Hob. Mt. Santubong, 2600 ft., February 4, 1900. One male 



specimen. „ ,. i , , :i 



Black, with rather more than the basal half of the elytra red. 

 Antennae about three-fourths the length of the body, with the 

 joints from the fifth to the tenth produced into a tooth at the 

 antero-distal angle. Prothorax rather strongly rounded at the 

 sides and widest about the middle; the disk with two small 

 velvety tubercles placed barely in front of the middle. _ Elytra 

 slightly widening from the base up to about the posterior third 

 or fourth, and thence narrowing towards the apex, where each 

 ends in a small sutural spine ; the disk of each with a rather 

 feeble costa extending from the base to a little bey ond_ the middle.

 the dark apical area of the elytra is less extensive ; the prothorax 

 is less rounded, is widest behind the middle, and on the disk has 

 but a single median cariniform tubercle.
