136 Mr. Walter F. H. Blandford on the 
This species is allied in its main features to the Platypi 
sulcati, with which I must associate it. It differs from 
the other described species in the strongly produced 
external apical angles of the elytra, which are not 
triquetrous as in the P. trispinati. The female 
shares with P. quadridentatus, Ol. (blanchardi, Chap.), 
the peculiarity of possessing two spines on the fourth 
abdominal segment, but is much larger and easily 
distinguished by the group of punctures on the thorax. 
The male is separable from that of P. modestus by its 
larger size, flat forehead, and oblong thorax; the elytra 
are quite glabrous before the apical extremity. 
Platypus severiivi, sp. n. 
Fem. Piceo-ferruginea, elytris postice infuscatis; fronte sub- 
concava, rugosa ; prothorace paullo longiore quam latiore, utrinque 
ad medium vitta obliqua subelevata, antice rarius irregulariter, 
postice crebrius punctato ; elytris ad apicem subdeclivibus et in 
processus divaricatos attenuatis, striato-punctatis, striis impressis, 
interstitiis subconvexis ad apicem pilosis, duobus primis per totum, 
ceteris ad basim subtiliter punctulatis, processibus desuper aspectis 
bidentatis. Long. 5—5:3 mm. 
Numerous examples of one sex only, taken from beech 
at Nikko, Chiuzenji, and Hakodate. 
Deep ferruginous brown, with elytra darker towards apex. 
Head with front subconcave, covered with close shallow rugose 
punctuation, rather smoother towards mouth, vertex rather abruptly 
separate from front, with three smooth vitte, interspaces coarsely 
punctured. Prothorax a little longer than broad, median sulcus 
fine but sharply marked, surface with very fine reticulation, and an 
indistinct oblique elevation at either side of anterior extremity 
of sulcus, punctures of anterior half scattered, and absent over 
middle line, of posterior half closer, shallow, and longitudinally 
oval. Elytra declivous towards apex and produced into two 
divergent processes, with subsulcate striz, which are wider and 
shallower towards apex, with the punctures fused ; interstices convex, 
finely reticulate and punctured at base, the first and second with a 
single row of punctures along inner border, all interstices flatter 
towards apex, inconspicuously tuberculate, and with serrate hairs ; 
apical processes declivous in the plane of the posterior termination, 
produced outwards to form an obtuse oval emargination at apex,
