INSECTS INJURIOUS TO THE OAK. 49 
49, THE HARLEQUIN OAK GEOMETER. 
Aplodes mimosaria Guenée. 
Order LEPIDOPTERA; family PHALZNID®. 
Feeding upon the leaves of the oak, a cylindrical brown geometric caterpillar, its 
back with singular curved lateral appendages, covered with short, velvety hairs, 
changing to a pale yellowish browner pupa, with a simple caudal spine, nearly 4 an 
inch long. (Walsh). 
The moth.—Male antenne moderately pectinated, body and wings pea green, the wings 
broad, the hinder pair well rounded, less angulated than usual, anal angle square; 
head and antenne white; front of the head bright rose-colored, except along the 
front edge. Palpi white, end of second joint and under side of the third joint roseate. 
Both pairs of wings crossed by linear, slightly-waved white lines. Inner line on the 
fore wings very near the base, regularly curved; outer line straight, waved, parallel 
with outer edge. Costa narrowly edged with white. Fringe white on both wings. 
Outer side of the fore femora green, of tibix dull red; two posterior pairs of tibie 
white. Abdomen white, green above at base, with a conspicuous white spot at base. 
Expanse of wings, 14 inches. Ranges from New England to the Middle and Western 
States. 
50. THE LARGE SCALLOPED WINGED GEOMETER MOTH. 2 
Stenotrachelys approximaria Guenée. 
In the Southern States feeding on the oak a large geometer whose body is ash gray, 
washed with brown, wiih a dorsal series of white lozenges, lined with black and tray- 
ersed in their middle by a twin, interrupted black vascular line. Found in March 
and April, the moth remaining in the chrysalis. 
This caterpillar, according to Abbot (in Guenée), lives in Georgia on 
Similax rotundifolia and laurifolia, and, according to Abbot, on Quercus. 
This species is known to inhabit North Carolina as well as Georgia. 
The moth.—It may be recognized by the deeply scalloped wings, and the large head, 
which is rather swollen in front. It is whitish gray, the wings clear, not bordered 
with brown. The fore wings with two distinct, heavy, black lines, the inner very 
near the base of the wing, regularly curved, alittle pointed on the costa. Outer line 
bent at right angles on the basal third of the first median vein, the line thence going 
straight to the costa, though zigzag in its course; from the rectangular bend, the line 
follows a course subparallel to the median line, where it again turns rectangularly, 
ending on the middle of the inner edge of the wing. An inner reddish-brown line is 
parallel and near it below the median vein, and above passes just within the faint 
discal dot. Beyond this line the wing is speckled with transverse short, linear spots. 
A scalloped marginal, distinct black line. Expanse of wings, 1.90 inches. 
51. THE TWO-LINED OAK GEOMETER MOTH. 
Endropia bilinearia Packard. 
A geometric caterpillar feeding on the oak; becoming a chrysalis early in July, 
emerging as a moth two weeks later. 
The moth.—Clear fawn-brown ; wings much darker and less spotted than in the other 
species of Endropia. Body and wings concolorous ; front edge of the fore wings paler 
than the rest of the wing and spotted finely, especially on the edge, with brown 
specks. Two brown hair-lines, the inner situated on the basal, and the outer on the 
outer third of the wing; the inner line bent on the front edge of the wing. Outer line 
a little curved outward in the middle of the wing. Half-way between this line and 
the outer edge of the wing is a diffuse, interrupted, faint grayish band with a few 
dark seales, often wanting, and connecting with an oblique apical patch, also con- 
<olorous with the front edge of the wing. Outer edge of the wing deeply notched,
