long as the inner edge of the wing. The hind wings are short, scarcely 

 reaching to the end of the abdomen. Venation somewhat as in Phigalia, 

 but the discal venules are situated in the middle of the wing, and there are 

 six subcostal venules; the first and second subcostal venules are thrown off' 

 from a common branch, and both curve alike toward the costa. In color- 

 ation, the species are much as in those of Biston; but the extradiscal line is 

 distinctly angulated, where it is not bent in Biston. The abdomen is perhaps 

 rather longer than in Biston. 



Larva. — Ramiform, large, and with a notched head. The pupa is sub- 

 terranean. 



There is no good reason why Hiibner's name Eubyja should not be 

 adopted; besides having the priority over 'Treitschke's, it is defined and 

 limited in accordance with the genus as it now stands. 



Synopsis of the Specks. 



A. Wings broad, white as a ground-color : 



The extradiscal Hue very augular, especially on first median venule E. quernaria. 



Like quernaria, but the extradiscal line on the hind wings not bent outward E. cupidaria. 



B. Wings narrow, ash-colored: 



Extradiscal line bent at right angles on the independent, not wavy A. mgnataria.
