given to its classification, that no importance can at present be attached to 
its consideration. The insects most likely ultimately to prove indigenous are 
the Diestotz, nine in number, and the extremely peculiar Oligote and Liophzene, 
eleven in number; the Oligote are very remarkable, and will no doubt ulti- 
mately form one or more distinct genera; O. clavicornis—which there is good 
reason tq treat as introduced—being the only form that will probably remain as 
a genuine Oligota. A good many of the other Staphylinide are cosmopolitan or 
widely distributed species; and others—such as Pachycorynus, Lispinodes, and 
Glyptoma—live under bark, and may probably have been immigrant in dead 
trees and logs; while as regards the Myllene and Trogophlzi the same remark 
may be made as that above recorded concerning the Bembidiini. 
The Trichopterygide have three peculiar species, each representing a distinct 
genus, and one of them peculiar. Mr. Matthews, the authority on this family, 
considers them highly interesting ; but as they are the most minute of all beetles, 
and our ignorance of the exotic forms is nearly absolute, no importance can at pre- 
sent be attached to this. 
The Histeridz have five genera and twelve species. None of the genera are 
peculiar, but nine of the species are not known elsewhere. It is significant that 
all these nine species are excessively minute forms, and most, if not all, occur in 
dead wood, so that it is probable they will be found elsewhere, and are in part 
immigrants in floating wood. 
The Nitidulidz have no less than forty-three species, a very large number for 
a small family, of which only about 1000 species are known from all parts of 
the world. Putting aside the three Carpophili, of which two are known to be 
introduced species, and the two Haptonci, one of which is also in this category, 
we have remaining thirty-eight species assigned to two genera. One of these two 
has five species, and is peculiar; the other—Brachypeplus—with no less than 
thirty-three species, is a widely-distributed genus ; but it should be remarked that 
Brachypeplus is not really at present a genus, but rather one of those composite 
magazines that abound in the present state of entomological knowledge—or rather 
ignorance, and that the Sandwich Island Brachypepli are themselves a very varied 
assemblage, and are not known to be at all closely allied to any of the forms found 
outside the islands. One of them, B. infimus, is very different from the others, 
and will, I believe, prove not endemic ; it lives under the bark of trees. The other 
Brachypepli have varied habits; many are found in flowers, some on or under bark 
of trees, and at exuding sap, and in the stems of ferns and other plants. The 
species of Gonioryctus—the peculiar genus—occur in flowers, and the stems of 
lilies and tree-ferns. 
The families Monotommide, Trogositide, and Rhyssodidz are each represented 
in the fauna we are considering by a single species of foreign origin. And though 
Colydidz have two species, one of them forming a peculiar genus, they probably
