FiGURE 124. — Localities for Ageniella blaisdelU. 



Female: Forewing 5.0 to 8.5 mm. long; apical hairless margin of 

 clypeus widened medially into a weak tooth; clypeus weakly impressed 

 sublaterally so that the central half of its apical margin is not dis- 

 tinctly set off from its lateral quarters; frons almost mat with fine, 

 very close punctures. 



Ferruginous. Hind wing faintly tinged with brown, a little darker 

 apically; forewing brown, a little paler basally and a little darker 

 over the basal vein and nervulus and with a crescent-shaped faintly 

 paler subapical area. The forewing thus has a suggestion of the 

 banded color pattern characteristic of A. conjiicta and A. accepia, 

 but its general appearance is rather uniformly brown.
