500 CUCUJIDE. 
in making any radical alterations. I have, however, intimated in the following pages 
that the Rhizophagine should be brought into the Cucujide ; that Hemipeplus should 
be removed from the family to the Heteromerous series ; and I may here add that several 
genera, that will be placed in our pages in Monotomide, in conformity with the views 
of Leconte and Horn, should also be brought into the Cucujide, to be placed near 
Rhizophagine. 
The characters made use of for defining the subfamilies of Cucujide have not been 
happily selected by Erichson and his successors, and I have been compelled to establish 
a new subfamily, Ancistriine. 
Subfam. PASSANDRINA. 
In this subfamily the anterior coxal cavities are open; the basal joint of the feet 
is extremely short, so that the tarsi appear only 4-jointed ; and the sides of the under 
surface of the head are prolonged so as to cover the maxille. 
The North-American genus Scalidia is unknown to me*; it will probably prove 
to be a member of the Ancistriine, and not of Passandrine, where it is placed by 
Leconte and Horn. 
PASSANDRA. 
Passandra, Dalman, in Schénh. Syn. Ins., App. p. 146 (1817). 
This is a genus of some eight or ten species, and is of very wide distribution, though 
limited to the warmer regions of the world.

This appears to be a rare insect, most of the localities having yielded only one or two 
examples. Hége, however, procured a small series at Bobo, and this suggests that 
the considerable variation the species exhibits in size and colour may be to some 
extent geographical. 
CATOGENUS. 
Catogenus, Westwood, Zool. Journ. v. p. 221 (1835). 
This genus comprises about twelve species, and is confined to the New World, with 
the exception of one representative found in S. Africa; this I have not seen. 
* Unless, as I have suggested in the following pages, when dealing with Syssitos, it should prove to be 
that genus.
