hair-like bristles ; ninth segment evenly rounded, uniformly colored 

 throughout, same as remainder of segments, except a clear portion 

 on each side of posterior margin, from which arise two long hairs, all 

 the segments from first to seventh furnished with a row of fine hairs 

 along the posterior border, about twenty in number ; eighth segment 

 with but two on each side of middle. 



Legs rather long and strong, front femora much swollen, hind fe- 

 mora slender, all legs having a few short stiff hairs on the femora 

 and tibiae. 



Taken on Rip aria riparia. This form is nearest N. pulicaris 

 Nit. and N. bruneri Carriker, resembling most in coloration 

 the latter form, but from which it may be distinguished at a 

 glance by the broad, very flatly rounded forehead. The female 

 is larger, especially the abdomen, measuring about 1.60 mm., 

 with an abdominal width of .62 mm.
