OAK. 
Leaf Roller Moth. Tortrix viriclana, Stephens. 
Moth ; caterpillars hanging from their threads ; and rolled leaf. 
The Oak Leaf Roller Caterpillars are noticed by Mr. Robert Coupar 
as having caused much damage to the Oak foliage at Colenden, Perth¬ 
shire, the attack being most severe to trees that either stood alone or 
on the outside of plantations, or by the side of drives. * 
ONIONS. 
<* 
Onion Ply. Anthomyia ceparum, Curtis; A. antiqua, Meig. 
Leek or Shallot Fly. Anthomyia platura, Meigen. 
The injury to Onion crops in this country has commonly been 
supposed to be caused by only one kind of fly; but in the course of 
1882, specimens of Maggots infesting Onions in different parts of the 
country having been submitted to Mr. R. H. Meade, of Bradford, he 
reared from these another species of Onion Fly, the Anthomyia platura 
of Meigen, sometimes known on the Continent as the Shallot Fly, 
besides the well-known A. ceparum, or, as it appears now more generally 
called scientifically, the A. antiqua. 
These small two-winged blackish and grey flies are much alike 
in appearance, but for practical purposes it may turn out of great 
service to know there are two sorts, as they do not seem to be quite 
alike in their habits. 
* Leaf Rollers were also injurious to the (Sycamores, or Planes, as they are 
sometimes called in North Britain.
