THE GENUS PERGA. 36S' 



Epinephele janira var. hisjmlla, Hiib. — Extremely ' abundant up to 

 2500 feet; replacing type and somewhat larger, but not so large as some. I 

 have from Greece. E. ida, Esp. — Common at Ajaccio end of June. 



Ccenomjmpha paviphilus, L. — Generally distributed. C. pamphilus var. 

 hjllus, Esp. — Appearing commonly at Ajaccio as we left ; in this case, pro-- 

 bably the form assumed by the second brood of the type. C. corinna, Hiib. 

 — Quite the commonest butterfly at Vizzavona on our arrival ; not so 

 common lower down. 



Sjnlothyrus althcece, Hiib. — Occurs sparingly from sea-coast up to about 

 2500 feet. 



Syrichthus malvce, L. — Similar distribution to the foregoing. S. sao 

 var. therapne, Ramb. — A handsome bronzed form, not at all common, and 

 hard to take from its metljod of flight and assimilation of colour to its sur- 

 roundings. Impartial in its choice of climate; for at Vizzavona, above the 

 hotel, some score or so of specimens had already been taken in May by Mr. 

 Raine. They were still flying there in a more or less battered condition 

 up to the middle of June ; and on the 25th the second brood was already 

 in full flight at Ajaccio, 4000 feet lower. 



To summarise briefly the result of our observations : — There 

 are five good species, \iz., P. hospiton, A. elisa, S.neoniyriSf 

 E. nurag, and C. corinna ; and four varieties, viz., E. tagis var. 

 insularis, S. semele var. aristceus, P. megcera var. tigelius, and 

 S. sao var. therapne, peculiar to the Islands of Corsica and 

 Sardinia ; and of these nine we may congratulate ourselves on 

 having taken eight, E. nurag alone evading our observation. Out 

 of the thirty-eight European genera, only nineteen — ^just one- 

 half — are credited to Corsica. The important families of Thais, 

 Pai'nassius, Melanargia, Erehia, and Hesperia, are entirely unre- 

 presented ; and when those gentlemen who lingered some time, 

 after us have made out their lists, it will probably be found that 

 the number of species falls far short even of those comprised 

 within the British Isles. 



My notes of Heterocera, I regret to say, are far too meagre to 

 be worth recording, and I can only hope that others have been 

 more observant.
