abundant this season. The pest disappears about the first week in 
July. 
The bagworm, 7hyridopteryx ephemereformis, has been a serious 
pest In many places in the State to arbor vite, apple, and locust. In 
two instances it injured apple trees in the nursery rows. Hand pick- 
ing was very effectual. | - 
The black peach aphis, Aphis prunicola, was quite abundant in 
some young peach orchards in May. : 
In three cases a June beetle, Anomala binotata, was reported as eat- 
ing the foliage from pear and apple trees. 
The red-legged fiea beetle, Crepidodera rujipes Linn., was sent tome 
from three localities where it was found injuring the foliage of young 
peach trees. The trees in all cases were planted on newly cleared 
lands. 
The American elm scale, Chionaspis americana Johns., was sent to 
me from Geneva, N. Y., and from Ames, Iowa, upon elm. ; 
An undetermined species of Lecantodiaspis was found by the writer 
in Baltimore County upon wild honeysuckle (Diervilla). 
An undetermined species of aphis and cutworm was found doing 
serious injury to lettuce in a greenhouse in Montgomery County. 
INSECTS OF THE YEAR IN OHIO. 
By F. M. Wesster, Wooster, Ohio. 
In point of destruction the Hessian fly outranks every other insect, 
when considered in connection with the wheat crop of 1900. It is 
doubtful if there will be over 20 per cent of an average crop in Ohio; 
the remaining 80 per cent may be largely charged up to the ravages 
of this pest. As an average crop in Ohio amounts to, approximately, 
40,000,000 bushels, the loss may be computed at 32,000,000 bushels, 
which at the ruling market price would mean a loss of $22,400,000, - 
-at least three-fourths of which, or $16,800,000, can justly be charged 
up to the ravages of the Hessian fly. More extended studies of this 
outbreak and some of the meteorological phenomena connected there- 
with are given in another paper. The unprecedented abundance of the 
pest this year may be attributed largely to the almost total lack of 
parasites, the retardation of the fall brood over the northern half of 
the State, and the extremely favorable weather during the autumn 
of 1899, which enabled all but the very latest deposited eggs to hatch 
and the larve develop to the ‘*flaxseeds” and thereby defy the adverse 
influences of winter. In many localities the later sown wheat escaped 
fall attack, and up to May 1, 1900, was uninjured, but tne flies devel- 
oping in the earlier sown fields seemed to haye migrated en masse and 
settled down on those sown later, and the result is that in many cases 
the destruction is as complete in the one as in the other.
