The general colour varies from pitchy-brown to dullish eneous and 
violaceous-coppery ; the external and deflexed margins of the elytra, 
and often also the posterior angles and margin of the thorax, being 
reddish. The form of the thorax is not at all cordate, as in O. elivi- 
noides, but is quadrate, a little rounded on the sides anteriorly, and 
moderately and gradually sinuate-angustate posteriorly. 
Specimens of O. Maceyi have been submitted to M. Putzeys, who 
informs me that it is distinct from all other species. 
1 received large numbers of this insect, through the kindness of 
Mr. Coleman, from Capt. Macey, who obtained them in the Falkland 
Islands, together with a few specimens of Trechus antarcticus, and 
a large series of Antarctica blanda and malachitica. 
OoPTERUS LEHVICOLLIS, un. sp.—O. clivinoide latior, multo minus 
convexo, thorace nequaquam cordato; nigro-subeneus, labro,palpis, antennis, 
pedibus elytrorumque margine deflexo rufo-piceis ; capite suleis frontalibus 
vie impressis, brevibus ; thorace quadrato, lateribus medio rotundatis, an- 
tice et postice (haud sinuatim) leviter angustato, angulis posticis subrectis, 
supra, levi basi utrinque bifoveolato, foveis haud distincte punctatis; elytris 
ellipticis, punctato-striatis, interstitio 3 quadripunctato.

New Zealand, Very closely allied to the Falkland Island species 
above described ; differing chiefly in the thorax being more rounded in 
the middle, and in the palpi and antennz being entirely of a reddish 
colour. The impunctate fovez of the thorax and distinctly impressed 
elytral striz distinguish it from O. rotundicollis, White. 
The genus Oopterus is a purely Antarctic form, and the species, 
closely allied to each other, are found in New Zealand, the Auckland 
Islands, Soledad Island, and the Falkland Islands. This distribution, 
over lands separated by such wide expanses of ocean, is the more re- 
markable as the species are apterous, as well as purely terrestrial in 
their habits. The genus belongs to the Drechini group. The sutural 
stria is continued round the apical margin, but recurves only near the 
lateral margin, where it is separated from the sulcate sub-marginal stria 
by a raised line.

Note on Quedius brevicornis, Thoms., a species new to the British Fauna.—I 
have recently taken in Studley Park four specimens of a Quedius, which Mr. Rye 
thinks should be referred to @. brevicornis, Thoms., already erroneously recorded 
as British, the insects on the authority of which it was added to our list being 
afterwards considered to be @. punceticollis, Th. (for notes on this and allied species
