204 INSECTS INJURIOUS TO FOREST AND SHADE TREES. ~ 
This is another interesting caterpillar, whose history has been traced 
by Mr. Lintner. The worm, when in the attitude of feeding, with its 
terminal pair of legs clasps the leaves at the sheath, and extends its 
body along a leaf until it commences to bend, when, by detaching suc- 
cessively the first and following pair of prolegs, it forces the leaf through 
its legs until its tip is held between them. The caterpillars spin their 
cocoons beneath leaves lying in the bottom of the breeding-cage, the 
moth emerging June 12. It is interesting to see that this, like several 
other caterpillars of the pine in this country and Europe, are colored 
red like the pine shoots, and are thus perfectly protected from their 
enemies. 
The caterpillar is an inch and five-eighths long. Head round, of about the diameter 
of the body, red, with conspicuous markings upon the front of lighter red, somewhat 
in the form of a script z, and less distinct reticulations of the same. Body presenting 
a peculiarly mottled appearance from its irregular and broken stripes; its general 
color dull red; on each segment an irregular band of brighter red; a whitish vascular 
line within a broken gray stripe; a better defined lateral stripe just above the stig- 
mata, within which, on each segment from the third to the eighth inclusive, are four 
black depressed spots arranged in a right angle, the upper three in line, the largest of 
which rests on the crown of the segment, with two behind it and one before; the sub- 
stigmatal fold is white on the anterior portion of each segment and red on the remain- 
der ; rows of tubercles, from which clusters of red hairs of unequal length proceed, 
which, on the anterior segments, incline to yellow; on the Ist, 2d, 4th, and 11th seg- 
ments each, superiorly, are two pencils of red hairs, nearly + inch in length, darker 
at the tips, and slightly feathered. These pencils made their appearance after the last 
molting. Stigmata encircled with brown. Legs red. (Lintner.) 
The moth has, compared with other Notodontians, rather broad triangular fore w ings, 
rounded hind wings, the front of the head being rather broad and smooth, while the 
antenne are rather long and pectinated. It is ash-white, peppered with dark scales; 
the fore wings are crossed by a twice angulated basal black line, and near the inser- 
tion of the wing is a black spot. A second straight line crosses the wing just before 
its middle, and from it branches at nearly right angles a line which becomes straight 
above the second median nervule and parallel to the inner line, thus inclosing a large 
square area which is concolorous with the rest of the wing. There is a submarginal 
obscure line shaded with white externally, which is irregularly zigzag, and runs 
down more than usual in the second median interspace toward the margin of the Ww ing. 
Length of body, .65 inch; expanse of wings, 1.50 inches.

. THE PINE PARORGYIA. 
Parorgyia parallela Grote and Robinson. 
Order LEPIDOPTERA; family BOMBYCIDZ.

Occasionally found feeding during June and also in October on the pine, a caterpillar 
tufted like the vaporer moth (Orgyia leucostigma), but with mouse-colored feathered 
hairs; the pencils black; cocooning July 5 and the moth appearing July 21. (Lintner. ) 
The following account of this not common insect is taken from Lint- 
ner’s Entomological Contributions, iii. He has found it on the plum, 
and on one occasion (September 24) on the pine. His description was 
based on specimens reared in the breeding-cage from eggs laid July 25 
in confinement. They developed fully by the first week in November,
