1910.] FOSSORIAL WASPS OF AUSTRALIA. 307 



at one quarter from the base of the second cubital cell ; second 

 recurrent received at one-fifth from the base of the third cubital 

 cell. 



Black ; the apex of the scape and the flagellum beneath f usco- 

 ferruginous ; the basal half of the mandibles, tegulse, tibia?, tarsi, 

 the apex of the femora and the whole of the posterior femora 

 ferruginous. Wings hyaline, faintly tinged with yellowish 

 brown, nervures fuscous, stigma ferruginous. A dull ferruginous 

 spot on the outer margin of the eyes, close to the summit. 



The posterior femora are produced below near the apex into a 

 broadly rounded flattened projection, rather more strongly deve- 

 loped than in most species of the genus. 



Length 13 mm. 



Hah. The locality on the label is Endeavour River, Queens- 

 land, but as other species received from the same source and 

 bearing the same locality are undoubtedly Victorian, I consider 

 that this also is almost certainly from Victoria. 



Most nearly allied to A. cognata Sm. from the Swan River, bub 

 differs in neuration and in the sparser sculpture of the abdomen. 



Type in Berlin Museum. 



Anthobosca nubilipennis, sp. n. 



2 . Olypeus coarsely but sparsely punctured, broadly rounded at 

 the apex. Scape smooth above, very sparsely punctured beneath 

 and with a few short hairs. Head sparsely but deeply punctured, 

 the front rugose in the middle, the vertex behind the ocelli 

 almost smooth. Eyes very broadly and feebly emarginate on the 

 inner margin. Pronotum and scutellum coarsely but not closely 

 punctured, the pronotum almost as wide as the head ; mesonotum 

 as long as the pronotum, smooth, with a few scattered punctures 

 on the sides and near the posterior margin ; propleura? punctured 

 above and in front, obliquely striated below and behind ; meso- 

 pleurse coarsely but not very closely punctured ; the sides of the 

 median segment obliquely striated. Scutellum very broadly 

 rounded a,t the apex. Median segment finely rugose, subtuber- 

 culate in the middle at the base, shorter than the scutellum, 

 abruptly and almost vertically truncate posterioidy, the surface of 

 the truncation shining and almost smooth. Abdomen rather 

 sparsely punctured, more closely and finely at the base of the 

 third and fourth segments, the basal segment almost smooth. 

 Sixth dorsal segment coarsely longitudinally striated from the 

 base to beyond the middle, the apex rounded and very delicately 

 rugulose ; the ventral plate subtriangular, very narrowly rounded 

 at the apex. Wings rather short, the second abscissa of the 

 radius half as long again as the first, the third nearly half as long 

 again as the second. Radial cell very narrowly rounded at the 

 apex, almost pointed, separated from thecosta at the apex ; stigma 

 small and narrow. First recurrent nervure received by the 

 second cubital cell at two-thirds from the base, second received 

 by the third cubital cell just before one quarter from the base.
