dissected out of one female was fourteen, but it is probable that the 

 actual number is more than this. 



The eggs live in the shoots all through the winter and the young 

 larvae hatch from them the following April or May. 



Description of the Instars. 



Instarl (PL IX, fig. 5). Length 1- 1-1-4 mm., small, slender, fragile, semi- 

 transparent. When just hatched pale yellow, turning greenish and darker 

 in a few hours. On the head and thorax are smoky patches interrupted 

 on the thorax by a mid-dorsal pale line which bifurcates on the head at 

 the level of the eyes. The smoky colour is in the chitin whilst the actual 

 colour of the bug is due to pigments in the tissues of the body. 



Head relatively large, marked longitudinal groove just in front 

 of vertex; yellow, with smoky shades interrupted by a Y-shaped 

 pale line. A row of short thick black hairs is present on the vertex 

 and a few longer hairs on the front of the head. Eyes, compound, 

 large, deep carmine in colour, nearly touching the pronotum. 



Thorax increases in width up to the metathorax. 



Pronotum almost rectangular, anterior margin slightly curved, 

 angles rounded. Light green with smoky patches interrupted by 

 mid-dorsal pale line. Row of hairs on posterior margin and a few 

 irregularly scattered hairs. 



Mesothorax with smoky patches ; broader than prothorax. 



Metathorax shortest and broadest, smoky patches narrower. 



Abdomen pyriform, slightly longer than broad; greatest breadth 

 across segments II-IV. (In a well-fed individual the abdomen is dis- 

 tended and almost circular in cross- section; but in a starved specimen 

 it becomes flatter and the first two abdominal segments become 

 telescoped. ) Yellowish green, with a pale hne extending from segments 

 III-X, smoky patch on segment I. A large circular yellow area is 

 present in the mid-dorsal region of segment III. This is the pocket- 

 shaped dorsal abdominal gland seen through the cuticle; its orifice 

 is between segments III and IV ; the anterior lip is the black thickened 

 part of the anal margin of tergite III. The anterior part of tergite IV 

 opposite this is dark and the two lips enclose a light coloured area. 

 A row of thick short black hairs on each tergite, longer on segments 

 VIII-X; segment IX also has a number of small hairs. Whole 

 abdomen covered with a fine fur of setae. 



Appendages. 



Antennae medium-sized, slender, at first pale yellowish green,
