SOME SPRING AND AUTUMN BUTTERFLIES OF CANNES. 105- 
La Bocca (the Cannes plage) in February, 1907. There are, of 
course, long stretches of wholly unexplored ground on the Medi- 
terranean coast of Spain and France, but the sporadic nature 
of its known distribution yet remains to be elucidated. Almost 
without exception 7’. ballus in Europe is associated with the 
coast. But, if existing records are to be trusted, it extends 
inland at least to Aix-en-Provence and ? Draguignan (Segond, 
‘ Catalogue des Papillons du Var,’ 1853). In Spain it is reported 
also from Grenada; on the Atlantic watershed in South Por- 
tugal at Elvas and Evora, well away from the sea towards the 
Spanish frontier. 
Chrysophanus virgauree-—This, of course, is a summer 
butterfly at Cannes, and, as such, is not within Mr. Morris's. 
ken. I have seen examples captured there by Mr. Warburg, the 
males as fine and even more brilliant than those taken by me at 
St. Martin-Vésubie, where in size the species seems to attain the 
maximum. 
(C. thersamon.—Another of Milliére’s extraordinary finds. He 
records the var., or rather gen. est. omphale, Klug, from St. 
Martin, ‘‘ replacing type,” a mistake surely the more obvious as, 
even supposing thersamon to occur at all up to 4920 ft. west of 
the Alps, there would probably be but one brood, and the tailed 
omphale, as a constant variety, I believe, is invariably of the 
second emergence. Yet we are informed that it is generally dis- 
tributed there, and that omphale “ appears to replace the type.” 
Neither I nor other British or French collector at St. Martin 
have ever encountered it since; and I conclude, therefore, that 
Milliere confused it with C. phleas var. eleus.] 
C. aleiphron var. gordius.—Mr. Morris mentions the capture 
of a few examples at the end of April, and in May, a poor form 
and scarce. Which leads me to think that the emergence at 
Cannes is probably prolonged, and that the later flight is better 
developed. M. Oberthur described the gordius of the Alpes- 
Maritimes as a magnificent race. His examples, no doubt, are 
from the uplands. My own from St. Martin-Vésubie are worthy 
peers of the glorious Digne form. April, at all events, is a very 
early date, or are there two generations here, as elsewhere, with 
C. hippothoé var. rutilus and C. phigas? M. Oberthur considers 
the emergence at Vernet in the eastern Pyrenees at the end of 
May exceptionally advanced. 
C. dorilis.— Not common at Carnes. 
C. phieas.—And in autumn ab. et var. eleus. 
Lycena arion.—Rare. M.Oberthur (‘ Lépid. Comparée,’ fase. 
ly, p. 825) writes that he has received a superb form from the 
Alpes-Maritimes under the name of ligurica. The ground colour 
of the upper side is clear yivid blue, especially in the female ; 
the black spots highly developed chiefly on the upper wings, 
sometimes forming a kind of broad and closely packed cluster of
