New or Lillle-known Exotic Tipulidae. 41 



fork of i?2 + 3 ; i?2 + 3 a little longer than the deflection of ii4 + 5 ; 

 r — m slightly longer than the basal deflection of i?4 + 5 ; basal 

 deflection of Cn\ inserted immediately before the fork of J/3 and 

 Cu\, the fusion of the latter punctiform. Almost the entire wing- 

 surface is covered with conspicuous macrotrichiae, this including 

 all the cells beyond the cord, all of cells R and M except the bases, 

 the distal fourth of cell Cxi and the distal half of the Anal cells. 



Abdomen dark broA\Ti. Male hypopygium small but not con- 

 cealed within the body as in other species of the genus. 



Hah. Paraguay. 



Holotype, ^, San Bernardino [Fiebrig). 



Paratopotype, ^. 



Type in the collection of the Vienna Museum. 



Gonomyia (Progonomyia) dolorosa, sp. n. 



General coloration black; thoracic pleura with a narroAV white 

 longitudinal stripe; legs bro\^Tiish black; wings suffused with 

 broAvn, the stigma darker brown ; Sc long, Sc2 some distance before 

 the tip of Sc\; male hypopygium with three black pleural 

 appendages. 



Male. — Length about 6 mm. ; wing 6-2 mm. 



Female. — Length about 6"5 mm. ; wing 6*3 mm. 



Eostrum and paljDi black. Antennae black, the distal flagellar 

 segments elongate. Head dark, grey pruinose. 



Pronotum broadly black medially, paler laterally. Mesonotum 

 black; humeral region and lateral margins narrowly whitish; a 

 whitish area on the postero-lateral portions of the praescutum ; 

 median area of scutum and the scutellum suffused with reddish. 

 Pleura broA^aiish black with a narrow white longitudinal stripe 

 occupying the dorsal margin of the mesosternum, beginning im- 

 mediately behind the fore coxae passing above the mid-coxae, 

 ending at the posterior coxae. Halteres obscure whitish testaceous, 

 the knobs darker. Legs dark browaiish black, the coxae paler 

 terminally. Wings VAdth a strong brownish suffusion, the stigma 

 darker brown, oval ; veins dark brown. Venation : Sc long, ^S'cl 

 ending opposite mid-length of Rs, Sc2 some distance from the 

 tip of Scl, Scl alone a little longer than the basal deflection of 

 Ciil ; r faint, inserted at about four- fifths the length of R2 + 3, 

 the latter a little shorter than the petiole of cell 2nd M2; basal 

 deflection of Cu\ a short distance before the fork of M. 



Abdomen black, the tergites very narrowly margined caudally 

 with paler. Male hypopygium black; pleurites triangular, the 

 apex of each produced into a short black point ; three dark-coloured
