100. The pine pheocyma. 
1'htocyma luniftra Hiibner. 
The caterpillar of this uoctuid moth is of frequent occurrence on pine 
trees, especially the white pine and pitch pine in Maine, where I have 
observed it for several years. In northern New England the larva 
occurs through August into the first week of September, when it trans- 
forms into a chrysalis, the moth appearing May 10. I am indebted to 
Prof. John B. Smith for the identification of the species. 
The caterpillar is, like nearly all those which live on trees, protected 
from the observation of its enemies, such as birds, ichneumons, etc., 
by its similarity in color to the bark of the twigs on which it often 
rests, while the reddish stripes are concolorous with the base of the 
needles of the pine. 
The caterpillars vary a good deal. Some are wood or horn brown, 
or the body is decidedly reddish, with the longitudinal baud more dis- 
tinct than usual ; some are green with white lines, but the warts and 
head as in the more usual varieties. They are closely similar to the 
larva? of Homoptera and Catocala. 
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- 
dominal segment, and in place of them on the segments is a pair of more widely 
divergent short black dashes ; on the segment next to the last is a transverse ridge. 
Anal legs long and slender. General color of the body wood or horn brown, of the 
shade of old twigs, sometimes reddish or greenish. Head marbled with a set of 
transverse wavy whitish lines on each side of the median line. Body with a lateral 
row of black dots ; beneath much paler, glaucous green. Leugth, 35 mm . The larva? 
are very variable ; in some the body is reddish with longitudinal bands much more 
distinct than usual ; in some the body is pale pea-green, a little paler than the pine 
leaves : there is a firm, quite wide medio-dorsal line, and on the sides a wider white 
line next to the broader very conspicuous pale red spiracular line, which is similar 
in color to the reddish sheath of the pine leaf. Head reddish, with the characteristic 
oval white spots on each side. In others (as pitch pine) the body is beautifully mar- 
bled with gray and whitish. A Y-shaped white spot on the side of the head. On 
the segment next to the last abdominal are two small inconspicuous warts. A 
faint, broad, grayish-white dorsal band, broadly interrupted at the sutures of the 
segments by an irregular transverse umber-brown stripe. A faint lateral broad band, 
containing on the side of each segment a clear white point. Length, 42 mm . 
Pupa.— Of the usual rather slender Catocala shape, covered with a slight whitish 
bloom. The abdominal tip rather blunt, the surface corrugated with irregular longi- 
tudinal furrows above and on the sides; spine small, bearing at the end two very 
large, long, stout bristles curved outwards at the ends, which are blunt ; at their 
base are two pairs of slender bristles. Length, 17 mm . 
Moth.— Body and wings dark ash-gray and reddish brown : thorax crested, dark 
reddish brown, with two blackish transverse lines. Patagia with a white stripe be- 
hind *he middle and white scales at the tip ; hinder part of the thorax dusted with 
white. Fore wings black and reddish brown at base, with interrupted and broken 
Mack and white lines. Within the middle of the wing is a broad, slightly sinuous 
whitish-gray band. A large black mark forming a hollow square, the hollow gray- 
ish, at the end of the discal space. Beyoud this spot are two nearly parallel black
