Chapter VIII. 
INSECTS INJURIOUS TO THE BEECH. 
Fagns ferruginea. 
The beech tree in this country seems to be remarkably favored ; a 
fewer number of insects living at its expense than can be said of any 
other kind of tree so useful as this is for timber, for fire-wood, for 
furniture, or as a shade tree. In Europe Kaltenbach records one hun- 
dred and fifty-four species of beech iusects, of which sixty-seven are 
Ooleoptera (six of these, however, are not vegetable feeders, being 
species of Tenebrio, Mordella, etc., and should not have been mentioned 
as peculiar to the tree) ; of Lepidoptera eighty-one species are enumer- 
ated; of Hymenoptera but a single saw-fly occurs on the tree, while 
there are two European species of Cecidomyia and two Aphidae. 
AFFECTING THE TRUNK. 
1. Goes pulverulentus Haldeman. 
"The insect," Dr. Horn says, "is very destructive to living beech 
trees. It bores into those branches which are about 3 inches in 
diameter. The length of the channel is about 8 inches." Mr. Har- 
rington thinks that it probably also bores in hickory, as he has taken 
several specimens on the bitter hickory in July and August. 
The beetle. — The chief point of distinction between this species and tigrinus appears 
to be in the vestiture of the elytra and the length of the antennae. Their size and 
general color are about the same, but the elytra of pulverulentus are uniformly clad 
with short hairs, aud have no appearance of dark bauds. The antennae (at least in 
some specimeus) are slightly longer than the body. (Harriugton.) 
2. Tremex columba Linn. 
Mr. Harrington records finding December 8 a living pupa of this 
insect in the heart of a green beech log over ten inches in diameter. 
AFFECTING THE LEAVES. 
3. Smerinthus. 
A species evidently of Smerinthus and thought by Mr. Saunders to 
be S. exccecatus has been found by Mr. E. B. Reed in September on the 
beech in Canada. He observed that it produced a singing noise when 
handled or disturbed. (Can. Eut., i, p. 40.)
