HORSE 
SOUTHERN BUFFALO GNAT ( Eusimulium pecuarum Riley) 
United States G. H. Bradley (May): The southern buffalo gnat appeared 
much earlier than usual in the gnat-infested territory this 
year. A few individuals were reported as seen ahout the 
middle of December, 1931. They were abundant about the middle 
of January and were definitely on the decline by the end of 
March. These pests were present in annoying numbers in 
Mississippi. They do not fly far into the hill country east 
of the Delta except along low river bottoms. In Arkansas 
there were records of their presence from many points. In 
Louisiana they were reported at Monroe and as fairly well 
distributed throughout Ouachita Parish, the eastern section 
of Richland and in several sections of Caldwell Parish, also 
at Winnfield and Nachitoches. They were also reported as 
present at Covington, Tennessee. This year the gnats appeared 
in gradually increasing numbers and as is usual under such 
conditions only isolated cases of their killing stock were 
reported.
