166 THE entomologist's RECORD. 



the railway banks, where it was more open and sunny, and collected 

 for the remaining four miles to the Morteratsch station. Butterflies 

 were here fairly abundant. Bre)tthis pale^ perhaps predominated, the 

 males were quite normal as to colour and size, while the females were 

 of the var. hh form, the upperside dusted with blackish and the yellow 

 of the underside predominating over the red. Some females were of 

 the ab. nnpaea with upperside shot with purple, but still not of the 

 extreme form of this ab. There was also a tendency to develop 

 spotting on the underside of the forewings in some of the females, a 

 sort of intermediate step to var. a rsila die v^here this spotting is strongly 

 emphasised. One female was a very pale washed-out tint, although in 

 good condition. One example of Brentlns eiiji/iroaj/ne was taken, and 

 this at over 6,000 feet. It was large in size and quite fresh. There 

 were plenty of Krehia ti/ndanis and C. vielavipiis was in some number. 

 The former were the typical twin-ej'e-spot upperside forewing, but the 

 undersides of the hindwings were of a dark inconspicuous gray, devoid 

 of character, the latter with a tendency to the diminution of the 

 reddish patches and black spots ; in one brought home there are only 

 two reddish patches on the hindwings, and these without black dots. 

 Coeiinni/iiipha xatyrion was very common and generally typical on the 

 underside. All the specimens taken had no apical eye-spot on the under- 

 side of the forewings. The males were of the unicolor form. ( 'oenoin/m- 

 pha ip/iis was much worn and only a few were noted. A beautiful Pontia 

 calliilice was taken, nearlj^ to the Morteratsch station. There were 

 plenty of Plchriiis oriiiirixjnonion of the large alpine form ai'tiidion in 

 quite good condition. Albtilina plierftc'swa.s, as usual, in marsh}^ .spots and 

 as usually my luck not in good condition. A Hesperiid was common , which 

 so far as I can see was onl}' Hei^peria alveiis. A specimen of Larentia 

 (■aesiata was of large size and with very clearly emphasised transverse 

 markings. A few plumes were met with but none were taken. Of 

 Anthrocerids only one or two Anthrocera purjmralis {pilosellae) were 

 seen. The little yellow Geometer Acid alia flariolaria was also very 

 abundant here, as was the Tortricid Aphelia avfientana. The flowers 

 noted were Pip-ola rotund i folia, locally common under shade, and 

 plenty of Pirviidcula miliaria, the fly-eating butterwort, on the wet 

 marshy banks. 



At last the station was reached, and the weather changed. The 

 sun gradually disappeared, and collecting was over for the day. My 

 wife met me, and we wended our waj' towards the glacier, and then 

 up the steep zigzag to the level path skirting the western side. From 

 the Chunetta one has a fine view of the glacier, its terminus, and its 

 whole surface for miles. At one's feet are the smooth rock surfaces 

 made by the glacier when it extended further down than now ; on the 

 centre of the glacier lies an unusually wide moraine, and along each 

 side one can plainly see the huge lateral moraines. The path, some 

 five miles, to the Boval hut goes sometimes on the mountain slope, 

 sometimes on the moraine, sometimes over snow even at this time of 

 the year. As we went it got colder, and finally, w^hen we reached the 

 rough steps for the final climb, it began to snow. This made us, after 

 a rest and refreshment, forego our intention to reach the hut, and 

 we turned back. There was an almost complete absence of insect life^ 

 but the patches of colour from the flowers were very pleasing. In 

 many places the rhododendrons were not yet over, and on the moraine
