SOME OUSEftVATIONS ON MR. MCCLYMONT's CAPTURES. 197 



As a guide to other species thau the Hesperiids which had 

 not been worked out at the time of publication, Mr. McClymont 

 will find M. P. Eondou's ' Catalogue des Lepids. des Pyrenees ' 

 of invaluable assistance. lam sure too that if he will write to 

 the author — Instituteur, Gedre, Htes. -Pyrenees — M. Eondou will 

 be pleased to give him any miorination he may desire about the 

 lepidoptera of this delectable mountain chain. 



Iphidi'ies podaliriKSi. — The type form is replaced l)y var. 

 feisthameln in the Eastern Pyrenees, at least as far north as the 

 plain of Eousillon. Tiie forms described here are gen. rem. 

 iiiiegii and the typical qeu. a^t. 



Pariiassius delins lias never been reported authoritatively from 

 any part of the Pyrenees. Anatole Carteron, who collected at 

 Ceret, not far from Amelie-les-Bains, in the early sixties, and 

 published some diverting and highly unscientific ' Causeries sur 

 I'Histoire Naturelle' in 1868, rightly excludes delius {= jihoehiis, 

 Prun.,) from the Canigou region, but wrongly includes it with 

 apoVo and mnemo^yne in the Hautes-Pyrenees in tlie neighbour- 

 hood of Montlouis and Saillagousse. I venture to suggest the 

 Parnassius captured by Mr. McClymont is one of the forms of 

 <ipollo haunting the district south of Mont Canigou. M. Oberthiir 

 describes and figures the Pyrenean races as var. pgrenaicus — 

 "a polymorpbic race" (' Lepid. Comparee,' fasc. viii, Eennes, 

 1912). ■ 



Among the forms of apollo, especially those figured from the 

 Central Pyrenees, there are some of both sexes superficially 

 resembling delius. In Count Emilio Turati's admirable pauer, 

 " Variabilita del Parnassius apollo pumilus, Stich." ('Att. Soc. 

 Ital. Sci. Nat.,' vol. Ivii, 6 coloured plates, 1918), which the 

 author has mo>t kindly sent me during the last month, on 

 plate iv, delius cervinicolus, Fruhst. c? . from Piedmont (the form 

 I took at Susa in June, 1899), is figured side by side with 

 the form apollo bispupillata, Turati, c? » ^-nd tbey are extra- 

 ordinarily alike ; so much so, that one cannot help the conclusion, 

 long since, I believe, come to by Dr. Chapman, tbat there is a 

 zone not only of intermixture between apollo and delius, but 

 where tlie two species actually interbreed, and the resultant 

 forms apollo x delius, as might be expected, throw back to the 

 ancestral delists. 



Glaiicopsyche lijsinion. — Mr.McClymont's record of an example 

 of this " Blue " in the Pyrenees-Orientales is interesting. M. 

 Oberthiir does not admit it into the French catalogue, though 

 he says he has been assured that it has been taken at Montpellier 

 and Marseilles, though he has never bad authentic proof. Neither 

 he, nor de Graslin, Bellier, or Mr. Elwes, nor any of the later 

 collectors have reported it. Eiihl ('Pal. Gross-Schmett.,' bd. 1, 

 p. 252) cites three French localities — Bayonne, Pau, and Per- 

 pignan. The first two localities may, I think, be rejected. He
