HUNGARIAN AND AUSTRIAN BUTTERFLIES IN 1910. 271 



scent the air for many yards around. Altogether I do not 

 remember ever wandering in more delightful woods. 



Driving from Orsova, a distance of twenty-seven kilometres, 

 we did not reach Herculesbad much before noon, and with un- 

 packing and lunch, I was not fairly started on my way up the 

 Cserna before two o'clock, too late on most occasions for much 

 hope of meeting with many butterflies. On this day, however, 

 I was in luck ; the day previous there had evidently been a 

 heavy fall of rain, and the road was still damp, with puddles in 

 places ; at most of these, Neptis aceris, in twos and threes, in 

 most perfect condition, was drinking. I selected my specimens, 

 for iV. aceris, even when newly emerged, is apt to be chipped or 

 rubbed, but, after allowing for rejections, by four o'clock I 

 mustered thirty perfect in all respects. Last year, a month 

 later, I had to work hard for a whole morning to get half a 

 dozen battered examples. 



Last year I recorded in 'Entomologist' (xlii. p. 274) certain 

 specimens of Picris rapa from Herculesbad. After considerable 

 trouble I find, thanks to the Eev. G. Wheeler, that these are 

 not Pieris rapes, but P. manni var. rossii. They impressed me 

 at the time of capture as something different from any forms of 

 P. rapce I had ever seen, but I could not then identify them as 

 anything else. P. manni is at Herculesbad, as I understand is 

 the case elsewhere, purely a woodland species, feeding, no 

 doubt, on one or more of the numerous Cruciferre which abound 

 amongst the undergrowth. It is most abundant at the level of 

 the road, but one or two specimens were netted at an altitude 

 of quite one thousand feet above it. The spring brood was well 

 out at the time of my visit, but was not very abundant. The 

 tips of the wings and spots are not so dark as those of the 

 second brood, which are var. rossii. A fine form of Leptosia 

 sinapis, with strongly marked under sides, was abundant at the 

 puddles in the road. Polyommatus orion var. ornata was just 

 emerging. Nemeobius liicina, very large and ranging up to 

 38 mm., flitted about the glades a mile or so above the Bad. 

 The spring brood of Pieris napi was also abundant, the females 

 much suffused on the upper sides with grey; and amongst other 

 species observed in the Cserna Valley were Papilio podalirius, 

 Gyaniris argiolus, and Pararge egeria var. egerides ; all of them 

 frequent. 



A visit to the Coronini the next day, May 17th, was not 

 remarkable for the number of specimens seen or captured. 

 Amongst other species, Melitcsa cinxia, with the tawny form of 

 the male usual in South Europe, and a particularly fine female, 

 with ground of wings pale straw colour, all the dark markings 

 on upper side more pronounced than in the type, and a conse- 

 quent reduction in area of ground colour. I find on comparing 

 these with the series in the British Museum Collection that
