the forewings is uniform, though more pronounced in costal 

 portion of the wing; a slightly paler shade, especially before 

 the first discal and surrounding the spots at end of cell is 

 noticeable in some specimens. The first discal spot before 

 the middle, and the two spots at the end of cell, are quite 

 distinct in the type and all specimens before me. Hind- 

 wings nearly 1, with considerable lustre, cilia under 1, paler 

 than the wing. Abdomen fuscous, paler beneath ; anal bush 

 ochreous. Legs fuscous, especially anterior and median ; 

 hind tibia dark gray with median band externally and at apex, 

 paler ; rough haired above ; tarsal joints paler at apex. Ex- 

 pansion 17.0-18.5, 0.68-0.94 inch. 



Hab. — Penna., Maryland (Plummer's Island). Occurs un- 

 doubtedly over whole Atlantic district. 



Might be confounded with H. dives, but differs, by its 

 smaller size, relatively broader forewings, well marked dis- 

 cal spots, paler coloring and less lustre, and above all by the 

 less profound excision and much shorter cilia of the male 

 antennae. Agrees in wing form and antennal structure with 

 chalcofrontella, and resembles somewhat var. fumerella of that 

 species, but lacks the mottling of the latter. 



7. H. ochrocepliala n. sp.— Head, thorax, and palpi pale ochre- 

 yellow ; the latter long, ascending but slightly recurved, terminal joint 

 almost as long as the second, speckled, especially externally, with 

 fuscous scales, leaving the apices of second and terminal joints paler. 

 Basal joint and two or three basal joints of shaft of the antennae yel- 

 lowish-white, very slightly speckled with fuscous, remainder of shaft 

 grayish-fuscous, anterior (exclusive of patagia) and posterior margin 

 of thorax dark purplish- brown. Forewings moderately wide, grayish- 

 fuscous, suffused in patches with dark fuscous, and overlaid with pur- 

 ple, extreme base, excepting its costal margin, pale ochre-yellow ; first 

 discal spot distinct, before the middle and nearer to the costal margin, 

 two spots at end of cell less distinct, coalescent, cilia grayish-fuscous, 

 paler at base. Hindwings 1, grayish-fuscous ; cilia scarcely over \, 

 grayish-fuscous, paler at base ; vein 5 out of stalk 3+4. Abdomen 

 above fuscous, beneath sordid yellowish-white, anal segment deep 

 ochreous. Underside of thorax and legs pale ochre-yellow, speckled 

 more or less densely with fuscous, leaving the ends of tibia? and poste- 

 rior tarsal joints paler. Expansion 16.0 mm., 0.64 inch.
