yellow iit (he hind angle and margin. The species varies in (he distinctness 

 of tli(^ lines anil discal spots. 



Without suspecting at the time of describing the Pacilic-coast and 

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

 them together, but on careful comparison I see uo reason tor separating 

 them. The Calitbrnian specimens (length of tore wing, <?, 0.72 inch) are 

 a little larger than the ^Taine examples (length of fore wing, O.GG inch).

Male antennas plumose, the pectinations being much longer than in 

 Sirya: in the female, well pectinated, about one-third shorter than in the 

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

 Fore wings subfalcate, much as in Sict/a, 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: Init one sul)costar cell ; discal 

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

 the tibit¥ not being swollen, aiul the tarsi long and stout. Coloration: yellow, 

 with a scallo^jed outer line, the edge of the wing lieyond brown; but in the 

 hind wings the out^r 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, the two genera are closely alike; the chief difference between them 

 b(!ing that the female antennre are well pectinated in HetcroIoclKi, but in 

 Sicya they are simple, while the tore wings arc a little less excavated and i\u'. 

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

 in the females.
