CroesiaT Virginiana n. s. — Female' P^'ore wings bright shining yellow. The 

 Y-like mark that arises from a small patch on the middle of the inner margin, 

 is sanguineous; the branch nearest the base of the wing is entire, rather broad 

 and reaches the costa at the basal third: the branch towards the hinder mar- 

 gin is interrupted at the post-apical vein and on the costa above it is an iso- 

 lated, nearly round sanguineous spot. Between the exterior branch of the Y- 

 like mark and the hinder margin, are free reticulations of the same hue, the 

 transverse markings of which are broad and one of these beneath the tip of 

 the wing forms a spot. Similar reticulations, although not so heavy, exist be- 

 tween the branches of the Y-like mark. Towards the base of the wing, the 

 reticulations are fainter. Hind wings dark fuscous. 



Male? Fore wings rather pale yellow. The Y-like mark is of a brownish- 

 red hue. The exterior branch is less distinctly interrupted and is connected 

 with the costal spot by a slender line, and at the point opposite the costal spot, 

 it is bent towards the hinder margin beneath the tip, where it forms a small 

 roundish spot. The wing is less reticulated than in the female. Hind wings 

 blackish-brown. 



Length of fore wing 9 ^ lines; % 3 lines.

Croesia? gallivorana n. s. — Fore wings of a rich, deep straw color, reticu- 

 lated with reddish-orange. The Y-like mark is replaced by a purplish-red 

 patch near the middle of the inner margin, slightly produced towards the apex 

 of the wing, a spot of the same hue on the basal third of the costa. and a small 

 one of the same hue near the tip of the wing, extended along the hinder mar- 

 gin, and witli which the patch on the inner margin is more or less connected 

 by its short exterior branch. Cilia yellowish. Hind wings whitish, tinted with 

 fuscous. Thorax yellow, with a reddish-orange stripe on each side. Patagi.i 

 yellow, touched in front with reddish-orange. Antennse fuscous, reddish-
