1. Tetratemnizs scidpturatus, n. sp. 
T. parallelo-subfiTsiformis, niger, opacus, squamis cine- 
reo-fuscis lutosis plus minus obtectus ; capite rostroque 
(prjesertim in fronte foveolata) valcle inasqiialibus, grosse 
punctato-rngosis ; protliorace ovato, antice et postice trun- 
cato, mox pone apicem proflinde transversini constricto, 
foveam latam raediam fere efficiente, profunde, dense et 
grosse punctato; elytris valde profimde punctato-sulcatis, 
interstitiis alte costato-elevatis ; antennis pedibusque brevi- 
bus, crassis, rufescentioribus. Subtus (capite excepto) 
grosse sed parce punctatus.

Captus inter pinos flmgosque ad Hiogo, in ins. Nipon ; 
necnon prope Nagasaki, in ins. Kusliiu. 
Its dark hue, in conjunction with its opake and very 
deeply and coarsely sculptured surface, which is more or 
less sparingly besmeared with a kind of mud-Vike scaly 
deposit, and which tends to fill up the various inequalities 
and punctures, will serve additionally to distinguish the 
present insect ; though it is true that these particular 
characters exist likewise, to an almost eqiial extent, both 
in Pentacoptus and Coprodema. Nevertheless the struc- 
tural details which I have given above {par excellence of 
funicidus, eyes, elytra, and feet) will suffice at once to 
separate the T. sculpturatus from the members of those 
two genera. 
Judging from the comparatively large number of indi- 
viduals now before me, and which Mr. Lewis would ap- 
pear to have taken principally at Hiogo, in the island of 
Nipon, (" in old fungus-covered pines bordering a water- 
course"), I think it is very likely that the present Tetra- 
temnus is (if not common) at least widely spread ; for it is 
remarkable that I had already an example of it in my 
collection which I captured a few years ago (dead) out of 
a cup of tea, while in the island of Jersey, — a fact which 
would perhaps indicate that the species occurs equally in 
China, and that the example alluded to was accidentally 
imported (much after the fashion which we are accustomed 
dilated and bilobed. By-the-by, it is much to be regretted that the gene- 
rality of the continental Coleopterists still persist in characterising the 
tarsi of the Rhyncliopliora as tetramerous (which it is perfectly well 
known that they are not), and that too while the more correct term "pseu- 
dotetramerous" (proposed by Westwood upwards of thirty years ago, — 
mde Introd. p. 44) so exactly expresses their real structure.
