NOTONECTA Linnaeus. 



Notonecta Linn., Syst. Nat., ed. x, 1758, p. 439 ; Fieb. Khynchotogr., 1851, p. 48 ; 



P'lor., Rhynch. Livl, i, I860, p. 766; Sannd., Hem. Heteropt. Brit. Is., 1892, 



p. 329 ; Kirk., Trans. Ent. Soc, 1897, p. 397. 



Type, N. glauca Linnaeus. 



Only one Australian species may be definitely assigned to this almost 

 universally distributed genus; no Notoncctae occurred amongst the considerable 

 amount of material examined for the preparation of this paper. 



NOTONECTA HANDLIRSCHI Kirkaldy. 



Notonecta handlirschi Kirk., loc. eit., p. 408. 



Kirkaldy remarks : "Something like N. nmericana Fain-., but with the pattern 

 and colour very obscure. I have very great pleasure in dedicating this species, 

 the first true Notonecta from Australia, to Dr. Handlirsch, of the Vienna 

 Museum." 



Loc. "Australia." Type in Vienna Museum. 



? NOTONECTA AUSTRALIS Olivier. 



Notonecta oustralis Oliv., Encycl. Method., viii, 1811, p. 389. 

 Notonecta ( ? Anisops) anstralifi Kirk., Trans. Ent. Soc, 1897, p. 426. 



Kirkaldy, in his "Revision of the Notonectidae. Part T." was unable to 

 trace this species, which he suggests may be an Anisops. Olivier 's short descrip- 

 tion is practically confined to colour; in Enithares hergrothi the colouring is 

 quite similar.
