56 THE ENTOMOLOGIST. 



Issoria lathonia. Near the top of the hill one fresh specimen of 

 Pamassius mnemosyne was taken, and Cyaniris argiolus, Pieris 

 rapce, Leptosia sinapis, Gonepteryx rhamni, Coenonympha pa?n- 

 philus were all of frequent occurrence, while a single specimen 

 of Polyommatus orion var. ornata appeared to be the first fore- 

 runner of its generation. 



The following day was cool and inclined to rain, and I spent 

 a long time trying to find the well-known locality near Budafok 

 for the two "coppers," Chrysophanus dispar var. rutilus and 

 C. thersamon, but went a good deal too far beyond the village 

 and missed it, only having a very long walk through most un- 

 promising-looking country, seeing practically nothing until late 

 in the afternoon, when, coming back along the banks of the 

 Danube, I picked up out of a little swampy dell a fresh male 

 C. thersamon, two or three Melitcea cinxia, and a single specimen 

 of Rusticus argus {cegon). The next day was wet, and it was not 

 until the 19th that I was really collecting on the marshy ground 

 which stretches from Budafok as far as and beyond the station 

 of Kamaerardo ; on these marshes and in the adjoining wood I 

 spent many delightful days, nearly always finding something 

 fresh in this splendid locality, though perhaps butterflies were 

 not generally as plentiful as I had expected. During the eight 

 days I spent at Budapest the weather was anything but pro- 

 pitious — only two days were really fine and hot, the others 

 being wet ; moreover, several brilliantly fine days were com- 

 pletely spoilt from an entomological point of view by the 

 tremendously high wind, which made all collecting out of the 

 question. 



However, the 19th ivas one of the perfect days, and I made 

 the most of it, and seldom have I enjoyed a day more ; the 

 valley in which I was collecting was still covered with uncut 

 hay, amongst which flowering-plants of all descriptions grew in 

 profusion ; the willow trees on either side of the little stream 

 which runs the whole length of the valley were covered with 

 emerald leaves, and among them great numbers of very tame 

 golden orioles piped their flute-like notes. Further on, where 

 there is a small swamp, great patches of yellow iris in full flower 

 added brilliant touches of colour. Flying amongst the uncut 

 hay were plenty of newly emerged Coenonympha iphis, with well- 

 marked under sides ; fresh M. phoebe were also common, with 

 occasional Brenthis dia. Sitting on the thyme flowers were fine 

 large Polyommatus icarus males and several R. argus {cegon). 

 Further along Nomiades cyllarus was not uncommon, fine large 

 specimens, though not such giants as those I was to take in a 

 fortnight's time at Herkulesbad ! Here also were odd examples 

 of C. phlceas, several newly emerged Agriades thetis males, and a 

 few Pyrantels cardui, while C. hyale was everywhere abundant 

 and quite fresh. At the corner where the wood joins the 

 meadows I found T. polyxena plentiful, but they were mostly
