228 THE CANADIAN ENTOMOLOGIST. 



$ . Concolorous, silky drab, veins tending to be paler marked. 

 Primaries with diffuse darker terminal shading, and a discal narrow 

 outwardly extended streak. An exceedingly fine and faint outer transverse 

 line, rounded opposite the discal cell. A subterminal oblique punctiform 

 line from apices to internal margin within the angle. Costal margin dark 

 shaded. The discal dots are perceivable against the longitudinal discal 

 streak. Hind wings a little paler with a very faint transverse shade line. 

 An interrupted fine dotted line before the silky fringes on both wings. 

 Beneath darker ; the hind wings much clouded with dark brownish, with 

 a distinct discal spot and a continued transverse guttiform or cuneiform 

 subterminal line, analagous to the subterminal line of the forewings 

 above ; faint traces of an inner transverse line. Forewings without 

 markings except an incomplete reproduction of the subterminal shaded 

 apices. Body parts concolorous ; abdomen like hind, thorax like fore 

 wings. 



$ . The labial palpi are held as in the $ , but the third article is 

 more pointed. Slighter than the $ , with simple antennae and with 

 almost wholly blackish brown primaries ; the $ exhibits two transverse 

 lines, while both female specimens have entirely glossy brown forewings 

 without apparent marks except the inconspicuous discal points. Hind 

 wings pale drab with faint darker terminal shading. Beneath the second- 

 aries have the double lines more equally defined. Thorax and head dark, 

 concolorous with primaries. 



Expanse, J 21 to 23 m. m. % 21 m. m. Habitat, Philadelphia, one 

 $ ; Texas, one $ , two °. 's. The types are in the collection of the 

 Buffalo Society of Natural Sciences, The Texan male has the primaries 

 darker, more streaked with brownish. This and the slightly smaller size 

 caused me at first to suspect a distinct species in the Texan specimens. 

 The darker greasy tinting of the primaries will probably prove variable in 

 disposition.
