We have a single specimen of hexadactyla kindly supplied by 

 Mr. Busck from the Hofmann collection in the National Museum. 

 This specimen is much lighter and more ochreous in general appear- 

 ance than our large series of the North American species, and entirely 

 lacks pure white scales. It is otherwise closely related. The genitalia 

 show enough differences, we believe, to warrant the retention of 

 moniana as a good species, though they are of the same general form 

 The gnathos is more spatulate in hexadactyla, the uncus in our one 

 slide appears to be notched, but without the two small processes which 

 are found in montana, and the basal processes on the claspers are much 

 more blunt. 



Under the name hexadactyla Dr. Dyar published a few notes 

 (Proc. U. S. N. M. XXVII. 924) which indicate that the larva prob- 

 ably mines the leaves of snowberry (Syniphoricarpos spp.). The Euro- 

 pean hexadactyla lives in the flowers of honeysuckle {Loniccra).
