in the leaf substance. I have failed to detect any gummy covering 

 deposited by the female said to be present over them. In colour 

 they are almost white to a pale translucent green. The length of 

 the egg stage is from live to twelve days, according to climatic 

 conditions (4). 



The larvse are green when young, with black heads and small 

 black specks on the body. The first and part of the second segment 

 and the last two segments are orange-yellow. Over each leg is a black 

 spot, elevated, forming a 

 kind of tubercle ; over 

 each proleg are a pair of 

 black spots, and on the 

 upper part of the seg- 

 ments are numerous 

 black points ; on the first 

 are eight black spots, on 

 the second and third six 

 on each side ; on each 

 abdominal segment are 

 twelve spots, exclusive 

 of the pair on the legs ; 

 the spots on the dorsum 

 are roughly arranged in 

 two parallel rows of six 

 each, while those below 

 are irregularly placed. 

 On the upper surface of 

 the anal segment is a 

 large black patch, and on 

 each side where the patch 

 narrows are six or seven 

 small black spots. After 

 the last moult the larva? 

 assume a different appearance, they become pale apple-green to 

 bluish-green, orange behind the head and on the tail, whilst the 

 head is pale brown or dull green instead of being black no spots 

 occur at all. Now and then pale yellow forms occur in this stage. 

 When full grown they reach nearly f inch in length. 



When first hatched the larvae feed off the epidermis of the leaf; 

 after a day or so they commence to devour little round holes right 

 through the surface, the larvse holding on to the edge of the hole. 

 When they get about half -grown they disperse over the bushes and
