Saturnia Schrank. 



S. g a lb in a. Antennae luteous. Body and head rather dark brown. 

 Fore wings yellowish-brown, with a rather faint whitish, angulated band at 

 the base. On the discal nervure is a round, black ocellus having a central 

 subvitreous streak, containing a yellow circle, and toward the base of the 

 wing a slender blue crescent. A whitish band crosses the middle of the ner- 

 yules, with a faint wavy one between it and the hind margin. In the apical 

 interspace is a black spot, with a crimson streak to the tip of the wing. The 

 marginal portion of the wing is whitish, and is tinged on the terminal edge 

 with pale yellowish brown. Hind wings similar in color and ornamentation 

 to the fore wings, the ocelli being somewhat smaller. On the under surface, 

 which is similar in hue to the upper, the faint wavy bands of the fore and 

 hind wings are very distinct.

Pimela. 



In the fore wings, the costal and subcostal nervures are placed near each 

 other and the exterior margin. The subcostal sends a single marginal branch 

 from near the posterior-superior angle of the disk, delivered to the margin 

 near the tip, and just behind this angle divides into two branches ; the upper 

 one or the apical is simple, and the lower one is subdivided into three ner- 

 vules, the post apical arising near the upper third and the infra post-apical and 

 subcosto-inferior near the middle. The discal nervure arises midway between 

 the origin of the subcosto-marginal branch and that of the apical ; it is acutely
