lines divided at the base by a very fine carina ; the outer line of 

 punctures has a tendency to encroach on the inner line, and towards 

 the apex the lines are somewhat confused. 



It is doubtful to which sex the specimen described belongs. 



CAUTIRES. 



Rostrum none. Antennae of the male with a long compressed 

 branch proceeding from the base of the third to tenth joints ; very 

 strongly dentate in the female. Thorax with seven areolets, the two 

 lateral ones sometimes obsoletely divided. Elytra as in Bulenides. 



The males of this genus are easily known by the branches of the 

 antennal joints arising from the base of the joints. The females 

 have the antennae very acutely dentate.

Hah. Sarawak ( Wallace). 



The lateral areolets of the thorax are sometimes not very distinctly 

 divided, but the ridge separating them is generally well marked. 

 The elytra have each four costas, the interstices with two rows of 

 black punctures, the rows divided by a fine line, not by a distinct 

 costa. 



Cautires excellens, var. 



$ . This variety (as it seems best to consider it for the present) 

 differs from the female of C. excellens from Borneo in being rather 

 smaller, in having the base of the elytra more red, but especially in 

 having the joints of the antennae differently formed ; the branches 

 arise from the base of the joints, and not from the apex, being thus 

 somewhat intermediate in form between the male and female of the 

 Bornean examples.
