Rhynchophorous Coleoptera of Japan. 81 
striis vix impressis, interstitiis paullo subtilius uniseriatim vel 
irregulariter biseriatim punctatis, depressione apicali ad latera 
serie tuberculorum intus marginata. Long. 3°7 mm. 
Mas. Fronte impressa, longius pilosa ; abdominis segmento 20 
processu oblongo deplanato versus apicem incrassato et recurvato 
armato. 
Fem. Fronte subconvexa, parce pilosa; abdominis segmento 
20 tuberculo brevi conico armato. 
A pair taken at Kiga. 
Elongate and depressed, black with elytra piceous. Head with 
front strongly impressed in male and margined with long curled 
hairs, in female subconvex and strigose with scanty pubescence ; 
vertex strongly punctured in both sexes. Prothorax as long as 
broad, with sides nearly parallel behind middle, not strongly 
contracted in front, its punctuation rather strong, not close, weak 
over base only. Elytra as wide as prothorax and one-half longer, 
very slightly rounded at sides and narrowed behind, apex serrate 
and feebly emarginate ; surface with regular impressed rows of 
punctures, interstices narrow with subimpressed rows of rather 
weaker punctures, tending to become double on alternate inter- 
stices. Apical impression extending along sides of elytra and 
bordered within, above outer angles, by six or seven small 
tubercles. Underside black, abdomen reddish at sides, its first 
ventral segment prominently bordered, second in male with an 
oblong process, flattened vertically, its tip thickened and recurved 
upwards; in female with a short pointed tubercle, and rather 
dense pubescence. | 
Alhed to S. multistriatus, but differing in the structure 
of the abdomen, and the stronger punctuation, the thora- 
cic punctures being more scanty. The apical segments 
of the abdomen, nearly horizontal in the male example, 
are unfortunately missing in the female, which prevents 
comparison with another specimen from Nishi, which 
appears distinct, but cannot be separated by any definite 
characters ; it 1s rather larger, more convex, the thorax 
is more evidently narrowed in front, with the sides 
rounded behind ; the elytra are darker and broader; the 
abdomen is nearly vertical, armed as in the female type. 
This insect does not show any differences in sculpture 
that are of specific value, though the thorax is more 
finely punctured behind the middle. It must be sepa- 
rated, if at all, on further examples of both sexes.
