Generic Position of certain MusciJ*. 3H7 



(Ami. Soc. Ent. Vr. 1888, p. 2G8).— The facial ridj^es in 

 Walker's type are not bare, as stated by Walker, but are 

 soniewLat sparsely ciliated up to the middle. 



Masicera gentica (ibid. p. 302. — Mexico) apparently 

 belongs to Cerojnasia, — sensii Br. & von Berg. The type is 

 now a mere fragment. 



Tachina anciUa (Ins. Saund.— Dipt. iv. (1852) p. 299.— 

 United States) is correctly assigned by Coquillett (Rev. 

 Tachinidae, p. 10(5) to tlie genus Frontina, .Mg. 



Enrigaster sayinata (Trans. Ent. Soc. Lond. n. ser. v. 

 (1861) p. 298. — Mexico) does not belong to Exorista, to 

 which it is referred by Aldrich {op. cit. p. 459). The head 

 of the type is missing, and the genus must therefore remain 

 uncertain, but the species must apparently be a'osigned to 

 the " Section " Plagia, Br. & von Berg. — Costal spine 

 wanting; third vein bristly as far as the small transverse 

 vein ; posterior transverse vein much more oblique than the 

 apical portion of the fourth vein, which is very abruptly 

 bent up; bend of fourth vein with a very small appendix; 

 abdominal macrochsetge marginal. 



Tachina ampelus (List Dipt. Ins. Brit. Mus. iv. (1849) 

 p. 732. — Nova Scotia) is an Ernest ia {Panzeria of Coquillett 

 & Aldrich), but is not synonymous with radiciim, Fabr., as 

 erroneously stated by the American writers. — It would 

 appear from the fact that specimens ot another species in 

 the .Museum collection, from "\'ernon, British Columbia, 

 April to May, 1902 (Miss Ricardo), were determined by 

 Coquillett as " Panzeria radicum, Fabr.," but have in realitv 

 nothing to do with that species, that the interpretation of 

 Musca radicvin, Fabr., by American authors is incorrect. 

 Miss Ricardo's species is one of two species of Eniestia 

 obtained by her at the same locality, and both remarkable 

 for the smallncss of the eyes. The species wrongly identified 

 by Coquillett has the abdomen unicolorous shining bronze- 

 black, while in the other the second, third, and fourth 

 segments have a polliuose band in front. 



Tachina aids {ibid. p. 710. — Locality unknown) = Hystricia 

 (Tachina) signata, W'alk. (op. cit. p. 709), from New Zealand. 



Tachina metallifera (ibid. p. 717. — Locality unknown) is 

 an Archytas. 



Tachina damippus (ibid. p. 719. — Locality according to 

 the " List " unknown, but from a label on the specimen — 

 }k[e\\co)=^Archyias ana/is, Fabr.
