Genus 10. GYNANISA. 



Antennae thorace longiores. Thorax utrinque fasciculatus. 

 Alae longiusculae, mediocriter lata?, macula minima vitrea ; alae an- 

 ticae non falcatae, apud costam subrectac, apice vix angulatae, mar- 

 gine exteriore obliquo subinciso, macula vitrea angusta ; posticae 

 margine exteriore subinciso, macula vitrea irregulari. Mas. — An-

Saturnia, p., Westiv, ; King. 



Antennae longer than the thorax. Thorax with a lappet on 

 each side. Abdomen not extending so far as the hind wings. 

 Wings rather long, moderately broad ; each with a very small 

 vitreous spot. Fore wings nearly straight in front, not falcate and 

 hardly angular at the tips, oblique and very slightly notched along 

 the exterior border ; vitreous spot narrow, oblique, a little larger 

 than that of the hind wings. Hind wings slightly notched along 

 the exterior border ; vitreous spot irregular in form, enclosed in a 

 very large ocellus. Male. — Antennae very deeply pectinated ; 

 branches of equal length. Abdomen rather stout, extending to 

 about two-thirds of the breadth of the hind wings. Fore wings with 

 the exterior border a little more oblique than that of the female. 

 Female. — Abdomen thick, extending to three-fourths of the breadth 

 of the hind wings. 



This genus may be distinguished from Samia by its vitreous 

 spots, and from the other genera by the form of the wings.
