HABITAT. Hudson's Bay Territory; Adirondack Mountains, New 

 York, in August. 



Types of contacta and diffusilis are iu the British Museum, though" 

 I did not see the contacta. Mr. Grote apparently did see it, and as he 

 had the type of Harvey's species his reference can be taken as correct. 

 The type of aspera is in the Tepper collection, and is the same as diffu- 

 silis type.
