Geodephagous Coleoptera of Japan. 257 
on the front, and the epistome is very broadly sinnated, 
ahnost straight. The eyes are not so prominent as in R. 
JE(jyj)t'iacus ; the mandibles are very broad and obtuse. 
The labrum is short and deeply notched. The thorax is 
nearly square, very little rounded anteriorly, narrowed in 
front, and slightly narrowed, with a distinct sinuation, 
behind ; but the hind angles are very obtuse. The basal 
foveiB are deep and broad. There are faint traces of punc- 
tures in the bottom of the deeply-sunk strife of the elytra. 
The Chinese specimen is less convex and less deeply 
striated, but offers no well-marked specific difference. 
The species seems to connect Eccoptogenius (Chaud.) 
with Remhus ; its antenna3 and legs being robust, and the 
anterior tibi^ rather more dilated at the apex, with a 
comb-like row of short spines on the outer edge. This 
latter character is seen also, in a somewhat minor degree, 
in the more robust species oi Rembus. 
Badister pictus, n. sp. 
B. hipustulato similis, at magis elongatus. Angustatus, 
niger, nitidus ; thorace, pedibus, antennarum scapo et palpis 
(articulis ultimis exceptis) testaceo-rufis ; elytris testaceo- 
rufis iridescentibus, maculis utrinque late separatis duabus ; 
antennarum articulis 7 — 11 fulvis.

The head is minutely shagreened and small in both 
sexes. The thorax is much longer than in B. bipustula- 
tus, shagreened and subopake ; gradually narrowed behind, 
with rounded hind angles. The elytra are sharply and 
finely striated ; both the black spots are lateral, the one in 
the middle, extending from the 2nd to the 8th stria, and the 
other subtriangular, at the outer angle of the apex, reach- 
ing the margin, except for the red, reflexed edge of the 
elytron. The 1st antennal joint is red ; the 2nd red, with 
a black spot ; the 3rd — 6tli black, and 7th — 11th tawny- 
red. Beneath, the prothorax and the mesothorax are red ; 
the rest black.
