AMONG THE BUTTERFLIES IN CORSICA. 261 



which play alternately at their respective cafes. These are 

 crammed both inside and out ; and the roadway is so tightly 

 packed with human beings that, from one end of it, in the 

 uncertain light, the appearance is that of a compact mass of 

 stationary human heads, so slowly do they move. But I have 

 already trespassed too long with my digressions on the indulgent 

 Editor's patience, and must hasten home. 



At midnight of the 25th, then, my friend Jones and I got on 

 board the packet for Marseilles ; the tree-frogs croaked out their 

 deafening farewell from the Place des Palmiers, and we bade a 

 long " adieu ! " to Corsica with its fascinating people and climate, 

 and natural history. We made one break only in our journey 

 across France, viz., at Avignon, in order to visit the famous 

 Roman viaduct of Pout du Gard, and secure a few of the Mela- 

 nargia lachesis and Gonepteryx cleopatra which so abound there. 



I append a list of the Rhopalocera taken and observed during 

 our visit : — 



Fapilio podalirius, L. — A few at Tattone, 2500 feet, and at Ajaocio. 

 F. machaon, L., and the ab. sphijrus, Htib., in which the black bands are 

 wider and the tails shorter than in the type, occurred sparingly at Ajaccio, 

 but we were rather late for the first brood ; of the ab. aurantiaca, in which 

 the ground colour is of red-gold, I procured one sample from a local 

 collector. Both these forms are somewhat smaller than the type. 

 P. hospiton, Gene. — Very scarce. Three were taken in flowery meadows 

 sloping to the river at Tattone, and one at Corte, 1'200 feet. Food-plant 

 said to be Femda communis, which is plentiful enough by the roadside. 

 After we left Mr. Gemann captured two more, and Mr. Raine took one 

 more and saw three others. 



Fieris brassiccs, L., F. rapce, L., and P. nain, L. — Generally distri- 

 buted ; the latter not so common as the two former, but all large, strongly 

 marked, and varied. P. daplidice, L. — Abundant and fine, occasionally up 

 to 2500 feet. 



Euchloe tagls var. insularis, Stgr. — Tips of fore wings paler than type ; 

 spots on under side greener and very small. Two specimens presented by 

 local collector. Fauly common in March. One fresh specimen, pre- 

 sumably second brood, was taken at Ajaccio in June. 



Leucojihasia sinapis, L. — Common everywhere. Failed to meet with 

 the spring ab. lathyri, Hiib., said to occur here. 



Colias liyale, L. — Two or three solitary specimens observed at 

 Bocognano, 2000 feet. C. edusa, F. — Abundant at Bocognano and 

 Tattone. Mr. Jones took a fine example of the ab. helice, Hiib., at the 

 former place. 



Gonepteryx rhamni, L., and G. cleopatra, L. — When one takes a 

 solitary female, as was my case at Bocognano, it is impossible to say to 

 which of these species it belongs, and I believe no others were taken before 

 we left; but there is no doubt that both species do occur. We were 

 probably too late for the first brood. 



Thecla rubi, L. — Two worn specimens only, at Vizzavona. 



Folyommatus phlceas, L., and the ab. eleus, F., were both well repre- 

 sented at Vizzavona, and both exceptionally fine in form. Many of the 

 former had the beautiful series of blue dots on the inner margin of the
