120 i\Ir. C. 0. Waterliouse on a new Dragon-JIij. 



Length of abdomen 2| indies ; length of hind wing 

 3-^ inches. 



Hab. — Borneo. 



Note. — Mr. MacLachlan, to whom I am much indebted 

 for assistance in giving the characters of this species, in- 

 forms me that he has seen a drawing in the possession of 

 Baron de Selys-Longchamps representing a species from 

 Sumatra identical with or closely allied to the one here 

 described, and he has reason to believe that it is the inten- 

 tion of that author to found a new sub-genus for the re- 

 ception of his species (which is also a female), on account 

 of the formation of the apex of the abdomen.
