medium et maculis binis vel terms anteapicalibus fusco- 
brunneis; antennis nigro-fuscis scapo et dimidio basali 
articulorum 3:ii et 4:i albidis ; elytris subseriatim profunde 
punctatis. Long, corporis 12 mm. 
Borneo: Santubong. 
Easily known by the design. Another specimen from 
Kuching is much smaller, only 7 mm., but differs other¬ 
wise only by a brown spot at the shoulders and by the 
unicolorous joints of the antennae.

I have not been able to compare this new species with 
any one of the hitherto described forms. It seems, 
however, to differ from the generic characters only by 
the absence of the subapical transverse groove of the 
prothorax.
