CYANIEIS SEMIARGUS. 313 



icarus, and a host of larger species ; also on the flat beyond, where it 

 haunted the thyme with Loioeia gordius, Plebeius argyrognomon, Aricia 

 eumedon, etc. It was observed in the marshy hollow at the entrance to 

 the Yal Roseg, with Polyommatus eras, Aricia donzelii, Cupido minimus, 

 Agriades coridon, Plebeius argyrognomon, Aricia astrarche, etc., and yet 

 again on the Albula flower slopes just above Lake Palpuogna, and again 

 on those directly outside the Via Mala (Tutt). Keynes also records it as 

 occurring on the slopes running down to the stream, in the Suvretta-Thal, 

 quite near Campfer. In Austria it is recorded as occurring in the forests 

 and meadows of Bohemia (Nickerl), in June, 1883, it was very 

 common among long grass at the upper part of the valley near 

 Carlsbad (Becher); it is found in meadows and by roadsides, 

 particularly choosing moist situations in Moravia (Schneider) ; flies 

 in forest-glades in Upper Austria (Brittinger); in dry meadows 

 throughout Lower Austria (Rossi); and is common in the plains 

 in Salzburg, but extends up to the Alps (Richter); it particularly 

 loves moist pasture lands, but is also one of the most widely- 

 distributed "blues" in Carinthia, extending up to the higher 

 alpine region (Hofner); in the Tyrol, it reaches from the lower alpine 

 region, to almost 8000ft., occurring all over the Dolomites in the high 

 mountain meadows, haunting the "serpents" of the Mendelstrasse, 

 and the topmost pastures of the Penegal (Tutt); at Brenner the 

 commonest blue, occurring on the I^ostealp, an isolated grassy 

 promontory between higher ranges, approached through firwoods, their 

 slopes at first gay with the alpine-rose, and then followed by mountain 

 moor, morass, and loose stones (Rowland-Brown); whilst above 

 Cortina it was very abundant, flying in company with Albulina pheretes 

 (A. H. Jones). In the Bucovina it occurs in the rich meadows on both 

 sides of the road, leading through a deciduous wood on the north 

 slope of the Cecina Mount near Czernowitz, at an altitude of about 400 

 metres, the species not being often met with elsewhere in the district 

 (Hormuzaki). In Spain it is reported as occurring in the hollows of 

 the hills near Albarracin (Zapater), whilst by the side of a brook to the 

 east of La Granja, where the stream runs through a well-wooded dell, 

 from the pastures above, C. semiargm recurs with a host of other species, 

 particularly above the wooded district (Sheldon), as well as in the dried 

 torrent beds near Alfakar, at the foot of the north side of the wooded hills 

 (Rambur). In south-eastern Europe, in Bulgaria, it occurred in the 

 Rilska valley, on some broken ground, w-here granite blocks had rolled 

 down from the precipices on a sheltered meadow 7 at the foot of the 

 wood, the rocks overgrowm w 7 ith all kinds of flowering weeds, and 

 intersected by a tiny stream forming a sort of natural rock-work, with 

 Scolitantides avion, Aricia eumedon, Ayriades bellaryus, Polyommatus 

 lujlas, P. icarus, etc. ; it was seen also in some wet fields on the slopes 

 of the Vitoch near Sofia, with Aricia astrarche, Plebeius argus (aeyon), 

 Af/riades bellaryus, Polyommatus icarus, etc. ; it was found also on the 

 sandstone hills to the west of Slivno, as well as about halfway up the 

 Drinaca (6650ft.), in a steep meadow with Melitaea aurinia, Cupido 

 minimus, Hesperia alveus, etc., whilst it appeared to be the only blue 

 on the high slopes of the Rhodope, around Samakov, at the end of 

 June, a locality w 7 ith a remarkable growth of ferns and mosses, but 

 with few T Rhopalocera. It w 7 as found in Bosnia, on a plateau on 

 the limestone mountain, Vlasic Planina, near Travnik, at 4500ft.
