LEPIDOPTERA OF THE GOESCHEXEN DISTRICT. 271 



euphrosyne on the bank near Andermatt. On this bank, too, Aricia 

 astrarcke, Eubolia mensuraria, Melanippe tristata, and the beautiful 

 Psodos quadrifaria were abundant. It is a remarkable fact that 

 not a single Agriades corydon was observed here. 



The weather next morning- was very broken, but a start was made 

 for an exploration of the Goeschenen-Thal, as far as the Dainma- 

 Gletscher, and, as the following morning, bright and sunny, was spent 

 in the part of the valley nearest the village, the observations made 

 are included here. The few opportunities presented suggested that 

 this valley was also excellent, entomologically. To approach the 

 Thai, turn up by the footpath between the Hotel Krone and that ■ 

 directly above, and you come out at once on to an alp swarming 

 with Erebia stygne, E. euryale, E. melampus, E. tyndarus, Pararge 

 maera, Coenonympha darwiniana, Argynnis aglaia, A. niohe, and 

 lots of other species, whilst an unexpected stranger seen here was a large 

 female Arctia caia, crawling on the path. A single, very worn 

 Brenthis thore told its own tale. Entering the pine woods one finds 

 Brenthis amathusia abundantly, B. selene, and Pararge egeria, of 

 dark form, less so, whilst Dryas paphia was just emerging, a male 

 now and again in excellent condition being observed, and Cyclo- 

 pides palaemon, on knapweed flowers, Adopaea lineola, etc., were 

 also noticed. Crossing by the bridge, one finds good collecting- 

 ground all along until one recrosses the Goschener-Keuss again 

 and enters the pine wood. Here, on the flowery banks are 

 lovely Chrysophanus hippotho'e, Heodes virgaureae and Loweia sub- 

 alpina, swarms of Anthrocera lonicerae and A. purpuralis on every 

 flower-head, Polyommatus icarus occasionally, with Cyaniris (Nomiades) 

 semiargus worn and over. Adopaea lineola is worth a word, for, not 

 only are the specimens very abundant, but they are also some- 

 what dark. In the hot sun, on the morning of August 1st, 

 they were in little flocks, -10 to 50, in a congeries, sunning on 

 a (lamp place on the road, or on the damp loess deposited by a 

 trickling .stream. They were in the pink of condition, whilst Adopaea 

 tliaumas was largely over. Hesperia alveus was widely distributed, but 

 rather less common. Here among the tall herbage, too, Stenoptilia 

 pterodactyla was common, whilst a fine Oxyptilus sat quietly on my 

 coat-sleeve; there was plenty of time to box it, I found a box, carefully 

 opened it, popped it over — nothing. The Oxyptilus had flown, nor did 

 ten minutes' sweeping suffice to produce another. A species lost to 

 science, I feel certain !! Perhaps not though, it may have been only 

 pilosellae. A little further along, a low swampy piece of ground 

 covered with flowers, swarmed with insects ; one could have spent a 

 day among them comfortably, and one regretted that time would not 

 allow one to work as one would at home, a field or wood per day. 

 Most of the species here were common to the whole of the valley, 

 perhaps some thirty species altogether, of which a fine banded Brenthis 

 amathusia much pleased me, as also did some female Heodes virgaureae, 

 fine forms with golden ground, and blackish bases to hindwings, but 

 not so intense as com the neighbourhood of Bobbie in the 



Pellico Valley. The females were scarce, evidently only just coming 

 out, for the males, more abundant, were in prime condition, Loweia 

 mbalpina was possibly nearly o\ ' rags, but I got one 



good female; Chrysophanus hippnthn'e was mixei t,
