INSECTS INJURIOUS TO THE PINE. 207 
color and form of the body is surprisingly like a dead red needle of the tree; it 
- could readily be mistaken for it, since the end of the body suddenly tapers like the 
pine-needle itself. Color rust red, a darker dorsal line. 
85. THE SNOUT MOTH CATERPILLAR. 
Order LEPIDOPTERA; family PYRALID®. 
Larva.—Body with ten pairs of proplegs; body pale green, concolorous with the 
leaves on which it feeds; head small, much narrower than the body, of a very pale 
amber color; a faint dorsal and two subdorsal linear pale lines. Lateral ridge pale 
yellow. Each segment above with four black minute papill arranged in a trapezoid, 
and two on the side. All the legs concolorous with the body. Occurred August 17, 
on pitch-pine at Brunswick, Me. 
86. Another span worm, living on the moss on pine trees, and found 
alive in Cambridge, Mass., in January, by Mr. Hill, is closely assimi- 
lated in color to the moss itself. Also we have found a handsome noctuid 
caterpillar (87) on the pitch-pine at Salem, Mass., which is red, marked 
with yellow, and would be readily overlooked from its mimicry of the . 
red twigs of the pine. It may be the larva of a species of Trachea, and 
may represent the Trachea piniperda of Europe. 
88. THE PINE TUBE-BUILDER. 
Order LepipoPrEeRA; family TORTRICID A. 
Cutting off the ends of white pine needles, and spinning together a tube of the 
stumps, in September, and also to be met with probably early in summer, a pale-green 
leaf-roller, pupating late in September. 
About ten years ago I found, in September, on the young white pines 
in the grounds of the Massachusetts Agricultural College, at Amherst, 
Mass., numerous 
pretty tubes such as 
are figured in the ad- 
joining engraving. 
The larva; probably 
in August and early \ 
in September, gath- 
ers together about 
fifteen needles of the 
white pine, tying 
them into a bundle 
by silken threads ; 
then, usually eating 
off about one-third 
of the ends, forms a 
tube, within which Fre. 85.—Tubes of the pine tube-building leaf-roller; natural size.—

Some full-grown larvee were found September 22 which had gathered 
the leaves togéther without cutting them off, the tube extending the 
whole length of the leaves. It is possible that the larve of the first 
_brood early in sammer cut off the ends of the tube, while the approach
