SMALL COLLECTION OF HOMOPTERA FROM BRITISH GUIANA. 125 



Apart from the new species here described, the collection also 

 contained two very rare species. One, Odontoptera carrenoi, 

 Sign., a Fulgorid, described by Signoret from an unlocalised 

 specimen, was quite new to the British Museum Collection, and 

 was the first example I had seen ; another, a Jassid, belonging 

 to the genus Peltocheirus, is represented by a single specimen, 

 quite distinct from the type P. higibbosus, Sign., but which may 

 have been described elsewhere and perhaps under another 

 generic name.
