ARGYNNIS EUPHROSYNE. 77 



is dark brown, and the spines are yellowish, some of them 

 tipped with black ; the claspers are dingy red, and the 

 head and legs black. 



The chrysalis (Fig. 65), which is attached to the food- 

 plant, is similar to that of euphrosyne and brownish in 

 colour. The abdomen is abruptly curved, and has two 

 rows of short projections representing the subdorsal 

 spines of the larva. 



The imago (Figs. 63 and 64) is similar in shape to 

 euphrosyne, and so closely resembles it on the upper 

 surface that for purposes of identification reference had 

 better be made to the under-surface only (Fig. 64). There 

 the ground-colour of the fore-wings is orange-brown, 

 except at the tip, which is yellow, marked with a rather 

 large patch of dark brown ; the rest of the markings 

 resemble those of the upper surface, but are fainter. On 

 the hind-wings there is the row of silver spots along the 

 hind-margin. Within these is a broad dark brown band, 

 interrupted in the centre by a yellow patch. This band 

 contains a row of spots as on the upper surface. Next 

 comes a band of pearly-white spots, interrupted in the 

 centre, then some dark brown, followed by the yellow 

 band of euphrosyne, containing three pearly-white spots ; 

 then follow some more dark brown patches, interspersed 

 with several pearly spots. There are thus almost twenty 

 pearly spots (scarcely silver), instead of the nine in euphro- 

 syne. The sexes are similar. 



A. euphrosyne, Linn. (Pearl-bordered Fritillary) (Figs. 

 67 to 70), is the commonest of the Fritillaries and one 

 of the earliest to appear upon the wing. It is smaller 

 than latona, and much smaller than paphia, aglaia, or 

 adippe, but in the markings of the upper surface resembles 

 them all very closely. Though in general a wood butterfly, 

 like most of its kind, yet it roams abroad, and may be
