Ricania afßnis Kirby, Proc. Zool. See, pag. 554 (li 



Very similar to the R. ßavicostalis Kirby, but darker above, the brown bands on 

 the clvpeus beyond the inner carinae darker; under surface of body yellow, with 

 irregulär black markings beneath the wings, and a large spot on the pectus between the 

 first two pairs of legs, abdomen not banded with green above, but with a row of yellow 

 Spots on the sides. Wings hyaline, not tinged with yellow on the costa or inner margin, 

 but with a yellow spot on the costa (likewise edged with black within) before the black 

 Stigma; below the Stigma are some small brown blotches along the line of the inner row 

 of transverse cells; there are also two small brown spots nearer the base on the lower 

 half of the wing; bind margin brown for about one sixth of the width of the wing, and 

 marked with two irregulär hyalin spaces, each covering several cells; close to the bind 

 margin runs an interrupted row of small hyaline dots. Hind wings hyaline, edged with 

 brown, except towards the anal angle. Neuration nearly as in the R.flavicostalis Kirby, 

 but the outer row of transverse cells less numerous. 



Long corp. 9 lines, exp. al. 22 lines.
