CHRYSOPHANUS PHL^AS. 93 



smooth, but the thorax and abdomen are covered with 

 a short bristly pile of pale flesh-colour, only visible 

 with a strong lens. (W. B., Note-Book III, 118.) 



On the 11th of August, 1876, I received from the 

 Rev. J. Hellins seventeen eggs of this species laid with 

 others most freely on Bumex acetosella by a female in 

 captivity. The egg is a good size considering that of 

 the butterfly, it is circular in shape, rather flattened, 

 though convex, of a light cream colour, very coarsely 

 reticulated with whitish raised net- work. These eggs 

 became greyish on the 14th, and on the evening of the 

 15th three of them hatched, and the others the next 

 day. The young larvae were not at all onisciform ; 

 they had their small heads well in front of the second 

 segment, the body thickest at the third, fourth, and 

 fifth segments, from thence slightly tapering to the 

 rounded anal end. 



In colour they were rather a dingy pinkish green, 

 with a darker dorsal vessel, just visible, and on each 

 side of the back one row of fine and longish black 

 hairs. The larva is sluggish, though it occasionally 

 eats holes through the leaves, it more generally makes 

 a little channel on the under surface just the width of 

 its body, and about its length, so that the larva lies 

 sunk in this channel about on a level with the surface 

 of the leaf. It then either quits this to make another 

 similar hollow in which to rest, or else it continues to 

 lengthen the channel already made always keeping to 

 the under surface of the leaf, eating the green cuticle 

 there, which is much thicker than that on the upper 

 surface of the leaf. 



On the 21st the larvae were very light greenish in 

 tint, a little thicker than before ; by the 24th they had 

 all moulted, and were again a little thicker and more 

 uniform in bulk than previously; the most forward 

 individual one-eighth of an inch in length, already 

 showed a distinct darker dorsal line, rather brownish 

 on its light green skin ; four other longitudinal faintly 

 darker lines appeared on either side, and between
