Summary. 



1. An examination of the following flies captured in 

 the Eidsvoid d. strict where worm nodules are known to 

 occur in cattle, failed to reveal the presence of Onchocerca 

 larvae : (1) Tabanus circumdatus (2) T. mastersi, (3) T. 

 dubiosus, (4) T. cyantus, (5) T. australicus, (6) Musca 

 fergusoni, (7) M. vetustissima, (8) M. terrce-regince, (9) 

 Fannia sp. 



^2) The Tabanids, T. circumdatus, T. dubioyiis, T. 

 mastersi, and T. australicus, as well as the thi-ee 

 above named species of Musca and Fannia sp. failed to 

 become infected with lar\ ae when fed on freshly cut worm 

 nodules.
