52 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
Several species of oak are injured by this leaf miner, which ranges 
from New York to Washington. Sometimes each leaf will contain on 
an average four or five miners, and young shade trees are thus weakened 
by their attacks in June. There are in Washington five or six broods of 
moths. The best remedy is to collect and burn the fallen leaves in the 
spring, since they contain the worms in their final stage before trans- 
forming. 
The moth has white front wings, with three broad irregular bronze bands across 
each one, each band being bordered with black on its inner side. The hind wings are 
silvery. The wings expand 0.28 inch. (Comstock. ) 
56. Brachys wrosa Melsheimer. 
Order COLEOPTERA ; family BUPRESTID#&. 
T have found this small Buprestid upon the leaves of the oak early in 
summer in Maine, and late in May near Providence, R. I. It most pro- 
bably mines the leaves of the oak, but its habits are not yet known. 
(We introduce a cut of B. eruginosa, much enlarged, to illustrate a 
larva of this genus.) 
57. FITCH’S OAK-LEAF MINER. 
Lithocolletis fitchella Clemens. 
Order LEPIDOPTERA ; family TINEID2®. 
Forming a tent-like mine on the under surface of the leaves of different species of 
oaks, a minute, nearly cylindrical, white larva. (Comstock.) 
The mine is visible on both sides of the leaf, while that 
of LD. hamadryadella is to be seen only on the upper side. 
The insect hybernates in the pupa state within the leaves, 
so that the same general remedy of gathering and burning 
the leaves will apply to this as to the preceding leaf-miner. 
The moth has pale reddish saffron fore wings, with a slight brassy hue. 
Along the front edge (costa) are five silvery-white costal streaks ; on the 
inner margin are two conspicuous silvery dorsal streaks, while the hind 
wings are grayish fuscous. (Comstock. ) 
58. THE OAK-LEAF PHYLLOXERA. 
PAS larva Phylloxera vileyi Lichtenstein. 
of Brachys 
weruginosa.— 7 : : ea 
From Pack. Forming a yellow circular spot on the under side of the leaf, but show- 
ard. ing plainly above, of the white and post oak; the species of small size 
and unusually slender, and with long tubercles in the pupa. (Riley.) 
INJURING THE SEED (ACORNS). 
59, THE ACORN WORM. 
Balaninus rectus Say. 
Order COLEOPTERA ; family CURCULIONIDE. 
A erub like the chestnut borer, boring into the acorns and transforming into a simi- . 
lar beetle, which is ‘‘easily distinguished from FP. nas’eus by the finer, more rectilinear
