ET Mr. Walter I’. H. Blandford on the 
Xyleborus pelliculosus, Kichh, 
Hichh., Rat. Tom., p. 336. 
Two examples, Kiga. 
I have not seen the type of this insect, and am less 
certain, than with other unseen species, that I have here 
the true X. pelliculosus. But the description fits it, and 
my doubt is rather owing to the fact that there exist 
other at present undescribed species of similar facies 
in the Oriental region. It is quite easily distinguished by 
the rather dense and almost downy pubescence, and the 
confusedly and finely punctured elytra, which bear only 
the feeblest traces of striz. One example is black, the 
other sordid testaceous. ‘The shape of the prothorax 
would lead me to put it in Hichhoff’s group + + + rather 
than +, but it is a distinct form, and not very closely 
related to any other described species. I have placed 
it in the neighbourhood of X. muticus, which is of 
similar build, without evident elevation of the prothorax, 
but that species has the elytra plainly lineato-punctate. 
Xyleborus muticus, sp. n. 
Fem. Elongata, cylindrica, subnitida, pilosa, rufo-picea, 
antennis pedibusque ferrugineis; prothorace oblongo, antice 
fortiter rotundato, supra parum gibboso, post medium punctis 
subaciculatis subtilibus notato; elytris lineato-punctatis, inter- 
stitiis subtilissime uniseriatim punctatis et pilosis, apice fortiter 
declivi, ad suturam subimpresso, striis impressis, interstitiis vix 
perspicue tuberculatis. Long. 3 mm. 
Two examples, near Kashiwagi. 
Ferruginous-pitchy, with rather long soft pubescence. Head 
ferruginous, dull, front convex, punctured at sides with a median 
impunctate slightly raised line, pubescence scanty and short except 
over mouth; antenne ferruginous. Prothorax oblong, base 
truncate, basal angles obtusely rounded, sides straight, slightly 
divergent from base towards apex, which is strongly rounded ; 
surface with only the slightest trace of a transverse elevation, 
thinly pubescent especially at sides and apex, its anterior third with 
rather close transverse asperities which become weaker, but are 
continued back to posterior third, which is very finely reticulate, 
dull and subaciculately punctuate, the punctures rather close at 
the sides. Seutellum rounded, piceous, shining. Elytra slightly
