80 AEGYNNTS EUPHEOSYNE. 



sions, about an inch long and rather thick when in 

 repose, but when stretched out and walking one inch 

 and a quarter in length. As it approached its full 

 growth the whitish lateral stripe became more and 

 more visible, and appeared divided into two by a 

 blackish rather interrupted line running through it 

 from the fifth to the anal segment ; faint indications 

 appeared of a greyish subdorsal line, especially at the 

 segmental divisions when stretched out, and the black 

 dorsal stripe was also made visible by its edging of 

 greyish ; the subdorsal spines remained greenish- 

 yellow with black tips and branches to the last, the 

 front pair slanting a little over the head ; the head 

 itself black, and beset with short obtuse black spines ; 

 the lateral and subspiracular rows of branched spines 

 were brownish-black, and all were slanted a little back- 

 wards. 



At the end of the month it seemed rather sluggish, 

 and on May 3rd it disappeared amongst the leaves of 

 the dog-violet which had formed its whole sustenance, 

 with, I believe, only one exception, when I saw it eat 

 out a small piece from a leaf of primrose. 



On May 5th it had changed to a pupa, suspended by 

 the tail to a circular mass of silk spun upon the side of 

 the glass cylinder, hanging about three-quarters of an 

 inch from the earth. 



The pupa, five-eighths of an inch in length, was 

 moderately stout and rather sharply pointed, and 

 curved at the tip of the abdomen, and with a depression 

 next the thorax; the wing-cases long in proportion 

 and dull brown in tint, with two rows of pale greyish 

 dots near their margin ; the spiked processes of the 

 head and the back of the thorax pale greyish ; the back 

 of the abdomen brown, with subdorsal rows of blackish 

 spikelets, bordered on each side by a stripe of pinkish - 

 grey, and near the underside of the abdomen another 

 such stripe. 



The butterfly came forth on the morning of the 23rd 

 of May. (W. B., E. M. M. V, 125.)
