 Coquillett (Revision of N. A. Tachinidae, p. 108, 1897) believes that it is 

 synonymous with violenta Walker. Aldrich (Cat. Dipt., p. 463, 1905) dis- 

 agrees with Coquillett and makes spMngivora a synonym of dubia Willis- 

 ton. The type has not been seen by the writer, although, from its descrip- 

 tion, the species would fall in the frenchii complex.

 1892. 



Coquillett, in errata attached to revised index to Revision of N. A. 

 Tachinidae, refers this species to Frontina. Aldrich (Proc Ent. Soc. Wash., 

 vol. 32, 1930, p. 25) shows that it is a synonym of the European Ptychomyia 

 selecta Meigen. 

 violenta Walker (Tachina), List of Dipterous Insects, pt. 4, p. 788, 1849. 

 Aldrich has seen the type and places it in Tachinomyia. 

 Coquillett's species is here described as testacea, new species. 

 xychus Walker (Ophelia), Walker's List Dipt. Ins., vol. 4, p. 770, 1849, 

 Jamaica. 

 According to Austen (Ann, and Mag. Hist., ser. 7, vol. 19, p. 332, 1907), 

 xychus is a Frontina. The species is not recognizable from its description.
