Within the last twelve months, some hundreds oE specimens of this species, 

 chiefly collected by Messrs. Simpson and Neave, have been received by the 

 Entomological Research Committee from the countries mentioned. In Northern 

 Nigeria, Mr. Simpson, who, like other collectors in the same colony, has hitherto 

 only met with the female, took Tabanus pertmens in large numbers on the polo 

 ground at Zungeru, in November, 1910 ; additional specimens, collected at the
