856 PROCEEDINGS OP THE ACADEMY OF 



costal veins are distinct to the base, the latter forked near the tip of the wing; 

 discal vein arising uear the middle of the wing, and curved; medio-discal on 

 a very short stalk ; the two superior branches of the median from a common 

 point. 



Head scarcely smooth. Ocelli small. Face narrow, rough. Antennae ap- 

 proximated setaceous, pubescent. Palpi exceeding the face scarcely one-fourth 

 their length, slightly curved, rather slender, and somewhat hairy ; middle joint 

 truncate, somewhat thickened at its end with scales; apical joint slender, 

 apparently very minute being almost concealed by the terminal scales of the 

 middle joint, but when denuded, at least one-half as long as the middle. 

 Tongue slightly longer than the palpi. 



S. peri tan a. Brownish ochreous. Fore wings paler on the costa at the 

 base than the inner margin ; with a brown central fascia inclined to the inner 

 angle from about the middle of the costa, edged internally with pale yellowish ; 

 this band is usually rather broad, but sometimes narrow. Near the tip, on the 

 costa, is a dark brownish spot, with a line extending from it to the inner angle. 

 Costa with a few minute brown points. Hind wings rather dark grayish. 



Exartema. 



Fore wings with the costa regularly arched ; tip obtuse and rounded ; hind 

 margin rounded, very slightly oblique ; disk with secondary cell. Hind wings 

 rather broader than the fore wings; obtusely angulated on the hind margin, op- 

 posite the median nervules ; inner margin deeply and sharply excised, with a 

 cylindrical appendage along the inner margin from the base, the lower 'portion of which 

 is free; the branches of the subcostal are connivent ; medio-discal arising on 

 a short stalk at the bifurcation of the two superior branches of the median ; 

 discal vein curved. 



Head rough. With ocelli. Tufted between the antenna?. Face smooth, 

 rounded. Antennae setaceous, pubescent beneath. Palpi arched, applied to the 

 face with the tips equal to the base of antennas; with rather hairy scales be- 

 neath from the base to the tip of middle joint, which is slightly scaly at the 

 tip above ; terminal joint minute, ovate, distinct and smooth. Tongue about 

 equal to the palpi. 



E. n i t i d a n a. Palpi yellowish white, terminal joint fuscous. Fore wings 

 dull sordid crimson, with a pure brown basal patch divided into two portions, 

 one a streak above the median vein, the other a patch beneath it, slightly 

 varied with reddish brown. The central fascia is pure brown, with an irregu- 

 lar internal edge, and externally subdivides into three broad streaks or projec- 

 tions ; that on the inner margin truncate at the inner angle, one in the middle 

 of the wing, and one near the costa acute. Slightly connected with the upper 

 streak, is a curved one of the same hue, varied with reddish brown, running to 

 the middle of the hind margin ; all these streaks are bordered with ochreous. 

 The costa is streaked with reddish brown. Hind wings dark fuscous. 



E. permundana. Palpi dull yellow, apical joint fuscous. Fore wings 

 with a large dark brown basal patch, varied with testaceous or yellowish. 

 The central fascia is dark brown, varied with testaceous, and is separated 

 from the basal fascia by a yellowish band, containing dull silvery scales, or a 

 tarnished silvery band ; exteriorly, the fascia throws off three more or less 

 distinct, short, rounded projections, two near the middle of the wing, and the 

 other at the inner margin, with a triangular patch exterior to the latter; from 

 the costa, near the tip, is an oblique, dark brown band, varied with testaceous 

 scales, to the hinder margin, beneath the middle. The interspaces between 

 these markings is filled up with yellowish, somewhat silvery-hued, or with 

 dull, tarnished silvery hue, and the markings are edged with yellow. Costa 

 with yellowish white streaks, with central dark brown streaks. Hind wings 

 dark fuscous.
