observations of Fniiey (G) tincl myself, are usually brighter than the- 

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



the latter descriljes their 

 colour as being very 

 much more varied than 

 we usually find in Eng- 

 land. The male, lie says, 

 " in wedding attire is 

 either of a lively green 

 striped on the back with 

 j'ellow, a dark yello^\• 

 with broad stripes, or 

 almost completely green 

 ^vith dark yellow dots, 

 the abdomen entirely 

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

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

 green or greenish-yellow on other occasions." The amount of ^■aria- 

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

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

 These adttlts 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. Tairing takes place towards September, and from then on 

 into November they deposit 

 their eggs. Before coptilating 

 Schmidberger (1) says five or 

 six of them assemljle 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, ^^'hich remains there 

 imtil pairing is over. The 

 eggs are laid in ^•arious places, 

 but especially on the spurs, 

 generally around the leaf- 

 ridges, some placed horizon- 

 tally, others in a more irregular manner ; many others are placed on 

 till' fine hairs on the year's growth and some on the buds. 1 have
