Hypena ereotalis, Guence. — % 9- — Bright blackish brown with ashen 

 shade and raised scales in lines and dots. Discal and submedian black longi- 

 tudinal lines or dashes more or less evident. Extra discal angulate line of 

 dark raised scales, followed by a pale shade, distinct and continued. Sub- 

 terminal dentate line followed by pale coincident shade evident on the dark 

 terminal ground color of the wing which is neatly limited superiorly by the 

 oblique apical shade. A continued dark terminal line preceded by pale diffuse 

 terminal points. Hind wings very dark fuscous. Expanse, 30 to 32 m. m. 



Habitat. — Throughout the Atlantic District. 



A well marked form of this species is : 

 a. Hypena subrufalis. 



In both sexes a ferruginous shade fills in the lower half of the wing 

 to the extra-discal or transverse posterior line and renders the dentate 

 transverse anterior line apparent interiorly. It tinges both lines and 

 the terminal space, leaving the costo-apical region ashen as in the 

 type. The discal and submedian dashes are obsolete. The superior 

 portion of the primaries above the ferruginous shade is of a dull sooty 

 black. Else it agrees well with type and occurs as commonly. 



Hypena seabra, Fabricius, sp. — % $. — Larger than H. erectalis, with 

 very wide secondaries. Uniformly darker, more obscurely colored. Eaised 

 scales in dots and lines as in the preceding species. The primaries have an 

 .even somewhat olivaceous blackish appearance, with a slight ashen wash sub- 

 terminally and apically. Expanse, 32 to 34 m. m. 



Habitat. — Very common throughout the Atlantic District. 



Hypena baltimoralis, Guence.— % 9.— This is the American repre- 

 sentative of the European H. crassalis. The primaries are rich brown from 

 the base to the t. p. line leaving the internal margin usually pale. The brown 

 color is produced downwardly near the t. p. line. The line is uneven, pro- 

 jected opposite the disc, thence running inwardly, instead of being continued 

 perpendicularly for a space as in H. crassalis. Beneath the subterminal line 

 is indicated by a single whitish dot below costa where in H. crassalis are 

 usually two. H. baltimoralis varies much in depth of color, and while in 

 some specimens the brown basal patch contrasts forcibly, in others the ter- 

 minal space is nearly equally dark colored. The brown color varies in tint. 

 These darker specimens seem to be analogous to the var. terricollalis of the 

 European H. crassalis. Expanse, 32 to 34 m. m. 



Habitat. — Canada, Eastern and Middle States ; quite common. 

 The male has been described by Mr. Walker, under the name of 

 benignalis. 



Hypena abalienalis, Walker. — % 9 • — Quite nearly resembles the 

 dark var. of H. baltimoralis. The primaries are entirely blackish to the 

 whitish geminate continued t. p. line. This is roundedly outwardly projected
