Of Tabanus ruficrus, as met with in the Congo Free State by the 

 members of the expedition of the Liverpool School of Tropical 

 Medicine to the Congo, 1903-05, Dr. Todd writes* : " This fly was 

 caught only near water, usually while attempting to bite passengers 



in canoes or steamers They fly very rapidly and strongly, 



and have been seen at over 100 yards from the banks of the river. 

 They seem to be very local. For example, near Pania Mutombo ten 

 or a dozen were seen at the same moment darting about a canoe. 

 A little further down the river towards Lusambo none were seen for 

 miles." Writing with reference to this species in French Congo 

 M. Roubaud saysf : " Common, especially in October, disappear- 

 ing during the remainder of the year, then reappearing in October 

 at Brazzaville, and invading houses and stables ; bites human beings 

 on the rivers." 



It may be noted that Tabanus pervasus, Walk., and T. deyrollei, 

 Big., are synonyms of this species.
