gained in maintaining them as distinct species. I 

 may add that Mr. Sloane very kindly re-examined 

 his types and the other specimens while on a recent 

 visit to Sydney, and was of the opinion that the 

 specimens were all one variable species with the pos- 

 sible exception of the 9 type of T. cequalis, 

 which has in addition to other slight differences a 

 slightly different impression on the fifth ventral 

 segment. 



Hab. — Western South Australia, most of the 

 specimens labelled "Elder Expl. Expedition, May- 

 June 24, 1891. Helms." A specimen of T. helmsi (so 

 labelled by Mr. Sloane) is from Everard Range, one 

 of T . cequalis is from Barrow Range, while the 9 

 type of T. caqualis is from Fraser Range.

 €1. Talaurinus, sp/ 2 ) — Several specimens of a species be- 

 longing to the semispinosus group. As I am not at 

 all certain of the identity of several species of this 

 group it seems best, to avoid further confusion, not 

 to describe these specimens for the present. I have 

 this species from Eucla; the South Australian 

 Museum specimens are from Eyre Sandpatch.

Blue Mountains. 



63. Talaurinus bubaroides, n. sp. 



64. Talaurinus spiniger, n. sp. 



65. Talaurinus rugifer, Boisd. — New South Wales: 



Sydney. 



66. Talaurinus impressicollis, Macl. — Victoria. A single 



9 from Blackburn's collection sent under the 

 synonym hiscipennis, Macl.
