INSECTS INJURIOUS TO THE CEDAR OR ARBOR VITH. 257 
broadest on the hind edge. Beyond and arising from the costa, where they are broad- 
est, and extending to the opposite side of the wing, are six brown lines, alternating 
with white interspaces. These lines run together in the middle of the wing, brown 
dots being added, but which end as distinct lines on the inner edge of the wing. The 
three outermost lines are much curved, and, with the curve of the fringe, form a cir- 
cular area, in the middle of which, on the base of the fringe, is the curvilinear, rather 
thick, dark brown spot. The leng fringe on the end of the wing is white at base 
and brown at the end. The hind wings are pale brown, acutely pointed, with a long 
silvery fringe. ‘The tibie and tarsi of the fore legs are brownish, while the hind legs 
are white, with a long fringe on the hindermost tibie. The length of one fore wing 
is .18, and the length of the body is .13 inch. y 
The cocoon is white, tough, dense, slender cylindrical, and .20 inch in 
length. It is fastened by one side to the leaf, and differs from that of 
the apple Bucculatrix in not being ribbed longitudinally. A minute, 
beautifully brilliant green ichneumon (Chalcis) fly seems to attack in 
considerable numbers the chrysalids of this insect, as nearly half of 
those reared by me turned out one of these parasites. It is a species of 
a genus allied to Eulophus, having the antenne pectinated, the terminal 
joints throwing off five long branches. It differs, however, from Eulo- 
phus among other characters by having a short, thick body, a small, 
conical abdomen, and short, thick antenne. The fore wings are broad, 
triangular. : 
We noticed these beautiful moths again in 1881, at Brunswick, flying 
about a cedar hedge in considerable numbers from the middle of July 
until early in August. 
2. THE FIR SAW-FLY. 
Lophyrus abietis Harris. 
False caterpillars closely resembling those found on the fir, and iden- 
tical with that found on the low-bush juniper, occurred on two cedar 
hedges in Brunswick, from July 18 to the last of August. But a few 
scattered individuals occurred. We will give adescription of the variety 
found on the cedar. Body cylindrical, broadest on the thoracic segments ; 
all the segments finely transversely wrinkled. Head small round, deep,. 
amber-colored; eyes black. Body pale green with a broad diffuse dark 
green medio-dorsal and a lateral stripe. Body paler beneath. Thoracic 
feet black. Eight pairs of abdominal feet green. Length 13™™. One 
was found without the three dark stripes. This species differs from the 
others in the caterpillar having no dark spots on the body as seen in most 
Lophyrus larve. 
3. THE PROMETHEA MOTH. 
Callosamia promethea (Drury ). 
Said by Mr. Riley to feed on the arbor vite. (Fourth Rep., 123.)
