BUTTERFLIES OF HUNGARY AND AUSTRIA. 283 



P. thersamon, Esp. — Fairly common on the marsh ground below 

 the Kammerwald, and other localities in the neighbourhood of Buda- 

 pest, in August, but some of the specimens were rather worn. I also 

 took it near Kavaran Szakul, at the end of July, where it was much 

 more worn ; possibly the end of the first brood (?). 



P. dispar var. rutilus, Wernb. — A very small form of this butterfly 

 was common round Kavaran Szakul at the end of July ; near the 

 Kammerwald, in August, most of the specimens were much larger. 

 I also took one male in the forest of Szaar, in June. 



P. alciphron, Rott. — At Isaszegh, about fifty kilometres from Buda- 

 pest, on June 2nd, in one particular spot on the borders of a wood, 

 I took several very fine male specimens in perfect condition, and a 

 week later, at the same place, the females were also out, but much rarer. 

 This butterfly also occurs in the Cserna Thai, near Herkulesbad, but 

 it was practically over by the time I got there, both this year and last. 



Lycana amanda, Schn. — I took two males on June 14th, at Szep- 

 Juhaszue, near Buda-Pest, and Herr Aigner took several others, also 

 males. I did not see a female. 



L. meleager, Esp. — This most beautiful butterfly occurs more or 

 less commonly in every locality I visited in Hungary and Austria ; the 

 females, however, are rare. The whole of the month of July is its 

 time of appearance, and good specimens are still to be met with in 

 August. 



L. iolas, 0. — This "monster blue" occurs abundantly in Farkas 

 Volgy the last fortnight in July; but when I was there in August it' 

 was quite over ; I only saw a few specimens, and they were too much 

 worn to be worth taking. It looks as large as M. galatea when on the 

 wing. The larva is to be found in the seed-vessels of Colutea 

 arbor esc ens. 



L. avion, L. — In Mehadia this is one of the commonest of the 

 " blues" ; I also found it at Kavaran-Szakul, where I took one speci- 

 men of the var. obscura, Frey, but it was not so dark as the Swiss 

 form. I may here add that all the commoner species of this and the 

 preceding genus, such as P. dorilis and phlaias, L. icarus, damon, orion. 

 argiolus, corydon, &c, also occur throughout Hungary with the usual 

 prolific abundance. 



Libythea celtis, Esp. — This is a butterfly that seems to have a very 

 wide range, but never to occur in any abundance. Out of the four 

 specimens I have in my collection, one is from Granada, in Spain ; 

 one from Aix-en-Provence, in France ; one from Sondrio, in North 

 Italy ; and one I took last year at Herkulesbad, — the only one I ever 

 saw there. 



Apatura iris, L., A. ilia, S.V., and var. clylie, S.V. — Any entomo- 

 logist desirous of seeing the Apatura reigning supreme must visit the 

 Rohrwald, near Spillern, about twenty kilometres from Vienna, the 

 first fortnight in July. I shall never forget what a sight it was ; the 

 pathways through that magnificent forest were literally swarming with 

 butterflies of this genus, clytie being by far the most numerous, while 

 the typical ilia was comparatively rare. Upon making enquiries of a 

 local entomologist I chanced to meet, he assured me that this profusion 

 of insect life occurred iuvariably the same at this season of the year,
