INSECTS INJURING OAK-LEAVES. 183 



Half-way between the metathoracic legs and the first pair of filaments are two sub- 

 acute tubercles, which are rust-red; when the four filaments are uncurled they are 

 as long as from the head to the tubercles. The anterior pair of filaments are pale 

 rust- red beneath at base, brown above, but tipped with white. A distinct dorsal 

 line from the prothorax to the second pair of filaments ; a pair of small tubercles 

 next to the last segment, tipped with pale rust-red. Body wood-colored above and 

 beneath ; thoracic segments greenish above, succeeded by pale rust-red between the

tubercles and first pair of filaments ; behind these variously marked with light and 

 dark brown. An oval dark spot behind the last pair of tubercles and extending into 

 the anal plate. Anal legs rusty, lined above with a whitish line. Length 18™™. 



Pupa. — Body rather thick, conical, pale horn-brown, slashed and speckled with 

 dark-brown. 



Moth. — Fore wings unusually short and broad; apex rectangular, outer edge bent 

 in the middle, deeply excavated in the female on each side of the angles ; liind wings 

 rounded at the apex, with a distinct angle in the middle, reaching as far as the end 

 of the abdomen. Pale ocherous, with brown veins and transverse dots ; a brown 

 inner line, much curved. An outer sinuate line, with a supplementary line just 

 inside, touching the outer line on the submedian vein and in the extradiscal space, 

 and forming a large circle, one side of which touches the outer line. Beyond the 

 line the border of the wing is dull brown, with the apical region clear. Hind wings 

 streaked transversely, as on the fore wing, with the outer third brown, the apex 

 included. Expanse of wings 25""" (1 inch). 



256. Endropia hilinearia Packard. 



The geometric caterpillar of this species was found by Mr. W. Saun- 

 ders, of Loudon, Canada, feeding on the oak ; unfortunately it was 

 not described ; it became 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 betwewi 

 this line and the outer edge of the wing is a difi"use, interrupted, faint grayish band 

 with a few dark scales, often wanting, and connecting with an oblique apical patch, 

 also concolorous with the front edge of the wing. Outer edge of the wing deeply 

 notched, the eight acute points (including the apex, which is very acute) tipped with 

 a few black scales, the fringe being whitish between. Beneath, body and wings 

 ocher-yellow, especially in the middle of the wings. Both wings marked alike with
