The 6". decision of Hagen is also probably only another variety. 

 Needham (Aquatic Insects in the Adirondacks, N. Y. State 

 Mus. , Bui. 47, September, '01, p. 521), has remarked in regard 

 to assim ilatum, rubicundulum and obtrusum that "they inter- 

 grade completely." Decision has been recognized as a syn- 

 onym of obtrusion by Calvert. Pallipes has the size and form 

 of assimilatum, the genital hamulesof the male are almost indis- 

 tinguishable from those of obtrusum, while the vulvar lamina of

the female resembles that of rubicundulum most closely, only in 

 some cases it is a trifle more inflated. While combining the 

 structural characters of these three forms, pallipes differs from 

 all of them somewhat in coloration. Perhaps it would be better 

 to list these as separate species until some one with abundant 

 material and the types at hand has threshed the matter over 

 thoroughly, especially as there is usually no difficulty in dis- 

 tinguishing them.
