INSECTS INJURING OAK-LEAVES. 189 
on the under side with white. Fore wings long, outer edge very oblique, snow- 
white as a ground color ; basal third white, mottled with deep brown, especially on 
the costa. The middle third of the wing brown, bordered with the black basal and 
extradiscal lines. The basal line is deeply and regularly curved outward ; the extra- 
discal line is irregularly and deeply scalloped ; it runs straight from the costa to the 
great angle on the median line through two deep scallops ; the angle is jagged and 
sharp, and below the line forms a great curve, sending a point outward on the in- 
ternal vein. Beyond this line the wing is white, with scattered dark specks, and 
with a ferruginous patch just below the sixth subruedian, and a larger one extending 
from the second median venule to the inner edge of the wing near the angle. Hind 
wings white, more or less densely mottled with brown on the inner two-thirds ; the 
extradiscal line is zigzag, with a large angle in the middle of the wing. Beyond 
this the markings repeat those of the fore wings. Expanse of wings 5.5 mm . 
264. Aplode8 mimosaria Guene"e. 
This has been bred from the oak by Mr. Walsh in Illinois, while Riley 
has found it feeding on the oak at St. Louis, Mo., July 31. It is com- 
mon in the New England and Central States. 
Larva.- Larva ten-footed, cylindrical, its dorsum with curved lateral appendages 
covered with short velvety hairs, and similar to those of Limacodes ? hyalinus Walsh, 
except that they are much shorter and none of them abruptly longer than the others. 
Of a dingy-brown color, and, including the appendages, about one-fourth of an inch 
in diameter. (Walsh.) 
Pupa. — The pupa is of a pale ocherous-brown color, varied with reddish-brown, 
with many fuscous dots, especially along the nervures of the wing-cases, and with 
the caudal spine simple. It measures 0.43 inch, including the spine. (Walsh.) 
Moth.— Four males and females. A rather large species, with the antennae moder- 
ately well pectinated. Apex of fore wings square, outer edge not very convex. 
Hind wings well rounded, less angulated than usual; anal angle square. Body and 
wings of the usual pale-green color ; head and antennae white, front bright rose- 
colored except on front border. Palpi white ; end of second joint and under side of 
third joint roseate. Both pairs of wings crossed by linear, slightly waved, white 
lines. Inner line on fore wing, very near the base of wing, regularly curved; outer 
line straight, waved, parallel with outer edge. Costa narrowly edged with white. 
Fringe white on both wings. Hind wings with the inner line nearer the base of 
wing than on fore wings, curved regularly. Outer line bent outward in the middle, 
the line not so wavy as on fore wing. Beneath both lines faintly reproduced (not 
(i avec une seule ligne blanche," asGuen6e says). Hind wings and posterior two- thirds 
of fore wings whitish-green. Outer side of fore femora green, of tibiae dull red ; 
two posterior pairs white. Abdomen white, green at base above, with a conspicuous 
white spot at base. Expanse of wings 1£ inches. Length of body, male 0.45, 
female 0.40. 
265. Petrophora diversilineata Hiibner. 
Professor Riley found, May 10, at St. Louis, Mo., larvae of this spe- 
cies feeding on laurel-oak and elm. Others were found on pear, apple, 
cherry, and rose. They are of a deep, rich brown above, sulphur-yel- 
low at sides, and pale beneath. All had entered the ground by June 5, 
The moths issued November 9. (Unpublished notes.) 
EQO- — Cylindrical, much rounded, and fuller at the posterior than at the anterior 
end, which is truncated and contracted, with a swollen vein ; white, with the sur- 
face granulated.
