18 CORN. 
In the more northerly localities, the mischief is much less impor- 
tant until, with increase of lowness of temperatures, the insect, even 
if transmitted, ceases to be able to establish itself. 
In the case of the sample of North African Barley which I had the 
opportunity of watching, development of the moth did not take place, 
so far as I observed, until more than two months after receipt of the 
infested grain. On April 16th I noticed that some grains of the sample 
which I had received on February 4th or 8th appeared to be showing 
more perforation, and I netted them over, so as to prevent escape of 
any moths that might develop, and on April 20th I noticed the first 
specimen of the 9. cerealella had appeared, and on moving the Barley 
I found another. I did not take the dates of other subsequent appear- 
ance, but one of the last, so far as I am aware, out of this sample of 
Barley did not appear until after May 19th. 
The infested Barley, from which samples were sent me, ‘ was 
harvested in May or June, 1896, was in store in North Africa until 
the following November, when it was shipped to ,»* where it now 
lies’? (February 8th, 1897). My correspondents further remarked :— 
‘«« Although, as we have said before, it is almost invariable to find 
indications of the presence of the moth in the Barley as brought in 
from the fields in Tripoli or Tunis, yet it does not seem to be 
considered as destructive by the natives to any appreciable extent, 
although Barley is sometimes kept closed in silos in the dark for 
two or three years, so it would appear the insects do not increase 
very rapidly.” 
The points involved in the above observation as to how far develop- 
ment is influenced by temperature, amount of light, and also pressure 
from weight of grain preventing ingress of the moth for egg-laying, 
and egress of such moths as may develop in the stored corn, are of 
much practical importance, and I give some notes below, as though it 
may be reasonably conjectured from experience in other countries that 
we are not likely to be troubled with Angoumois Moth on standing 
corn in this island, yet as a stores’ pest it may require attention. 
PREVENTION AND Remepies.—The point where this infestation is to 
be dealt with is in the stored grain. It is laid down by Dr. L. O. 
Howard, Entomologist of the United States Department of Agriculture, 
in the American observations, which are the fullest that we have on 
this insect, that it passes the winter only in the barns and storehouses. 
It will breed uninterruptedly generation after generation in stored 
Wheat. At the time of harvest the moth flies out from the granaries 
to the Wheat fields, and will lay its eggs on grains of Wheat in the
