but not thereafter. The beetles winter over and lay their eggs soon 
after the leaves open, adults of the new generation appearing from 
the first part of May to the first part of June, and continuing at 
least thru the latter month. The remainder of the life history is 
unknown. 
DISTRIBUTION OF SPKCIES 
The species was first recognized and described by Dr. G. H. 
Horn in 1878, from specimens of the adult from Michigan and 
Colorado. 
In Illinois we have seen it or its characteristic injuries at about 
thirty different towns : in Pulaski, Union, Jackson and Williamson 
counties in extreme southern Illinois ; in the prairie fruit region of 
Washington, Jefferson, Marion, Clay, Wayne, Edwards and Rich- 
land counties ; in Jersey, Calhoun and Pike counties in the western 
part of the state; and in Coles and Christian counties in south- 
central Illinois. It is represented in our collections by several speci- 
mens labeled "N. 111.", and by one from Normal, McLean county; 
and it will probably be found to infest apple trees thruout the state. 
NATURAL CHECKS AND REMEDIES 
The species is probably usually kept under control by a chalcid 
parasite (a species of EulopJius, according to Mr. A. A. Girault), 
which has been reared by us three times. In mines collected May 
8 and 22 pupae were found May 21 and 25, and adults of this 
species were secured May 26 and 27. From material collected 
May 15 a considerable number of these parasites were bred May 30 
and June 3. 
The injuries caused by the apple flea-weevil do not as yet ap- 
pear to be serious enough to make insecticide applications necessary. 
If they were, an arsenical spray applied near the end of May. would 
no doubt kill the beetles, since they are at that time feeding on the 
leaves. Especial care would be necessary to reach the lower sides 
of the leaves with the spray, since they feed mostly on that side, 
and do not eat thru the leaf. 
The Strawberry Leaf-roller 
{Ancylis com plana Frol.) 
This troublesome enemy of the strawberry grower is an active, 
small, slender, greenish larva (Fig. 22, a, h, d) about half an inch 
long when full-grown, and having seven pairs of legs. It folds 
the strawberry leaf, living within the fold, where it spins a silken 
web and feeds on the leaf tissue. The foliage is often thus seri-
