LI. — Descriptions of some Rhynchota from Ruicenzori. 

 By W. L. Distant. 



These descriptions refer to the collections made by the recent 

 British Museum Expedition to Ruwenzori in Central Africa. 

 The full enumeration of the species will subsequently appear 

 in the ' Transactions of the Zoological Society of London.' 

 I have previously described in these pages some new species 

 collected by Mr. Scott Elliot during his journey to the same 

 locality. The types are in the British Museum.
