Platypodide and Scolytide., 29 
breadth and one-fifth longer than the prothorax; sides sub- 
parallel, very slightly divergent at the declivity ; the surface 
shiny and obscurely striate-punctate, the interstices being 
minutely and irregularly punctured; the declivity very 
abrupt and commencing rather behind the centre; the fundus 
subconcave, but elevated on each side of the suture towards 
the apex ; three distinct strie of large but shallow punctures ; 
the interstices very finely and irregularly punctured, the 
sutural interstices on the elevated portion being armed with 
single rows of large tubercles, which are very prominent 
when viewed laterally; the margin clearly defined and circular, 
granulate on the inferior apical border, 
Length 3°5, breadth 1:5 mm. 
Hab. Mt. Matang, Sarawak, Borneo (Bryant). 
Xyleborus versicolor, sp. u. 
Elytra dark reddish brown, the remainder of the body, 
legs, head, and antenne dirty yellow. Front convex, with 
shagreened surface, anteriorly finely tubereulate, with a 
transverse row of pale hairs over the mouth and a minute 
shiny indentation in the centre between the deeply emar- 
ginateeyes, Prothoraw one-tenth longer than broad, parallel- 
sided, with rounded front and six small recurved prominences 
on the anterior edge ; the anterior surface transversely rugose 
and hairy as far as the slight postmedian nodosity, posteriorly 
shiny and finely punctured; the posterior angles obtuse. 
Scutellum semicircular and shiny. lytra one-tenth longer 
and the same breadth as the prothorax; sides parallel, with a 
very slight divergence towards the declivity, striato-punctate, 
the punctures decreasing in size towards the declivity; the 
interstices flat and shiny, with uniseriate punctures, the 
nearly vertical declivity commencing beyond the centre ; the 
fundus subcircular, acutely margined and fringed with 
minute hairs, subconcave at the sides and elevated towards 
the suture, with three rows of large variolate punctures on 
each elytron; the interstices irregularly dotted with piliferous 
tubercles on a dull surface, the sutural interstices somewhat 
raised and more strongly tuberculate apically, the margin 
rugose half-way up the sides, 
Length 2°5, breadth 1:1 mm. 
Hab. Penang (Bryant). 
Allied to X. truncatus, Er., and X. amputatus, Bldf., 
from both of which, however, it differs by the elytral structure 
and colour, and from the latter also by the absence of the 
prothoracie tuft of hair,
