PINE CATERPILLARS. 777 
lines, the inner bent inwards at a right angle upon the costa, and sending an angle 
into the extra-discal space ; the line is bent outwards on the first median vein, then 
curving inwards and ending on the hind margin of the wing. The outer line curves 
outwards on the costa towards the apex, is bent on the first median vein, and behind 
is nearly parallel with the inner line. A fine black scalloped hair-line at the base of 
the fringe, which is darker on the points of the scallops. Hind wings with a double 
black curved band beyond the middle, the space within the lines filled in with black 
towards the hinder edge of the wing. An indistinct broad diffuse shade passes across 
the wing just within the middle. On the under side of both pairs of wings the 
discal dots are present, and there is a diffuse dark line common to both wings. Ex- 
panse of wings, 36 mm . 
101. Noctuid caterpillar. 
(Plate vi ; fig. 2.) 
Among the leaves of the white pine at Providence was, October 2 to 
14, a mimetic caterpillar of the following description : 
It began to pupate October 4. One pupa found on the 4th. One of 
the larvae turned black, retaining the three dorsal white stripes, but with 
a row of about ten black spots on each side above, and head large, with 
two black lines, the head generally marbled with dark. This is, I think, 
a state of the present species without doubt. Another one is green, 
with two subdorsal and a lateral row of black spots next both white 
stripes. 
Larva. — Of the usual noctuid form, the body tapering gradually towards both 
ends. Color of the head and body a little paler green than the pine needles. Head 
small, narrower than the prothorax, rounded ; pale honey-yellow, greenish above. 
Body smooth, with four distinct longitudinal white stripes. A median dorsal white 
line and two subdorsal at nearly the same distance from the median as from the 
spiracular one, which is a little broader and more scalloped. Spiracles ringed 
with black, all the feet green; the body of the same color beneath as above. 
Length, 23 mm . 
102. Noctuid larva. 
A white and red striped noctuid occurred on Pinus strobus at Brurs- 
wick, August 5, and one on the hemlock August 14. 
Larva. — Body thick, cylindrical, rapidly tapering towards and bending down 
towards the short stout anal prologs. Head round, green. Clypeus and antennae 
whitish ; labrum reddish, head retractile in the prothorax. Body pea-green, color of 
pine leaves. Three broad dorsal white conspicuous lines ; a lateral similar spiracular 
white line tinged with straw-yellow, lined with red on the upper edge, the white 
line containing the spiracles. Below, near the base of feet, is a similar white line 
interrupted at the sutures. Thoracic feet reddish. Abdominal legs reddish at tip. 
Length, 34 mm . 
103. The pine therina. 
Therina seminudaria Walker. 
We have reared this moth from a caterpillar found feeding on the 
white pine at Providence, E. I., but failed to prepare a description of 
the larva. It passed the winter in the chrysalis state, the moth emerg- 
ing in May.
