Philopotamus americanus Banks, 1895, p. 316. 
Lectotype, male. — New York. No. 11512. 
Both Banks and Betten have given illustrations showing 
a difference between this species and distinctus Walker. 
While these differences do occur, I have found all inter- 
gradations between them in a study of specimens from 
Michigan, New York, North Carolina and Maryland. All 
collections which I have seen containing specimens of both 
sexes are alike in having the females with minute, vestigial 
wings. This evidence indicates that only one species is 
involved in this material.

its exact placement cannot be given.
