TAXONOMY OF MUSCOIDEAN FLIES — TOWNSEND 6" 



NEAPORIA, nom. gen. nov. 



This name is proposed for Aporia (Macquart) Brauer and von 

 Bergenstamm, which is preoccupied. The type of the genus is 

 qnadrimaculaia Macquart, of South America. The species lima- 

 codis Townsend seems to belong here also. The latter is distinct 

 from Dc.via pristis Walker in its practically bare arista. D. pristis, 

 so far as can be judged from the description, is not a Macquartia 

 s. str. Mr. E. E. Austen has referred it to Aporia (Ann. Mag, N. 

 H., ser. 7, vol. xix, p. 344). 



RONDANIMYIA, nom. gen. nov. 



This name is proposed in honor of Camillo Rondani for his genus 

 Gynniopsis (Dipt. Ital. Pr., 111, 1859, pp. 90-91), which is pre- 

 occupied by Rafael in Pisces (1815). The type is Macq. chalconata 

 (Wiedemann, Meigen, Zetterstedt) Rondani, of Europe. Brauer 

 and von Bergenstamm retain the species in Macquartia, but it seems 

 preferable to maintain it separately on the characters pointed out by 

 Rondani. 



METHYPOSTENA, gen. nov. 



This genus is proposed for the type of Hypostena barbata Coquil- 

 lett, which can be referred to neither Hypostena, Tachinophyto. nor 

 Pseudomyothyria. There are no bristles on the third longitudinal 

 vein, the small crossvein is almost opposite to the end of the first 

 vein, hind crossvein is in middle between small crossvein and bend 

 of fourth vein, apical cell ends in exact wing-tip. The wings are 

 narrow, their width being much less than one-half their length. The 

 parafacials are narrowed below to a mere line next the lower border 

 of eyes, the facial profile is very oblique and receding, the lower 

 margin of head short, the arista strongly curved.
