I. — Catalogue of the described South American Species of 

 Calyptrate Muscidse, 



BY C. H. TYLER TOWNSEND. 

 Eead June 6, 1892. 



The present catalogue is offered in the hope that it will materially 

 facilitate the study, in this countr}^, of the South American Calyp- 

 trate Muscidse. Though it doubtless contains much synonymy, 

 which it is impossible to clear up at the present time, it will never- 

 theless serve as a valuable basis for future study of the group. 

 Much time has been spent in its preparation, and the references 

 have been carefully compared. Most of the synonymy advanced by 

 various authors has been included, so far as met with. With the 

 quite extensive literature which has been at the writer's command, 

 it is hoped that the catalogue will be found almost complete up to 

 the present time. For obvious reasons, most of the new genera of 

 Brauer and von Bergenstamm, belonging to South America, are in- 

 cluded and made to embrace the species referred to them, since these 

 authors have critically examined many of the older types and their 

 decisions will have much value in the final placing of the species. 

 So far as possible, a certain natural (?) order has been observed in 

 the sequence of the genera. It is possible, however, that in some 

 cases even the family position of a genus may be misconceived, 

 owing to a more or less incomplete understanding of many of the 

 recent genera.
