all the femora inferiorly, and with outward fringes of long hair on 

 the tibiffi, forming no tufts in either case; but those on the middle 

 pair more prominent than any of the others. In the antenna^ there is 

 a longer bristle on each side of each joint. 



The male genitalia are unique and rather simple. The harpes are 

 somewhat narrow at base and, at a little less than half their length, 

 divide into a broad inferior lobe and a narrow superior continuation, 

 which again enlarges into a broad rounded tip, the inner surface of 

 which is set with short, stiff, pointed spines. The clasper is a small, 

 curved claw or beak at the point where the harpes divide. 



In all the other species there is either no obvious tufting of any 

 kind behind the collar or there is a small divided crest. 



In the group pseudargyria we have two species with robust bodies 

 and comparatively short, obtuse primaries, in which both the ordinary" 

 spots are marked and the transverse posterior line is composed of a 

 double series of venular dots. Both are reddish luteous in color and 

 are more or less black powdered. 



PHe\id(ii'(iyria has the abdomen conspicuously tufted in the male, 

 and the genitalia have dense hair and scale tuftings. The legs in the 

 same sex are very prominently tufted, the most conspicuous clothing- 

 being on the anterior pair. The coxa has a tuft of long, curly scales 

 on the outside. The femui- has a bunch of thick blackish hair inferi- 

 orly, longest toward the tibia, capable of brush-like expansion. The 

 tibia has a dense covering of black hair capable of fan-like expansion 

 exteriorly — altogether a verj- striking modification. The middle leg 

 is rather shorter and stouter than usual; femur with a fringing of long 

 hair inferiorly; tibia set with long hair on all sides so as to form 

 a prominent loose brush, not capable of fan-like expansion. In the 

 posterior leg the femur is fringed with long- hair inferiorly, but not so 

 much as on the others; the tibia with a clothing of thin hair on all 

 sides, not forming an obvious brush. 



The genitalia resemble those of the group commoides. The harpes 

 are very broad at base and narrow only a little inferioi'ly for nearly 

 two-thirds their length, then they are cut off abruptly from below to 

 form a narrow, oblong, obliquely rounded tip. This oblique tip is set 

 with long, rather stout bristles. At the point on the upper margin 

 where the oblong tip joins the broad body of the harpe there is a 

 curved elevated ridge with the margins turned in, forming a crater- 

 like cavity with the outline incomplete. The clasper is a moderatelj" 

 long and stout cylindrical hook, not much curved, arising from the 

 inner portion of the crater over a broad, irregular, corneous plate. 



The species occurs east of the Rocky Mountains throughout the 

 greater portion of the United States and Canada. 



PllqMljjis is obviousl}" related to the preceding in appearance, but 

 has a prominent diffusely margined l)lack shading from the reniform
