ning two leaves together, within which they remain concealed. The 

 leaves are in no wise folded, but two naturally overlapping ones are 

 united by several short, stout cross-bands of silk. The larvje feed only 

 on the undermost leaves, and on account of these habits there is no sign 

 of their presence on the bushes, unless one attempts to separate the ap- 

 parently simply overlapping lea\'es. 



Egg. — Laid two to seven together on the under side of a leaf; ellip- 

 tical, much flattened above and below, reticulations narrow, regular, 

 somewhat rounded, with short pile at the angles. The surface of the 

 cells between seems smooth. Color pale whitish green, shining. Size 

 .yx .5X .4 mm. 



Larva. — Head bilobed, rounded, clypeus large, shining, sha- 

 greened; color whitish, jaws and a shade below apex of each lobe in 

 front yellovv brown ; two trans\erse bands connected by a strong band 

 on the side of the head behind ocelli ; lower band from base of jaw to 

 ocelli, upper above clypeus, but obsolete centrally in the yellow cloud 

 below apex. Body flattened, thoracic feet small, colorless, hairy below ; 

 abdominal feet on joints 7-10, normal as to the crotchets on the inside of 

 the planta, but about six occur also on the outside ; the inner row is dense, 

 the hooks of different lengths, while those on the outside are single and 

 remote ; no anal feet, the fleshy plate produced into a short conic pro- 

 cess. Set^ fine, short and very obscure, except at the extremities. 

 Body smooth, translucent whitish with a green shade dorsally especially 

 in the dorsal vessel; tracheal line evident by transparency, white ; cervical 

 shield hemispherical, whitish, shining, a gray shade at the lateral corners. 

 Above and before the spiracle on joint 2 is a shining black elliptical 

 spot, bearing two setce, suggesting a parasitic attack to which this in- 

 sect is subject. 



Pupa. — Formed between leaves on the ground, with a few silken 

 threads. When leaving the bushes to pupate the lar\'je become suffused 

 with reddish pink on the back. The pupa is dark brown, a little black- 

 ish tinged on the more exposed parts and especially on the veins of 

 the wing-cases ; a patch of white bloom on the collar and vertex of 

 head. Three movable incisures. Length 10 mm. 



Found commonly in the Adirondacks, White Mountains and in 

 Western Maine. 



Eudeilinea is the most generalized form of our Drepanids, and if 

 we adopt Prof. Comstock's family Auzatidre, in which he places this 

 genus, we may use its characters to define the family from the larva. 

 The Auzatidaj then agree with the Drepanid^T in all essential respects,
