1. U: sulverrucosa, White. 



Blattct suhverrucosa, White [in] Grey, Journ. Exped. 



Australia, ii, p. 467 (1841). 

 Polyzosteria reflcxa, Brunner von Wattenwyl, Nouv. 



Syst. Blatt., p. 208 (1865). 

 Polyzosteria femoralis, Walker, Cat. Blatt. Brit. Mus., 



p. 156 (1868). 

 Polyzosteria figurcda, Walker, op. cit., p. 157 (1868). 



A common and well-known species ; jigurata is merely 

 a larval form. 



South and Western Australia. 



2. E. sulrejiexa, Tepp. 



Polyzosteria suhrcflexa, Tepper, Tr. R. Soc. S. Australia, 

 xix, p. 158 (1895). 



The diagnosis does not show how this species differs 

 from the preceding. 



South Australia, Ooldea (Adelaide Mus., type). 



3. PJ. nolilis, Br. 



Polyzosteria nohilis, Brunner von Wattenwyl, Nouv. 

 Syst. Blatt., p. 209 (1865). 



Polyzosteria suhnohilis, Tepper, Tr. R. Soc. S. Aus- 

 tralia, xvii, p. 81 (1893). 



Tepper failed to recognise Brunner's species, his descrip- 

 tion of suinohilis corresponds exactly with nohilis; the 

 smooth spaces that he describes on the abdominal tergites 

 are hidden in contracted examples. 



South Australia, Adelaide, Kangaroo Is.; West 

 Australia, Swan River (Vienna Mus., type; British 

 Mus. ; Oxford Mus. ; Adelaide Mus., type of sicbnobilis).
