below the middle on a moderate vertical stalk. Median vein with the two 

 superior nervules arising at a common point. 



Head rather rough, with ocelli. Face broad, rounded. Antennae setaceous, 

 simple. Palpi a little longer than the head, slender, cylindrical and slightly 

 scaly beneath, separated and slightly curved ; terminal joint distinct, cylindri- 

 cal and obovate ; middle joint curved, slightly scaly beneath. Tongue equal 

 in length to the labial palpi. 



S. i n ters t inct ana. Palpi whitish. Head and thorax dark brown. 

 Fore wings dark brown, with a curved white, somewhat silvery dorsal streak 

 divided in the middle by a dark brown line and a rather faint silvery streak at 

 the inner angle. The costa from near the base to the tip is streaked with yellow- 

 ish white, slightly silvery-hued. Hind wings dark brown, along the costa in the 

 middle, white. 



Halonota Stephens. 



Fore wings with costa regularly arched, but not broad at the base, with a 

 fold at the base in the r^; tip rather acute, hind margin rounded, slightly indented 

 beneath the tip. The disk is rather above the middle of the wing, with a 

 moderate secondary cell and the fold distinct ; the discal vein straight. In the 

 hind wings the costal and subcostal veins are distinct at the base ; the lower branch 

 of the subcostal vein is separated from the upper and is borne on a short nearly 

 straight stalk ; discal vein angulated, giving rise below the middle to a 

 disco-central vein on the nearly vertical stalk. Median with the two superior 

 nervules arising from a common stalk. 



Head scarcely smooth, with large ocelli. Face moderately broad, rather 

 naked beneath the middle. Antennae setaceous, minutely pubescent beneath. 

 Palpi exceeding the face by nearly one half their length, moderately remote, 

 applied to the face and thence porrected, rather broad with spreading scales 

 at the tip of the middle joint above and almost tufted at the tip beneath ; 

 terminal joint slender, drooping somewhat, and nearly as long as the middle 

 joint, but partly concealed in its terminal hairs. Tongue as long as the labial 

 palpi. 



H. simulana . Palpi dull ochreous, fuscous at the tip. Head brownish 

 ochreous. Fore wings brown with a slight brassy hue, with an ochreous, 

 dorsal blotch plain in the rj 1 and striated with brownish in the 9 Costa 

 streaked with ochreous, and with two slightly violet hued streaks from the 

 costa, one running beneath the tip and the other to a faint ocelloid patch, 

 behind which on the hinder margin are three black spots. The apical portion 

 of the wing is varied with ochreous. Hind wings fuscous, white on the costa. 



Dr. Morris. Baltimore and Easton. 



A. i n c a n a n a. Palpi white. Head dark gray. Fore wings dark brown, va- 

 ried with whitish along the inner margin toward the base, with an oblique dorsal 

 white patch, terminating in the ocelloid patch, with a slender, irregular dark 

 brown line on its middle, and one or two spots on the dorsal edge of the wing. 

 The costa is streaked with white, slightly silvery ; beyond the middle of the 

 wing are one or two purplish-hued lines, one of which round the ocelloid 

 patch, where it_ becomes somewhat diffuse. The ocelloid patch is ochreous, 

 with three black streaks, and is placed nearly in the middle of the apical 

 portion of the wing, with a white spot adjoining and beneath it. Hinder 

 border with three or four terminal black spots above the inner angle. Hind 

 wings dark fuscous, grayish towards the base. 



Ephippiphora Duponchel. 



Fore wings rather narrow ; costa regularly arched ; tip obtuse ; hind margin 

 rounded or slightly sinuous. The wing structure as usual. In the hind wings 

 the costal and subcostal are distinct to the base ; the branches of the latter
