114 Mr. Walter F. H. Blandford on the 
nearly straight, slightly divergent from base to near apex, which 
is strongly rounded, surface somewhat depressed, declivous for 
anterior third, its junction with the posterior cylindrical part 
marked by a fine elevation at the apex of an indistinct raised line 
reaching nearly to base ; finely asperate in concentric lines before 
elevation, with sparse short hairs, basal half shining, feebly 
punctured, with a row of more distinct punctures on either side 
of central line. Scutellum rounded, piceous, shining. Elytra as 
wide as base of prothorax and half as long again, basal angles 
rounded rectangular, humeral callosities distinct, sides subparallel, 
apex circularly rounded and acutely margined below by the 7th 
interstice ; surface subdepressed, very obliquely declivous at apex, 
punctured in rows, interstices flat witha single row of very fine 
sparse punctures ; declivity with 1st and 3rd interstices elevated, 
finely tuberculate and setose. Underside and legs testaceous, the 
former punctured at sides and at apex of abdomen. 
Readily distinguished by its small size, narrow form, 
fine sculpture and colour. 
Xyleborus attenuatus, sp. n. 
Fem. Elongata cylindrica, a prothorace medio posterius sub- 
angustata, subnitida, pilis erectis brevibus pubescens, picea ; 
prothorace oblongo, in medio transverse elevato, postice sublaevi, 
punctis minutis notato ; elytris ad amussim punctato-striatis, iuter- 
stitiis uniseriatim punctatis, apice subopaco, oblique rotundato, 
sutura elevata, interstitiis lo, 30, et 40 tuberculatis, 20 inermi., 
Long. 2.6. mm. 
One example, Nikko. 
Very closely allied to X. saxeseni, Ratz., like the 
following species, but in my opinion distinct from either. 
From X. saweseni it differs as foilows: 
The body is more elongate and evidently narrowed, especially 
towards the apex of the elytra, and is furnished throughout, 
including the posterior half of the prothorax, with short upstanding 
hairs ; thoracic tubercle more elevated, the surface behind less 
shining, more evidently and closely punctured ; elytral punctures 
stronger and rather closer, 2nd interstice more deeply impressed at 
apex, and the tuberculation stronger; third stria also somewhat 
impressed. From. sobrinus it can be distinguished by its larger 
size, the distinct and wegular rows of punctures on the elytra,
