Polyzosteria punctata, Brunner von Wattenwy], Nouv. 

 Syst. Blatt., p. 211 (1865). 



The nearest ally of this species is perhaps aierrima, Er., 

 but punctata is narrower. The seriately arranged shallow 

 punctures on the thoracic tergites are distinctive ; the 

 supra-anal lamina is scabrous and the lateral margins of 

 the 7th abdominal tergite are slightly serrate. 



New South Wales, Sydney (Vienna Mus., type). 



15. P. variolosa, Bol. (PI. VII, fig. 13.) 



Pol i/zosteria variolosa, Bolivar, Ann. Soc. ent. France 

 (6) ii, p. 460 (1882). 



In the female the supra-anal lamina is produced, 

 cucullate, posteriorly widely emarginate, with acute angles, 

 lateral margins entire.

 scahra). Port Hacking {W. W. Froggatt), (Oxford Mus.);

17. P. scahrella, Tepp. 



Platyzosteria scahrella, Tepper, Tr. B. Soc. S. Australia, 

 xvii, p. 88 (1893). 

 This should be readily recognisable from the descrip- 

 tion; it can be distinguished from the preceding species 

 by its smaller size, the rufous antennae and by the wide 

 emargination of the sub-genital lamina of the $. The 

 supra-anal lamina of the $ is subquadrate with rounded 

 angles, there are three short teeth on either side near the 

 apex. 



South Australia, various localities (Adelaide Mus., 

 types); New South Wales, Gunnedah (IF. W.Frogrjatt), 

 (Oxford Mus.).
