232 ECTATORHINUS HASSELtl. 



E. Adamsi Pasc. of which my collection contains nume- 

 rous specimens for which I am indebted to Mr. Lewis's 

 captures in Japan ^), resembles the new species from Su- 

 matra and Malacca, but can easily be distinguished by its 

 smaller size , and principally by its different sculpture and 

 its more elongated shape. 



I have much pleasure in dedicating the new species to 

 Mr. A. L. van Hasselt, commander in chief of the above 

 mentioned Expedition.
