AMERICAN LEPIDOPTERA. 265 



subobsolete basal lines : an even, broad, black line reaching from costa outward 

 nearly to discal spot, then turning back at an angle a little more acute than a 

 right angle, straight to inner margin ; a faint line bending just beyond and 

 around discal spot; an outer well-marked black line; outer space broken, dark 

 fuscous; hind wings with black band of fore wings extended close to base across 

 the wing meeting the black second segment of abdomen ; outer lines also present 

 to correspond with fore wings; all discal spots and marginal lines distinct bla(!k ; 

 beneath more fuscous, the middle band absent, the outer lines showing. 



Blanco County, Texas, October. 



G. ininuta n. sp. — Expands 15-17 mm. Palpi rather short, quite stout, 

 dark gray; front blackish or dark gray above and below, white in middle; 

 thorax and abdomen light gray, the latter blackish gray on second segment; fore 

 wings rather extended, light gray or whitish, darkened with bhiish or dark fus- 

 cous scales showing especially on outer middle and marginal spaces forming 

 between them a light cross-line, often indistinct, forming nearly a right angle 

 beyond discal spot and running thence straight to inner margin ; marginal line 

 fine, black ; discal spot black, distinct; hind wings whitish, cross-lines very faintly 

 indicated a little darker along inner margin : marginal line black ; discal spots 

 not very distinct; beneath light cinereous, slightly shaded with darker color.

Type pimllata Fab.

 Eiipithecia Curt., Brit. Ent. ii, 64, 1825, type linariata Fab. 



Palpi short to long, slender to heavy, porrect or drooping ; front 

 not strongly tufted ; antennte filiform, ciliate in both sexes ; thorax 

 untufted. Abdomen with tuft on each segment dorsally ; fore tibiae 

 unarmed, hind tibije with all spurs; fore wings 12 veins, two acces- 

 sory cells ; hind wings 8 with cell to beyond middle, (i and 7 separate 

 or stemmed. 



A large genus as defined, consisting mostly of small species. The 

 species so gradually merge into one another in structure, and are so 

 largely midway between the extremes that I have not attem})ted any 

 closer limitations, and so do not give a more exact generic diagnosis.
