AntcnnjB with the first, second, and third joints piceous 

 and longly pilose, fourth joint and extreme base of tliird joint 

 dull ochraceous; first, second, and third joints almost sub- 

 equal in length, fourth joint short, cylindrical, and only 

 moderately pilose ; pronotal lateral angles produced in long 

 acute spines, their apices slightly or scarcely recurved ; 

 corium with the l^asal area of lateral margins distinctly 

 spinous ', rostrum just passing the intermediate coxeb, its apex 

 black.

Hab. S.E. Borneo {Doherty^ Coll. Dist.) ; Mount Ophir 

 (Brit. Mus.). 



This species is to be recognized by the acutely produced 

 lateral angles of the pronotum. A damaged specimen from 

 Mount Ophir in the British Museum was labelled by Stal 

 " ^. acM^MS?," and was incorporated under that name by 

 Walker.

There seems considerable doubt whether Mr. Kirby's type 

 is a Ceylon specimen. The locality " Mungphe " should be 

 probably " Mungphu," a locality in Northern India.
