ALDRICH.- NEW GENERA AND SPECIES OF DOLlCHOPODID/l'.. 157 



Dolichopus duplicatus, Aldrich. 



Kansas University Qitarterly, Jul}-, 1S9B, p. 18 

 Nine males, five females, Moscow, Idaho, at edge of water in Sep- 

 tember. The females are not distinguishable, except by a slightly 

 larger size, from those of tenuipes Aid. The male lamellae, which I 

 could not well make out in the type, are very peculiar. The apical 

 lobe is incised all along its outer border so as to have a sort of fringe 

 of a dozen or more narrow divisions, upon the tips of which are deli- 

 cate hairs. The strong curved bristles are entirely absent. 



Dolichopus ratnifer, Loew. 



One male, Moscow, Idaho, September.
