NOTES AND SYNONYMY. 



Theria R. D. — Brauer and v. Berg, say (Muse. Sch. ii, 68) that 

 " Eurychaeta v. d. Wulp, B. C.-A." is a synonym of this genus. 



Sarcophila Rdi. — This genus, though not at present identified fron) 

 North America, will very probably be found here. 



Myophora Rob. Desv. Myod. 337. — Syn. of Sarcophaga Mg. 



Onesia Rob. Desv. — This genus, in all probability, will yet be found 

 within our limits. It may seem difficult at times to distinguish 

 it from Lucllla and other Muscid genera. The following char- 

 acters will serve to identify it : Arista naked on apical half; 

 bristles (macrochsetse) on the last two segments of the abdomen, 

 while in the Muscida^ s. str. the last .segment at mo.st has bristle- 

 like hairs ; no species have the gold-green colors of Lucllia, etc. 



Brauer and von Bergenstamm (Muse. Sch. ii, 62, [366] ) mention 

 the genus " Trichoprosopiis v. d. Wulp, (?Mcq.)" as belonging 

 with the Sarcophagidie. This seems to have been a fly received 

 by Br. and v. Bgst. from Mr. v. d. Wulp, apparently labeled
