suppliers, that of eschewing purchase of seed from countries known to 
be much infested. As to the next step backwards up to the fountain¬ 
head of the mischief—how to prevent attack—one point is not to use 
infested seed, and—and this most especially—in Bean seed-growing 
districts, to change the crop frequently, or for the growers, by agreement, 
to sow no Beans or Peas for one season in an infested district. If this 
regulation could be established, as was proposed a few years ago in 
Canada, where the Pea Bruchus is a serious cause of loss to growers, 
it would make an immediate difference in the condition of our im¬ 
ported supplies. 
Various methods of destroying the Bruchus in the seed have been 
suggested, as dipping it in oil, in water just hot enough to kill the 
“ Seed Beetle” but not the seed; likewise putting infested seed in 
water has been advised as a means of dividing the injured and 
uninjured, by floating. But all these plans seem of very doubtful, or 
less than doubtful, utility ; and, without entering on the different kinds 
of Bruchi or “ Seed Beetles ” which infest crops in England, it may 
be safely stated that the great security is for the buyer to see that his 
sample is not infested, and for the importer to avoid infested districts.

Moth, caterpillar, and chrysalis. 
During the last few years specimens have been occasionally sent of 
a'caterpillar which resembled the “Surface-caterpillars” in manner 
of feeding, but was much smaller, and white or of a yellowish tint. 
Early in the spring of the present year a further supply of speci¬ 
mens were sent me, which were then doing damage to winter Beans, 
and which agreed well with the descriptions of the caterpillars of the 
“Small” or “Garden” Swift Moth, Hepialus lupulinus. As the 
attacks of this caterpillar have not been brought forward amongst 
regular crop-pests before—and there appears reason to think that a
