settle on a sun-warmed rock, cacalie on flowers and grasses; 
Andromedeé is a much stronger and more active butterfly, while 
cacali@ appeared to be generally on the wane when the latter 
was fresh of both sexes. I am not sure whether the food-plant 
of Andromede is known, but I dislodged one female evidently 
ovipositing on Dryas octopetala, which is common at these alti- 
tudes. Andromede begins to show at about the lowest flight 
of Hrebia lappona (6500-7000 ft.), as I found it about Kaux- 
Bonnes in the western Pyrenees (Entom. xliv. p. 887), of 
which locality, with its sparse flora, ranunculus, myosotis, 
and accidental rhododendron, the Dauphiny habitat is decidedly 
reminiscent (Lépid. Comparée, fase. v. pte. 2, pp. 108-9). 
The morning of the 19th was devoted to the lower part of this 
walk, chiefly under the torrent of the Meije, where there is 
plenty of good collecting ground. The sunny path with 
occasional dripping water attracts swarms of insects of all 
Orders. Hesperia carline males were in perfect condition, and 
among the Lycenids I spotted, on the wing, like a silvery 
P. eros, which species was swarming at the time, a solitary and 
perfect male P. donzeliti. It was a welcome visitor ; I had not 
seen this loveliest of Alpine ‘‘ Blues” alive since I was at Trafoi 
and Cortina fourteen years ago; nor was I destined to see it 
again this year. Two or three fine female H. pharte were 
selected from the many on the wing; H. euryale was now 
commoner than ever, both here and along the river-bed where 
I sought refuge from the prevailing hurricane on the 16th, 
and on the finer 14th. The flora consists almost wholly of 
leguminous plants. As might be expected, therefore, there was 
abundance of Lycenids, chiefly P. hylas and P. escheri. Of the 
former I managed to box a female with the basal and median 
area of all the wings on the upper side suffused with blue (=ab. 
cerulescens, Obthr.). It is the only blue female in my 
collection, for there is apparently in western Europe a far less 
pronounced tendency in the sex of this species to assume the 
male coloration than in the majority of the group possess- 
ing andromorphic females. Other Lycenids of the river-bed 
were P. damon, hardly out; and P. thersites, one or two 
males. 
The Anthrocerids (Zygenide) observed at La Grave are not 
many—A. transalpina, A. purpuralis, A. lonicere and A. exulans. 
Unfortunately I had omitted to provide myself with a résumé of 
Mr. Lowe’s captures, and thus overlooked the locality, a mile 
below the village, where, in conjunction with Mr. A. H. Jones, he 
discovered Melitea deione. On the 21st I left for Le Lauteret.
