‘ Challenger’ Coleoptera. 277 
Quedius fulgidus, Fabr. 
Hab. Nightingale Island. 
Numerous specimens agreeing perfectly with Huropean 
examples. This species has occurred in very remote parts of 
the world. 
PALACHTHUS, n. gen. 
General characters of Hrirrhinus, but with the third joint 
of the tarsi scarcely broader than the preceding, &c. Rostrum 
about the length of the thorax, rather stout, slightly curved, a 
little narrowed to the apex; the antennal scrobe commencing 
near the apex, extending to the eye, deep, bounded above by 
a ridge. Antenne long, moderately slender; scape a little 
enlarged towards the apex; first joint of the funiculus about 
twice as long as broad; the second joint a little longer, the 
third to seventh subglobose ; club ovate, the first joint smooth 
and shining. LKyes not large, not prominent, transversely 
ovate, a little simuate anteriorly for the antennal scrobe, 
Thorax a little longer than broad, subparallel, a little nar- 
rowed at the base, rather more so in front, moderately flat- 
tened, with surface even; anterior margin slightly sinuate 
behind the eye; the anterior margin of the prosternum emar- 
ginate. Scutellum very small, elongate. Llytra at the base 
a little broader than the thorax, narrowed at the apex, arched 
posteriorly, the sides nearly perpendicularly ; punctate-striate, 
the surface even, setose. Legs moderate. Anterior cox 
very prominent, contiguous; intermediate coxe globular, 
prominent, separated by a narrow process; posterior cox 
transversely ovate. Femora moderately enlarged in the 
middle. ‘Tibi bisinuate on the inner side; the outer apical 
angle obliquely rounded ; the mucro distinct, especially to the 
anterior tibia. ‘T'arsi moderately long and narrow, densely 
pilose below, the first, second, and third joints subequal in 
length ; the third scarcely wider than the preceding, scarcely 
bilobed, with only a narrow incision at the apex visible from 
below ; claws free. Metasternum very short, impressed pos- 
teriorly ; parapleura extremely narrow. Abdomen with the 
divisions between the basal segments effaced (except close to 
the side), these segments concave; the intermediate segments 
very short, separated by very deep incisions. 
The general form of the larger of the two species for which 
I propose this genus is somewhat that of Hrirrhinus macu- 
latus, but with a longer thorax, not narrowed at its base. 
The smaller species is rather more depressed.
