Van der Wulp in his Cat. Dipt. S. Asia also gives Borneo, the 

 type being recorded from Macao, S. China. 



In Brit. Mus. coll. are 5 specimens from Kuala Lumpur and 

 Sunghai, S. Perak, Federated Malay States; also specimens sent 

 to me by Dr. Kertesz for identification from Perak, and from 

 Sylhet, Assam, others from Batu Tisa, Federated Malay States, 

 Stanton coll. A very pale faded specimen determined by Walker 

 as this species from Sarawak, Borneo, is probably correctly 

 identified.
