INSECTS INJURIOUS TO THE PINE. : 203 
. The transformations of this moth were first described by Harris, but 
the earlier stages have more recently been fully described by Mr. Lintner, 
in his Entomological Contributions, No. I. Though usually feeding on 
the white pine in the New England States, where we have seen it in the 
breeding-cages of entomological friends, it also feeds on the oak, button- 
wood, ete., and will eat the leaves of the chestnut. It is too rare to be 
of any economical importance, but will always attract the attention of 
lovers of fine, rare insects. The moth laysits eggs late in June, hateh- 
ing in about a week or ten days; the larva, according to Lintner, molting 
at least four, if not five times. 
Larva.—Three or four inches long and more than half an inch in diameter, and for 
the most part of a green color, slightly tinged with red on the back, but many of them 
become more or less tanned or swarthy, and are sometimes found entirely brown. There 
are a few very short hairs thinly scattered over the body; the head and the legs are 
pale orange colored; the oval spiracles are large and white, encircled with green; on 
each of.the rings, except the first, there are six thorny knobs or hard and pointed 
warts of a yellow color, covered with short black prickles; the two uppermost of these 
warts on the top of the second and of the third rings are a quarter of an inch or 
more in length, curved backwards like horns, and are of a deeper yellow color than 
the rest; the three triangular pieces on the posterior extremity of the body are brown, 
with yellow margins, and are covered with raised orange-colored dots. (Harris. ) 
The pupa.—Subterranean, not contained in a cocoon, about two inches long, of a 
dark chestnut-brown color, rough, with little elevated points, especially in front: the 
end of the body with a long forked spine, and surrounded, on eachring, with a notched 
ridge, the little teeth of which point towards the tail. Three of the grooves or incis- 
ions between the rings are very deep, thus allowing a great extent of motion to the 
joints, and these, with the notched ridges and the long spine at the end of the body, 
enable the chrysalis to work its way upward in the earth, above the surface of which 
it pushes the fore part of its body just before the moth makes its escape. (Harris. ) 
The moth is ocher-yellow, spotted with purple-brown, witha large patch at the base, 
a small round spot near the middle, and a broad, wavy, light purple-brown band 
toward the outer edge of each wing; in the males there is another purple-brown spot 
covering nearly the whole of the outer hind margin of the fore wings, and united to 
the band near that part; the boay is yellow, washed with purple-brown along the 
back. It expands from four and a half to over five inches. (Harris. ) 
76. Citheronia sepulcralis Grote and Robinson. 
Closely allied to C. regalis is the above named species, whose cater- 
pillar feeds on the pine. It is closely allied to the larva of C. regalis, but 
the horns on the three thoracic segments are paler, slenderer, and uni- 
colorous, “the lower lateral pair on the third and fourth segments appa- 
rently greatly reduced; the specimens not being quite perfect prevents 
certain accuracy as to this latter statement.” (Grote.) It is possible 
that this will be found to be a variety of C. regalis. 
77. THE WHITE PINE TUFTED CATERPILLAR. 
Platycerura furcilla Packard. 
Found rarely iff September on the white pine, a dull-red caterpillar, banded with 
brighter red; a white lateral line, with reddish hairsin clusters, and on the Lst, 3d, 4th, 
and 11thsegments two long pencils of red hairs; spinning a cocoon among fallen leaves, 
the gray moth appearing about the middle of June.
