Hemar/rs. — Wliile possessing certain distiiicti\'e characters, N. 
ohricni seems, in respect to A’ery many of its features, to occupy a 
position intermediate betAveen A. spruceri and N. fuUoiii, the only 
leju'esentatiATS of tlie genus described, hitherto, as occurring in the 
eastern part of the Australian mainland. 
It is smaller and more slender even than the tiny A. fuJtoin 
and is peculiar in its eyeless condition and in the shortness of its 
first antennae. In the occurrence of olfactory cylinders (PI. IX., 
Pig. 1) on both antennae in the male, it resembles A. fultoni, 
altliough these organs are apparently much more numerous in the 
blind form. The existence of these structures in A. spenceri is not
