330 SYSTEMATIC ARRANGEMENT 



strong spines at the tip placed at right angles ; the 

 basal joint of the tarsi in these legs is singularly 

 dilated at its internal base into a strong horny and 

 toothed plate; the posterior tibiae are clothed with 

 fulvous hairs ; the wings are pale brown, the basal 

 lobe large and nearly black, the apical half of the 

 wing brown with the nerves margined-, especially 

 at the hinder margin of the wing, with whitish ; the 

 third and fourth segments of the abdomen are fur- 

 nished with a pair of tufts of black hairs; there 

 is also a pair of more minute tufts on the fifth seg- 

 ment ; halteres black. 



Inhabits New South Wales. In the collection of 

 the Rev. F. W. Hope. 



" I have only seen/' says Mr. Westwood, who 

 furnished the drawing of this insect, " males of this 

 curious species. I possess another still larger species 

 of Asilus from New Holland, agreeing with the 

 preceding in the broad and flattened abdomen with 

 lateral tufts, and which is evidently the Asilus 

 Coriareus of Weidemann, (Auss. Zweifl. Ins. 2, p. 

 644,) although the description of that author being 

 derived from a solitary and mutilated specimen is 

 necessarily incomplete. Of this species I have only 

 seen females; and I have but little doubt that the 

 insect here figured will ultimately prove to be the 

 males of Weidemann's insect, notwithstanding the 

 great diversity in their colours and general appear- 

 ance. Both also agree in the peculiar direction of 

 the subapical nerves of the wings/'
