freckled between ; there are 6 on the costa, the 3 nearest the base 
are the largest, the 3rd semilunate, the 2 following minute, and 
on the inner margin is a brown oblong spot, forming an acute 
angle with the 3rd ; the fringe is long and brown, with pale 
stripes : inferior wings smaller, lanceolate, of a pale mouse colour, 
coppery towards the tips ; the fringe very long and fine : 6 legs ; 
hinder thighs very short ; anterior shanks short, with a hairy 
spine on the inside, the others spurred at the apex ; the posterior 
long, clothed externally with long hairs, having a "2nd pair of long 
spurs near the base ; tarsi longer than the tibize, slender, taper- 
ing, and 5-jointed; claws very minute : expanse of wings 5^ lines 
(fig. 10, greatly magnified). The female is larger and darker. 
I cannot describe the trophi or organs of the mouth with the 
accuracy to be desired, owing to my not being able to obtain 
living specimens of the moth ; but dissections of an allied species, 
very destructive to clothes, have been figured and described in 
the ' British Entomology,' pi. 511. 
It is difficult to guard against the introduction of this moth, 
since it deposits its eggs on the sheaves in the field, as well as 
after the grain is stored and threshed out, and it will feed as freely 
upon barley, rye, and oats as upon wheat ; and Leuwenhoek adds, 
" That these worms are not only destructive to cOrn, but are also 
in old timber, books, boxes, woollen stuffs, and the like." In re- 
flecting upon the economy of this destructive insect, it is not diffi- 
cult to suggest palliatives, if not remedies, and it appears to me 
that if the following rules were strictly attended to, few persons 
would suffer from the inroads of this insect : — 
1st. Before replenishing an empty granary or loft, the floor 
should be well scoured with hot water and soft-soap, or lees if 
practicable, if not it must be well brushed with a fine stiff broom, 
to clean out the chinks or fissures between the boards. The 
roof and beams should be whitewashed, as well as the walls, with 
lime-water, used as hot as possible ; and these operations would 
have greater effect if performed in the winter months. I pre- 
sume coal-tar would be even better, if the scent be not communi- 
cated to the grain. Sprinkling the floor with salt dissolved in 
strong vinegar has been recommended, and might be very ser- 
viceable. 
2ndly. In granaries already stored, where the caterpillars are 
at work, whatever method for their destruction may be resorted 
to, by heat, ventilation, or otherwise, it must be employed during 
the summer, from the end of May to the end of August ; occa- 
sionally a month earlier or later, as during the winter these larvae 
are not to be found amongst the corn-heaps ; they retire in the 
autumn, to conceal themselves in fissures and cracks in the floors 
and walls, and form their cocoons.
