observations of Furley (G) and myself, are usually brighter than the 



females, but according to Schmidberger (1) it is the reverse ; moreover, 



the latter describes their 

 colour as being very 

 much more varied than 

 we usually find in Eng- 

 land. The male, he says r 

 " in wedding attire is 

 either of a lively green 

 striped on the back with 

 yellow, a dark yellow 

 with broad stripes, or 

 almost completely green 

 with dark yellow dots,

yellow. The females are of a prettier colour and somewhat larger; 



the entire back of the female, reaching as far down as the forceps 



at the extremity of the abdomen, is red, striped with greenish-yellow 



and brown and the abdomen is orange-yellow or green ; they are 



green or greenish-yellow on other occasions." The amount of varia- 



tion differs in different places and in different seasons. It is the 



general greenish shade that will be chiefly noticed by the growers. 



These adults live on the foliage all the time, sometimes we find them 



at rest on the boughs and trunks. They apparently do no damage in 



this stage. Pairing takes place towards September, and from then on 



into November they deposit 



their eggs. Before copulating 



Schmidberger (1) says five or 



six of them assemble on an 



apple leaf and each male 



selects his female, and that 



whilst pairing is going on a 



tubercle appears on the last 



ring of the extreme part of 



the body, \vhich remains there 



until pairing is over. The 



eggs are laid in various places, 



but especially on the spurs,

the fine hairs on the year's growth and some on the buds. I have
