HABITAT. Hudson's Bay Territory; Canada; California. 



This species is omitted from Mr. Grote's list of 1891, and from my 

 own as well. I believed that the northern type was psewloyarnma and 

 the western, calif arnica. I am not certain now that such is not the 

 case: but as I have not had an opportunity of comparing' types I give 

 the species a place pending further study.

Guenee's type is in the British Museum and the specimens from the 

 Grote collection are like it. Californica Speyer is a slight variety of 

 </M, and not of gamma, as Speyer thought. The California localities for 

 (/tinnna are probably based on this species. Dr. Stivoker states very 

 positively that his California examples are gamma. Mr. Edwards's 

 variety is scarcely worthy a name.

HABITAT. Texas. 



The type is in the British Museum. As already stated, Mr. Grote 

 had correctly identified ou, and Mr. Morrison's reference of Jratdla is, 

 therefore, incorrect.
