108 BKITISH BUTTERFLIES AND MOTHS 



The spiny larva is tawny mingled with black, and 

 with a broad whitish patch on the back of the seventh 

 to twelfth segments ; the head and second segment are 

 black ; the head with two short ear-like projections. It 

 feeds in June and July on elm, currant, hop, etc. 



The perfect insect appears in July and August ; it 

 lives through the winter, and is again seen on the wing-

ARGYNNIS PAPHIA. THE SILVEK-WASHED

 near Huddersfield, York, Scarborough, and Darlington. 



The expansion of the wings is from 2J to nearly 

 3 inches. All the wings are bright fulvous, with black 

 stripes and spots. The hind- wings on the underside are 

 greenish, with the hind margin silvery and with three 

 silvery bands. 



The female has generally a greenish tinge on the 

 upperside, and varieties occur in both sexes in which 

 the brilliant fulvous colour is quite suffused.

The spiny larva is black, with two slender sulphur- 

 coloured lines down the back, and several ochreous lateral 

 streaks; two spines of unusual length project over the 

 streaks ; it feeds on the dog-violet ( Viola canina) at the

The perfect insect appears in July, and continues till
