Amongst the corn attacks few appear to have been at all 
generally prevalent. Hessian Fly has been very little reported, and, 
where observed, noted as doing little 
damage. Gout Fly was much less re- 
ported than is usual, and Corn Sawfly 
scarcely at all. Corn Aphides were 
rather more than customarily present. 
The destructive infestation of the 
Wheat Bulb Maggot (the larva of 
Hylemyia coarctata) was, however, agaiii 
seriously mischievous, mainly in the east- 
em counties. This attack (in which the 
damage is caused by the maggot feeding 
in the " bulb " of the young wheat plant) 
has for some years past caused serious 
loss, and until the past season we have 
not been able to ascertain in what form 
it began on the plant. Now, however, 
by collating last season's information with 
that previously sent, there appears proof 
that the attack cannot be caused by the 
wheat bulb Jlies laying eggs on the young 
wheat, and consequently setting on foot maggot attack, but arises by 
maggot attack from eggs laid in the land during the summer.

We cannot find, after three years' watch (by an expert) on wild 
grasses, in an infested district, that there has ever been any presence 
of a summer brood on grass, nor have we knowledge of its being on
