centre, coarsely rugose anteriorly to just beyond the long, 
narrow, transverse nodosity and posteriorly scabrous, the 
anterior edge furnished with two prominent tubercles; the 
whole surface hairy. Scutedlum obsolete. Elytra equal in 
breadth and one-fourth longer than the prothorax, sides sub- 
parallel, irregularly punctured, densely hairy, especially 
laterally and towards the apex, the declivity commencing 
abruptly behind centre; the fundus very hairy, with an 
uneven surface and punctured, the dense hairs forming two 
longitudinal ridges on each elytron, the one nearest the 
suture extending the whole length of the declivity, the outer 
one ceasing half-way down and causing the appearance of a 
depression ; the margin of the fundus not clearly defined. 
Length 3°75, breadth 2 mm. 
Hab. Mt. Matang, Borneo (Bryant). 
The declivity of this curious species is difficult to describe 
adequately, owing to the dense hair and the peculiar way in 
which it is brushed up into two ridges. There is no other 
species known to me of this truncate form of the genus Xyle- 
borus that is at all similar. 
Xyleborus coartatus, sp. n. 
@. Oblong, brownish yellow, moderately shiny. Front 
subconvex, coarsely punctate, sparsely hairy, with a trans- 
verse row of pale hairs over the mouth ; the eyes very slightly 
emarginate, the vertex shiny. Prothorax semi-elliptical and 
slightly narrowed at the base; a short transverse gibbosity, 
anteriorly rugose, posteriorly furnished with rather large 
shallow punctures on a shagreened surface ; the basal lateral 
angles obtuse, the anterior edge with four to six prominent 
tubercles. Scuéellum semicircular and shiny. Hlytra one- 
third longer and the same breadth at the broadest part as the 
prothorax, laterally rounded and broadest in the middle ; 
striate-punctate, interstices flat, with uniseriate rows of hairs ; 
the strial punctures also piliferous, but the hairs shorter ; the 
declivity commencing before the apical third and depressed 
on each side of the suture ; the apical margin very distinct. 
Length 2°75, breadth 1:2 mm.

&. Pale yellow, head concealed. Front convex ; surface 
smooth, with a row of pale hairs over the mouth. Prothorax 
slightly longer than broad, with the sides slightly rounded 
and narrowed anteriorly ; the anterior declivity deeply exca- 
vate, with rounded lateral edges ; the anterior edge extended 
centrally and bisinuate, furnished with a central, recurved,
