FOREST ENTOMOLOGY. 



Hedya ocellana, Fib. 



This species is very common in many parts of the south of Eng- 

 land, and the larva is injurious to numbers of trees. Mr E. T. 

 Connold sent me the specimen from which fig. 222 is taken, as show- 

 ing typical injury to the variety of white-leaved poplar known as 

 Populus argentea. It will be noticed that when 

 the larva injures the leading shoot, as seen in 

 the illustration, considerable damage is done to 

 young woods. 



Batodes angustioraxa, Haw. 



It often happens that many of the extreme 

 twigs on the common yew are dead through- 

 out the early part of summer, and having the 

 appearance of being damaged by frost. This, 

 however, is the result of the larva of this species. 

 The larvae hibernate during the winter in cocoons 

 of hair and leaves of the yew-tree. They eat 

 the woody portion of the twig, and thus cause it to wither (fig. 223). 

 In early summer they may be beaten from the yews. 



The larva is about half an inch in length, of a green or yellowish- 

 green colour, with black markings on the sides, and having a dorsal 

 line of a lightish-yellow colour. 

 ■ The pupa is about 3 lines long, and of a pale-brown colour. 

 The moth has fore wings brown with reddish-brown markings, the 

 basal blotch reaching disc of wing ; central fascia broadest on inner 

 margin, gradually narrowing to costa, and oblique by crossing the 

 wing. On its outer margin on the costa is a pale-yellow spot. Then 

 follows the ocellated blotch which extends to the anal angle ; in the 

 middle of it are some darker scales. Hind wings uniform dark-grey. 

 Description from a ? specimen. Expanse 12 to 16 mm.

P.EDISCA OCCULTANA, DoUsL 



I have only found this insect once, and that was an attack on 

 Pinus cembra in !N"orthumberland, on plants which had been pur- 

 chased preceding the attack from a public nursery in the Midlands.
