84 THE ENTOMOLOGIST. 
valley, where on the sides of a streamlet, Brenthis selene, appar- 
ently only recently out of the chrysalis, and one rather worn 
B. euphrosyne were sporting among the wild flowers, while 
Limenitis camilla was netted flying round a bush. Returning to 
the hotel for lunch several fresh specimens of Gonepteryx rhamni 
and some bright Vanessa urtice were secured. I did not again 
visit the summit of the Ballon d’Alsace until July 26th, by which 
time Hrebia stygne had knocked itself to pieces, and EH. ligea had 
taken its place as the most abundant butterfly. On this occasion 
a freshly-emerged female Parnassius apollo was found at rest on 
a flower-head on a steep slope just below the statue to the 
Virgin, which has been erected on the highest point. On July 
4th, Mr. Barraud and I paid a visit to Wesserling, a German 
town, which was reached by coach from Bussang at the head of 
the St. Maurice valley. At the top of the col, at an altitude of 
2410 ft., the road passes through a tunnel, and we emerge in 
German territory. A characteristic feature of the Vosges range 
is that on the western slope the descent to the level of the plains 
is gradual, whereas on the eastern side the declivity is very 
abrupt. This is well seen on the ride to Wesserling, and we 
ran quickly down the steep gradients to our destination. We 
had only about a hour’s collecting at Wesserling, but it proved 
to be very remunerative. Crossing the railway near the station 
we ascended a wooded hill and were soon busy. Never, I think, 
have I seen such an abundance of butterflies, especially of Argyn- 
nis paphia, which was present in countless numbers on every 
bramble bush. Here we got ten specimens of Brenthis daphne, of 
which Mr. Barraud had met with a single example at St. Maurice 
on July 8rd. L. camilla, I. lathonia, A. adippe and its var. cleodoxa, 
M. didyma, and M. galatea were among the species taken. We 
were experiencing perfect weather, and the next day we deter- 
mined to ascend the Ballon de Servance. ‘The path led past the 
spot where a few days before we had discovered LH. ligea and 
close by Mr. Barraud found Hipparchia semele, having lower down 
taken the first specimen of the season of Leptosia sinapis. 
Crossing the heathy slope where the commoner blues and 
fritillaries were sporting in the sunshine, the way next traversed 
the dense pine forest, where no sign of winged life was to be 
seen, but after a stiff climb through the gloom we emerged into 
a sunny meadow, where we were soon hard at work taking 
among other things some rather worn specimens of Chrysophanus 
hippothée. Another short walk through the forest brought us 
on to the military road leading to the fort on the summit. A 
flowery space among the young fir trees was spied, which proved 
to be a veritable ‘‘ butterfly corner,’ and where we afterwards 
spent many pleasant moments in the company of Vanessa 10,
