174 ENTOMOLOGICAL NEWS. [April, '14 



slightly larger than third joint of antenna, with several end bristles; 

 proboscis thickened and enlarged, almost identical in form with that 

 of Aphiocliaeta rostrata Brues. 



Mesonotum with i pair of dorso-centrals ; scutellum with 2 bristles. 



Abdomen almost bare, anal organs hairy. 



Fore tibia with i dorsal bristle before the middle ; mid tibia with 

 the normal 2 on basal third very weak, and the one at apex not dis- 

 tinguishable ; hind tibia without any bristle, or with a weak one on 

 antero-dorsal surface before middle. 



Costa to about three-fifths the wing length, first division equal to 

 2 plus 3, 3 about three-fourths as long as 2 ; fourth vein leaving third 

 at about midway from fork to apex with a very decided curve (as 

 in Trupheoneura zntrinervis Malloch) and ending almost at wing tip; 

 seventh vein less distinct than the others, but complete ; costal fringe 

 fine and close, its length equal to about twice the diameter of costal 

 vein. Length 1.5 mm. 



Holotype 9, Westville, New Jersey, April ii, 1900. Type 

 No. 6054. 



Paratypes: 6 specimens with same data. 



I consider that this species belongs to the genus in which I 

 have placed it rather than to Trupheoneura with which it has 

 certain affinities. The species in the latter forms have the 

 seventh vein interrupted except in the case of the female of 

 lugiibris Meigen. which has that vein complete, but indistinct. 

 There is a close resemblance between certain species in Tru- 

 pheoneura and others in Psendosfenophora, but so far as I 

 have seen the following set of characters may be relied upon 

 to distinguish the species of the latter forms from all other 

 Phorid genera : Frons much bro^ider than long ; mesonotum 

 with I pair of dorso-centrals ; scutellum with 2 bristles ; male 

 hypopygium large, but without any projecting anal organ 

 and not highly chitinised as in Trupheoneura ; legs with gen- 

 erally the following bristles : i on fore tibia, 2 weak ones at 

 basal third of mid tibia, and occasionally a weak one at apex, 

 and the hind tibia never with more than one bristle ; third 

 vein of wing forked. 



This is the first species of the genus that T have seen from 

 America.
