160 ANTHOCHARIS OARDAM1NES. 



belly they are not so numerous ; the spiracles are 

 inconspicuous being whitish, but not so white as the 

 stripe on which they are placed. 



The larva fastens itself for pupation by the anal legs, 

 and with a belt of silk, and soon assumes an arched 

 posture, and becomes a pupa in less than two days ; 

 the beaked head-piece when first disclosed hangs 

 down limp, like the tassel of a man's old fashioned 

 night-cap, and the wing-cases project at first but little ; 

 in a short time, however, the form fully develops, and 

 the pupa skin hardens. The pupa is 20 mm. long, very 

 slender, and very attenuated at either end ; the general 

 outline of the back from end to end is concavely arched, 

 and it is much flattened, though the thorax swells out 

 just a little ; the head ends in a long beak or horn ; 

 the tail has no spike, but the tip is set with rounded 

 knobs and small bristles (under the microscope 

 reminding one of the appearance of a raspberry) ; on 

 the ventral side the wing-cases swell out to a somewhat 

 acute point just at the middle of the body; along the 

 spiracular region is a ridge dividing the dorsal and 

 ventral surfaces ; the colour at first is a dull deep 

 green. One of my pupae in about ten days became pale 

 grey tinged with pink, darker on the back with a pale 

 dove-grey middle line and a broad stripe of dove-grey 

 on each side, the edge of the lateral ridge pinkish- 

 white, the nervures of the wings paler than the ground ; 

 the other pupa has retained its green colour to the 

 date of my present writing, and has the anal tip pink.

In 1861 I received eggs of this species from Dr. 

 Knaggs, July 27th, and the larvse were hatched August 

 18th, but I have no further notes of their progress. 

 In 1863 I again had eggs, and on March 31st, 1864,
