The tibiae are reddish with the apical hith blaek, all bristles black. The 

 larei are black, with black bristles and reddish pubescence beneath. 



The mng-s are slifjiitly infumed and have a normal venation; the inter- 

 mediate crossvein is situated before the middle of the discal cell and the second 

 posterior cell is rather long and slightly constricted subapically. 



$. The female is similar to the male; the abdominal bristles are smaller; the 

 ovipositor is short, and contains a cylindrical styliform lamella. The sixth and 

 seventh abdominal segments are black, shining and subcompressed ; sometimes the 

 seventh segment is quite compressed, and both the sixth and seventh segments are 

 as long as the ovipositor. 



Length. — Males, 15 — 16 mm.; females, 13 — 19 mm. 



Hab. — New South Wales: Sydney and Katoomba. (November to .Januaiy.) 



Type. — The holotype male and the allotype female were presented to the 

 Australian Museum by Dr. E. W. Ferguson. They were taken in Sydney, at 

 Eoseville, on the 17th and 8th November, 1919; respectively. There are eleven 

 paratypes, four males and three females from the type locality, also taken by 

 Dr. Ferguson; one male taken at Katoomba during 1912, by Mr. E. Green, a 

 pair taken by Mr. F. H. Taylor in Sydney, and one in the Macleay Museum. 



Note. — This species cannot be made to agree with any description so far 

 published. A. exilis Macquart has bristles on the apex of the male genitalia, but 

 differs according to its description in several respects and is from Kangaroo 

 Island. Asilus villaticiis Walker from New South Wales, and Cerdistus austraUa 

 Ricardo also do not conform to this species, although the latter, and probably tlie 

 former, have bristles on the male genitalia. The females of both these are known 

 to Miss Ricardo, and it is taken for granted that no species known to that author 

 has the sixth abdominal segment of the female ovipositor-like. Both Miss 

 Ricardo and White state that the sixth abdominal segment does not form part of 

 the ovipositor in Australian species. Asihis Jillferus Macquart, from Sydney 

 Island, has also filaments to the male genitalia, but Maequart's drawing of this 

 organ differs considerably from that of the species described above.
