more opaque than in most, if not all, of its described congeners) is also a notable 
character. Its antenme are much like those of N. mcequalis, but are longer and a 
little more robust.

The large size and very broad build (taken together) of this species distinguish 
it readily from all its described congeners except 7najor^ Blackb., and 7-otundata^ 
Blackb. The former of these is rather close to it, but inter alia is a distinctly 
narrower insect with the lateral gutter of its prothorax (/>., the flat space imme¬ 
diately within the thickened margin) effaced considerably in front of the base, 
whereas in heroma the same runs on without any loss of distinctness quite to the 
basal margin (as in H. rotundata). From H. rotundata the present species differs 
inter alia 7ti2ilta by the presence of a tubercle on the front margin of its prosternum 
and the under surface of its head opaque and strongly punctured, whereas in 
rotimdata the corresponding surface is nitid and almost lievigate.
