Abstract

This genus of stag-beetles is almost confined to Tasmania
(a single species being known from Victoria and
two from New Zealand), and in certain districts and
seasons almost every old log will be found to cover some
specimens of it. Almost all the species, as with most of
its sub-family, are very variable in size, in the shape of
the mandibles, and in the tibial dentition, so that it appears
as if there are many more species than really exist;
in consequence several forms of the same species have
been described under different names, and in all probability
mistakes in this respect will continue to be made,
except, possibly even, by those who have large series
under examination.
Except in the case of a few very distinct species, it
appears unsafe to identify single specimens of the genus
from the published figures and descriptions, or to describe
such specimens as new. Long series of many species
have convinced me that all, or most of them, have numerous
varieties, that without intermediate forms appear to
be distinct, but which by such intermediate forms can
quite readily be recognised as varieties only.
