Just what this name stands for can not be ascertained without 

 careful comparison with Walker's type. His description would 

 apply to almost any Anchylopera. As it is, Walsingham, Fernald, 

 Kearfott, and others have agreed upon a certain California form as 

 Walker's species. This appears to be quite variable, as many speci- 

 mens have the palpi fuscous, while others from the same localities have 

 them nearly pure white. We have also in the National Collection 

 a series of moths from the Shasta region which, while not distinguish- 

 able on external characters from the supposedly typical disaigercDna, 

 exhibit so reduced a cucuUus that they appear to represent a distinct 

 species. I believe they are only a local race, but hesitate to describe 

 them under any designation until the identity of the true discigerena 

 is established. Pending further information I am determining the 

 form with white palpi as typical. Like subaequana, maritinia., and 

 anguUfascia7ia, discigerana lacks the uncus. A. lamiana Clemens is 

 referred to the synonomy on suspicion. The type is lost; but the 

 description seems to fit.
