months the pup® are found. Previous to the pupation the larva 
srpins a cocoon of silk within a bunch of leaves, or sometimes 
attached to a twig.

I have not myself seen this species on the strawberry in Illinois; 
and it is reported as a strawberry insect on the authority oi Mr. 
Saunders who says that he has found it “feeding very commonly 
on this plant. If it were to become too abundant to be destroyed 
by hand, it would, of course, be easy to kill it with arsenical poisons, 
administered in midsummer, as even the first brood ol the cater¬ 
pillars, where there are two, does not appear until after the straw* 
berries are picked.

Passing mention may be made in this connection of this de¬ 
structive 0 pest, which last year swept through strawberry fields m 
Southern Illinois, stripping the plants of foliage, and leaving the 
unripe fruit upon the ground gnawed from the stems. 
The fields might be protected from its attack by the barriers used 
bv grain farmers to arrest its march. The most successful of these 
is a deep furrow plowed around the field, the inner wall of which 
may be made slanting from the top of the furrow downwards 
and inwards towards the field, by the use of a spade, lhe 
worms collecting here may be killed by dragging a log along the 
furrow; or holes may be dug in it at intervals, m which the} 
will rapidly collect, where they may be mashed by thousands. 11 
is also probable that the progress of an army of these worms coulc 
be arrested by thoroughly treating a belt of the plants m front o 
them with Paris green. It should be remembered that measures o 
this sort which will not pay for ordinary farm crops may never 
theless be employed with great profit for products as valuable as tn< 
strawberry.

An illustration of the damage to strawberries which these insect, 
are liable to do under favoring conditions, is afforded by the accouE 
given by Mr. Saunders, in the article already cited, of the minne 
due to a species-occurring in Canada, but the name or wincii j 
does not mention. He says: “This is an insect which has 
most unusually injurious during the past season on fruit plantatioE 
on the borders of Lake Huron, near Sarnia. At first its habits w 
not understood, and it pursued the ‘even tenor of its way . unmterrup ^ 
night after night; the perplexed fruit-growers not knowing why it Wc 
that every day the foliage on their fruit trees and strawberry pa c 
grew slimmer. But soon it was found that the enemy waR a mg 
worker, and this knowledge of its habits was at once turne
