Hah. S.A., Adelaide, Kangaroo I.. Coorong, Yeelanna. 

 In the Annals and Magazine of Natural History, 1917, p. 224, Miss Ricardo 

 records the presence of T. postponens in South Australia, basing her determina- 

 tion on specimens in the South Australian Museum. Examination of this 

 material, which is before me, shews that two distinct species have been included, 

 one probably T. circiimdatus. the other the present species. 1 am separating it 

 from T. postpuuois as it does not agree with specimens in my own collection
