OF EPPING FOREST. 157- 



The A. inflatov galls appear in May, giving rise to the sexual 

 generation in July. 



After fecundation, the females of this generation oviposit in 

 the axillary or terminal buds, laying one egg in each bud ; from 

 ihesethe A. glohidi galls develop in September. The larvae are 

 full grown in October when the gall falls to the ground, and 

 pupate in the following autumn, emerging from the gall in April 

 of the second year. 



OCCURRENCE IN EPPING FOREST. 



Andrims globuU. Common. First appearance noted August 

 28th. 



Andvicus inflatov. Common. I have not found this gall so 

 abundant in Epping Forest as in many other localities. When 

 the gall has grown old and woody, buds are produced upon it^ 

 which eventually form twigs, so that these galls do not prevent 

 the growth of the tree. I have often found catkins growing from 

 buds situated on the galls of this species. 



When young they are light yellow in colour, the apex being 

 a very pronounced red or crimson. 



First appearance noted, May loth.

Gall. 



Found in the bud, usually only only just protruding from 

 among the scales. This, however, is not always the case, as I 

 have often found specimens of this gall with only the basal 

 portion enveloped by the bud scales. The gall penetrates deeply 

 into the bud axis. Colony : Reddish brown when fresh. The 

 extreme apex, which is pointed, is lighter in colour, sur- 

 rounded by a dark brownish ring. 



Imago. 



Colour: Black, shining. Antennae'. Dark. Basal joints, reddish. Thorax-. 

 Smooth and shining, pronotum and base of mesonotum, reddish. Scutellum, 

 reddish brown. Abdomen : Dark, ventral surface may be reddish. Legs : 

 Reddish yellow, coxae and sometimes bas3s of femora, dark. IVings : Hyaline.
