38 AMERICAN LEPIDOPTERA. 



Six males and one female in the Nat, Mus. Coll., collected 

 by Mr, Augst Busck, and to whom it gives me pleasure to 

 dedicate this very interesting addition to our fauna. 



The above description as far as coloration of wings con- 

 cerns was taken from a male. The female, which appears to 

 be somewhat rubbed, presents an almost altogether different 

 appearance, with scarcerly a trace of ferruginous coloring ; a 

 suffused grayish-fuscous, a trifle darker along both margins 

 and apical portion ; a fine more or less interrupted black line 

 in the fold, edged above by whitish scales, some short, black- 

 ish lines in basal third near each margin ; no evidence of a 

 fascia, the discal spots of the male are replaced by some ir- 

 regular blackish dots ; spots at end of cell distinct, Hind- 

 wings darker, with very little lustre. Both wings are rela- 

 tively wider than in the male, it expands 20.0 mm. 



The coloration and pattern of marking of the forewing in 

 the c? d 1 . appears to be variable in intensity and extent. Vein 

 3 + 4 of hindwing connate or very short stemmed, in one 

 wing at least, separate ; vein 5 free in all. 



13. H. sciaphilella Zell. 



Dr. Zeller describes this species as follows : 

 " Alis ant cinereis, area basali postice abrupta macsulaque costse 

 triangula interins albido — marginata nigricantibus, pari punctorum 

 supra angulum internum nigra, cf." 



" Head and thorax gray, somewhat shining. Antennae gray, excised 

 above the basal joint, excision with obliquely truncated scale tuft. 

 Palpi as long as the thorax, slender, ascending, the second joint closely 

 scaled, grayish-fuscous, white at the apex, terminal joint half the 

 length of the second, pale at apex. Thorax beneath white. Legs 

 fuscous, apices of tibiae and tarsi whitish ; posterior tibiae compressed, 

 both edges with fuscous hairs, apices and a white oblique spot about 

 the middle externally, white, spines white. Abdomen short, gray, anal 

 bush whitish. Forewings three and one-half lines long, rather narrow, 

 of about equal width to tornus. Ground color pale gray, thinly dusted 

 with blackish scales, basal fifth blackish, terminating in a straight, 

 though not sharply defined line, before the middle is a large triangular 

 costal spot, sharply defined and edged with white towards the base, 

 attaining the fold, ill-defined externally, opposite to this is an ill-defined 

 dorsal spot, forming thus an angulated though interrupted fascia, the 

 angle resting upon the fold and the fascia becoming narrower towards
