74 REVISION OF THK STHATIOMYID^ OF AUSTRALIA, 



forked, cubital vein. It also agrees with the European and 

 North American genus AUognosta in having the scutellum un- 

 armedj and in possessing only three, posterior veins, but differs 

 from that genus in the very different form of the discal cell. 

 Fi'om the Australian genus Metoponia, it is distinguished by 

 possessing three, instead of four, posterior veins. 



Cryptoberis hebescens, sp.nov. (Fig.l). 



Antennae, thorax, scutellum, and abdomen dark brown; legs 

 entirely yellow; wings tinged with brown. Length, (J, 7 '5 mm. 



Hab. — New South Wales (Sydney). 



Male. — Face brown, receding. Eyes bare, joined for a long 

 distance, the front being reduced to a very small patch at the 

 vertex, and a small, frontal triangle directly adjoining the 

 antennae. Antennae a little longer than the head, first joint 

 about twice the length of second, the third swollen and annu- 

 lated, and nearly twice the length of the first two joints together. 

 Thorax, scutellum, and abdomen dark brown, the whole covered 

 with short, white, depressed pubescence; sides of abdomen with 

 a little longer, white pubescence; genitalia prominent, yellow- 

 brown. Legs with femora and tibiae clear yellow; tarsi yellow, 

 a little browned towards the tips. Wings tinged with brown. 



This species is known only from a single specimen, which was 

 taken by Dr. Ferguson at Sydney, on November 12, 1914; it 

 occurred settled on the wall of a building. 



2. Metoponia Macq. 



Non-metallic flies; scutellum without spines Antennae in- 

 serted towards base of head; first joint a little elongated, second 

 short, third annulated with eight divisions. Wings with four, 

 posterior veins, all arising from the discal cell, first, second, and 

 fourth complete, third incomplete; cubital vein forked. 



This genus is unknown to me, the above characters being 

 taken from Macquart's description of the genus, and from his 

 figure and description of Xenomorpha australis, which Kertesz, 

 in his Catalogue, ascribes to this genus.
