PSYCHE. 



[August — December 1880. 



dotted with yellow, the dots becomhig 

 more numerous after the fifth segment. 



Thei'e were nine obliques of clear 

 yellow, their •• trend" being the reverse 

 of those of Sphinx larvae. 



The feet and props were pale green 

 with reddish tips, except the anal props, 

 which were long, thin, and like the 

 body in color. 



All the props ended in curved and 

 speading tips. The last moult was like 

 the one before it, and occurred one 

 week before the larvae spun leaves to- 

 gether for pupation. The pupa formed 

 in five days from the spinning and was 

 of a light brown color with no noticeable 

 peculiarity. The moth emerged in 

 June, 1 889, and was kindly identified 

 by Mr. John B. Smith. 



Callosamia angulifera Walk. 



These eggs were sent us by Miss 

 Emily L. Morton, with no date of lay- 

 ing, but the egg-period is probably 

 about that of C. promethea. 



The eggs closely resembled those of 

 C. promethea., but were whiter. 



Many of the eggs turned lead color by 

 July 20, but a few became green, and a 

 few yellow. All hatched on 20 July. 



The young larvae were 4 mm. long, 

 and bright yellow with a dark head. 

 The head had two light bands across it. 

 There was a black transverse band on 

 the top of the second segment. The 

 anal segment had two dark transverse 

 lines, and a dark line showed faintly be- 

 tween the segments. 



The feet were grayish yellow with 

 dark tips. Props yellow. Each seg- 



ment had six warts and spines, except 

 the first and last which had four. 



27 July. First moult. Head yellow 

 with a dark line tind dark patch across 

 it. 



Each segment had two transverse 

 black lines on dorsum. Body-color 

 greenish yellow. On the first segment 

 were four black warts with black 

 spines. On the eleventh segment were 

 three warts, the middle and largest one 

 being on the dorsal line, and two warts 

 just behind these. On each of the other 

 segments were six yellow warts with 

 yellow, black-tipped spines. Anal 

 shield with a transverse line and patch 

 of black. Feet and props pale yellovv. 



31 July. Second moult. Head 

 pale green with dark mouth-parts. 



Body whitish green, with two indis- 

 tinct black lines on each segment, and a 

 transverse row of yellow warts, each 

 having a spreading crown of yellow 

 spines. Just behind the head the row 

 of warts was followed by a heavy black 

 line. 



Feet and props whitish green. Anal 

 shield with a black line and patch. 



6 Aug. Third moult. Head green, 

 with black dots over the top and a black 

 line across the face just above the 

 mouth-parts. 



Body very white-green, smooth, 

 tapering from third segment to the 

 anus. 



From the third segment to the anal 

 shield, there was a thick wavy ridge 

 just below the spiracles. This ridge is 

 one of the differences between these 

 larvae and those of protnetkea. It
