Genus Brachymetopus McCoy, 1847. 



1. Brachymetopus strzeleckii McCoy, Ann. Mag. Nat. Hist., 

 XX., 1847, p.231, PI. xii., fig.l. 



Since this species was described by McCoy, no specimens of it, 

 or of any other member of the genus, appear to have been found 

 by collectors, though on the occasion of the first find at Dun- 

 vegan, N. S. Wales, quite a number seem to have been obtained. 



Genus P h i l l i p s i a Portlock, 1 843. 

 To Prof. McCoy we owe the first reference to the occurrence 

 of this genus in Australia {loc. cit. antea).
