202 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
lated, flattened anteriorly, subtriangular, with an impressed medial line, and straight, 
yellow lateral lines terminating at the apex in two black granulations, and bordered 
interiorly above with black. Body grass-green. Subdorsal and lateral bands yellow. 
Substigmatal stripe bordering the stigmata, white, enlarged on the central portions 
of the segments. Between the subdorsal and substigmatal stripes, on the fourth and 
fifth segments ventrally, and exteriorly to the legs and prolegs, dotted on the seg- 
ments with paler green or yellow. On the vascular line a series of crimson spots on 
the front of the segment, beginning usually on the fourth, the first small, sometimes 
double, the anterior ones triangular or lozenge-shape, regularly increasing in size and 
extending over more of the segment, the posterior ones quadrangular, and uniting on 
the last two segments in a stripe. A ventral stripe of rose color, beginning at the 
third pair of legs, widening as it proceeds, and embracing the prolegs. No caudal. 
horn. Caudal shield granulated and edged with white. (Lintner, Proc. Ent. Soe.,- 
Phil., iii, 669.) 
Pupa.—Chestnut-brown, with a rough, not produced head-case. Tongue-case 
buried, parting the leg-cases, but terminating just before reaching the tips of the 
wing-cases. Incisures rounded. Posterior segments tapering. Stigmata black, ter- 
minal spine black, contracted at base, minutely bifid. Length,.95-1.10 inch.- (Lint- 
ner, ) 
74. THE CHECKERED PINE SPHINX CATERPILLAR. 
Ellema pineum Lintner. 
A eaterpillar like the foregoing, but with a dorsal row of squares, and transforming 
to a moth which is readily distinguished from Hllema harrisii by the darker ground- 
color of its wings, the absence of the gray shades, and its much less distinct markings. 
(Lintner. ) 
Mr. Lintner, in his Entomological Contributions contained in the 25d 
teport of the New York State Cabinet, describes the male and female 
of this pine sphinx, and also describes the larva as follows: 
Larva.—Length twoinches. Color grass green. Head subtriangular, 
green, bordered with bright yellow, within which, at the apex, is a A 
of black. Body subeylindrical, tapering at the extremities, and with- 
out a caudal horn. Dorsally, a reddish-brown line interrupted on the 
hinder portion of each segment by a square of green traversed by diag- 
onal lines; a subdorsal yellow line borders the above; lateral stripe 
yellow; substigmatal stripe white, interrupted at the sutures by light 
green; ventral stripe and prolegs rose-red. Feeds on the white pine, and 
matures about the middle of September, when it enters the ground and 
forms a cell, where it becomes a chrysalis. 
75. THE LARGE SPINEY CATERPILLAR. 
Eacles imperialis (Drury). 
Order LrpipoprEera; family BoMBYCID.®. 
Among the leaves of the white pine in the Northern States, late in August and 
through September, a large, thick, pale-green caterpillar between three and four inches 
long, with the head and legs pale orange, with six thorny, yellow knobs behind the 
head; pupating in the ground and changing late in June to alarge, handsome, yellow 
moth, speckled with brown, and with a very light purple-brown band across the 
outer margin of each wine.
