Genus Limnqphila Macquart. 

 Subgenus Limnophilella new subgenus. 



Similar to Limnophila in the strict sense ; wing-venation with the 

 radial sector angulated or spurred at origin ; r far removed from the 

 tip of R 1 ; basal deflection of Cu 1 before the fork of M ; 2nd anal 

 cell narrow; halteres very long and slender; tibial spurs of medium 

 size ; abdomen elongate. 



Type of the subgenus. — Limnophila cpiphragmoides Alex. 

 (Brazil). The new species described below is congeneric. In prac- 

 tically all the genera and subgenera related to Limnophila the basal 

 deflection of Cu x is underneath the cell 1st M„; in Dactylolabis it is 

 inserted usually at the fork of M. In the two species included in 

 this new group the deflection is inserted on M far before its fork 

 and I have no doubt of the validity of such a group which may 

 include many species when the fauna of tropical America is better 

 known. 



Limnophila (Limnophilella) victor new species. 



General coloration dark brown including the legs and slender halteres; 

 wings subhyaline with a heavy brown pattern ; Rs long spurred at origin ; 

 petiole of cell M ± rather long; basal deflection of C«j slightly before the fork 

 of M ; abdomen with the sternites ringed with brown. 



Female. — Length, 11.4 mm.; wing, 10.2 mm.; halteres, 2.3 mm. Middle 

 leg, femur, 6.7 mm. ; tibia, 9 mm. ; hind leg, femur, 7.2 mm. ; tibia, 9.8 mm. 



Rostrum rather light brown, palpi darker brown. Antennae dark brown, 

 rather elongate for this sex. Head light colored. 



Thorax dark brown, the mesonotal stripes indistinct. Pleura pale testa- 

 ceous with large indistinct darker blotches. Halteres very long, slender, dark 

 brown throughout. Legs dark brown, the femora a little paler at the base. 

 Wings narrow, subhyaline, with a heavy brown pattern ; cells C and Sc more
