ings all antenodal or extending beyond the nodus only pos- 

 terior to the costa eponina. 



2'. Wing membrai-iC hyaline; a colored area distal to the stigma 

 and another midway between stigma and nodus, the two 

 areas varying greatly in size 3- 



3 (2')- Spot between nodus and stigma rounded and not reaching the 

 costa; a smaller spot, sometimes wanting, on the anterior 

 end of the triangle in the front wing extending forward at 

 a maximum to M^ ,, no other antenodal markings in the 

 front wing ; antenodals and postnodals more or less darker 

 edged, especially the basal antenodals of the second 

 series cVisa. 



3'. Spot between nodus and stigma not rounded, reaching the 

 costa broadly and often divided or constricted into an ante- 

 rior and a posterior portion ; a larger or smaller colored 

 area or areas proximal to the nodus in the frong wing, 

 especially between Sc and R, where the colored area may 

 extend from the wing base to the nodus ; antenodals and 

 postnodals not darker edged excepting sometimes the 

 former in areas in which, in other specimens, the entire 

 membrane is dark 4. 



4(3')- Wing markings relatively reduced in area, brown or black in 

 color with paler areas hyaline, antenodal dark area in front 



wing extending posteriorly no farther than Mspl 



nionomelaena. 



4'. Wing markings relatively more extensive in area^ brown or 

 black in color with the enclosed pale basal area in the hind 

 wing and sometimes other antenodal pale areas more or 

 less yellowish or orange tinged; antenodal dark area in front 

 wnng extending posteriorly across Cu^ fasciata. 



5 (i')- Two rows of cells between M, and Cu,, in the front wing at 



about the level of the nodus (Mspl not well developed, sep- 

 arated from M^ and from Cu^ by one row of-cells) 6. 



5'. Three rows of cells between M^ and Cu^^, in the front wing 

 at about the level of the nodus (AIspl well developed, sep- 

 arated from M^ by one row and from Cu^ by two rows 

 of cells) 7. 



6 (5). A double cell between Cu^^ and Cu„ in the hind wing at their 



origin. Thirteen or more cells between Cu spl (A^) and 

 A, (A3) in the hind wing (any double cell counted as one). 

 Three cells in the first row distal to the triangle in the 

 hind wing. Face and frons above pale yellowish or 

 greenish, frons darkening to a reddish yellow in old 

 males ; frons dark at base in a triangular area which sur- 

 rounds the median ocellus with a border about as wide as
