Anatomy of the Male Genital Tube in Coleoptera. 639 
Phytophagoidea have no lateral lobes and are different 
from the other great groups. It is then only possible to 
derive them from some primitive Cucujoid form unknown 
to us. The term primitive (suppositive), as here used, 
may probably be interpreted as implying that if a con- 
nection of Phytophagoidea with our other series ever 
existed it was in the precoleopterous phylogeny. Though 
we have not discovered any important distinction between 
Rhynchophora and Phytophaga as regards the aedeagus, 
we may point out that our investigation of these two 
enormous complexes is very far from exhaustive as to this 
point. Also that this memoir is not concerned with other 
distinctions. 
We consider that the genital tube of the male is of 
great importance in the phylogeny of Coleoptera. And 
that its study makes it extremely difficult to accept less 
than eight primary divisions of the Order.

to what we have found in the Cerambycidae. It is therefore possible 
that even the aedeagus may ultimately show the Rhynchophora to 
have an origin distinct from the Cerambycidae.
