434 Mr. Blandford on the Scolyto-platypini, 
Mas. Fronte impressa pilis longis crispatis cireumdata, an- 
tennarum funiculo flexuoso, articulo primo transverso, sub- 
cylindrico, extus producto, ceteris transversis, clava subtriangulari 
acuminata, ciliata; prothorace antice in medio distincte impresso, 
interstitiis elytrorum in declivitatis versura carinatis. 
Fem. Antennarum clava ovali, subacuminata; interstitiis in 
versura non carinatis. 
Hab. Japan, Nikko. 
Cylindrical, convex, much smaller and narrower than S. tycon, 
shining, piceous black; elytra obscurely marked at base with two 
testaceous streaks. Head in male excised deeply, fundus finely 
reticulate, set over eyes with two dense fasciculi of long piceous 
hairs, which are curled into fundus, vertex punctured; in female, 
convex, punctured, finely pubescent. Antenne of male short, 
scape curved, clubbed, funiculus shorter than scape, flexible, its 
1st joint produced externally so as to be subcylindrical, but pointed 
at apex, and transverse, 2nd joint situated on distal side of Ist 
before apex, transverse, conical, succeeding joints transverse, 
little increasing in size, 4th and 6th slightly produced internally 
to bear a long seta; club subtriangular, acuminate, its outer edge 
feebly convex, its inner edge convex at base, forming a prominent 
rounded angle inside attachment of funiculus, and thence sub- 
concave to apex; extremity of the scape, the funiculus and club, 
hairy, the hairs of the latter of various lengths, and there is a 
fringe of about 16 long hairs on the inner edge and apex, as in S. 
tycon. Scape in the female less strongly clubbed; the 1st joint 
of the funiculus of the usual mushroom shape, and the rest as 
in the male; club oval, feebly acuminate and hairy, but without 
the long cilia and processes. Prothorax rather broader than 
long, its base slightly bisinuate, its basal angles acute; sides 
bisinuate, the anterior angles of the emargination being feebly 
marked, and broadly rounded at the apex in the female, more 
narrowly in the male, where there is a well-marked emargination. 
Surface finely reticulate, punctured and feebly pubescent; in the 
male there is a distinct longitudinal impression towards the 
anterior end of the median line, and two less marked ones on 
either side behind it. Elytra cylindrical, convex, double as long 
as thorax, and much wider at base, basal angles rectangular, 
sides parallel to near apex, then angled, the angulation being 
marked with a small tooth, and proceeding nearly straight to apex, 
which is obtuse; surface piceous brown, obscurely testaceous at 
shoulders, without trace of striz, with rather fine irregular punc- 
tures, some of which belong to the obliterated strizw, but are not
