160 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 90 



Type locality. — Cincinnati, Ohio. 



Food 'plant. — Unknown, 



Remarks. — Described from $ type and 5 2 paratypes all from the 

 type locality (March and April dates, 1904^1908, Dr. Annette F. 

 Braun). Paratypes in the Canadian National and Dr. A. F. Braun 

 collections. 



This species is much like inegamicreXla but is lighter in color, lacks 

 the fuscous or brown suffusion, and is more contrastingly and more 

 sparsely marked than that species. In male genitalia it differs from 

 megamwreTl<i in the stouter expansion and the angulate outer dorsal 

 margin of the sacculus. In the female the ostium is smaller as is 

 the posterior dilated portion of the ductus bursae adjacent to it. 

 The posterior loop of the ductus bursae is less strongly sclerotized. 



This is the species placed under megamicreUa by Forbes. 



I take pleasure in naming this species after Dr. Annette F. Braun, 

 who collected the type series.
