SYSTEMATIC ARRANGEMENT 
strong spines at the tip placed at right angles ; the 
hasal joint of the tarsi in these legs is singularly 
dilated at its internal base into a strong horny and 
toothed plate ; the posterior tibiee are clothed with 
fulvous hairs ; the wings are pale brown, the hasal 
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 tile peculiar direction of 
the suhapical nerves of the wings.”
