New Australian Tabanidae. A7 



Tabanus edentulus, Macq. (Plate II., fig. 5). 



Macquart, Dipt. Exot. Supp. i., 34, 68, Tab. iii., fig. 13 (1845) ;. 

 White, Papers and Proc. Roy. Soc. Tasmania, p. 10 (1915). 



Mr. White has attached Macquart's name to a species closely 

 allied to T. circumdatus, but I do not know what is his authority 

 for the identification. While in Paris I examined a number of 

 Macquart's Australian Tabanidae, and have the following brief- 

 note on this species : — 



" ' T. cdentidus, Macq., n. sp.' So marked in Macquart's hand- 

 writing, has the eyes' densely covered with white silky pubes- 

 cence, otherwise it is a dark species. I think it is antecedens ac- 

 cording to White." 



I do not now remember my authority for ascribing the hand- 

 writing to Macquart; probably my informant was M. Lesne,. 

 who was so kind as to show me the specimens. I' cannot be cer- 

 tain that the specimen examined was actually the type, as there 

 was no type label. Pending further enquiries I do not propose 

 to sink T. antecedens, Walker, under T. cdemtulus, Macq. 



The species identified by White as T. cdentidus is certainly 

 distinct from T. antecedens, Walker, but for the present I have 

 left the species under Macquart's name. White's paper may be 

 referred to for a full description. 



Typical specimens differ from T. circumdatus in, the noticeably 

 more slender third joint of the antennae; as a rule, it is a 

 smaller, darker species than T. circumdatus, but is variable both 

 in size and colour. 



Further discussion of the variations, both of this species and. 

 T. circumdatus is postponed for the present. 



Tabanus acutipalpis, Macquart. 



Macquart, Dipt. Exot., 1, p. 131 (1838). 



Specimens of a large species allied to T. circumdatus are be- 

 fore me ; they agree with specimens in the British Museum doubt- 

 fully labelled T.. acutipalpis, Macq. 



While in Paris I made the following note on specimens labelled 

 T. acutipalpis: — 



" T. acutipalpis, Macq., Tasmania, seems to me certainly 

 T. circumdatus. Nine specimens, with at least two with labels 

 in Macquart's handwriting." 



Miss Ricardo's notes under T. circumdatus: " Tabanus acuti- 

 palpis, Macq., appears very similar, but is larger in size."
