Note. — 0. hunteri, Macleay, and stricta, Erichson, 

 are not included in the above key ; they may be distinct 

 species or varieties, or they may be identical with any of 

 the other species, but no specimens are to hand that can 

 in any way be associated with their respective descriptions. 

 The two species described by Mr. Hill have their scutellar 

 spines inadequately described, and therefore their position 

 in relation to the above key cannot be ascertained at pre- 

 sent. 



Odontomyia scutellata, Macquart. 



PI. VITL, fig. 2 and 3. 



Odontomyia scutellata, Macquart, Dipt. Exot., suppl. 1, 

 1846, p. 52, PI. v., fig. 7. Id., White, Proc. Roy. 

 Soc. Tasm., 1914, p. 59. Id., White, P.L.S. N.S.W., 

 xli., 1916, p. 91. 



Stratiomyia scutellata, Walker, List Dipt. B.M., v. suppl- 

 1, 1854, p. 55. 



Status. — No doubt can exist about the correct identi- 

 fication of this species. White took it just prior to the 

 time he left Tasmania, but one specimen, in bad preserva- 

 tion, was in the Tasmanian Museum collection; later 

 several isolated specimens were taken, and more recently, 

 when more was known about their habits, a long series 

 was obtained. 



Ilab. — -New South Wales, Victoria, and Tasmania. 



Odontomyia later/ mariilata , Macquart. 



PI. VIII., fig. 4. 



Odontomyia lateriinaculata, Macquart, Dipt. Exot,, suppl. 

 4,' 1850, p. 49. ? Id., White, Proc, Rov. Soc. Tasm., 

 1914, p. 58 (male only). ? Id., White, P.L,S. 

 N.S.W., xli., 1916, p. 94 (male only). 

 Status. — White's identification of this species requires 

 confirmation. White identified it as the larger of two 

 similar species, both of which occur in Tasmania as well as 

 on the mainland of Australia. The two species, 0. carini- 

 faries, Macquart, from Tasmania, and 0. lateriniaculata, 

 Macquart, from Australia, are not to be separated by Mac- 

 quart's descriptions; both are described from the male,
