NO. 3 NEOTROPICAL FLIES, TABANIDAE — FAIRCHILD 5 



cussed by Bequaert (1940). Several other names are Nearctic and 

 cataloged by Philip ( 1947) . Names omitted by Krober are so indicated 

 here, except in the case of those originally published with no locality 

 or a non-Neotropical locality. 



The type material of the following 64 species was not found either 

 in London or Paris. The species are listed below alphabetically, with 

 place and date of publication, locality, and collection as originally given 

 where this information is available to me. Several names are homo- 

 nyms and so indicated. Species for which no locality was originally 

 given, or where the author states his ignorance of the provenance 

 of the specimen, are indicated by "Loc. ?." In many cases these species 

 may not have been Neotropical, and in the case of the collection at 

 Paris, no search of the Old World or Nearctic collections was made 

 for them. In London, the card catalog of types w^as checked, and 

 so it is reasonably certain that Walker's species now missing from the 

 collections are truly lost. In some cases additional notes on status have 

 been added.
