body together) it will then, I think, prove, as intimated above, to 
be synonymous with ZL. quadridens, Hope, a specimen of the 
latter in my own collection corresponding so exactly with both 
the description and figure of Swederus that it makes me very 
much disposed to unite them together,

In the female, which sex alone was known to Mr. Hope, the 
anterior tibize are curved exteriorly, whence the specific name ; 
those of the male however are but very slightly curved. The small 
lateral spine existing on the prothorax of the male is often very 
indistinct in the female; the rudiment however of it is mostly to 
be traced. ‘The peculiar formation of the mandibles in the 
present insect, and its small size, render it one of the most con- 
spicuous species of the genus in which, for the present, lL have 
placed it.

The unique insect on which this species is here proposed is 
a female of a glossy black colour, distinguished from the majority 
of the females of the genus Dorcus by the oblique emargination of
