margins are minutely serrate ; in the female the lamina is 

 constructed as in polyzona $. The species varies in 

 colour ; in some examples the pale border is broad and the 

 legs are testaceous, in others the pale border is narrow and 

 the legs are castaneous.

4. A. lindsayi, Tepp, 



Anamesia lindsayi, Tepper, t. c, p. 71 (1893). 

 Known to me only from the description. 

 West Australia, Fraser range (Adelaide Mus., type). 



5. A. loallccri, sp. n. 



^. Unicolorous testaceous. Head, dorsal surface and abdominal 

 sternites finely punctate. Eyes very wide apart, equally distant with 

 the antennal sockets. Supra-anal lamina quadrate, margins entire, 

 apex truncate, non-emarginate, fimbriate, surpassed by the sub- 

 genital lamina which is quadrate, produced, posteriorly very slightly 

 emarginate, with styles from near the base. Cerci short, blunt, 

 exceeding both laminae. 



Length 2r2 mm.; pronotum 7'1 mm. x 11 mm. 



New S. Wales, Sydney (Oxford Mus., type). 



This is a somewhat remarkable species, superficially 

 resembling very closely Zonio'ploca fallidci mihi, but dis- 

 tinguished by the uon-incrassated margins of the pronotum, 

 non-produced angles of the abdominal tergites, absence of 

 granules on the dorsal surface and by the unicolorous legs. 

 The distance of the eyes apart shows that much reliance 

 cannot be placed on this character for purposes of discrim- 

 inating between Old and New World Blattinae. I have 

 much pleasure in naming this interesting species after 

 my friend and colleague, Commander J. J. Walker, R.N., 

 who presented the unique example to the Oxford Museum.
