272 [November, 1900. 



As often happens on collecting expeditions, I here became sepa- 

 rated from my friend, Mr. Halse, and I saw him no more until night 

 time. I retraced my steps, and eventually found the road to Lago 

 Misurina. I was now in another valley, and I met with a fresh species, 

 E. (Erne, but, like the other Erebia, it was by no means common. 



Mr. Eowland-Brown, who had been collecting in the neighbour- 

 hood of the Stelvio Pass, arrived at the Hotel (Aquila Nera) in the 

 evening, to our great pleasure. The following days were spent in 

 collecting in different localities, but the results were the same. It is 

 quite evident that Cortina is not a land of butterflies, as, although we 

 bad perfect weather, only about 40 species were observed over an area 

 varying in altitude from, say, 4000 to 6000 feet. 



After remaining ten days at Cortina, we were of opinion that 

 the collecting ground should be changed, and so selected Brenner, 

 being the highest point on the Brenner Pass (4485 feet). The village 

 consists only of a few scattered houses, but the Hotel makes up for 

 the deficiency, being, with its " dependance," capable of holding 

 probably one hundred persons ; notwithstanding this we had some 

 ditficulty in obtaining accommodation. English there were none, and 

 I think we were looked upon with suspicion, certainly, to say the 

 least, we were not cordially welcomed. 



Our first day's experience, July 27th, disclosed the fact that we 

 were in far better collecting ground than at Cortina, at all events for 

 ErehicB and Argynnides. Between the Hotel and the little Brenner 

 See, a distance not much over a mile, we met with six species of 

 Erebia. E. Manto and E. Melampus being in the greatest abundance. 

 The wood which slopes down to the Brenner See w^as a delightful 

 spot, and rich in butterfly life. Here I met for the first time with 

 Argynnis Thore ; it had, however, been out some time, the specimens 

 being much battered. A. Amafhusia, Niobe, Aglaia, and Eicphrosyne 

 were all plentiful. 



July 28th, a hot and cloudless day, we walked up to the top 

 of the Post Alp, a little mountain on the north side of the Pass, the 

 railway station being at its base. For the first hour the zigzag path 

 through the wood was in the shade, and although pleasant for climb- 

 ing, was not conducive to insect life. After leaving the fir trees 

 behind, we found one butterfly particularly abundant, Lyccena Pheretes, 

 of which we secured several females, usually so diflicult to obtain. 

 A grassy slope leads up to the summit (about GoOO feet). It was on 

 this slope that we saw such an abundance of Lepidoptera- — owing in a 

 measure, perhaps, to the perfect day. At the summit Pieris Callidice
