148 THE ENTOMOLOGIST. 



is a dark green subcutaneous irregular line ; the anal points are 

 rose-pink and white. The head is green, mouth-parts and eye- 

 spots brownish ; legs and claspers also green. 



The first one spun up for pupation on May 10th, and pupated 

 6 a.m., May 13th, 1912. 



Another larva suspended for pupation on May 28th, and 

 pupated early a.m., May 30th, 1911. This specimen was found 

 by Mr. F. Littlewood at night. May 18th, by searching near 

 Kendal, who very kindly sent it direct to me. 



The pupa greatly resembles C. pamjMlus, but has the abdo- 

 men less curved and is rather larger. It measures ^q in. long, 

 and is elegantly proportioned. Lateral view : head angular, 

 thorax slightly "keeled and swollen dorsally, abdomen tapering 

 and rather swollen towards the base and curving to the anal 

 segment, which terminates in a knobbed cremaster amply pro- 

 vided with a dense cluster of amber- coloured hooks, similar in 

 construction to C. pampJiiliis. Ventral surface : the wings 

 swollen near apex, the outline then slightly concaved to head. 

 Dorsal view: head broad and truncated, angular at base of 

 wings ; abdomen swollen at middle, then tapering to anal ex- 

 tremity. The colour at first is a vivid translucent green oyer 

 the head, thorax, and wings ; abdomen yellower green, which 

 gradually becomes greener. After a day old to the end of the 

 fourth day it is of a most intense, brilliant, clear emerald green, 

 finely freckled with greenish-white very faint at first, which 

 becomes more distinct after the fourth day. A dull olive-green 

 streak runs along the inner margin of the wing, which forms a 

 slight ridge bordered along the inner edge with a whitish streak ; 

 these streaks are continued in front of the head but broken 

 through by the antennae and eye ; two other streaks run parallel 

 with the nervures, one medium, the other near the apex. The 

 tip of tongue is dark green, gradually fading away about the 

 middle, a dusky green medio-thoracic longitudinal streak and a 

 dull purplish lateral streak on anal segment. The third, fourth, 

 and fifth abdominal segments have each a subdorsal yellowish- 

 white wart. 



After the fourth day the green assumes a duller and rather 

 deeper hue, and the white freckles show up in stronger contrast. 

 Some specimens are very boldly marked with black. The colour 

 then remains unchanged for a fortnight, after which time the 

 wings assume a more ochreous tinge and become dull orange on 

 the twenty-first day. The colouring of the imago then rapidly 

 develops, changing to purplish-brown on the twenty-second day, 

 while the head ^nd abdomen remain dull green ; and the imago 

 emerged on the following day, the pupal state occupying twenty- 

 three days. 



Another, which pupated May 25th, 1912, emerged early a.m., 

 June 17th, 1912 ; this also being twenty-three days in the pupa.
