Lamellicorn Coleoptera of Japan. 99 
brown tubercles. Thorax convex, clothed with dirty-white 
tomentum, thickly punctured, broadly lobed over the head, 
anterior angles obtuse, the sides slightly rounded in front 
and then gently emarginate before a lateral projection, 
which has its apex rounded ; the posterior angles obsolete ; 
the posterior margin gently flexuous, with a projecting lobe 
over the scutellum. The thorax above is furnished with 
a triangular raised portion (divided in the middle by a 
furrow), the base of which forms the anterior margin of 
the thorax, and the apex is directed backwards; on each 
side it is emarginate in the middle. There is, moreover, 
on each side, at the posterior angle, a kidney-shaped 
tubercle, and two others placed on the hind margin, one 
on each side, near the scutellum. The scutellum is trefoil- 
shaped. The elytra are ashy-grey, about 2? times as long 
as the thorax, rather broader posteriorly, with the sides 
straight in the middle; they are obscurely punctured in 
lines, with about eight rows of small, oblong, only slightly- 
raised tubercles; the tubercles in the second row are dis- 
tinctly larger and are black at the base. Here and there 
on the elytra are shining black spots.
