Rhynchophorous Coleoptera of Japan. 137 
their upper border curved and continuous with second interstice, 
extremity two-spined when seen from above, inner spine longer and 
truncate. Last abdominal segment subconvex, rugosely punctured. 
The species belongs to the Platypi oxyuri, and may be 
distinguished from the Pyrenean P. orywrus, Dup., by 
the thoracic sculpture, and by the processes of the elytra 
being two-spined when seen from above instead of from 
the side, as in the latter species. From P. solidus, 
Walk., the divergence of these processes will at once 
separate it, as will its larger size, and the convex 
interstices which, except the first two, are impunctate 
after the base.

Long. 3°7 mm. 
Sixteen examples of one sex only, taken at various 
places, Miyanoshita, Oshima, Kiushiu (Higo, Yuyama, 
etc.). 
Slender, reddish testaceous, elytra with apex darker. Head with 
front concave, anteriorly dull, with a deep longitudinal impressed 
line in middle, above it, with rather strong scattered punctures, 
upper part forming an obtuse angle with vertex, which has only 
the median elevated line present, narrow and infuscate. Prothorax 
one half longer than broad, the sulcus fine, with a narrow group 
of punctures on either side, closer anteriorly, remainder of 
surface irregularly punctured, the punctures more evident towards 
the base, anterior and posterior borders with fine transverse 
reticulation. Elytra finely punctured in lines, sutural stria 
impressed throughout, remainder at base only ; interstices with a 
few fine punctures, 1st, 3rd, and 5th elevated at base, the former 
impressed with a fine line beginning behind base, 2nd and 4th with 
base evidently punctured. Apex of elytra with an oblique terminal 
impressed surface, its margin elevated and slightly everted, curving
