hind wings, except the red spots, which are as usual. A 

 very handsome variation is figured in the Entomologist, vol. xv. 

 p. 49, in which the silver spots are large, but confined to 

 the basal portion of the hind wings ; it also is strikingly 

 melanic, the fore wings above and beneath, and the hind 

 wings above, being blackish for three-fourths of their length, 

 except one red spot and two or three red dots and streaks 

 on the fore wings. Another, figured on the opposite page, 

 has the entire upper side clouded, between the nervures, with 

 blackish, except the same red spots, and the silvery spots of 

 the under side mainly collected into a grand blotch, occupy- 

 ing the basal third of the wing. (By some oversight this 

 figure is called Ar/laia.) A somewhat similar example in 

 Mr. Webb's collection, a female w-ith the silvery colouring 

 collected at the base, has three spots near the anal angle, 

 instead of silvery, of a steely black ; its upper side has the 

 central portion of all the wings black. Mr. Herbert Gosshas 

 a magnificent male, from the New Forest, in which the spots 

 of the central row in all the wings are of three times the 

 usual size ; and a female somewhat similar. Mr. S. Stevens, 

 one in which the spots of the upper side are strikingly 

 elongated ; auother with the whole of the fore wings heavily 

 clouded with dark brown ; and a third in which the whole 

 ground colour is clear silvery white. Occasionally specimens, 

 otherwise ty{>ical, have the marginal markings of the under 

 side partially obliterated, or, on the other hand, have the 

 rust-red spots strikingly large, so as almost to colour the 

 whole band. 



On the wing throughout July. 



Larva, IJ inch long, with two short branched spines on 

 the second segment, pointing forward; the following segments 

 with two, six, or four spines, also branched. Deep reddish- 

 ochreous, finely freckled with pinkish and black ; dorsal line
