274 THE ENTOMOLOGIST. 
in one of the meadows on the Coronini hill; probably one of a 
second brood. 
Pieris napi var. nap~e was abundant everywhere, especially 
in the ravine leading up to the Quelle; the examples were large, 
many of them having an expanse of 55 mm., whilst one expands 
57 mm., and the females were heavily spotted. From ova 
deposited by captured females I reared a few examples after 
my return home; these were var. napee of course, and closely 
resembled their parents. At the higher levels on the first few 
days of my visit I came across a few typical specimens ; evidently 
these belonged to an earlier brood; they were not in good 
condition. 
Pieris rape was equally abundant with its relative, but did 
not, within my observation, extend much above the valley. The 
form was a very handsome one, with pronounced black tips to 
the front wings, brilliant canary under sides to hind wings, and 
heavily spotted females. 
I spent the morning of June 17th on the Coronini hill, but 
did not add much to my knowledge or collecting-boxes, for the 
day was unfavourable and the grass in the meadow had been 
cut. Doubtless earlier in the summer the hill is more prolific. 
I was told at Budapest that J’hais polyxena did not occur at 
Herculesbad, and was therefore surprised to find that the larvee 
were quite abundant on the banks of the Cserna just below the 
town. A species I much wanted was the elusive Libythea celtis, 
which almost eluded me, for although several specimens were 
seen near the town on June 21st, and one was netted, they dis- 
appeared from there mysteriously the next day, and except for 
one taken at the Domogled Quelle on June 22nd I did not see 
another example. Lvidently there was an emergence about 
June 20th, the specimens of which seem to have migrated to 
another locality a day or two afterwards. 
After June 21st all the better insects deserted the roads, and 
I had no option but to work the higher ground. The best collect- 
ing at Herculesbad seems to be centred upon the slopes of the 
Domogled, a mountain which lies south-east of the town, and 
rises to some 38000 ft. above it. Mr. Jones in 1907 having 
made a very successful ascent of this mountain under the 
auspices of a local guide, Nicholas Kolopenza, I thought I could 
not do better for a start than to send for him, and stipulate 
that I should go up the mountain by the road Mr. Jones had 
patronized. Iam afraid, however, something went wrong, for 1 
was taken down the road leading to the station for a mile or so 
until we got to a place where some mining operations were going 
on; here we assaulted the mountain from the south-west, a very 
steep, dry, hot route, on which I did not see a single butter- 
fly I wanted, and by the time the summit was reached I had had 
enough of it. After my experience I should advise anyone work-
