in the type of rujula and in the specimen from Ecuador; wrinkling as 

 transverse parallel ridges in the specimen from Panama; and ^vl'inkling 

 as a faint, fine, irregular reticulation in the specimen from Texas. 

 These three types of wTinkling suggest that there are tliree species

Fulvous. Prosternum and median areas on mesosternum and 

 metasternum fuscous; wings lightly suffused with yellowish brown, 

 the forewing with narrow transverse brown bands along the basal 

 vein and nervulus, just beyond the stigma, and at the apex. These

The name tabascoensis is applied according to Cameron's original

 Yarrow. More specimens may show that more than one species is 

 included here.

Subfamily Ceropalinae 



Probably the sharply'' compressed subgenital plate of the female is 

 the most distinctive recognition mark of the subfamily Ceropalinae, 

 the characters of which are summarized in the key. Most of these
