422 Mr. W. L. Distant on Coreide. 
Antenne with the first, second, and third joints piceous 
and longly pilose, fourth joiat and extreme base of third 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 basal area of lateral margins distinctly 
spinous ; rostrum Just passing the intermediate coxe, its apex 
black. 
Long. 15 millim.; exp. pronot. angl. 6 millim. 
Hab. 8.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 
‘¢ A. acutus?,”’ 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.
