ochreous. I think N. darwinorum is surely not more than 
a race of N. rubroviridis, but it is desirable to see the male 
of the latter. 
Nomia halictella Cockerell 
I 9 , Mossman, April 24 (Williams) ; 1 9, Cairns, May 
18 (Williams) . 
Nomia triangularis (Cockerell) 
II 9, 2 $, Halifax, May and June (Williams) ; 1 9, 
Babinda, April 18 (Williams). The male was described 
by me as N. pseudo ceratina. I described the female in 
1905 as Nomia halictella var. triangularis ; in addition to 
the differences cited, may be mentioned the darker tegulse 
and tarsi. I feel sure I now have the sexes correctly 
associated, and it is evident that the species is quite dis- 
tinct from N. halictella. 
Nomia australica Smith 
1 9, Melbourne (H. Edwards ) , has both clypeus and 
scape black. 1 $ , S. Australia (H. Edwards ), has scape 
clear red, black at end, but another with same data has 
the scape darker only faintly reddened. 3 $ , Melbourne 
(H. Edwards). 
Nomia frenchi Cockerell 
1 $, Melbourne (H. Edwards ); 2 $ , S. Australia (H. 
Edwards) . 
Nomia gilberti Cockerell 
1 9, Halifax, June or July (Williams). 
Nomia flavoviridis Cockerell 
1 2, Halifax, June; 40 <3,4 9, Babinda, April. All 
taken by Williams.
