Two female examples agreeing closely with the description of T. inops were obtained, 
one in Borneo at the Baram River, the other in the island of Batjan. The types were from 
Ajer Mantjur and Sungei Bulu in Sumatra.

!) Tam indebted to my friend Mr. F. Cambridge, who has been recently studying the Cteniform
