New Species of Hawarvian Hymenoptera. 725 
This species is difficult to place. I think it belongs to 
the blackburni group, but it shows some affinities with 
the facilis group. In the table it would, if considered 
as having the process of the eighth ventral segment not 
dilated, be run down to anthracina, to which it is some- 
what allied ; if the process be considered dilated, of which 
there is slight indication, it would run to the heading of 
NV. assimulans, to which it is still more closely allied. 
The variation in the colour of the face in the ? is very 
remarkable and unusual.
