462 NOTES ox AUSTRALIAN TABANIDAE. 



compareil witli the type (K.W.F.) from Kalamunda, Western Australia, in the 

 British Museum. 



We associate with this specimens from Lake Hattah, "\'ictoria; Narrabri, 

 N.S. Wales; and Springsure and Burnett River, (Queensland. The New South 

 Wales and Queensland specimens show some slight difference in that the forehead 

 is sUghtly narrower and the antennae are rather lighter. The Burnett River 

 specimens {d, ?) were bred out by Miss Bancroft and bear a label: — "Bred from 

 larvae found in wet sand at river edge, Burnett R.. 18.11.19."' They are in 

 excellent preservation^ and the abdominal clothing is much more marked than in 

 our other specimens, in which it is somewhat abraded. Through them we were 

 able to associate Silriits psarophanes with S. notatus; the former species being 

 identified with the Burnett River male. Males and females of psarophanes have 

 also been bred out in Towiisville (G.F.H.) and correspond with the Springsure 

 and Burnett River specimens. 



S. fuliginosvs Taylor, of which we have examined the type and compared it 

 with our series of .S. notatus, appears hardly separable. It is somewhat smaller 

 and the forehead is •distinctly nan-ower than in the Victorian specimens, in which 

 respect the New South Wales and Queensland specimens are intermediate. The 

 antennae and legs are decidedly lighter in colour than in the Victorian specimen, 

 but Iiere again it is linked up by the intei-mediate specimens. We are inclined 

 to regard it as not being specifically distinct, though it may be necessary to re- 

 tain the name as a subspecies. Further specimens from the Northern Territory 

 will probably be necessary to settle the status of S. fi(h'(}itwsvs.

AVe ha\e examined the types of Tayloi's species and other specimens from the 

 same district (G.F.H. ), and cannot find any valid reason for maintaining tliem 

 as distinct. The ty])e of S. tahaviformis has more conspicuous clothing, but the 

 type of .s'. sordidiis is certainly considei-ably abraded. The colour of the abdomen 

 is somewhat lighter in tahaiiiformis, but the type is apparently an immature speci- 

 men. 



In his description, Taylor states that the inner margins of the eyes in S. 

 sordidus are parallel, while under S. tahanifonnis he states that the inner margins 

 are slightly convergent towards the base. The difference, however, when the two 

 types are compared is inappreciable.

This si)ecies was originally described from the Aru Islands, and a s|icciiiu'ii 

 in the collection of the South Anstialiaii Museum from Stewart River. Queens- 

 land, was determined by Miss Ricardo. This has been compared with a series of 

 T. uriseohirlus Taylor, including the type, and the species are certainly identical. 

 The series shows some variation in size and in the colouration of the clothing, a 

 specimen from Kimberle\ perhaps i-epi-esenting a vaiiety. but too closely allied 

 to be separated. The sp.iics appears to be wides|.read in the nortli of Au.sfralia 

 and in the islands immediately to the north.
