the Lamellicorn Coleoptera of Japan. 383 
the sculpture above less coarse, but the most important dif- 
ference lies in the anterior portion of the mesosternum. The 
mesosternum anteriorly in S./aponicus is raised and the elevated 
part has a securiform gutline ; in S. nare this part is occupied 
by a circular impression more or less deep. The impression 
is usually well defined, but in one specimen out of twelve the 
impression is very shallow. ‘The thorax also is distinctly less 
transverse. 
Hab. Nara. On the 30th June, 1881, I found it abundantly 
under bark, and later in the year I obtained one specimen on 
Oiwake, a mountain on the Nakasendo, 
Oxyomus jugosus, sp.n. (Woodcut, fig. 6.) 
Oblongus, piceus, subnitidus; clypeo leviter emarginato, bitubercu- 
lato; thorace rugoso; elytris 8-costatis. 
L. 43 mill. 
Oblong, piceous, somewhat shining ; the head, clypeus 
very transverse, feebly but» widely emarginate, with a small 
tubercle on each side of the emargina- 
tion, surface uneven, with an ill-defined 
marginal impression and a feebly-raised 
disk in the middle, rugosely sculptured 
with punctures of various sizes, cheeks 
obtusely produced ; the thorax, anterior 
angles a little prominent, arched laterally, 
hind angles obsolete, sculpture rough and 
coarse and somewhat variolose, with a 
median impression before the scutellum ; 
the scutellum small and triangular; the 
elytra 8-costate, with the sutural edges 
markedly elevated and the epipleural 
margin finely carinate, the second and 
fourth coste are the most conspicuous, the second agreeing 
with the sutural costa, interstices not very distinctly 
sculptured, but the sculpture appears to consist of two 
longitudinal rows of short linear carine, humeral angle 
obtuse, elytra widest behind the posterior coxe and rather 
narrower at the base; the legs pitchy brown, anterior tibie 
carinate, with small transverse ridges on the outer side of the 
carina. 
Hab. Nagasaki. I took one specimen from under dead 
leaves near the Temple of Suwasama on the 23rd March, 
1881.
