Tacliina tiiirht [ihid. p. 2S7. — Brazil) is a Phorocera. — 

 Vide supra, nmler T. chryaott'/iis. 



Tachhia atnittila [Ibid. p. .'K)5. — Brazil) is a Phorocera. 



Tachinit rujicornis {ihid. p. 30 1. — S. America) is a dhryso- 

 tachiuft, Br. & von Berij. The Museum collection contains 

 two specimens of this species from Atoyac and Teapa, 

 Mexico (presented by Messrs. Godman 6,- Salvin), which 

 were assij^ncd by van der Wnlp ( IJioI. Centr. Anier . Dipt., 

 Suppl. p. ^SO) to Gi/mnor/it/'fa a/redo, Lw. 



Sarcophoga parvu {ibid. p. 321. — Para, Brazil) is not a 

 i^arcophoffa. The species should pcrha|)s be assij^ned to the 

 " Section" Paraniocru/n/chia, Br. &; von Herji;., hut the ty[)e 

 and solitary representative is in such poor condition that it 

 is impossible to be certain as to the jijenus. The face is 

 narrow and somewhat recedino^, otherwise the species might 

 |)crhaps be regarded as allied to the genus Sjj/iixapafa, 

 Bond. 



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

 p. 720. — Nova Scotia) is an Archijtas. Walker's name is 

 given hy Aldrieh {Cat. N. Anier. Diptera, p. 480) as a 

 synonym of Arcfiytas {Jurinia) lateralis, Macq., but at any 

 rate the type is not conspecitic with spicimens in the 

 Museum collection determined as belonging to the latter 

 species by Prof. Tyler Townsend ; the pile on the face in 

 Walker's type is golden yellow instead of black, the 

 second, third, and fourth joints of the front tarsi are innch 

 more cxi)anded, and the pollinosc covering of the thorax and 

 seutcllum is denser and deeper yellow. It may he noted, 

 ht)wever, that according to Macquart the pile on the face of 

 A. lateralis is white (" Face d'un jaune pale, fl dnvet 

 blanc"), so that Townsend's identification is probably 

 incorrect. 



Tacliina speculifera {ibid. p. 731. — N. America), of which 

 the type is a female, is a Micropalpus, Macq. {Linncemyia, 

 Bob.-Desv,), near M. pictiis, Mg. In neither of these 

 species are the palpi reduced to mere stumps. 



Tachina degenera {ibid. p. 732. — Hudson's Bay) is an 

 Ernestin, Rob.-Desv. Contrary to Walker's statement, the 

 eyes are hairy. 



Tachina inrlnbusis iibid. p. 7 1"?. — Florida) is .i Plimnrrni.
