Nesotociis uvunroi. — ^Nlr. (lifl'ard exhibited a specimen 

 taken by him dead at 20 Miles, Olaa, Hawaii, Sept., 1919. 



Kelisla spp. — Mr. Giffard exhibited large series of two 

 species of this Delphacid genus, from the Island of Hawaii, 

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

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

 species which Mr. Timberlake had discovered early in August 

 on the grass Deschampsia ausiralis. The species is believed to 

 be new, and by the edeagus is closely allied to X. swezeyi of 

 Oahu. 



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

 nymphs was taken by him at Kilauea early in September, on 

 the sedge Vincc7itia aiKjustlfoJla. This is A', sporoholicola, or 

 very closely related to it. It was originally taken at Puako on 

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

 Haleakala, Maui, by Bridwell in 1918, and by Timberlake 

 in 19] 9. So far the genus Kclisia is represented by two species 

 on Hawaii, two on Maui, and five on Oahu, all the species 

 known in the Islands occurring on Oahu except the one men- 

 tioned above from Hawaii. 



Syagrius fidvitarsis. — Mr. Giffard reported the discovery 

 by Mr. Fullaway and himself of a severe local infestation of 

 the native SadJeria ferns at 29 !Miles, Olaa, Hawaii, by the 

 Australian fern weevil, and reported on the measures taken 

 to eradicate this local colony. The infestation was apparently 

 confined to about seven acres, and after boimdary lines of the 

 area had been laid out instructions w^ere given to cut and 

 burn all Sadleria and Asplenium stalks and stumps on the 

 area, and appliances w^ere secured to burn over the ground aft- 

 er it had been bared. The Board of Agriculture and Forestry
