yellow al the hind angle aud margin. The species varies in the distinctness 

 of the lines and discal spots. 



VVithoul suspecting at the time of describing the Pacific-coasl and 



eastern specimens that they belonged to the same species, I did not bring 



.them together, but on careful comparison I see no reason for separating 



them. The Californian specimens (length of fore wing, S, 0.72 inch) are 



a little larger than the Maine examples (length of fore wing, 0.66 inch).

Male, an ten use plumose, the pectinations being much longer than in 

 Sicya; in the female, well pectinated, about one-third shorter than in the 

 male. Head a little wider and fuller than in Sicya. Palpi as in Sicya. 

 Fore wings sublalcate, much as in Sicya, but slightly less excavated below 

 the apex, especially in the female. Hind wings much as in Sicya. but rather 

 fuller and rounder, less angulated. Venation: but one subcostal cell ; discal 

 venules much less oblique, otherwise as in Sicya. Hind legs as in Sicya, 

 the tibiae not being swollen, and the tarsi long and stout. Coloration: yellow, 

 with a scalloped outer line, the edge of the wing beyond brown ; but in the, 

 hind wings the outer margin is not discolored. 



Sicya being the better known form, I have made that genus the standard 

 of comparison with this. In the form of the body and the shape of the 

 wings, 1 lie two genera are closely alike; the chief difference between them 

 being that the female antenna' are well pectinated in Heterolocha, but in 

 Sicya they are simple, while the fore wings area little less excavated and the 

 hind wings less angular in Heterolocha, the differences being most apparent 

 in the females.

5 <? and 6 ?. — This very interesting species evidently is an aberrant 

 form of this genus of Lederer's. The head agrees with that of Antepione; 

 the form of the wings is a mean between Opisthograptis and Antepione. The 

 wings seem to be more falcate aud the outer edge mure oblique than in the
