COLLECTING NOTES. 41 
of this year, there are [ believe two errors, which I feel I must not let 
pass unnoticed. I refer to the statements contained in paragraphs 24 
and 39, and in the first I refer only to the record of Lac Lioson. 
Mr. Fison’s information on the butterflies from that place was, I 
believe, entirely gathered from Major Holland and myself. We had 
made two excursions to the Lac (the month and year named in the 
“‘ Notes’) from La Comballaz, where we were staying. We neither 
took nor saw Parnassius mnemosyne anywhere, but we caught seven or 
eight Parnassius delius g sat the Lac, and of the five in my possession 
the spots are normal. At the latter end of August or early September 
I had much pleasure in making the late Mr. Fison’s acquaintance at 
the Beau Site Hotel, Aigle, where we both remained for some weeks. 
During that time he, with his unfailing kindness, went very carefully 
through our summer’s catches, and this being our first season with 
butterflies they were consequently rather numerous. The entry found 
in his notes is evidently a mistake for P. delius. 
Regarding paragraph 39, Brenthis pales var. arsilache, Mr. Fison 
looked long and interestedly at the B. pales captures. He hesitated to 
name them arsilache, but eventually labelled mine so, at the same time 
expressing doubts. I later found this to be a mistake on his part, at 
least as regards mine. Mr. Fison I know had wished to try himself 
for arsilache at Lac Lioson, but he never got there. This certainly 
looks as though the arsilache impression was strong in him, and rather 
leads me think Major Holland’s series may have approached that 
variety. However these cannot be referred to now, as he is at 
present in British Hast Africa. If altitude were a deciding 
factor they would not occur at Lac Lioson, which is 5,000 feet 
above sea-level at least, and perhaps considerably more. ‘Twice that 
summer it had even been my desire to revisit the Lac to search especi- 
ally for P. delius, and to examine again the B. pales. This oppor- 
tunity did not arise till eight years later, when I went up to La Com- 
ballaz on August 4th, 1913, hoping to have a few days at Lac Lioson 
and its neighbourhood. The next day opened badly with lowering 
clouds, which delayed the start, but a very strong wind getting up the 
sky cleared, and I eventually had a short, but successful day consider- 
ing the difficulties of collecting ina raging wind. On reaching my 
destination (a two hours’ climb) my first quest was for P. delius, but 
only one worn specimen put in an appearance. I next turned my 
attention to the Hrebiae which were flying locally in fair abundance. 
My first take was an /rebia eriphyle. This fly and EH. pharte 
had a little district almost entirely to themselves. One had to 
go round to the other side of this little knoll to find flying F. euryale 
and H. manto together with B. pales. H. eriphyle was fairly common, 
about two thirds being worn, but I secured fifteen good speci- 
mens, three being gs. KH. pharte was in better condition and more 
numerous, and a nice little series of 22 were taken with spots on fore- 
wing varying from very small to a well defined band. Only one 9 
was seen and taken. I also gathered a short series of both H. manto 
and HH. ewryale in fresh condition. b. pales were scarce, ten gs and 
one @ only were netted, all very distinctly type form, having no or 
next to no black markings on underside forewings. 
Of course H. eriphyle was the catch, and my hopes of paying them 
further attention the following day were dashed by the break up that
