INSECTS INJURIOUS TO THE PINE. 201 
Below, and arising from each side, is a long, corneous, three-jointed, slender out- 
stretched appendage of the size and form of the antenne. The under side of the 
body is mottled with greenish and reddish as above, with a reddish medium line. On 
the side of the thorax are two rows of dots, and two rows along the middle on the 
ventral side of the three thoracic wings.

71. THE PINE THECLA. 
Thecla niphon (Hiibner). 
Order LEPIDOPTERA ; family PAPILIONID®, 
Feeding upon the leaves in summer, a flattened oval worm, 0.75 long when full 
grown, of the same deep green color as the leaves, with a light yellow stripe along 
the middle of its back and a white one on each side, and a brown head; changing to 
a short thick grayish pupa with two rows of small blackish spots, and outside of these 
a row of more conspicuous rust-red ones, which is attached by its tail and by a thread 
around its middle in form of a loop; giving out a smallish butterfly which comes 
abroad in April and the fore part of May; 1.00 to1.15 in width across its wings, which 
are of a dusty rust color and without spots above, paler grayish beneath, the fore 
ones with a dislocated black band beyond the middle, edged on its hind side with 
snow white, and beyond this a row of black crescents, each with a white spot in its 
concavity, and the hind wings similarly but more complexly variegated. (Fitch.) 
Boisduval says, “ This insect lives in Georgia and Florida, on several 
species of pine, and is very rare and seldom seen in collections.” It, 
however, is a common species in the State of New York, in all our for- 
ests where pine trees abound, coming out with the first warm days of 
spring, before collectors are much abroad in search of insects, and con- 
tinuing but a short time. (Fitch.) 
72. THE SOUTHERN PINE HAWK-MOTH. 
Ellema coniferarum (Smith). 
Order LEPIDOPTERA; fathily SPHINGID. 
Feeding on the pine in the Gulf States, a caterpillar with a short caudal spine, the 
body checkered with brown and white spots, with a dorsal whitish line; entering the 
earth to transform into a small gray sphinx moth, closely resembling the two follow- 
ing northern species. (Harris.) 
73. HARRIS’ PINE HAWK-MOTH. 
Ellema harrisii Clemens. 
A grass-green caterpillar with no caudal horn, but a caudal plate granulated and 
edged with white, with yellow subdorsal and lateral bands, and a white stripe bor- 
dering the stigmata; becoming fully bred and leaving the white pine about the mid- 
dle of September, the pupa subterranean, and the moth appearing about the middle 
of June in New York. (Lintner.) 
The different pine hawk-moths are of little economic importance, as 
they are of great rarity both in the caterpillar and moth states; but 
from a scientific point of view these moths possess much interest. 
Larva.—2 inches long, .23 inch broad. Subcylindrical, tapering slightly ante- 
riorly, and the last two segments quite tapering. Head, size of first segment, granu-
