 Ceylon, where it is found both on the living and dead 

 branches.

Flab. Ruby Mines, Burmah. 



Head black, sparsely covered with piliferous punctures, 

 the hairs very long, especially centrally ; there is a ti'ansverse 

 fringe of long yellow hairs over the mouth, and anteriorly a 

 central small shining depression with a slight longitudinal 

 carina posteriorly, the general surface shagreoied ; protborax 

 semielliptical, shiny black, rugose-asperate in front, inter- 

 spersed with longish hairs, gibbous, with scattered piliferous 

 punctures behind and a medial posterior group of pale hairs • 

 scutellum triangular and polished. 



Elytra nearly twice as long as the protborax, with sub- 

 parallel sides and excavate from the middle, punctate-striate, 

 the punctures being large, round, and shallow ; the inter- 

 stices before the declivity are smooth, with small uniseriate 

 piliferous punctures down the centre; at the commencement 

 of the declivity each interstice has a sharp tooth, with one or 

 two longish hairs close to it ; interstices 3 and 4 also have a 

 few teeth distributed along them towards the apex ; the 

 sutural striae have a single row of small tubercles after the 

 commencement of the declivity. 



This species belongs to Eichhoff's division *^ of the genus 

 Xyleborus, but is larger than any described by that author.
