14. P. 2m.nctata, Br. (PI. VII, fig. 11, PI VIII, figs. 11 a, 17h.) 



Polyzostcria punctata, Brunner von Wattenwyl, Nouv. 

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



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

 but imnctata 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.) 



Poli/sosto'ia. variolosa, Bolivar, Ann. Soc. ent. France 

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



In the female the supra-anal lamina is produced, 

 cucullate, posteriorly widely emarginate, with acute angles, 

 lateral margins entire. 



New Caledonia, Noumea (Bolivar); Ile des Pins 

 (Oxford Mus.). 



16. P. scabra, Br. 



Polyzosteria scahra, Brunner von Wattenwyl, Nouv. 



Syst. Blatt., p. 213 (1865). 

 Polyzostcria tarsalis, Walker, Cat. Blatt. Brit. Mus., p. 



162 (1868). 



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

 scabra). Port Hacking (TV. W. Froggatt), (Oxford Mus.); 

 " Australia " (British Mus., type of tarsalis). 



17. P. scabrella, Tepp. 



Platyzostcria scabrella, Tepper, Tr. R. 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. Froggatt), 

 (Oxford Mus.).
