30 Lt.-Col. Winn Sampson— Notes on 
XAXyleborus glaucus, sp. n. 
Very dark reddish brown, legs and antenne yellow. Front 
subconvex, depressed laterally over the mouth, with a slight 
longitudinal median ridge interrupted with a central fovea; 
surface shagreened, with scattered longitudinal rugosities ; a 
transverse row of yellow hairs over the mouth, and the eyes 
nearly bipartite. Prothorax subglobose, rounded and de- 
clivous in front and contracted basally, anteriorly rugose, 
with numerous apical tubercles, faintly punctate behind the 
central node. Scutellum semicircular, sinall, black, and shiny. 
Elyira one-eighth longer than, and equal in breadth at the 
broadest part to, the prothorax; the sides subparallel, slightly 
divergent towards the declivity, which commences at the 
centre; the surface obscurely striate-punctate, the sutural 
angle at the commencement of the declivity divergent and 
pointed ; the declivity obliquely truncate, the fundus being 
sharply margined all round; the surface slightly convex, with 
three distinct rows of punctures; the interstices flat, the 
second one having a few scattered punctures, the rest smooth ; 
the whole surface of the fundus having the appearance of a 
faint “bloom” on it, the apical extremities of the suture are 
thickened and somewhat divergent. The abdominal segments 
are very narrow except the apical one. 
Length 5:4, breadth 2°4 mm. 
Hab. Penang (Bryant). 
In this species the eyes are so deeply emarginate-as to be 
practically bipartite. 
Xyleborus circumcisus, sp. 0. 
Brown, the prothorax slightly paler and similar to the 
front, antenne, and legs. Front subconvex, with a slight 
median longitudinal line extending from the mouth as far as 
can be seen towards the vertex ; the surface sparsely covered 
with longitudinally ‘elongate rugosities on a_ shagreened 
ground; a thick transverse fringe of pale yellow hair over the 
mouth. Prothorax barely one-fourth longer than broad, the 
sides and front rounded, the posterior angles obtuse, the 
surface anteriorly transversely asperate to the median eleva- 
tion, posteriorly very regularly and minutely punctured; the 
whole surface, especially tie sides, covered with longish 
semi-recumbent yellow hairs. Scute/lum rather prominent, 
but small, dark, and shiny. E/ytra equal in breadth at the 
base to the prothorax and one-half longer, the sides sub- 
parallel to just before the declivity, where they are constricted,
