Phoridae. 



or blackish brown, third joint large, elongated; arista very short- 

 pubescent. Palpi black or brownish, with ordinary bristles. Thorax 

 black, dullish, a little greyish, with black pubescence and two pairs 

 of dorsocentral bristles. Scutellum with four bristles, the anterior 

 a little smaller than the posterior. Pleiira black, dull, only a little 

 shining below; they are bare. Abdomen greyish black, in certain lights 

 rather grey, dull, second and sixth segments somewhat elongated; it 

 is clothed with short hairs, forming distinct rows at the hind margins ; 

 at the lateral margins the hairs are longer, and the second segment 

 has here somewhat dense and long hairs; the marginal hairs on sixth 

 segment somewhat long. Hypopygium somewhat large, constructed 

 mainly as in Bergenstammi; the left side with a triangular plate 

 between it and sixth segment, the right side with a somewhat claw- 

 like piece below the hind margin; below there is a ventral plate 

 similar to that in Bergenstammi; anal tube quite short, black. Legs 

 with the femora black or blackish brown, tibiæ and tarsi paler, dark 

 or lighter brownish ; front tibiæ with a dorsal bristle above the middle, 

 middle tibiæ with a pair at about the upper fourth and one anterior 

 near the lower third; hind tibiæ with four bristles, two dorsal, the one 

 at about the upper third the other near apex, further an anterior 

 near apex and an anteroventral above the middle; middle tibiæ with 

 two, hind tibiæ with three apical spurs of various length. Wings 

 light brownish, veins brown, below the fork there is a more or less 

 roundish, generally rather distinct, blackish spot; costa reaching 

 beyond the middle, 1 about equal to 2+3; costal ciHa short, but 

 not specially short; fourth vein curved at the base. Halteres yellow. 

 Female. Similar; antennæ and palpi paler, reddish to yellowish 

 red, and antennæ smaller with the arista longer and more distinctly 



pubescent. Seventh abdominal seg- 

 ment deeply incised above, long 

 haired. Tarsi showing a similar sexual 

 difference as in Bergenstammi, and to 

 a still higher degree, the tarsi stouter 

 and more haired, especially the last 

 joint, claws, empodium and pulvilli 

 large and the hair above, between 

 the claws very flattened and band- 

 shaped; this development is the most 

 pronounced on the anterior tarsi, but still distinctly present also 

 on the hind tarsi.
