Limnobia atridorsum is a species that might be referred with 

 almost equal propriety to either Limnobia or Dicranomyia. 

 Its closest relative seems to he L. japonica (Alexander) of Japan.

A small series of both sexes taken at Shishito, Formosa, 

 May 25-26, 1917 (T. Shiraki) No. 1345. The specimens agree 

 well with the type of A. javanensis, although there are, in some 

 specimens, three feebly-defined brownish stripes on the prae- 

 scutum. This is presumably the species mentioned by Edwards 

 from Horisha, Formosa (Ann. Mag. Nat. Hist., ser. 8, vol. 18, 

 p. 249), although the species is very much smaller than the 

 European A. vitripe?mis (Meigen). The male sex has not been 

 described and one of the present specimens is hereby designated 

 as allotype. 



Allotype, cf. Male hypopygium with the dorsal pleural appendage 

 cylindrical, chitinized, the apex truncated and with a small rounded 

 notch; ventral appendage fleshy with nvimerous coarse bristles. 



Male — Length 4-4.1 mm.; wing, 4.3-4.5 mm. 



Allotype, cf, Shishito, Formosa, May 25, 1917. 



Styringomyia Loew. 

 Styringomyia flavitarsis sp. n. 



General coloration shiny black; legs black, the posterior tarsi 

 obscure yellow; wings dark brown. 



Male — Length, 7.8 mm.; wing, 6.1 mm. 



Rostrum and palpi dark brown. Antennal scape brownish black; 

 basal flagellar segments dark brown, the remainder brownish yellow, 

 the segments rather elongated. Head brownish testaceous.
