212 BRITISH BUTTERFLIES. 



very abundant on Mt. Pelerin, with Agriades thetis, Cyaniris semiargus, 

 etc. ; we found it also on the wooded banks between Andermatt and 

 Hospenthal, and on flowery slopes in the Goschenen-Thal. It occurs 

 throughout Ticino, and above Piotta, and in the Piottino Gorge, 

 appeared on the banks with a crowd of other interesting species, 

 among which the " blues " were represented by Agriades coridon, 

 Cyaniris semiargus, Lycaena arion, Polyommatus hylas, Plebeius argus, 

 and Aricia astrarchc. It was also found throughout the Grisons, e.g., on 

 the flower-covered slopes behind Zernetz with Polyommatus amandus, 

 Plebeius argus var. Idlliasi, Agriades coridon, Hirsutina damon, Aricia 

 astrarche, etc., as well as at the runnels by the wayside far' up in the 

 direction of the Ofen Pass, where, in one place, on the banks of a 

 stream, a number of tiny water-rills oozed out, making little wet 

 patches, that crossed a track that indicated a short cut up the valley, 

 and at these damp spots all the " blues " of the valley were assembled 

 — Polyommatus eros, Aricia donzelii, and Agriades thetis, as well as 

 the species already mentioned. In the Roseg-Thal it haunts the 

 steep flowery banks with Polyommatus eros, whilst in the marshy 

 bottom near the entrance to the valley, Plebeius argyrognomon and 

 Agriades coridon appear to be its chief companions. It occurs through- 

 out Austria and Germany, in similar localities to those of England in 

 the plains, and to those of Switzerland in the mountain- valleys, and is 

 mentioned by Dadd as being found on the limestone hills, near 

 Eiidersdorf, as on our own chalkhills, whilst in the Bavarian Alps, 

 near Obersdorf, it occurred on the riverbank at a spot where the river 

 had formed an extensive sandbank overgrown with willow and other 

 bushes, flying with Lycaena arion, Cyaniris semiargus, Agriades thetis, 

 Cupido minimus, Plebeius argus, P. argyrognomon, etc., at the end of 

 June, also in the Oythal, at the junction of the Oy and Trittach, on a 

 sunny bank with an abundance of the same and many other species, 

 on the lower parts of the Seealp, a gradually rising slope leading to 

 the Nabelhorn, as well as in the lower alpine meadows on the side of the 

 Solleneck, with Krebia melampus, Colias phicomone, ( 'oenonympha iphis, 

 ( '. satyrion, etc. It is found in very early spring in the Yal d'Ombla, in 

 Hercegovina where the vegetation is much like that of the Italian 

 Riviera. It occurs also on suitable ground throughout Corsica and 

 Sardinia, a fine race being found on the waste ground about Ajaccio, as 

 well as on the railway banks near Vizzavona. In northern Italy, its 

 habitats are just like those of Switzerland, and Wheeler mentions it as 

 occurring in the Apennines in the plain below Assisi, on the outskirts of 

 the meadows of vetch, with Plebeius argus, Hayivardia telicanus, Melan- 

 argia galatea, etc. He also took it throughout the Abruzzi, in plain 

 and mountain, from 1200ft. -4200ft., in abundance at Subiaco, on the 

 site of Nero's Villa, and in Home in the gardens on the Palatine 

 surrounding the ruined Palace of the Caesars. Its habitats in 

 Spain are equally varied ; Mrs. Nicholl says that it occurs in 

 the wooded park outside the palace of the 1 Alhambra at Granada, 

 and on the steep slopes behind the palace, in hollows overgrown 

 with cistus, broom, and lavender; at Gibraltar, it occurs on the 

 Bock (Walker). Assmuss says that it occuis throughout the Moscow, 

 Kaluga, and Tambov Governments of Russia, in wooded districts and 

 in gardens. In Bulgaria, Mrs. Nicholl notes it as being found in
