BUTTERFLIES OF HUNGARY AND AUSTRIA. 285 



outskirts of a wood, and I believe I saw one or two others flying high 

 up on oak-trees the same day. But when I again visited the locality 

 in August all signs of it had disappeared. 



Melitcea maturna, L. — Fairly common in a limited range, at one 

 part in the forest of Szaar, on June 5th, but several of the specimens 

 were already rather worn, Later on, in one of the forests near 

 Herkulesbad, I also found one or two, but these were very much the 

 worse for wear. 



M. cinxia, L. — The female specimens at Szaar were more or less 

 paler in the ground colour, with the black markings very broad and 

 distinct, and a strong inclination to olive-green on the basal half of the 

 fore wings. 



M. phcebe, Kn. — Always a most variable insect ; occurring in 

 every locality I visited. In the Cserna Thai the females had the 

 ground colour extremely pale in parts, and the black markings very 

 broad. 



M. trivia, S.V. — This year, for the first time, I became personally 

 acquainted with this little butterfly, by no means one of the least 

 difficult of the Melitcea to distinguish and classify, as it varies very 

 considerably both in size and colour. In the forest of Szaar, in June, 

 I took a male of medium size, of which the ground colour in parts was 

 very pale. At the top of a high mountain called Hunka-Kamena, on 

 the frontier between Hungary and Eoumania, I again came across 

 trivia, but so sparingly that I only succeeded in netting two specimens, 

 one of which was a female of such huge dimensions, and so darkly 

 marked, that had I been at Sarepta, in Eussia, I should have con- 

 sidered that I had taken the var. fascelis, Esp. But at Farkas-Volgy, 

 &c, near Buda-Pest, in August, this species puzzled me yet more; 

 some of the specimens were exceedingly small (I suppose, var. nana, 

 Stgr.), the fulvous varying in tone, and many were scarcely dis- 

 tinguishable from M. didyma var. occidentalis, Stgr., which occurred at 

 the same time and place. 



M. didyma, 0. — This is, I suppose, about the most variable of all 

 the Melitaa. Near Orsova, in June, the females appeared all to be of the 

 var. meridionalis, Stgr. ; also occasionally at Herkulesbad, some fifteen 

 miles away, but much less markedly so. The var. occidentalis occurred 

 with the var. alpina at Farkas-Volgy in August, the former often being 

 extremely difficult to distinguish from M. trivia, though some of the 

 specimens were quite distinct. 



M. dictynna, Esp. — Common in the forest of Szaar in June. 



M. athalia, Bott. — A large, strongly- marked variety, called meha- 

 diensis, is said to occur at Mehadia, but I did not come across anything 

 but the type. 



M. aurelia, Nick. — At Peszer, near Buda-Pest, in June. 



Argynnis selene, S. V. — Fairly common in June ; also euphrosyne, L. 



A. dia, L. — Common throughout Hungary and Austria. 



A. daphne, S. V. — Common at Herkulesbad in June and July. 



A. hecate, Esp. — In the neighbourhood of Buda-Pest in June. I 

 did not observe it anywhere else. 



A. latonia, L., aglaia, L., niobe var. eris, Meig., adippe var. cleo- 

 doxa, 0., and paphia, L., are all to be found in both countries. 



A. pandora, S.V. — Occurs in the Cserna Thai. I saw a few speci.
