ART. 10. :N^EW species of the family TIPULIDAE ALEXANDER. 11 



Typc.—Msde, Cat. No. 28089, U.S.N.M. 



Paratypes are in the collection of the U. S. Biological Survey and 

 of the writer. 



It should be noted here that this group of flies will probably be 

 found to be more closely related to Cladura and Crypteria than they 

 are to LimnopMla. European representatives of the group have 

 recently been discovered. 



LIMNOPHELA EUXESTA, new species. 



General coloration polished black, the mesonotal praescutum with 

 three narrow interspaces of yellowish gray pollen; remainder of the 

 mesonotum and pleura with a gray pruinosity; halteres yellow; 

 wings with a faint yellowish tinge; stigma small, brown; r near the 

 tip of R^; R2+3 long; basal deflection of Cu^ a short distance beyond 

 the fork of M; male hypopygium with the pleurites stout, the single 

 pleural appendage slender, chitinized. 



Male. — Length 12 mm.; wing 11.6 mm. 



Female. — Length 14 mm.; wing 11.5 mm. 



Rostrum and palpi black. Antennae black, short in both sexes, 

 the first scapal segment sparsely pollinose. Head shiny black, the 

 front and a band across the vertex connecting the eyes yellowish 

 gray pruinose. Head strongly narrowed behind. 



Mesonotal praescutum shiny black with a triton-shaped yellowish 

 gray pruinescent area, the central arm occupying the median line of 

 the body, the outer arms lying parallel and close to the median vitta, 

 these areas occupying the interspaces between two linear intermedi- 

 ate and two broad lateral stripes that are polished black; median 

 area of scutum, most of the scutellum and the postnotum heavily 

 yellowish gray pruinose. Pleura black, sparsely pruinose. Halteres 

 pale yellow throughout. Legs with the coxae black, gray pruinose; 

 trochanters obscure yellow; femora black, the bases conspicuously 

 yellow, narrowest on the fore legs, slightly broader on the posterior 

 legs; remainder of the legs black. Wings with a faint yellowish tinge, 

 cells C and Sc slightly brighter; stigma small, oval, brown; very 

 narrow and indistinct brown seams along the cord and outer end of 

 cell 1st 2I2', veins dark brown. Venation; Sc long, Sc^ extending to 

 beyond the fork of Rs, SC2 at the extreme tip of Sc^; Rs long, angulated 

 and spurred at origin ; R2+3 long, about twice as long as the deflection 

 of Cu^; inner end of cell R^ pointed; r near tip of R^, the latter beyond 

 it about one and one-half r; cell M^ present, its petiole about equal 

 to or one-half longer than the basal deflection of Cu^, the latter rather, 

 close to the inner end of cell 1st J/,, the distance about equal to or 

 less than r-m. 



Abdomen dark brown, sparsely pruinose; hypopygium shiny black. 

 Male hypopygium with the pleurites very short and stout, contiguous
