These specimens have the tegmina with the transverse fuscous 

 clouds very distinct proximad, becoming weak distad and extending 

 across the tegmina except for the anal area. The rosy suffusion 

 of the costal section of the wing is weaker than on the disk, being 

 only a coloration of the veins on a fuscous ground. 



Brunner has recorded this species from near Guayaquil, Ecuador.

The size of the female of this species is very considerable and 

 would serve in a great measure to identifj^ it,, aside from the slender 

 form and distinctive coloration. 



This appears to be the first definite record of the species.
