oblique, not sharply bent near the cubitus, longer than the 

 second. Second abscissa of the radius about twice as long as 

 the first, the two combined shorter than the third. First 

 i-ecurrent nervvire received distinctly beyond the middle of the 

 second cubital cell, second beyond one-third from the base of 

 the third cubital cell. Hind wing as in A. austi-alasice. Apical 

 joint of maxillary palpi as in A. atosiralasice, not filiform and 

 scarcely longer than the penultimate joint. 



Black ; the legs ferruginous. Wings hyaline, nervures 

 fuscous. 



Length 12-15 mm.

(S . Clypeus truncate at the apex ; antennae nearly as long as 

 the thorax and median segment combined. Pronotum short, 

 scarcely more than half as long as the scutellum, very slightly 

 narrowed anteriorly. First ..dorsal .segment longer than the apical 

 breadth ; seventh dorsal segment broadly rounded at the apex. 

 Hind tibi?e rather feebly serrate ; hind femora without a lobe at 

 the apex beneath. Second abscissa of the radius longer than the 

 first, the two combined much shorter than the third ; first 

 transverse cubital nervure oblique, sharply bent close to the 

 cubitus ; first recurrent nervure received at the middle of the 

 second cubital cell, second at two-fifths from the base of the third 

 cubital cell. The distance between the cubitus of the hind wing 

 and the transverse median nervure is greater than half the length 

 of that nervure. 



Black ; the fore tibiae ferruginous within ; calcaria whitish. 

 Wings hyaline, nerAmres fuscous. 



Length 9-12 mm. 



Hah. Yictoria and South Australia. 



Diff"ers from vatnpes in the absence of a, carina on the scutellum, 

 in the colour of the legs, and the more distinct serration of the 

 hind tibiae.

cJ . Antennae stouter than in other Australian species ; pro- 

 notum very slightly narrowed anteriorly, shorter than the 

 scutellum. Head and thorax very closely and finely punctured, 

 median segment transversely rugulose, short and not as strongly 

 convex as in other species. First dorsal segment very little 

 longer than the apical breadth ; seventh dorsal segment narrowly
