In January, 1917, an experimental station was established at 

 Kendall in the Camden Haven district for the study of the 

 means of transmission of Onchocerca gibsoni in cattle. During 

 the course of the last three years, while these investigations 

 were being carried on, special attention was paid to the Tabani- 

 dae as possible vectors of the larvae whether as mechanical trans- 

 mitters or as intermediate hosts. Collections of these flies were 

 made for identification and reference, and examination of the 

 material at our disposal shows that many of the species collected 

 are apparently undescribed. Descriptions of the new species 

 will be found in the following paper together with a record of 

 all the species obtained with such notes on the times of occur- 

 rence, place of capture, etc., as are available. 



Kendall lies on the Camden Haven River, which runs to the 

 north of the West Brother; the valley of the river is practicably 

 surrounded by high hills; along the river are rich flats devoted 

 to dairying, with stretches of uncleared bush and patches of 

 jungle in the gullies; near Kendall there is also a good deal of 

 marshy ground, while lower down, the river flows through Wat- 

 son Taylor's lake before entering the sea. The locality is pre- 

 eminently suitable for the study of Tabanidae as is evidenced 

 by the number of species (41 ) obtained. Many of the species 

 were taken around the cows in the dairy yards, but others were 

 only obtained in the bush and were rarely or never found in the 

 vards .
