Rhynchophorous Coleoptera of Japan. 123 
Xyleborus orbatus, sp. n. 
Mas. Brevis, subglobosus, subnitidus, ferrugineus, longius 
pilosus, prothorace transyerso, aeque rotundato convexo, anterius 
exasperato, posterius rugoso; elytris a basi usque ad apicem 
rotundatis, lineato-punctatis, interstitiis subrugosis uniseriatim 
punctatis. Long. 1:5 mm. 
One example taken with the last species at Kurigahara. 
Of the type of Xyleborus dispar, g. Very short and subglobose, 
somewhat depressed, ferruginous with very long scattered pu- 
bescence. Head with front nearly flat, reticulated, sparingly 
punctured and pubescent, eyes small, antenne testaceous. Pro- 
thorax one-third broader than long, base truncate, basal angles very 
broadly rounded, sides and apex strongly rounded, surface 
uniformly but not strongly convex from base to apex, which is not 
produced in front, asperate anteriorly, the asperities becoming more 
scattered and punctiform towards base, interstices finely reticulate 
except at extreme base. Scutellum triangular. Elytra as wide as 
prothorax and half as long again, with humeral angles rounded, 
sides rounded from base to apex, rather more strongly behind 
middle, surface uniformly convex with indistinct rows of shallow 
punctures, interstices with a single series of punctures bearing long 
hairs. Legs long, slender, testaceous; tibia feebly dilated and 
spined. 
This insect may be the male of X. germanus, M., 
or semi-opacus, Hichh. I have described it for the 
sake of completeness, and not because I think that any 
useful purpose is served by describing these isolated 
males unless they exhibit some salient features.
