 1886, 1046.) 

 . Newcastle, New South Wales. 



18. Atteva Walk. 



The species of this genus, notwithstanding their conspicuous 

 colouring, are often very similar and difficult, and require close 

 attention. The colour and markings of the head and thorax, and 

 the modificMtions of the posterior tibi?e of the male, frequently 

 afford reliable distinctions. A. fulvlgnttala Z., is attributed 

 conjecturally to Australia, but in error; it is really West Indian.
