This species measures, ¢ 16, 9 21 mm. 
Moustache in the male black and yellow, in the female 
entirely black. 
Male.— Abdomen with yellow-haired segmentations and 
black spots, pubescence yellow. Genitalia with very large

hind pair chiefly black. Tibize the same colour, only the 
hind pair black at apices; all tarsi black, the pubescence on 
legs is chiefly yellow and short, longer on the underside of 
tibize, with long black hairs on the underside of femora; 
some short black pubescence is intermixed with the yellow

Osten-Sacken records a female from Momi, New Guinea. 
De Meijere records the species from Zoutbron and Hol- 
landia, near Humboldt Bay in North New Guinea, and from 
Etna Bay, Dutch New Guinea (South). 
He describes these last specimens as measuring 23 mm., 
and speaks of the fore femora only as being red at the apex 
below.

Trans. Zool. Soc. London, xx. pt. 18, p. 492 (1915).

From Dutch New Gutnea.

Type (male) and type (female) from N.E. Queensland 
(C. M. Kelsall) (1910). 
In the above publication on the Asilide of Australia, I

and that they are a distinct species, the colouring of the 
femora being black above, but red below, and the genitalia
