274 Mr. G. Lewis on a new Genus of Coleoptera. 
critically, but I think I am right in saying that they cannot 
be separated generically. But, however this may be, the 
generic name I have employed will associate the species with 
Japan, as having been first characterized from thence, and 
the specific name will record the colour of the Japanese 
insect as well as the colour of the others, for all agree in this 
last particular. The genus is close to Nemozoma, Latreille 
(Nemosoma, Curtis), and to assist in its recognition I have 
given a simple outline of it. From its habits it is difficult to 
obtain, and I have not sacrificed an example for dissection. 
SHOGUNA, n. gen. 
Mouth-organs externally similar to those of Nemozoma; 
mandibles robust, dentate within, and bent inwards from their 
bases ; eyes small, almost circular in outline, partly visible 
from above; antenne inserted between the 
eyes and the bases of the mandibles; head, 
including the mandibles, measures the 
same as the thorax; epistoma obtusely 
subfurcate, nearly similar to that 
figured for Nipontus obtusiceps (Trans. 
Ent. Soc. Lond. 1885, p. 335). Antenne 
short, 11-jointed, joints 1-2 large, 3-8 
moniliform, 9-11 transverse to form a 
club, 11 fitting closely into 10, 9 freer. 
Thorax long, a little sinuate on the sides ; 
elytra one fourth longer than the thorax ; 
the sutural striz are entire and continued; 
round the apices and sides, the other 
striae are punctate-striate; pygidium 
slightly convex, wholly exposed, and some- 
what conical in outline when viewed from 
above; prosternum a little excavated between the coxe ; 
anterior portion of the mesosternum rather convex, smooth 
and shining; thighs robust; feet 5-jointed, basal joint but 
little visible. 
Shoguna rufo-testacea, n. sp. 
Angustata, rufo-testacea, nitida, leviter depressa, subparallela, 
supra minutissime strigosa et disperse elongato-punctata ; 
fronte utrinque oblique bisuleata; prothorace elongato, lateribus 
subsinuato ; elytris stria suturali integra, 1*-5™ punctato-striatis ; 
pygidio apice fulvo-hirto. 
Long. 43 mill.
