ARGYNNIS ADIPPE. 67 



head, and black body, finely marbled with dirty greyish- 

 whitish, and a stripe of this paler colour above the legs, 

 the spines all black. By the 7th of June it was half 

 an inch long, the body still black, finely varied with 

 minute faint whitish markings ; and now for the first 

 time the spines were pale ochreous-brownish in contrast 

 to the body. By the 14th of June it was nearly five- 

 eighths of an inch long and stout in proportion, the 

 spines all pinkish- ochreous, thickly branched with black ; 

 head black, and the general appearance of the body was 

 black, though faintly paler pinkish -grey markings 

 could be just discerned as follows : the general ground 

 black, thickly sprinkled with atoms of violet grey ; at 

 the beginning of each segment on the back, in front of 

 the pair of subdorsal spines, was a crescent or semi- 

 lunar mark of unfreckled black, velvety by contrast 

 with the other parts of the skin ; these were divided 

 dorsally by two short fine violet-grey lines, which ended 

 with them ; three lines of the same colour and freckly 

 character ran along the side longitudinally, interrupted 

 only by the spines, and a stripe of the same ran along by 

 the lowest or subspiracular row of spines ; the belly, 

 too, was blackish, freckled with violet-grey; anterior 

 legs black, ventral and anal prolegs reddish-ochreous 

 below, black above ; the mouth reddish ochreous. 



On the 23rd of June this larva moulted and its spines 

 became noticeably long in proportion. I figured it on 

 the 26th, when its length was one inch and an eighth. 

 On removing it at first it was shy and curled up for 

 several minutes, then stretching itself out gradually it 

 set off to run at a pace quite equal to the fastest larva 

 of Arctia Oaja! 



The number of its spines was just the same as in A. 

 Paphia, but the first dorsal pair though directed over 

 the head were rather shorter than the others ; beyond 

 the thoracic segments each segment had six spines 

 except the thirteenth, which had only four ; a lateral 

 spine between the second and third, another between 

 the third and fourth, were the only additions to the
