entering second s.m. a considerable distance from its base. Antennse 

 entirely red. 



Habitat.— >^. Australia (Waterhouse; Nat. Mus. Vict. 149). 



Prosopis proxima Smith, var. a. 



A female from Purnong, S. Australia {S. W. Fulton; Nat. Mus. 

 Vict. 148) differs a little from the type in having the lateral face- 

 marks white without any trace of yellow, and the hind tibia? with a 

 dull white mark at base. The tubercles have the apical half white, 

 and there are two white marks on the prothorax above. The 

 axillae are red. 



Prosopis chrysognatha Cockerell. 



A male from Frankston, Victoria {T. Kershaw, Dec, 1902; Nat. 

 Mus. Vict. 160) seems to have the faintest possible bluish tint 

 on the abdomen, so faint, that it is difficult to be sure of it. If 

 run in my table among the species with metallic abdomen, it goes 

 straight to P. cognata Sm., which is evidently very closely allied. 

 Smith's cognata is from Champion Bay and Swan River, and has a 

 dark blue abdomen. The female described by Smith is to be con- 

 sidered the type. I have described the female of chrysognatha, 

 and it is not identical with cognata. 

 Prosopis alcyonea Erichson. 



Mordialloc (Nat. Mus. Vict. 186). 



Euprosopis elegans (Smith). 



Prosopis elegans Smith. From the National Museum of Victoria 

 come 5 9, 20^ (187, 152, 170, 251, 188, 151, 153); the localities are 

 Croydon {S. W. Fulton), S. Australia {W. Kershaw) and Fern Tree 

 Gully, Victoria (F. P. Spry). The males, without locality, collected 

 by C. F. Hill, have the postscutellum with only a small yellow 

 spot or patch. 

 Euprosopis nodosicornis n. sp. 



cf . Length 6 mm. or a little over, like E. elegans var. sydneyana 

 (Ckll.), with the postscutellum broadly yellow, but differing thus: 

 malar space longer; its length 270 microns; the bright ferruginous 

 flagellum with the last four joints thick, with large irregular tubercles 

 above, the three before these subtuberculate. The abdomen has 

 the first two segments and the sides of the third red, the first segment 

 with a diamond-shaped dusky discal mark. The sides of the meso- 

 thorax are broadly yellow. Stigma bright ferruginous. 



//a6^■ta^— Australia, no locality given (C. F. Hill; Vict. Nat. Mus. 

 155).
