in one of the meadows on the Coronini hill ; probably one of a 

 second brood. 



Pieris napi var. napaa 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. naiJ(B(E 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 rapa 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 Thais poli/xena did not occur at 

 Herculesbad, and was therefore surprised to find that the larvse 

 were quite abundant on the banks of the Cserna just below the 

 town. A species I much wanted was the elusive Libytliea 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. Evidently 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 3000 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. I am afraid, however, something went wrong, for I 

 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-
