HORSEFLIES OF THE SUBFAMILY TABANINAE 167 
Tabanus quinquevittatus Wiedemann, Diptera Exotica, pt. 1, p. 84, 1821; 
Wiedemann (? not Wiedemann), Aussereuropaische zweifliigelige Insekten, 
v. 1, p. 178, 1828; Bellardi (? not Wiedemann), Saggio di ditterologia 
messicana, pt. 1, p. 65, 1859; Osten Sacken, Smithsn. Misc. Collect. No. 270, 
pp. 228-229, 1878; Hine (? not Wiedemann), Ohio Nat. 7: 26, 1906. 
Types.—A male and a female in the Winthem collection, Vienna. 
Type locality —Savannah. 
Osten Sacken examined the types and found them to be very poor 
specimens but “exceedingly like costalis.” It is doubtful that the 
Mexican specimens, one described by Wiedemann in 1828 and the 
other by Bellardi in 1859, are the same as Wiedemann’s original 
Savannah material. Hine identified a yellowish form of Z'abanus 
lineola Fabricius as quinquevittatus. The writer does not believe that 
Hine’s form should be given specific rank, and it is very doubtful that 
this is the same as the original guinquevittatus material. Since the 
species belongs to a very difficult group, the name cannot be given to 
any species until a further study is made of the types. 
Therioplectes susurrus Marten, Canad. Ent. 15: 111-112, 1883. Tabanus 
susurrus Hine (? not Marten), Ohio Nat. 5: 244, 1904; Philip, Canad. 
Ent. 67: 94, 1935. 
Type.—Female, no longer in existence. 
Type locality —Montana. 
The original description is inadequate, and it is doubtful that Hine 
correctly determined material under this name. For a discussion of 
this species see Philip’s paper. 
Tabanus tetropsis Bigot, Mem. Soc. Zool, France 5: 681-682, 1892. 
Type.—A male in the British Museum. 
Type locality —Georgia. 
This is evidently a Stenotabanus and perhaps the male of S. 
floridensis (Hine). However, until the type can be studied, or the 
male of floridensis discovered, the name had better be left in abeyance. 
Tabanus vicinus Macquart, Diptéres exotiques nouveaux ou peu connus, v. 1, 
pt. 1, p. 148, 1838. 
Type.—Female, collection unknown. 
Type locality—Carolina. 
Not recognizable from the original description.
