but regain their normal breadth at the apex of the declivity ; 
the surface irregularly punctured, most of the punctures 
being furnished with longish pale yellow hairs; the declivity 
commences at the apical third and is nearly vertically trun- 
cate ; the surface convex, but depressed laterally except at 
the suture, which is elevated towards the apex; the interstices 
are separated by tliree faint rows of impunctate stria, and 
are uniformly covered with small, round, shiny granulations 
and irregularly placed, long, p: ale yellow hairs; the margin is 
furnished with small, blunt, irregular teeth. 
Length 374, breadth 1-4 mm. 
Hab. Penang (Bryant). 
Xyleborus aspersus, sp. Nn. 
Brown, the elytra darker than the prothorax or head. 
Front subconvex, depressed laterally, a short median longi- 
tudinal line above the central fovea; the surface shagreened, 
with scattered longitudinal rugosities, and a transverse row of 
yellow hairs over the mouth ; eyes very deeply emarginate. 
Prothorax subglobose, anteriorly transversely rugose up to 
and slightly beyond the central node, the posterior portion 
being very minutely punctured ; the anterior edge with several 
tubercles, of which the four central ones are the most promi- 
nent. Scutellum semicircular and very shiny. Elytra the 
same breadth and practically the same length as the prothorax, 
very slightly divergent towards the declivity, and the sides 
subparallel, vaguely striate-punctate, the declivity commencing 
behind the centre and abruptly truncate ; the fundus 
without any trace of striw, subconvex; the whole surface 
closely variolous, the margin sharply defined and subcircular, 
the sutural angles slightly divergent at both the upper and 
lower extremities of the fundus, the apical edge somewhat 
rugose.

The emargination of the eyes is similar to that of X. glaucus 
described above. 
XAXyleborus bellus, sp. n. 
Dark brown, the prothorax, legs, head, and antenne 
lighter than the elytra. roné subconvex, rimose, on a 
coarsely shagreened surface; a faintly marked longitudinal 
central line from the vertex to the centre, a transverse row 
of pale hairs over the mouth; the eyes deeply emarginate.
