SATYRW.E. 20; 



witli black at each nervure, so as to give all the wings a 

 scalloped appearance. Female similar, slightly larger, with 

 the submarginal ocellated spots of the hind wings often 

 more distinct, and the pale blotches proportionately a little 

 larger. 



Under side of the fore wings with the markings as above, 

 but the dark portions towards the costa strongly dusted with 

 white, and towards the apex and hind margin with yellowish- 

 white : or with all the dark portions grey instead of black ; of 

 the hind wings with the markings also placed as on the upper 

 side, but appearing somewhat different ; the dark portions 

 being, in the male, grey edged with black lines, rather indis- 

 tinctly towards the hind margin, but with dark nervures ; in 

 the female ochreous mixed with grey, with darker edges, and 

 the pale portions pale primrose. In both sexes the sub- 

 marginal row of ocellated spots is visible, and the outer 

 margin of the. dark band in which they lie is sharply zig- 

 zagged. 



Variation is mainly in the size of the pale spots and in the 

 intensity of the dark ground colour. One form, in which the 

 latter is much extended and very dark, with the spots con- 

 sequently reduced in size, is a predominant local variation 

 in tlie southei'n area of its distribution, and is known by the 

 name of Procida. Specimens of this variety exist in a few 

 of our richest collections, but it is extremely rare here, and 

 apparently confined to the south coast. Of a still more ex- 

 treme form, in which the whole of the wings are blackish, 

 the usual pale markings only indicated by their still blacker 

 surroundings, but a single British specimen is known to me. 

 It was captured in Kent in 1871, and is in the collection of 

 Mr. A. B. Farn. Similar specimens are found in Turkey, 

 and are known under the name of Tiurica. In the opposite 

 direction, variation does not seem to go so far, as no purely 

 white specimen is known ; but one taken near Gravesend by 

 Mr. J. P. Barrett has the whole central area of all the wings 

 broadly white except the nervures, the only black colour
