The first ecdysis occurred ou June 26tli, four days after hatching. 

 Just previously to this the insect had deepened in colour, the head 

 becoming ochreous, and the body green. The length of the larva in 

 its second instar was 2 mm. Traces of the connexivum now appear. 

 The head is still ochreous and the body green. Down the whole 

 length of the lai-va on each side runs a dark streak, which is reddish- 

 brovoi as far as the hinder part of the thorax, and yellowish the rest 

 of the way. The dorsal yellow spot on the second abdominal segment 

 is still distinct. The abdomen is now broader than the thorax, and 

 the terminal joint of the antennaa is not so stout as before. The sul- 

 cation of the head is not so distinct. A white line runs down the 

 middle of the dorsal surface ; this, however, does not appear to be 

 due to any pigmentation of the skin, but to represent some underlying 

 structure, possibly the dorsal vessel. The excrement in this, as in the 

 other instars, consists of a single drop of thick yellow fluid. 



The second ecdysis occurred on July 1st, and the insect then 

 measured 3| mm. In the third instar a distinct pale and foliaceous 

 margin appears down each side of the body. On the abdomen this is 

 the rudimentary condition of the connexivum, but it appears on the 

 thorax as well, though it is widest in the abdomen. Within this is a 

 dark streak down each side. No trace of the rudimentary wings 

 appears as yet. The legs are pale, but still with a rather smoky skin. 

 In this instar the antennas assume their final proportions, with the 

 terminal joint thinnest, and the basal thickest. The colours of the 

 body are now more opaque than hitherto. 



The thii-d ecdysis occurred on July 7th, and the insect then 

 measured 4| mm. In this fourth instar the rudiments of the wings 

 distinctly appear. 



The fourth ecdysis occurred on July 14tli, when the nymph 

 measured 7 mm. The rudimentary wings are now much elongated, 

 covering three abdominal segments. A thin red stripe now takes the 

 place of the broader, darker stripe hitherto existing down each side of 

 the body. The yellow spot at the base of the abdomen is very dis- 

 tinct, and the connexivum is plainly marked. A dark stain also 

 appears in the abdomen during the later part of this instar. 



The fifth and last ecdysis occvu-red on July 23rd, when the imago, 

 a (J, appeared, measuring 7j, mm. This is a trifle under the normal 

 size for the species, and the reduction no doubt resulted from the 

 confinement and somewhat artificial conditions in which the insect 

 had grown up. At first the body of this imago was green, and the 

 hemelytra were pale ochreous. Subsequently the green colouring
