ARGYNNIS EUPHROSYNE. 79 



are hairy, and arranged as in the other Fritillaries, but 

 they are short. In colour they are black, except the two 

 dorsal rows, which are yellowish at the base and black 

 at the tip. 



As with the rest of the Fritillaries, the anal extremity of 

 the chrysalis (Fig. 68) is very much curved. In colour it is 

 greyish-brown ; it is stout, and has large wing-cases. The 

 two rows of dorsal spines seen in the larva are repeated 

 on the chrysalis, which is keeled and much angled. 



The perfect insect (Figs. 69 and 70) in large specimens 

 expands about if in. across the wings, but it is often very 

 much smaller. The costal margin of the fore-wings is 

 convex, and so is the hind-margin of all the wings, which 

 are rounded, not scalloped. The upper surface (Fig. 69) 

 of the wings is a rich orange-brown, with black markings 

 arranged as follow : On the hind-margin of all the wings 

 at the end of the nervures, is a row of triangles ; within 

 these, but between the nervures, is a second row ; within 

 these again, and between the nervures, is a row of black 

 dots ; still proceeding towards the base of the wings, which 

 is very dark, we find a number of bars joining the nervures 

 in a zigzag manner. On the under-surface (Fig. 70) the 

 ground-colour is much lighter, and many of the markings 

 are repeated, but more faintly, some of them being brown 

 instead of black. Along the hind-margin of the hind- wings 

 is a row of seven silver spots, fancifully thought to resemble 

 a string of pearls, whence the common name, Pearl- 

 bordered Fritillary. Across the middle of the hind-wings 

 is a broad yellow bar, containing in the centre one large 

 silver spot, and there is one more silver spot, triangular in 

 shape, at the base of the wings, making nine silver spots 

 in all on each hind-wing. This number should be noticed, 

 as it forms one of the few marks of distinction between 

 this butterfly and the last, selene. The dark brown markings
