XXXII. — Some new Species o/Tpidfe and Platypodidte in the 

 British Museum, By Lt.-Col. Winn Sampson, F.E.S. 



The first two species described are from specimens received 

 through Mr. Guy Marshall from Mr. Urich, and found on 

 cacao-plants in Trinidad. The only other specimens of 

 X. urichi in the British Museum are two received in 1905 

 from Angola (Portuguese West Africa), and reported as 

 damaging the cacao-plants there, but whether to a serious 

 extent is not stated.
