272 THE ENTOMOLOGIST. 



there are in it two examples taken in Bulgaria by Mr. H. J. 

 Elwes, and labelled var. obscarior, Seitz, which resemble the 

 Herculesbad form, except that in them the ground colour is 

 somewhat whiter, and the dark markings more extended on the 

 wing surface. I presume the Herculesbad form should therefore 

 be called intermedia. 



The only other things worthy of note taken on this day were 

 a pair of Chrijsophanus thersamon and an example of Pi/rgus 

 orhifer, in good condition, larger and darker than my Budapest 

 specimens. 



Last year, at the end of June, worn females of Thecla acacice 

 were abundant flying round some blackthorn bushes, which, on 

 my visit this year, I beat vigorously for larvse ; the only larva I 

 succeeded in finding, however, came out as an imago of T. pruni 

 on May 30th. Apparently the larvae of T. acacice had pupated 

 at the time of my visit. 



Parnassius mnemosijne was abundant about a couple of miles 

 up the Cserna Valley, at an altitude of about 300 ft., surely a 

 very low elevation for this butterHy. The form was similar to 

 that occurring at Budapest; that is to say, with small very dark 

 spots. Fine large Nomiades cyllarits, with an expanse of 36 mm., 

 were seen here and there, and the ubiquitous Callophrys riibi 

 flitted about with occasional Brentliis euphrosi/ne, local and not 

 common. 



I made an observation that somewhat puzzles me. Last 

 year, in one small dingle, and there only, I came across a few 

 rather worn but unmistakable examples of Eceres alcetas (coretas). 

 This year, bemg six weeks earlier, I looked in this place for 

 fresh specimens, and what I did get was three perfect male 

 Everes argiades. I have been told that in Hungary these 

 species, or forms of one species, are mixed up, and occur in the 

 same locahties, and my observation seems to confirm this view. 



An ascent of the Domogled on May 19th was, from an 

 entomological point of view, singularly barren. One would have 

 expected to meet with Erehia medusa var. psodea, and other 

 species ; but with the exception of half a dozen specimens of 

 Papilio machaon, the peak was entirely devoid of butterflies. On 

 the way up, at the well-known Quelle, I netted a fine Ncptis 

 aceris, and saw plenty of Pieris napi and Paran/e egeria var. 

 egerides, and some Euchloe cardamincs. 



May 21st found me back in the Promontor Marshes. Chryso- 

 phanus thersamon was getting passe, quite seventy-five per cent. 

 of those taken showing defects of one kind or another. Plebius 

 argus was abundant and perfect, and a male of the fine Budapest 

 form of P. argyrognomon was taken. I captured one Melitaa 

 trivia by no means perfect. Lyccena astrarche was abundant. 



We spent May 22nd at Szada on a visit to Baron Vecsey. 

 The day was sunny, but butterflies' were scarce. The Baron
