During the past summer I have found this caterpillar most frequently 
on the common Bush Juniper in Maine, but in former years have beaten 
the chrysalids out of the trees already mentioned. 
The caterpillar is found in July, but becomes fully grown from the 
1st to the 15th of August. Before transforming, it spins the leaves 
together with a few coarse silk threads and remains in the tree. Those 
reared on the Juniper became chrysalids by the 19th or 20th of August, 
and the moths appeared by the 9th of September, so that the pupa state 
lasts about three weeks. The moths continue to appear until the mid- 
dle or last of September. Those found on the Spruce appeared Septem- 
ber 15, and a pupa found on the White Pine disclosed the moth Sep- 
tember 13. Probably by the middle of September all the moths have 
appeared. Whether they hibernate and lay their eggs in spring, or 
whether their eggs are laid in the autumn on the terminal twigs, and the 
species is alone represented by the eggs, remains to be ascertained. 
The moth is easily recognized by the sharp fore wings with the narrow, 
dark, mesial band, which is black and very narrow on the inner edge, 
and by the pale zigzag line reappearing beneath, also by the black 
streak near the apex and a smaller apical black dot. It is closely re- 
lated to the European T. juniper ata, which feeds on the common Juniper. 
DESCRIPTIVE. 
Larva . — Body smooth, cylindrical; head smooth, slightly bilobed, not quite so wide 
as the body. Head and body green, the color of the upper side of the juniper leaves 
on which it feeds. A broad pale glaucous white dorsal band, on each side of which is 
a yellowish-white line, which extends along the sides of the supra-anal plate, but rot 
meeting its fellow at the apex. Anal legs broad and large, green, with two tuber- 
cles which are large and rounded conical. Thoracic legs pink. Length, 16 mm . 
Pupa . — Of the usual family shape ; green, with a white lateral stripe from the head 
to the tip of the abdomen, and another lower down along the abdomen, as well as two 
parallel dorsal whitish stripes. Abdominal spine larger and longer than usual, flat- 
tened vertically, acute, surface corrugated ; two stout terminal bristles excurved at 
the ends, a much smaller pair at base of these and along the sides of the spines two 
additional pairs. Length, (5 mm . 
Moth . — Pale ash, base of fore wings with two bent parallel black lines, the outer 
heavier, and marked with longitudinal stripe on the veiulets. Beyond is a broad pale 
band slightly bent on the median vein. Still beyond is a median band margined with 
black, narrowing more than usual on the inner margin of the wing, where the two 
black margins meet, forming two contiguous black patches; in front the band in- 
closes obscure ashen ringlets. A black discal dot ; beyond, an obscure pale patch. 
A white zigzag marginal line, the sharp scallops inclosing dark dots. Hind wings 
uniformly pale ash color, crossed by two dusky lines. Expanse of wings, *25 nml (one 
inch). 
THE PINE PHEOCYMA.* 
(Plieocyma lunifera Hiibn.) 
DESCRIPTIVE. 
Larva . — Body long and slender, tapering considerably behind the fourth pair of 
abdominal legs. Head not so wide as the body, rather deeply bilobed, with a lateral 
V-shaped white spot. A pair of small prominent tubercles on top of the eighth ab-

nual Report for 1885.
