 frontal hairs; antennae fuscous above, cretaceous below; club red-brown 

 beneath and at the tip. 



The female is very much like the male; some individuals have a small 

 ocellus on the upper median interspace. 



A late form is a little larger, than the other, paler colored, especially 

 beneath, where the inscriptions are faint and the space which on the 

 upper side is occupied by the buff band is scarcely outlined; the mesial 

 band but a shade darker than the basal area.

 cuts made.

 pressed whitish process; color reddish buff, the sides pale green; mid- 

 dorsal stripe pale black; feet and legs gray-green. The chrysalis is 

 about a half inch in length, cylindrical; color red-brown, darkest an- 

 teriorly, the divisions of the abdomen green ; wing cases green, around the 

 margin brown. Pupation takes place under the ground.
