ARGYNNIS PAPHIA. 63 



prolegs holding on to the thinner silk layer spread 

 before the tuft, but the head and anterior legs quite 

 free from it ; thus it remained for nearly five hours, 

 and then suspending itself by the anal prolegs only, it 

 changed to a chrysalis on the 9th of June. 



The full-grown larva measures from about one and 

 a half to one and five-eighths of an inch in length and 

 is in proportion rather stout. The broadish head has 

 the lobes produced angularly on the crown by project- 

 ing tubercles, with stout pointed hairs, the ocelli 

 prominent ; the second segment wider than the head, 

 and the bulk again increasing to the fifth, decreasing 

 again from the tenth to the thirteenth ; the spines are 

 in three rows on either side, bulbous based, pointed, 

 and branched with finer hair-like spines of varying 

 lengths ; in position they are subdorsal, lateral, and 

 subspiracular, six on a segment, except that the thir- 

 teenth has only four spines, and the three thoracic 

 segments have on their sides only two spines, and these 

 placed on the segmental divisions laterally, i.e. one 

 between the second and third, and one between the 

 third and fourth segments. As some compensation, 

 however, the first pair of subdorsal spines, as already 

 noted, are of extra length, with blunt tips, and directed 

 over the head, and there are also on each side of these 

 segments from three to five wart-like tubercles, each 

 bearing a pointed bristle ; similar bristled warts, in a 

 transverse series, are seen on the belly of the fifth, 

 sixth, eleventh, and twelfth, and the intervening seg- 

 ments have a longitudinal row of four or five just above 

 the outside of each ventral proleg. 



The colour of the head and its numerous hairs is 

 black and glistening, with a marbling of pale yellow 

 on the crown, upper lip ochreous. Down the whole 

 length of the back are two stripes of brilliant yellow, 

 rather inclining to ochreous and sulphur at either end, 

 separated only by a black dorsal line ; these stripes are 

 still more conspicuously relieved by a black, velvet - 

 like bordering of markings, broad and unbroken, as a
