Pseudopogonota, gen. n. 



Generic Characters. Similar in general habitus to Pogonota zetterstedt, 

 but without the extra cross- veins in the male and with the palpi spoon-shaped 

 in both sexes. First wing-vein bare; sixth vein complete. Hypopygial 

 forceps bearded ; second tergite elongated, very conspicuously so in male. 



Genotype, the following species. 



Pseudopogonota aldrichi, sp. n. 



Male. Grayish black, shining, conspicuously but not densely pruines- 

 cent. Head largely black, center of interfrontalia red, its anterior fourth, 

 the face, and nearly all of cheek sooty black; second antennal joint and base 

 of third reddish yellow; palpi pale basally. Thorax not distinctly vittate. 

 Abdomen unmarked; hypopygium reddish testaceous, inferior forceps glossy 

 black, with a dense fringe of long, golden, bristly hairs. Legs yellowish tes- 

 taceous, coxae and femora more or less infuscated. Wings yellowish, veins 

 pale, cross- veins infuscated. Calyptrae and halteres yellow. 



Head less than twice as broad as high. Orbits narrow, each about one- 

 seventh as wide as interfrontalia, bristles as in the preceding species, almost 

 bare except for the bristles; face receding below; parafacial narrow; cheek 

 over one-third of the eye-height, with a few hairlike bristles on posterior 

 halt and some very short hairs along lower margin; vibrissal angle separated 

 by a depressed lire from cheek, with about six bristles; proboscis slender; 

 palpi spoon-shaped, with numerous short black bristles; arista with its long- 

 est hairs as long as width of third antennal joint. Thorax with presutural 

 acrostichals short, 4-rowed; dorsal bristles distinct, but not long; stigmatal 

 and propleural bristles weak or absent. Abdomen slender, without brist'es; 

 hypopygium rather large, inferior forceps over twice as long as wide, rounded 

 at apices, their outer or ventral surfaces bare, armed along their lower or inner 

 margin with long, densely packed bristly hairs, the surface which is mesally 

 directed with dense woolly hairs; fifth sternite with two short wartlike sub- 

 median protuberances, laterad of which there is a tuft of long black bristles. 



Legs slender; femora without bristles; armature of tibia almost as in pre- 

 ceding species, but the surface hairs much longer. Third and fourth veins 

 subparallel apically. 



Female. Differs from the male in having the head with the exception 

 of upper half of occiput, apical two-thirds of third antennal joint, and pro- 

 boscis reddish testaceous; thorax and abdomen largely reddish testaceous,, 

 infuscated above. Legs entirely pale.
