123 THE ENTOMOLOGIST. 



Larva unknown. A local species, occurring in mountain 

 pastures at a moderate elevation in Switzerland, Tyrol, Savoy, 

 Piedmont, &c. ; also in the Pj^'enees and Altai. 



Var. eroides, Friv. — The male of this form is larger and more 

 blue than the type. The hind-marginal borders are deeper and 

 more clearly defined, and the spots on tlie hind wings larger. 

 Under side characters are exactly those of typical icarus. My 

 specimens are from South Russia and Pomerania. Both this 

 variety and the type exhibit a shade of mauve when looked at 

 from the side, but the mauve tint is especially noticeable in the 

 Pomeranian examples of eroides. I have no female specimen of 

 this form, but Mr. Kane says* it is " dark brown, with a few 

 orange lunules at anal angle of hind wings." 



Var. ccmdaliis, H.-S., occurs in Syria and Asia Minor. I have 

 two males from the latter country, which respectivel}^ expand 

 0"75 in. and 1*0 in. In colour they closely approach male icarus, 

 but they have rather indistinct linear discoidal spots on fore 

 wings, similar to the examples of eros referred to above. The 

 hind-marginal borders are but little, if any, broader than in some 

 British icarus, and the under sides are exactly as in that species. 

 Dr. Langt describes the female as "dark brown, with a row of 

 small orange spots on the hind wings, and with the bases of all 

 the wings faintly blue." 



Dr. Lang describes two other varieties of eros, viz., myrrlia, 

 H.-S. — " Somewhat like eroides, but much larger and paler in 

 colour, the spots on the under side being proportionately smaller. 

 Expands nearly J '50 in. The female pale brown, with faint 

 hind-marginal bands. Habitat, Asia Minor " ; and var. amor, 

 Stand. — " Size of the type. The male is light blue ; all the 

 wings with a narrow black border. Hind wings with a hind- 

 marginal row of black spots ; fringes white. Under side brownish 

 gvey. Fore wings with a discoidal and with a submarginal row 

 of black sj)ots ; basal spots absent. Hind wings with three basal 



zephyrus and var. lycidas, astrarche, anteros, aud avion. Its situatiou on the inner 

 margin is such that, in conjunction with the first three basal ocelli, it forms a 

 curved series of eyed-spots. ' Occasional!}' the usual third and fourth ocelli are 

 thrown out of line, when the last appears to belong to the central series, and 

 increases the number in this series to eight, or nine if the last spot of central row 

 happens to be a double one.
