and the lines on the primaries are invariably more clouded and 

 confused. The ? is also much smaller than that of O. vetusta, 

 and is brownish instead of smoky gray. I have frequently kept 

 the larvae of both forms, and have found that O. vetusta would 

 not feed upon the oak, and O. gulosa would invariably refuse the 

 lupins. All the species of the genus are ravenous eaters. This 

 is probably a case in which two distinct species approach each 

 other very closely in the imago condition.

Allied to O. leucostigma, Sm. Abb. but differing from that 

 species, by the absence of the white spot on the inner angle, and 

 by the heavier and less oblique transverse lines on the primaries. 

 The secondaries are also of a chestnut tint, and not concolorous 

 as in O. Iciicostigma.

A careful comparison of the examples of this sp. in my col- 

 lection, leads me to the conclusion that it is the same as O. an- 

 tigua, L. of Europe and it is more than possible that O. nova. 

 Fitch, belongs to the same species.
