second more so than Hrst, and clotlied with golden hairs ; venfei" blackish, 

 dark leddish-biovvn towards the aj)ex, tonientuni grey, [nibescence [)ale,

Leijs. — Femora and tarsi black, basal two thirds of fore and basal

 base of the discal cell; veins dark brown; stigma yellowish, inconspicuous; 

 a long appendix present; base of wings tinged yellow; halteres dark

Ohs. — A small but striking species on account of tlie golden dorsal 

 pubescence. It may be distinguished from 7'. antecedens, Walker, by the 

 thoracic and abdominal ornamentation and the tibia?. There is also a 

 certain resemblance to 7'. oculatiis, Ricardo, in the thoracic clothing but it 

 appears to be distinct. 



Halt. — Gienbrook Creek and Norton's Basin, Nepean River, New 

 South Wales. (Collector and donor. — A. Musgrave, Oct. 1915). 



Two other specimens also from New South Wales — one from 

 Dauedoo, the other from Sydney may possibly belong to this species but 

 differ in some essentials, and may be characterised as follows : — 



Vur. A. Antenna' bright reddish-brown, annuli black ; palpi paler 

 than in the tj^pe ; abdomen reddish-brown, except the first and last three 

 segments blackish, segmentations pale ; second segment Avith a median 

 black sjjot not reaching the ])osterior margin and segments two to five 

 with indistinct apical grey triangular spots. 



Hub. — Dunedoo, New South Wales. (Collector. — W. W. Thorpe, 



Var. B. Antenna; entirely pale reddish-brown ; palpi creamy, and 

 the abdomen similar to Var. A. but lacking the apical triangular spots on 

 the abdomen. 



Ohs. — 1 am disinclined to separate these specimens as distinct species 

 in the absence of more specimens, as they resemble the typical form too 

 closely in shape, color of legs and thorax. Tlie wings are also similar to 

 the type. 



Hah. — Sydney, New South Wales. (Collector and donor. — A. 

 Musgrave).
