line white, while the curved apical white line is very distinct, extend- 

 ing from a little above the apex around to just beyond the middle of 

 the costa, where it is continued along the margin to the inner third of 

 the wing. Secondaries a little paler, the apex and outer margin con- 

 colorous with the primaries. 



Beneath a little paler, more glistening, the inner margin of the pri- 

 maries and the secondaries below the costa and within the outer margin 

 paler. 



Length of body, .30 ; cxp. wings, .82 inch. 



Boston, (Mr. Sanborn.) \ 



Cyrtosia fusca n. sp. 



% . Dull white, dusted with ochreous brown scales, thickest at the 

 base of the wing. Head and thorax ochreous brown. Two parallel 

 bands of brown, the outer one approaching the inner, and shortened 

 by a straight line running from near the internal angle to the costa 

 near the inner line. Beyond this line the apex of the wing is nearly 

 white with a few ochreous scales. The wings are darker between the 

 two lines, and especially so upon the costa. 



Secondaries in color pale as the apex of the fore wings. Fringe in- 

 terlined at its base and on the outer edge with dark. Beneath pale, 

 the costal edge of the fore wings dark. 



Length of body, .32; exp. wings, .75 inch. 



Newburg, N. Y., (Coll. Mr. Edwards.) 



Mr. Edwards reared the specimens described above from the larva, 

 and it is hoped that we shall at some time be acquainted with the larval 

 form and habits of a genus of this group hitherto unknown. The co- 

 coon sent with the specimen is short and nearly spherical, about the 

 size of a pea, and of a pale chestnut color. The pupa skin is very thin 

 and fragile, not preserving its form at all after the moth has escaped. 



Cyrtosia geminata n. sp. 



% . Vei-y pale, dusted with ochreous brown, with two white spots 

 near the internal angle. This is the palest species of the genus, its 

 color being an ochreous chalky white. The middle of the fore wings is 

 covered with a large triangular ochreous brown area, excavated deeply 

 upon the internal angle, making a broad inverted V. Just above the 

 internal angle are two unequal rounded triangular white spots, a little
