AMERICAN LEPTDOrTERA. 193 



two whitish coalesced spots, obsoletely separated by the 4th ui. nev- 

 viile. The exterior portion of the wing is frosted with pale scales. 

 Secondaries black, with a narrow white exterior well defined band 

 running over the nervules. Under surface resembling upper. 



% resembles 9 . Anal abdominal hairs red. Primaries rusty black, 

 closely scaled. A well defined broad discal mark, beyond which, and 

 nearer to costa, a similar but larger lunated spot. Two coalesced spots 

 obsoletely separated by the 4th m. nervule. Terminally the wing is 

 frosted with pale scales. Secondaries black, with a single narrow sub- 

 obsolete subterminal whitish band, forming a spot opposite the discal 

 cell. Underneath as above; the band on secondaries broader and more 

 distinct than on the upper surface.

This more slender species is at once distinguished from II. maia, by 

 the densely scaled wings, the short broad discal lunate spot of prima- 

 ries not surrounded by deeper black scales, and by the entire absence 

 of an analogous spot on the secondaries in either sex. The narrow 

 well defined bands are whiter than in H. maia. The elongate spot 

 over the 4th m. nervule on the primaries does not reach. the internal 

 margin, while in H. maia, the band at this place attains the margin 

 and spreads along it. In H. grotei this band is represented merely by 

 a superior and inferior maculation. Under the glass the discal spot 

 on the upper surface of 9 primaries is seen to be deprived of scales. 



The Berlin Museum possesses a number of specimens of Plem. 

 maia, taken in Texas by the same Collector, and which do not differ 

 from our Northern individuals of this species, except in their som.e- 

 what greater expanse. 



HYPERCHIRIA, Hiibner. 

 Hyperchiria zelleri, n. s. (Plate 2, fig.* 65 9 •) 



9 . — Size large, form stout. Head and palpi rich dark brown; anten- 

 nae testaceous, a little slenderer than in allied species. Thoracic re- 

 gion, above, dark brown ; lateraly, at the insertion of the primaries, are 

 arranged short whitish hair-like scales which form a spreading tuft. 

 Abdomen, above, bright ochreous brown ; beneath with under thoracic 

 surface and legs, of a rich brown, a little paler than upper thoracic 

 surface and head. 



Wings full and large. Primaries arcuate along the costa ; apices
