Records of Decs. 145 



Prosopis nubilosella mediosticla, subsp. ii. 



? . — Larger, length about 8 mm. 



AVitigs strongly infiisoated ; second s.m. not especially 

 long ; cljpcns uliolly black ; a triangular creamy-white mark 

 on upper part of supraclypeal area ; inconspicuous linear 

 marks at sides of front as iu nuhiloseUa ; tubercles broadly, 

 mesotborax and seutellum bright orange, the surface of 

 mesothorax and seutellum dull. Abdomen pure black, 

 finely but distinctly punctured. Head short and broad 

 compared with nubilosa and its immediate allies. 



Hub. Botanv, New South Wales, Nov. 10, 1891 (Froggatt, 



This is perhaps a distinct species, but it is in any event 

 very close to F. nubilosella. The legs carry thi'ee asclepiad 

 pollea-masses. 



Prosopis quadriceps^ Smith, var. a. 



? . — Large (about 8 mm. long). 



Legs all dark except the broadly yellow base of bind tibiae ; 

 lateral face-marks lobed above, the whole shape much like 

 that of a snail crawling, with obtuse foot and no tentacles. 



Hub. Kenthurst, New South Wales, Oct. 9, 1903 

 {Froggatt, 27). 



I do not give this a special namCj as it is probably no 

 more than an individual variation. 



Prosopis chrysognatha, Cockerell. 



Described from ^Melbourne. A male {Froggatt, 30) is 

 labelled '^ A. decur., Nest,'' March 10, 1893. It differs 

 from the type in having the first r. n. meeting first t.-c. 

 We are doubtless to understand that it nests in Acacia 

 decurrens. 



Prosopis aJcyonea, Erichs. 



Both sexes from National Park, New South Wales, 

 Dec. 10, 1909 (T. McC. ; sent by Froggatt). 



Prosopis impress if 7'Ofis, Smith. 



Described from ''New Holland." A male before me is 

 from Kenthurst, New South Wales, October 1903 {Froggatt, 

 32). The second to fourth ventral segments of abdomen 

 have a rather inconspicuous tubercle on each side. The 

 scape is extremely thick.
