most of my specimens more or less strongly — generally more. Under 

 side upper wings : yellowish grey. Unbroken line of ocellated anti- 

 marginal spots and marginal spots p -shaped, faint and ill-defined ; two 

 discoidal spots, black ocellated white. Under side lower wings : very 

 variable, darker brownish grey to dark brown ; two costal spots black, 

 ocellated white. Outer, margin yellowish-ochre peacock eyes, and 

 iuteriorally white spots ocellated black. Broad white fringes all the 

 wings. 



L. orbitulus var. oberthuri, Stgr. 



Described in Staudinger's Catalogue "major," but I have speci- 

 mens from the Swiss Alps equal in size to those taken by me at 

 Gavarnie and the Lac de Gaube, as figured. Superficially an entirely 

 different insect to pyrenaica, with which it sometimes flies, e.g., at 

 Gavarnie. 



$ . Ground colour of all the wings upper, and under side deeper ; 

 and blackish rather than brown. The discoidal spot on the upper 

 side of the hind wings very much more definite than in the type, 

 which does not occur, according to M. Eondou, in the Central and 

 Western Pyrenees. Under side : in most of my specimens the costal 

 spot on the lower wings is not ocellated, thus suggesting a connecting- 

 link with pyrenaica. 



L. pyrenaica, B. 



$ . Upper wings uniform slaty-blue with faint brownish shading 

 at outer margins. Marginal border sharply defined, and dead black. 

 Discoidal spot dead black, and not ocellated. Lower wings : same 

 coloration. Hardly any trace of peacock eyes ; in most of my speci- 

 mens, none. Under side upper wings : faint dove-grey coloured; series 

 of antimarginal spots, more curved outwardly than in orbitulus, and 

 wanting in some examples between the nervures occupied iuteriorally 

 by the discoidal spots. Marginal spots round. The second in the 

 outer margin duplicated, thus . . but ? constant. Under side lower 

 wings : colour yellowish grey. Trace of very slender black marginal 

 border at anal angle only. One costal spot white without ocellation. 

 Antimarginal spots blotched, and also unocellated. Two or three 

 bright orange-yellow spots on hindmarginal triangular white blotches. 

 Broad white fringes all wings. 



M. Oberthur, in his ' Etudes,' — which are unfortunately in- 

 accessible to most collectors, there being no copy at present in the 

 library of the Entomological Society, — differentiates L. pyrenaica, 

 ? , as follows : — " Pyrenaica, 2 , est toujours en dessus d'un gris 

 blanchatre uni et satine avec un serie submarginale d'eclaircies 

 intranervarales, et un lisere noir marginal tres fin, tandisqu' 

 Orbitulus a le fond des ailes entierement noiratre avec le disc 

 saupoudre d'un semis serres d'atomes bleu argente. De plus 

 dans les deux sexes la serie transversale de points noir intra- 

 nervaraux aux ailes superieurs est toujours moins droite dans 

 pyrenaica que dans orbitulus."
