obscure streaks from the middle to the tip. Hind wings fuscous. In orna- 

 mentation, this insect is much like E. f a s c i a t a n a. 



The larva is of a dull amber-brown color, with papilliform points, somewhat 

 darker; head and shield blackish brown. Tt inhabits the pear and plum tree. 

 One of the leaves of a terminal shoot is cut off at the base of its leaf-stalk, lined 

 with silk, and folded ; other leaves are attached to this, and it is used even 

 after it has become dead and blackened, as a place of concealment. The 

 larva may be taken in April and May, and becomes an imago early in June. 



H. Scudderiana. Fore wings with a rather small dark brown basal 

 patch, with the edge obliquely inclined to the base, and rather wavy, broadly 

 white in the middle, and somewhat mottled with brownish ; dark brown and 

 white in the apical portion. Along the edge of inner margin is a row of dark 

 brown dots from the base. The costa geminated with yellowish from the 

 middle to the tip. Above the inner angle, is a white ocelloid-like patch, en- 

 circled irregularly with bluish. Hind wings fuscous.

Bactra ? Stephens. 



Fore wings with the costa regularly arched, rather abruptly near the tip. 

 which is acute, but not produced ; hind margin truncate from the tip, inner 

 angle rounded, inner margin nearly straight. Wing structure as usual ; disk 

 rather narrow, without secondary cell. Hind wings broader than the fore 

 wings, hind margin regularly curved from the tip to the basal angle ; branches 

 of the subcostal connivent; discal vein curved; the medio-discal, and the two 

 superior branches of the median, from a common point. 



Head scarcely smooth. With ocelli. Antennae setaceous, pubescent. Palpi 

 very little exceeding the face, cylindrical, slightly, ascending ; middle joint 

 thickened with scales beyond the middle ; apical joint very minute. Tongue 

 wanting. 



B. ? argutana. Fore wings ochreous, tinted with reddish brown, and 

 striated with the same hue toward the base, and with dull purplish from the 

 middle to the tip. Above the inner angle is an indistinct ocelloid patch, con- 

 taining two black spots, with a dull, silvery streak exterior to them, and the 

 wing varied with purplish interiorly to it. The costa is streaked with pale 

 ochreous with dark centres, the third from the tip giving rise to a very oblique 

 purplish streak. Hind margin more or less yellowish behind the ocelloid patch 

 and at the tip. Hind wings fuscous or pale ochreous. 



I am well assured of the accuracy of my notes, and yet I find the record of the 

 larval state of this insect quite anomalous : at least, the imagos produced from 

 three larva, which one would declare distinct, are not to be distinguished from 

 each other. One rolls the leaves of witch hazel into conical cornets, and 

 binds the rolls with strong and numerous bands. It prepares for pupation by 

 turning down a portion of the leaf. Its body is concolorous reddish, except a 

 few spaces between the anterior rings, where it is pale brown; shield reddish; 

 head pale brown. Another feeds on the leaves of sumach, rolling a leaf 

 spirally in the first place, securing the rolls with bands, and afterwards joining 

 the neighboring leaves to the one first inhabited. Its body is of a dirty green- 

 ish color, with obscure whitish papilliform points. Head whitish, or with a 

 pale brown head and green body, striped with dark green. The third feeds on 

 the leaves of black thorn and elm, drawing them into a fold from the base, and 

 binding it to the midrib. It is concolorous lemon-yellow, with a yellowish 

 brown head. The differences in color may be reconciled by the supposition, 

 that the descriptions represent different periods in larval life; but if my notes 

 are correct, it is difficult to account for the difference in habits, as shown in 

 the third individual, which agrees in this respect with the larvae of the genus 

 Anchylopera.
