AMERICAN EEPIDOPTEEA. 11 



A. dyarellit n. sp. — PI. I, fig. 1. — Grayish to dark fuscous. Labial palpi 

 and lateral setae dark fuscous, brush of second joint and the third joint dull och- 

 reous, the latter flattened with a dark spot beneath and dusted with fuscous above. 

 Face ochreous white. Vertex brownish, intermixed with white anteriorly. 

 Thorax brown, patagia paler. Forewings moderately wide, costa evenly arched 

 from base to apex, latter broadly rounded; grayish fuscous, spotted with seal- 

 brown as follows: three transverse costal spots near the base, the first and thiid 

 most distinct, these spots extend as interrupted lines to the dorsal margin, beyond 

 these spots are a number of ill-defined costal spots, becoming a little more distinct 

 towards the apex where they extend as dark lines into the paler cilia ; immed- 

 iately before the middle of the dorsal margin is a conspicuous inverted triangular 

 spot resting with its apex on the margin, obliquely above it and nearer the base is 

 another spot; besides these are smaller, mostly transverse spots, especially in the 

 apical part of the wing; the. larger spots on the disk and dorsal margin are more 

 or less distinctly margined with yellow scales. Dorsal cilia grayish fuscous, 

 barred with darker lines. Hindwings fuscous brown, with a faint, purple lustre. 

 Underside of wings fuscous brown. Abdomen above dark ochreous fuscous, 

 underside of body and legs grayish, tinted with fuscous. 



Exp. 13 0-15.5 mm.; 0.52-0.58 inch. 



Hub. — Pennsylvania (Hazleton) ; Maryland (Plummers Island). 



The specimen which has served as the type for the above de- 

 scription has been taken by me at electric light. Two specimens 

 received from M. A. Busck and taken at the last-mentioned locality, 

 differ from the type in being darker, wing markings less distinct and 

 the yellow scales margining the large spots very sparsely present. 

 It gives me pleasure to dedicate this species to Dr. Dyar. 



A. margoriellsi n. sp. — PI. Ill, fig. 5. — First joint of labial palpi entirely 

 and the second externally fuscous brown, the latter within, the brush anteriorly 

 and the third joint pale ochreous, the latter with an indistinct fuscous dot in the 

 middle of underside. Head ochreous, intermixed with brown. Antennae ochre- 

 ous brown, paler at base. Thorax ochreous, speckled with and patagia anteriorly, 

 fuscous. Forewings moderately wide, arched from the costa and again towards 

 the apex, latter obtusely rounded ; sordid ochreous, as grayish white, irrorated 

 and conspicuously spotted with dark brown, four spots on the costa. the first near 

 the base is oblique, somewhat interrupted and reaches the fold, tin- second spot at 

 less than one-third, a large oval spot beyond the middle and a large subquadrate 

 spot before the apex ; a large spot on the fold at one-half the wing length, a large 

 spot on the dorsal margin near the base; another, less conspicuous, at beginning 

 of dorsal cilia ; besides these are numerous dots and transverse streaks of a paler 

 color, veins dark ; a small, but distinct, spot at end of cell and on costa between 

 third and fourth spot. Cilia pale ochreous, bailed v\ith five or six dark lines, the 

 last costal spots extends into the cilia. Underside pale fuscous, showing some- 

 what the markings of upper side. Hindwings grayish, dusted with fuscous, cilia 

 concolorous. Abdomen above grayish fuscous; underside of body and legs grayish 

 ochreous, dusted with fuscous; anterior tarsi, except joints at apex, dark fuscous. 



Exp. 11.0-16.0 mm.; 0.44-0.64 mm.
