INSECTS INJUKING OAK-LEAVES. 191 



body resembles U. luteata, being somewhat flatteued. 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 on evergreens northward and 

 in Florida on oak, and may be a general feeder. 



Larva. — Pale green ; body covered with fine papillse. 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™°^. 



Pitjja.— (?). 



Moth. — This is our most common pug-moth, and may be distinguished by th& 

 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 hiud wings, and by 

 the heavy black costal spots and marginal lines on the under side. The fore wings 

 expand 20™™. 



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 Ist of July. 



While at St. Augustine, Fla., early in April, I noticed a pale green 

 leaf-roller on the live oaks on Anastasia 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. 



Zarua.— 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'"'" (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 setie 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'""'. 



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
