Hob. Dorey; Aru. 



There is a vestige of another sti-ipe on each side of the pro- 

 thorax, making live in all ; there are also a few nearly obso- 

 lete brownish spots on the base of the elytra ; but in this 

 genus colour is very uncertain *. 



* Another species in my collection, from one of the Fiji islands, is very 

 like the above in coloration and outline, but, inter alia, is huely granu- 

 lated on the prothorax ; it may be described as follows : —
