Head, body, and palpi as in Sicya .Male antennae more heavily pec- 

 tinated than in Sicya; in the female simple. Fore wings triangular, the Costa 

 straight; apex subrectangular, the outer edge long, oblique, without any 

 angle in the outer edge. Hind wings large and full; outer edge full and 

 rounded, with a slight sinus just before the middle of the outer edge; they 

 reach a little beyond (he end of the abdomen. Venation: costal vein anas- 

 tomosing with the subcostal. Six subcostal venules, the first very short, one- 

 halt' as long as the second, and co- originating with the first from a common 

 branch; the third and fourth originating from a commoq branch; no sub- 

 costal cell. The independent vein is situated rather nearer the sixth subcostal 

 vein than usual; the anterior discal venule being short, while the posterior 

 one is oblique, but not much curved. .Male hind legs much as in Sicya; the 

 tibiae are very slightly swollen : the tarsi about one-fourth shorter than the 

 tibi;e. Coloration: straw-yellow, with no markings except threecostal spots, 

 the middle one ol which connects with a \r\-y large oval discal spot. 



This genus differs from Sicya, Antepione, and Heterolocha in the tore wings 

 being entire, not falcate, the outer edge regularlj convex, not excavated, and 

 the liiinl wings rounded, not angular on the outer edge, and u living a faint 

 sinus below the apex. It is more closely allied to Angetona than any 

 other American genus of this subfamily, being like that genus in the entire 

 lore wings and in the sinus in the hind wings. The fore wings are a little 

 pointed at the apex, and less angulated in the middle of the outer edge. The 

 subcostal venules are shorter, sent more directly to the COSta, and the costal 

 interspace narrower. Hind legs as in Angetona, the spurs of the same relative 

 size. The female is smaller than the male, while in Angerona the female 

 is considerably larger than the male. Ai first regarding our species as generic
