in these publications, it was considered advisable that the Tabanidae of 
Louisiana be studied, not only because of the direct damage they caused 
to livestock in the State on account of their blood sucking propensities, 
but also because of the suspicion that they were instrumental in the spread 
of anthrax or charbon, a dread disease of livestock. In 1920 the Taban¬ 
idae, because of their importance, were again made the subject of a project 
of the Louisiana Station and it is our purpose to here record briefly the 
progress of this project insofar as the observations made supplement 
the reports of Professor Hine. 
Additional Species Collected in the State 
Besides taking the majority of the forty species recorded by Hine 
as having been found in the State we have collected several others. 
These include the following, specimens of all of which have been identi¬ 
fied by Dr. J. M. Aldrich of the United States National Museum:— 
Diachlorus ferrugatus Say, Chrysops montanus O. S., Tabanus cerastes 
O. S., T. flavins Macq., T. giganteus DeG., T. lasiophthalmus Meg., 
T. longiusculus Hine, T. remwardtii Wd., T. sty gins Say, T. turbidus 
Wd. Additional species, determined by Professor J. S. Hine, are:— 
Chrysops separatus Hine, Tabanus fuscopunctatus Macq., T. imitans 
Walker, and T. aequalis Hine. 
Observations on Adults of Additional Species Collected 
Two adult females of Diachlorus ferrugatus have been collected. One 
was taken at Baton Rouge (Apr. 25) and the other at Lutcher (July 2). 
Two females of Chrysops montanus have been taken in woods at 
Magnolia (East Baton Rouge Parish) while flying about the collector’s 
head. One was taken between 5:00 and 5:30 A. M. (May 16) and the 
other later in the day (May 15). A female adult of Chrysops separatus 
was noted feeding at the base of a cow’s ear at Baton Rouge on April 7, 
1922. 
An adult male of Tabanus lasiophthalmus was found in a greenhouse 
at Baton Rouge on March 28, 1922. 
A female of Tabanus stygius has been taken at New Orleans (Aug. 15) 
and another has been collected from a mule at Baton Rouge, (May 10). 
From this same host and in this same locality single females of Tabanus 
cerastes (May 16) and Tabanus giganteus (July 28) have also been se¬ 
cured, while females of Tabanus longiusculus have been observed feeding 
on horses near and in woods at Mound (June 29). 
Tabanus flavus, a species whose body is of a pale yellowish tinged 
with green, resembles Tabanus mexicanus Macq. in appearance and the
