easily to be seen that there are very insufficient if any grounds for 

 the sinking of Grote's name, or for making this, his species, a 

 var. of Harris', as any one will see by comparing a suite of the two 

 that they are very different in size and color and in markings, as 

 much as is the case with species of the same group in this interesting 

 family. I have received argenteomacu/atus from Maine, Canada, New 

 York, Michigan, Illinois and Wisconsin. Quadriguttatus only from 

 White Mts. of New Hampshire and Maine. In the last named State 

 the two occur at same time and in same localities.

Unknown probably save from the type and description. I have 

 never seen the former, but from the description it must be a large 

 species (" expands 4'20 inches ") unique in appearance it being des- 

 cribed as " dark sable brown with irregular bands of silvery purple. 

 Head and body deep sable brown ", etc. It was " captured by 

 Mr. S. H. Scudder at the base of Mt. Washington " and is a 9 .

A large white species with but little of the usual ornamentation on 

 primaries and that little confined mostly to inner half of costal part. 

 The type was taken in a park in Montreal by the late Mr. F. B. 

 Caulfield of that city from whom I received it. Another was 

 taken later, I think near the same city, and a third one was captured 

 in Wisconsin. The remaining species of North American Hepialidse 

 of small size and, excepting auratus Grote, are inconspicuous insects 

 presenting little affinity in appearance to those here enumerated.
