These are not types, but the species is the type of Uramyia. The 

 specimens agree exactly with those identified by Townsend in the 

 ISTational Museum, and discussed by me.^ 



GYMNOSTYLIA Macquart 



The status of this genus requires elucidation before proceeding to 

 a discussion of the three species received under this generic name, 



Macquart described the genus in his Histoire Naturelle de Dip- 

 teres.^° He included three species from Eobineau's Myodaires of 

 1830 — Macromya depressa, Earrisia scutellaris, and in a separate 

 division with tomentose arista Leschenaultia cilipes. These were 

 all Brazilian species. No genotype was indicated until 1916, when 

 Townsend ^^ designated Macromya depressa. On the same page he 

 designated the same species as genotype of Macromya Robineau- 

 Desvoidy ^^ which originally contained this and one other Brazilian 

 species. Thus Gymnostylia is a complete synonym of Macromya. 

 The genotype of the latter, depressa, is totally distinct from anything 

 placed in Gymnostylija by Brauer and Bergenstamm. It is a very 

 large, robust, depressed, yellow species, 16 to 18 mm. long, which 

 I have not seen and am unable to place from the meager description 

 (Macquart's description is compiled from Robineau's). 



93. OXYAPORIA ORNATA Braner and Bersrenstamm 



Gi/mnosti/lia ornata Schiner, Beauer and Bergenstamm, Denk. Wien. 

 Akad. Wiss., vol. 56, 1889, p. 128, fig.; vol. 58, 1891, p. 374, desc. ; vol. 

 60, 1893, p. 130. 



One male, type of species, from Venezuela (Lindig, 1864). 

 Schiner never described the species, hence it should be attributed 

 to Brauer and Bergenstamm. They gave in 1891 a good but brief 

 description. The species forms a distinct genus which has been 

 named 



OXYAPORIA Townsend 



Oxyaporia Townsend, Insecutor Ins. Menst., vol. 6, 1918, p. 170; Revista 

 Mus. Paulista, vol. 15, 1926, p. 273. Type designated, Gymnostylia ornata 

 Schiner. 



Elongated and slender, allied to Urodexodes but with parafacials 

 hairy. Hypopleural bristles and post scutellum well developed. 

 Front rather narrow, a little prominent, face moderately receding; 

 eyes bare, rather obliquely placed so that the lower part is consid- 

 erably anterior to back of head; cheek one-fourth the eye height.
