256 INSECTS JNJURIOUS TO FOREST AND SHADE TREES 
INSECTS INJURIOUS TO THE CEDAR OR ARBOR VITA—( Thuja occi- 
dentalis). 
1. THE CEDAR TINEID. 
Bucculatrix thuiella Packard. 
Order LirprporTEeRa; family TINEID”. 
Feeding on the leaves and spinning slender, small, conspicuous white cocoons attached 
to the leaves, and transforming to a narrow-winged beautiful pearly-white moth, 
dotted and marked with brown. 
The following account is taken from my first report to the Massa- 
chusetts board of agriculture : 
This is a little moth, of which the caterpillar is unknown, though I 
found the moths and cocoons in abundance on a cedar tree in Bruns- 
wick, Me., July 10. It is undoubtedly similar in 
its habits to a little moth which lives not uncom- 
monly on the apple tree, and has been described 
by Dr. Clemens under the name of DBucculatrix 
“—" pomifoliella. Its long, slender, white cocoons may 
be found, at any time after the leaves have fallen, 
« on the branches of apple trees. 
Dr. Clemens says that ‘the larva feeds exter- 
nally on the leaf of the apple, at least at the time 
it was taken, in the latter part of September. It 
is cylindrical and submoniliform; tapers ante- 
_ viorly and posteriorly; with punctiform points 
Fic. 100.—The cedar Tineid, a 3 5 : 
enlarged; a, cocoon, nat. 2nd isolated hairs; first segment with rather 
5 eee abundant dorsal hairs; three pairs of thoracie 
feet and five abdominal pairs. Head small, ellipsoidal, brown; body 
dark yellowish green, tinged with reddish anteriorly; hairs blackish 
and short. Early in October the larva enters the pupa state, wear- 
ing an elongated, dirty white, ribbed cocoon, and appears as an imago 
during the latter part of the following April, or early in May.” The 
present species seems to be undescribed, and may be called Bueculatrix 
thuiella. It belongs to the extensive Tineid family, and its general ap- 
pearance is sufficiently indicated by the drawing. 
Moth.—The body and wings are pearly white, and the antennie are white, with 
brown wings, while there is a low broad tuft of white scales between the antenne, the 
erest being much flatter than in thespecies living ontheapple. Thefore wingsare white, 
and crossed in the middle by a broad brown band, and beyond this band by alterna- 
ting white and brown stripes, crossing from the front edge (costa) of the wing. On 
the end of the wing, and in the middle of the outer edge, is a conspicuous black 
spot, like the eye in a peacock’s feather. To describe the wing and its markings more 
fully—the basal. half of the wing is white, unspotted, except a short, transverse 
brown band, extending from the inner edge, not quite to the middle of the wing. On 
each side of this band is a row of two or three minute dots. The middle band is
