lines ; head and plate warmer shining green, both 

 dotted with black ; the minute tubercular dots black. 



Third moult, May 14th ; larvae darker dingy bluish- 

 green ; head and plate lighter green, glossy, and dotted 

 with black ; the dorsal and subdorsal lines and spira- 

 cular stripe rather whitish; above this last runs a

 cular dots whitish with black centres. 



Fourth moult, May 17th, 18th, 19th and 20th; 

 larvae at first half to five-eighths of an inch long, but

 thickly covered with minute black freckles ; the black 

 dots on the head very small, and almost obliterated on

 the 28th, 29th and 30th; larvae now immediately 

 after moulting one and one-eighth inches in length ; 

 back and sides blackish olive-green, thickly freckled 

 with blackish, and sprinkled with some pale yellowish ; 

 the belly pale greenish-yellow, the spiracular stripe 

 still yellower, and very much paler, almost white
