PIERIS DAPLIDIOE. 25 



the same as that of the larva, darkish grey spotted 

 with black, and showing subdorsal and spiracular 

 yellowish lines ; the sharply humped keel of the thorax 

 is traversed by a pale yellow dorsal line ; the cincture 

 appears quite sunk into the substance of the back and 

 is only visible over the wing-covers. These last are 

 greyish, having two darker dusky streaks parallel to 

 the hind margin. 



After some days the grey colouring faded to whitish 

 with numerous black dots. By the middle of Novem- 

 ber one of the two pupse had turned black and was 

 dead ; the middle of the abdomen had collapsed, but 

 the other pupa lived and produced a male butterfly on 

 the 14th of June, 1883. (W. B., Note-Book IV, 165.)

Plate III, fig. 3. 



For eggs of this species I am indebted to the kind-

 ordinary pleasure that I have watched its transforma- 

 tions ; for the insect has always been a favourite of 

 mine ever since I began collecting — now some ten 

 years ago. 



The eggs seem to be deposited singly; in shape they 

 are cylindrical, very long, standing erect on end, the 

 upper end coming to a point, which is curved a little 

 to one side (reminding one somewhat of the shape of 

 a cucumber), ribbed longitudinally — about four ribs 

 appearing in any one view; colour a glistening yel- 

 lowish-white. 



The larva when full grown is about three quarters 

 of an inch in length; head globular, rather smaller 

 than the second segment ; body cylindrical, tolerably 

 uniform in bulk, but tapering very gently towards 

 the tail; anal flap terminating squarely, and under 

 it two very small blunt points appear; the skin
