Kelis'ui s]>p. — Mr. Giffard exhibited large series of two 

 species of this Delphacid geiins, fi'oni the Island of Hawaii, 

 witli the following notes: At Kilauea, early in September, he 

 took a large series of both sexes together with nymphs of a 

 species which Mr. Tind>erlake had discovered early in August 

 on the grass Descharitpsln aiisiialis. The species is believed to 

 be new, and l)y the edeagus is closely allied to A', sivezcyi of 

 Oahu. 



Of the second species, a good scries of both sexes and

 Hawaii and on Oahu at soa level, but has since been taken on 

 Haleakala, ]\raui, by Hridwell in 191S, and by Timberlake

 to eradicate this local colony. The infestation was apparently

 area had been laid out instructions were given to cut and 

 burn all Sadleria and Asplenium stalks and stumps on the 

 area, and appliances were secured to l)urn over the ground aft-
