During the period Xovember, 1918, to January, 1920^ 

 onh^ the following species were taken, T. circumdatus, T. 

 dubiosus, T. cyaneus. T. mastersi and T. australicus. 

 The first named was the onlj^ species at all plentiful and 

 then only diu-ing March and April, 1919. A few specimens 

 were taken in May, 1919, after wnich no more were seen 

 until October. Dming the later months of 1919, and the 

 beginning of 1920, they remained extremely scarce, prob- 

 ably owing to the severe drought. T. circumdatus was 

 found to be most plentiful in country thickly timbered 

 with wattle and in the vicinity of scrubs even though 

 several miles away from permanent water ; the two striped 

 Tabanids, T. mastersi and T. australictis were usually taken 

 along the river. Many attempts Avere made to discover the 

 breeding habits of these Tabanids but the few larvse discoA - 

 ered in the muddy sand at the edge of the river water ha\ e 

 so far yielded only luicommon species of Tabamis and 

 Silvius. 



Captured Tabanids were kept in captivity and fed on 

 nodules when the latter were obtainable. The flies were 

 fed on honey and water, dates (when procurable) and 

 raisins. They usually lived well on this food and one 



*Tho.-ic .species marked thus were identifitd for us by Dr. E. \W 

 Ferguson.
