130 Christmas Island. 



Order 6.— HOMOPTERA. 

 By W. r. KiEBT, F.L.S., F.E.S., etc. 



(PLATE XV.) 



Of this Order eleven species are enumerated in the following list, 

 all of which, so far as is known, are peculiar to the island. Of 

 these, seven are now described as new, one being considered to 

 represent a new genus, the other four having been described by 

 me in 1888 fi'om Mr. Lister's collection; of these the descriptions 

 are here reprinted. It is curious that six species out of the eleven 

 belong to a single family, the Ricaniidae.
