (fine and fresh), and Militant parthenie var raria. 



July 11th. — On the slopes of the Schafberg. Sunshine at intervals 

 only. We were fortunate in finding the right spot for Erebia flavo- 

 fasciata, and took eleven J s and two $? s, all in firstrate condition ; 

 the insect appeared just to have emerged, and the fringes of nearly all
