Rhynchophorous Coleoptera of Japen. 79 
tured nearly as strongly as the striz in irregular series, which are 
not double, except at base ; somewhat rugose, and with slight 
longitudinal impressions. Punctures of the sides of the elytra 
much stronger than in S, eswriens. Abdomen not concave, margin 
of the Ist segment not prominent but sloped upwards, 3rd and 
4th unarmed, the 5th transversely impressed, Metasternum closely 
and rugosely punctured. 
Scolytus frontalis, sp. n. 
Oblongus, nitidus, niger, elytris rufo-brunneis, antennis pedi- 
busque ferrugineis ; capite (in maribus saltem) oblongo, fronte 
impressa, strigose aciculata, pilis longis crispatis circumdata ; 
prothorace haud transverso sat fortiter punctato, linea media 
laevi, punctis in disco paullo subtilioribus, magis diseretis ; elytris 
prothorace fere dimidio longioribus, lateribus subrotundatis, 
postice angustatis, subtiliter punctato-striatis, striis non impressis, 
interstitiis irregulariter vix subtilius seriato-punctatis, lo, 30, 50 
biseriatim, subrugosis ; abdomine subconvexo, margine segmenti 
Imi haud prominulo, cum ceteris mutico. Long. 3°6—4°3 mm. 
Three examples taken at Fukushima. 
Resembling S. prun?, Ratz., in appearance, but with the pro. 
thorax more strongly punctured, and the elytral striz: much less 
regular. Black with anterior margin of thorax and elytra red- 
brown. Head (in the male, to which sex the specimens belong) 
oblong, produced in front, and impressed, with long aciculate 
scratches from mouth to vertex, margined with long curled yellow 
hairs, median line finely carinate, epistoma subcircularly emargi- 
nate. Prothorax about as long as broad with moderately strong 
oval punctures, closer and deeper at sides. Elytra as wide in 
middle as prothorax, and nearly one-half longer, narrowed behind, 
rather abruptly rounded at apex and feebly emarginate at suture ; 
surface little depressed round scutellum, with fine irregular rows 
of punctures, interstices narrow and flat, with slight transverse or 
oblique wrinkles, their punctures little finer than and not readily 
distinguishable from those of striz, forming an irregular double 
row on Ist, 3rd and 5th interstices, and a single row on remainder, 
except at base where they are irregular. Underside piceous, lighter 
at sides, thinly pubescent ; abdominal segments simple, margin of 
1st not prominent. ; 
Scolytus aratus, sp. n.
