INSECTS INJURING OAK-LEAVES. 191 
body resembles E. luteata, being somewhat flattened. These caterpil- 
lars differed from those bred from the bush juniper at Salem, Mass., 
in wanting the lateral white line. The specimen bred was compared 
with those from different States in the National Museum by Mr. John 
B. Smith and myself. It seems to feed ou evergreens northward and 
in Florida on oak, and may be a general feeder. 
Larva. — Pale green; body covered with fine papillae. Prothoracic segment much 
swollen transversely; no marking except a brownish linear dorsal line. This was 
the young of the moth which issued April 20. 
Another larva, whose moth emerged April 30, was more typical. Body somewhat 
flattened, with a dorsal series of sharply pointed dark-brown patches, the points ex- 
tending into the narrow linear brown dorsal line. On the thoracic segments a lateral 
broken heavy dark line, each becoming a pale narrow thread on the abdominal seg- 
ments. Length, 18 mm . 
Pupa.—O). 
Moth. — This is our most common pug-moth, and may be distinguished by the 
pointed fore wings, with the numerous transverse lines bent sharply outward, the 
extradiscal line forming a sharp angle opposite the discal dot, and notched inward 
on the subcostal vein ; by the distinct submarginal wavy white line, ending in a large 
white twin spot at the inner angle; by the fine dark lines on the hind wings, and by 
the heavy black costal spots and marginal lines on the under side. The fore wings 
expand 20 mm . 
267. THE OAK-LEAF ROLLER. 
Tortrix quercifoliana Fitch. 
In the early part of June, says Fitch, the sides of particular leaves 
may be found to be curved upward and drawn slightly together by 
silken threads, beneath which lies a slender, grass-green leaf-roller, 
which finally pupates in the end of the leaf, the moth appearing in 
New York about the 1st of July. 
While at St. Augustine, Fla., early in April, I noticed a pale green 
leal-roller on the live oaks ou Auastasia Island. April 14 it spun a 
slight cocoon, within which the worm changed to a pupa April 16 or 
17 ; the moth appeared April 30, after my return to Providence. 
Larva.— Grass-green throughout, body tapering slightly posteriorly, but less so 
towards the head. Head round, slightly flattened, and "as thick as the neck into 
which it is sunken." Length 19 mm (0.75 inch). 
Pupa. — Body pale and slender, the cast skin thin and unusually so for a Tortrix. 
Cremaster or terminal abdominal spine peculiar in being long and narrow, as wide at 
the tip as at the base ; the surface above and beneath with fine longitudinal ridges ; 
a pair of short dorsal set* near the end ; edge of the extreme tip curvilinear, with 
four curved setae of nearly equal length. Each abdominal segment with two rows 
of fine teeth. Length, 10 mm . 
Moth. — Pale tawny yellow, with yellowish brown darker scales and dots and darker 
brown lines. Head pale, tawny brown on the vertex, with a small spot in the middle 
of the front. Palpi dark, externally pale above and at tip of second joint. Fore 
wings pale whitish tawny yellow, densely speckled with darker scales ; on the inner 
third of the wing an oblique, dark brown, narrow line beginning on the inner third 
of the costa and ending in the middle of the hind margin. An outer parallel line, 
which is forked on the costa and ends on the internal angle ; from near the middle
