Runs in the table to no group there given, but requires a new 

 subdivision, of species with abdomen largely red, and red on scutel- 

 lum and postscutellum. 



Habitat. — Ararat, Victoria (Rollc). 2 males. Berlin Museum. 



Nomia subaustralica, new species. 



Female. — Length about 1 1 mm. ; black, the abdomen somewhat metallic, 

 with broad pale ochreous hair-bands. This species had been labelled A^. 

 australica by a distinguished authority, and it does indeed resemble that in- 

 sect, differing as follows : rather smaller ; face rather narrower, and covered 

 with appressed or subappressed pale (dull whitish) hairs ; scape red in front, 

 base of flagellum (about two joints) lively red above and below, rest of 

 flagellum black, except a reddish stain at apex ; tegulse pale testaceous, the 

 margins whitish ; larger punctures of mesothorax even more sparse ; meso- 

 thorax densely covered in front, behind and more or less at sides with easily 

 deciduous moss-like light fulvous hair, and with no erect black hair ; post- 

 scutellum covered with fulvous hair, and scutellum ornamented like the meso- 

 thorax; tubercles with pale fulvous hair; pleura with quite dense dull white 

 hair; area of metathorax narrower (shorter anteroposteriorly), hardly sculp- 

 tured ; stigma shorter ; first r. n. meeting second t. c. ; hair on inner side of 

 hind basitarsus white or nearly ; abdomen black, the first two segments strongly 

 tinted with green (or purplish on second) ; bands on first four segments pale 

 ochreous, broad and entire ; disc of first segment, before the depression, 

 smooth and shining, with strong scattered punctures ; second and third seg- 

 ments similar, with the addition of numerous minute punctures, which on the 

 second are massed anteriorly. 



Habitat. — Finke River, Hermannsburg, S. Australia {v. Leon- 

 Jiardi) ; Tennant's Creek, S. Australia (Rolle). The latter is the 

 type locality. Two specimens of A^. australica Smith in the collection 

 are from Melbourne, Victoria (Rolle). 



JNomia nana Smith (ruficornis Smith). 



Adelaide (Schombiirgk) . This is the type locality. 



Nomia flavoviiidis adelaidella, new subspecies. 



Male. — Like A'', flavoviridis CklL, but a little smaller ; flagellum bright 

 ferruginous above and beneath ; nervures and stigma clear ferruginous. Ab- 

 domen greener than head or thorax. 



Female. — Antenna dark, flagellum ferruginous beneath ; nervures and stigma 

 as in male. Abdomen very green. Two other females with the same data 

 have dark nervures like true flavoviridis. 



Habitat. — Adelaide {Schombiirgk).
