PIERIS DAPLIDICE. 23 



rather large in proportion, and these dots as well as the 

 entire surface rather shining. 



On the 31st August the larvae were again laying up, 

 and on the 1st of September they moulted the second 

 time. The head was now greenish-yellow, much spotted 

 with black and with much black at and above the 

 mouth ; the body much as before, darkish grey, with 

 yellow subdorsal and spiracular stripes, much spotted 

 with black, surface shining, the black tubercular spots 

 each with a black bristly hair ; an excessively fine, 

 paler whitish-grey thread formed a dorsal line. They 

 were now feeding ravenously and ate some of the 

 youngest leaves of Reseda luteola as well as of B. 

 odorata. 



On the 3rd of September some of the most forward 

 were already laid up for moulting again, and by the 

 afternoon of the 4th two had moulted the third time. 

 By the 6th some were 8 lines or 17 mm. in length and 

 moderately stout ; the head yellow, spotted with black, 

 with black hairs; the body above dark bluish-grey 

 with subdorsal and spiracular stripes of deep yellow ; 

 the belly green ; the warty black spots each bearing a 

 black hair. 



On the 8th and 9th of September some were again 

 laid up for moulting, and one moulted the fourth time 

 on the 10th and most of the others on the 11th. At 

 this time the most advanced larva was one inch long, 

 the others from 10 to 11 lines. On the 15th some 

 were 1 inch 3 lines in length, rather slender in pro- 

 portion, the divisions of the segments and their sub- 

 divisions being well defined ; the yellow head had its 

 component parts delicately defined with light greyish, 

 it was very round in shape and thickly covered with 

 small black dots of two or three sizes, many being 

 exceedingly minute, each emitting a black hair. The 

 tubercular black spots on the body were also some 

 larger than others, all very glossy, and each bearing a 

 black hair. Low down on the side was another yellow 

 stripe, but it was not very noticeable from its low posi-
