SATYRUS. 209 



three additional pale spots arranged in a triangle near the tip. 

 On the under side the fore-wings are marked nearly as above, 

 but the spots are larger. The hind-wings are varied with grey 

 and purplish, or reddish, and are marked with a rather indis- 

 tinct row of small reddish-brown eyes, with white pupils. The 

 fringes are pale yellow, interrupted on the nervures. 



The larva is green, pubescent, with yellow or whitish lines 

 on the sides. It feeds on various grasses, especially Tritictim 

 repens, and there is a succession of broods throughout the 

 year. 



This Butterfly is generally called P. egeria (Linn.) in works 

 on British entomology, but this name properly belongs to 

 the South European form, in which the pale yellow or whitish 

 markings of the northern insect are replaced by rich tawny 

 or fulvous. Lang states that, in some places, P. egerides occurs 

 as the spring, and P. egeria as the summer, brood.

Eyes hairy ; antennae with a distinct pyriform club ; palpi 

 with the terminal joint longer than in Pararge ; wings with 

 the costal nervure much thickened, the median nervure slightly 

 so ; hind-margin slightly denticulated. Colour brown ; fore- 

 wings more or less filled up with tawny, and having an eye 

 with one or two white pupils at the tip ; hind-wings with two 

 or three sub-apical eyes above, and a regular series below. 



This is another Palaearctic genus; and species, much re- 

 sembling the European Wall Browns, S. megara and S.
