174 BRITISH BUTTERFLIES. 



good orange lunules on the upperside of all the wings, but are scaled 

 with blue to the marginal band; another $ labelled " Djinina-Sahara, 

 iii. '02 (Mrs. Micholl)," is also of the same type. Specimens from 

 "Tsauritz Entsagautz, Atlas Mts., 9000ft., 4.vii. '01 (Meade-Waldo)," 

 are not of the celina form. The celina $ s in the British Museum coll., 

 are labelled "Klasta, 13. v. '01," " Imentella, Atlas Mts. 5500ft., 7. vii. 

 '01," " Meduna, 29. v. '01 " (also a brown 2 , with bright orange spots, 

 almost exactly of the ab. medon, Esp., form on the upperside), " Wad 

 Moorbey, Kehamna, 5. vi, '01," " Amsmiz, 29. vi. '01 " (also $ s, 

 brown, but small, with bright orange lunules), etc. These were col- 

 lected by Meade- Waldo, and are referred to by Elwes (Trans. Ent. 

 Soc. Lond., 1905, p. 379), who records captures made on May 16th, 

 1901, at Busharin ; July 8th, 1901, at Imentalla ; July 13th, 1901, 

 at Sould Jedid ; and August 17th, 1901, at Tangier. Miss Foun- 

 taine remarks (Ent., xxxix., p. 108) that most of the 3 s taken at 

 Sebdou in August, 1904, and at Milianah, in September, 1901, 

 belonged to this variety, and states that she possesses one $ from 

 Milianah with a slight inclination to orange spots on the upperside of 

 the hindwings (see antea p. 140). Most of the Sicilian $ s in the 

 British Museum coll. have a strong tendency to this celina form, and 

 are, in many cases, the specimens mentioned by Zeller (infra), but a 

 fine series of both sexes from Taormina, taken at the end of March, 1905, 

 by Chapman, are not of this form, but are precisely like the specimens 

 already referred to as occurring in Morocco and Algeria in very early 

 spring, in both sexes, suggesting that the form celina occurs only as 

 an aberration in the vernalis-meridionalis emergence, the form celina 

 being really the usual aestivalis representatives of the meridionalis race. 

 Fletcher seems to have come to the same conclusion about the 

 specimens in Malta, as he remarks (Ent., xxxvii., p. 316) that the 

 spring (March to May) examples are fairly typical, although the 

 blue is generally of a more brilliant hue than in Northern European 

 examples, and in the £ s the blue markings are restricted, whilst the 

 ab. arcuata is not uncommon ; the form celina, Aust., he adds, 

 occurs in the vernal brood as an occasional aberration of the J . but 

 all the summer (June onwards) examples are referable to this form. 

 Oberthur notes (Etudes, vi., p. 50) that examples of P. icarus were 

 sent to him from Sidi-bel-Abbes in the spring of 1879, and from 

 Sebdou in September, 1880, that the spring specimens were smaller 

 than the French, the blue tint of the $ s more violaceous, not 

 transparent, and the black border very narrow ; the ground-colour 

 of the underside of an uniform grey and the fulvous portions some- 

 what faint. The only spring ? was analogous with Aijriades thetis 

 (adonis) var. ceronus. The summer form differed from the spring by 

 its smaller size, and less opaque violaceous tint, allowing the spotting 

 beneath to be seen through. Comparing the seven specimens sent by 

 Austaut with those from other localities, he remarks that celina, 

 at first sight, differs from P. alexis of France, but comes so near 

 examples taken in June at Cordova in the wide and warm valley of 

 the Guadalquivir, that it is impossible to find any appreciable differ- 

 ence between the Andalusian type and that of Sebdou ; the form taken 

 at Cordova varies somewhat, however, as elsewhere, and, besides the 

 examples identical with summer celina, he notes larger specimens 

 similar to others from the Sierra Nevada and Rome, which, in turn,
