CATAI.OGIIE OF THE HE^CRIBED SPEC’IES OF 
SOUTH AMERICAN ASIEID.E. 
BY S. W. WILLISTON. 
'File following preliminary catalogue of the described species of 
South American Asilidse is offered in the hope that it may lighten 
the labors of students of the South American Dipterous fauna. It 
was originally prejiared, two years ago, as a preliminary to the study 
of a Brazilian collection in this family, and has been recently sub- 
jected to a careful revision. It will be strange if, among so many 
references, some errors, both of omission and commission, are not 
found. I can only say in extenuation of such, that the entire paper 
has been repeatedly written and the references as often compared. 
Schiller’s list of specific names of the Asilidie of the world, which 
seems to be very complete to 1860, has been of material service, as 
also Lynch’s partial catalogue. The distribution of the genera is 
chiefly that of Schiner ; some few changes have been made in ac- 
cordance with Lynch’s, Osteu Sackeu’s, or my own views. A very 
few of the less important works have been inaccessible to me, and it 
is in them that additional references may be found. The references 
thus taken at second hand will be found preceded by an asterisk. 
No references later than 1889 are included.
