CORN. 
These were on the concave side, and usually at the end of the grain 
occupied by the germ, where the outside is softest. On the 9th of 
March of the following year I found numerous Wheat-grains, each 
containing a maggot. These were of various sizes, from about the 
sixteenth to under the eighth of an inch in length, white, thick, and 
fleshy, legless, with chestnut head and 
jaws also chestnut-coloured; darker at 
the extremity; bluntly pointed and waved 
into two blunt teeth (see fig.). A few 
chrysalids were present, but at the above 
date they were all dead, in different stages 
of development. About a month later 
(on the 11 th of April) no more chrysalids 
had formed, and at the beginning of June 
I only found two more beetles, and though 
about one grain in ten had a tenant, for the most part it was only 
still in maggot state and often stunted, and in the few grains which 
contained a developed beetle this was usually small, distorted and 
dead. On the 6th of October following I found numerous beetles, but 
still not by any means corresponding in number with the infested 
grains of corn, and some of these beetles only about half the usual 
size. 
In the early part of the experiment I placed the beetles in reach of 
fire-heat, which threw them into a very active state ; afterwards they 
were in the temperature of a living-room constantly used,* and as 
even with this the result was that in the course of fourteen months I 
only obtained one brood, and this not as numerous as the parent 
weevils, and even of these some were half-sized or variously not in a 
natural condition : from these points it appears that the non-breeding of this 
Spotted Granary Weevil in England to any hurtful extent is much 
confirmed. This kind is usually easily known by the four lighter spots 
on the wing-cases. 
In dealing with Granary Weevil, which are amongst the most 
common of our dry-corn pests, we have an enemy of which we know 
the history, and the habits, and that with due care it may be kept in 
check within our granaries, and be prevented from being brought to 
where it may be spread to them, likewise it cannot do harm to the 
growing crops. 
But great risk, to my thinking, lies in the use of the foul screenings 
which get spread abroad in the country by reason of their cheapness. 
It is quite open to possibility that Hessian Fly thus came to us; 
because, as we now know, the chrysalids are to be found in the fine
