Antei)n;e doubly bipectinated, the upper branch the shorter ; of O serrate. 



Primaries : N'eiii 1 free ; median vein three branched, cell closed, 5 from 

 below ape.x of cell, 6-8 on a stalk from apex of cell ; 9-10 absent ; 11 from sub- 

 costal vein on the cell ; 12 from base of wing. Secondaries : One internal vein, 

 median three branched, cell closed, 5 from cross vein very near apex of cell, 6-7 on 

 a stalk from apex of cell, S from base of wing, arcuate, remote from subcostal vein. 



This genus is related to Or/iiiscoJcs, Blanch, but differs in 

 detail of venation. 



In Or/niscodcs ciniiaiiioDica^ the type of the genus, vein 7 of 

 primaries arises from a stalk ; otherwise the venation is practically 

 the same. 



The following is the syncMiymy of the North American species.

Mr. Neumoegen has a c5 specimen from Chili, and we have 

 examined a V specimen belonging to Mr. J. Doll, also from Chjii. 

 The latter has been kindly loaned to us by Mr. Doll and carefully 

 (•omi)ared with the typical specimen in the Edwards collection, 

 now in the American Museum of Natural History.

A form in which the ordinary buff shades of the fore wings 

 are turned to retl. The color is marked, and comes out most dis- 

 tinctly in the cell ne.xt to the white dots where it is "orpiment 

 orange" (Ridg. pi. \ 1. fig. i) or a very little duller in shade. The 

 lines are reddish-brown, the dots laige, white, roinuled ; the apical 

 space grav, exactiv as in i,'//'/vMv/, not red shaded, but contrasting
