It is not clear whether the appression of the pubescence 

 of certain parts is natural or otherwise, the specimen 

 appearing to be in a rather dirty condition. 



The type is in the British Museum.

Nomadidse. 



NoMADA. 



This genus is only known in Australia from Queensland, 

 Avhere but a single species, here described, has so far been 

 discovered. Considering the abundance of Andrenid Ijces of 

 tiie genera Halictm and Parasphecodes, one might expect 

 many species of Nomada, parasitic on these ; but such is 

 not the case, and it is probable that this genus is a com- 

 paratively recent arrival. It is a small and obscure species, 

 and apparently not very common. Turner has taken it at 

 Mackay and Cairns, and 1 have received the female from 

 Dodd from the latter district.
