264 THE ENTOMOLOGIST. 



the spiracles are outlined with dark brown ; legs and claspers 

 ochreous. There is no dorsal collar on the first segment as in 

 the previous stage. 



Second moult, May 19th, the second stage occupying thirteen 

 days. 



After second moult it measures 7 mm. long ; ground colour 

 bright green ; a medio-dorsal darker green stripe bordered by a 

 pale yellowish line ; a fine subdorsal whitish line bordered on 

 each side by a darker green line, and a whitish lateral line. The 

 head is light greenish-ochreous, clypeus and medio-frontal line 

 darker and continuous with the body stripe, eye-spots black ; the 

 surface is finely granular and sprinkled with minute black points. 

 The body is likewise granular, and is beset with minute stud-like 

 processes ; the anal segment is fringed with whitish hairs. The 

 ventral surface is flattened. If disturbed when out of its dwelling 

 it falls to the ground and rolls in a complete ring, remaining so 

 for a short time. 



Third moult, May 27th. 



After third moult measuring 14 mm. long. Head very pale 

 whitish-ochreous-green, with a slightly darker central band con- 

 tinuous with the medio-dorsal stripe, clypeus very indistinct, 

 otherwise it is similar to previous stage ; the pale spiracles are 

 placed on a very fine pale line. 



Fourth moult, June 6th. 



After the fourth and last moult, fully grown, the larva 

 measures 21 mm. long. The head is globular, the surface reti- 

 culated and sprinkled with minute white bristles, eyes dark ; the 

 colour is ochreous-green with a slightly darker green band down 

 the centre, but very faint. The body is swollen in the middle, 

 tapering at the ends, the first segment is small and narrow, the 

 anal segment terminating in a projecting flap, the segments 

 subdivided into six divisions, the first one being much the widest ; 

 the ground-colour is grass-green with a rather darker green 

 longitudinal medio-dorsal band intersected by a central paler 

 line, and bordered on either side by a pale yellowish line, and a 

 similar subdorsal line ; the small yellow spiracles are situated 

 on a fine pale line followed by a conspicuous yellowish-white 

 lateral stripe, the ventral surface is darker green, on each clasper 

 is a whitish crescentic mark. The first and last segments are 

 wholly green. The legs fleshy-ochreous. Between the ninth to 

 tenth and tenth to eleventh segments is a ventral patch of white 

 waxy substance. 



The larva became fully grown and spun up for pupation on 

 June 15th, and pupated June 17th. The larval state occupying 

 311 days. 



The pupa varies in length from 16 mm. to 19 mm. long. It 

 is slender and tapering.
