This narrow-bodied mummy-brown species, measuring 

 12-13 mm., comes from Queensland. Palpi long and 

 slender. Forehead narrow, parallel, frontal callus oblong, 

 raised, with a lineal extension. Abdomen Avith a yellow-

Group VIII. 



Species with median or lateral spots, or both, on abdomen, not usually 

 forming a continuous type. 



Tabanus propinguus, Macquart, Dipt. exot. Suppl. v. p. 47 

 (1854), described as in Mr. Bigot's Coll. from Sydney, is 

 probably lost, as it is not among the types sent me by 

 Mr. Collins from the late Mr. Yerrall's Coll. It is described 

 as black with three series of white spots on the abdomen. 

 Legs black, tibiae testaceous. 



Length 18 mm. 



Part of the abdomen was wanting when described. 



Tabanus leucophilus, Walker, List Dipt. i. p. 154 (1848). 



Type (female) from J^3ew Holland. 



A stout species with pale whitish wings, abdomen blackish 

 with three rows of white spots. Antennae reddish. 



Length 19 mm. 



A species very easily recognized. Is it possible that it 

 does not belong to this region at all? I have seen nothing 

 like it as yet in collections from Australasia, 



Face covered with ashy-grey tomentum and with long 

 pale yellow hairs. Palpi canary-coloured, stout, ending in 

 a short point, pubescence apparently black. Antenna broken 

 off, described by Walker as ferruginous, the first two joints
