the apex and centres of fourth and fifth cells and axillary 

 lobe being hyaline. 



Psilozona nigritarsis, sp. n. 



Three males from Townsville^ Queensland {F. P. Dodd), 

 1903. 



A species very similar to P. albitarsis, but distinguished, 

 by the pale ivings, the absence of white hairs on the fore 

 tarsi, and by the presence oifuiir black bristles on the breast- 

 side just above the transverse suture in the type only. The 

 moustache has more yellow hairs and fewer black bristles, 

 the colouring on sides oi face is golden yellow ; the hairs on 

 palpi, on lower part of the first two antennal joints, com- 

 posing the beard, and round head are yellowish. Thorax 

 not quite so pubescent. Abdomen with whitish pubescence 

 only at base and a little short, scattered, white pubescence on 

 the apex. The pubescence on fore legs less thick. 



Length 18 mm. 



Damalis, Fabr. 

 Sjst. Antl. p. 147 (1805). 

 Only one species is recorded from Australia : — 



Damalis fuscipennis, Macq., Dipt. Exot. Suppl. 1, p. 222 

 (18^4). 



This must be nearly allied to Damalis pandens, Walker, 

 Proc. Linn. Soc. London, iv. p. 101' [Discocephala] (1860), 

 from Celebes, the type in the 13rit. Mus. Coll. ; but that of 

 Damalis lugens, Wlk., from New Guinea, is not to be found. 



Doleschall recorded one species, Damalis erythrophthulmus, 

 from Amboina. 



Ancylorrhynchus, Latreille. 



Fam. Regn. Anim. p. 490 (1825). 



Xiphocera, Macq., ISuites a Eiiffon, i. p. 279 (1834). 



See Kertesz, Cat. Dipt. p. 100, for other synonyms. 



This genus has not been recorded from Australia itself. 

 All the Walker species placed in it in Kertesz's Cat. belong to 

 other genera ; v, d. Wulp records one species from the Island 

 of Waigou, X coinplacita, and Doleschall one from Amboina, 

 X. rufitlwrax.
