NOTE XVIII. 



ON SOME NEW BRENTHIDAE FROM 

 JAVA AND SUMATRA 



BY 



Dr. ANGELO SENNA, 



Assistant in the R. Museam, Florence. 



The present note is based upon a small collection of 

 Brenthidae , belonging to the Leyden Museum, kindly placed 

 in my hands by Mr. Ritsema. The greater number of spe- 

 cimens are from Java and Sumatra, and amongst well- 

 known species I have found some interesting novelties of 

 which I give here the descriptions.
