SOME SPRING AND AUTUMN BUTTERFLIES OF CANNES. 151 
form in a season, but here we found a brood of this fine form in 
a district quite new to us.” . 
Plebeius (egon) argus.—A large form; scarce. 
Everes argiades, gen. vern. polysperchon.—Rare; April and 
May. Mr. Bromilow (‘ Butterflies of the Riviera,’ p. 32) asserts 
that it is triple brooded. . 
Lampides beticus.—October to January. ‘‘Larve in peapods 
bought in the market for table at the end of October, and in 
November ; ? imported from Algeria.” Mr. Morris’s observation 
is suggestive of a possible, and not improbable means whereby 
“British”? beticus have been conveyed to our shores from the 
Channel Islands, or the warm lower Loire valley, where the 
species abounds, and whence, I believe, garden produce is 
exported. And perhaps it is from this region also that the 
migrations proceed which spread over Brittany. For M. Oberthur 
is of opinion that it is not an indigenous species there any more 
than in Britain, but renewed every year from the south after the 
fashion of Colias edusa and C. hyale. 
Tarucus telicanus.—October to December. Rarely in good 
condition. ‘‘ Boxed a very fine female, just emerged, on Inula 
viscosa, October 17th, 1915.” 
Callophrys avis—Rare. In a recent letter Mr. Morris says 
he has not taken it this year (1916). There were examples in 
the Gieseking (regional) collection. Dr. Chapman, in his mono- 
graph “On Callophrys avis, Chpm.” (‘ Trans. Ent. Soc. Lond.,’ 
1910, pp. 85-106), does not mention Cannes as a locality. The 
food plant at Amelie-les-Bains, Pyr. Or., is Coriaria myrtifolia, 
but this does not grow at Hyéres; and the author surmises, 
therefore, in view of the known haunts of the butterfly there, 
that on the Riviera it affects Arbutus wnedo (loc. cit., 1912, 
pp. 409-411). 
Lesopis roboris.—A few taken in the environs of Cannes in 
1913, and three examples in the Gieseking collection. This 
butterfly appears to be much rarer in the Alpes Maritimes than 
in the Basses Alpes and Hastern Pyrenees, and to belong rather 
to the higher levels; as, for example, St. Martin-Vésubie. It 
may not be generally known, for Staudinger does not give the 
reference, that M. Chrétien, who has worked out so many of 
the life histories of French and Algerian lepidoptera, published 
a detailed account of the metamorphoses of L. roboris in ‘ Le 
Naturaliste,’ vol. xii, p. 102 (1890), with a poor woodcut of 
larve and egg. It has been unfortunately named, for it has no 
more to do with oak than 7’. acacie, a sloe feeder, with acacia. 
It feeds exclusively on ash. 
Zephyrus querciis.—Abundant in the larval stage in the oak 
woods on mountain slopes, but ‘‘ quite 70 per cent. are ichneu- 
moned.”’ 
Z. betule.—Larve beaten in May.
