 form, probably a native species, were examined and no trace

 opinion that the pest might be eradicated if prompt and vigor-

 the Superintendent of Forestry asking the cooperation of the 

 Board of Agriculture and Forestry to this end, stating at the

 vidual members of the Entomological Society would be gladly 

 given. 



Messrs. Swezey and FuUaway were appointed a committee 

 to prepare a memorial for Mr. H. O. Marsh, a former member 

 whose death had recently been noted.

New Hawaiian Delphacidae (Homoptera). 



BY F. MUIK. 



The list of Hawaiian Delpbacidae has been considerably

 Messrs. Bridwell, Fullaway, Giffard, Rock and Swezey. In 

 the present paper eighteen new species, one new sub-species 

 and two new varieties are described, but a considerable portion 

 of the collected material has not yet been worked, chiefly con-

 This latter material contains several new species. An exten-

 food plants of most of the new^ species and of some of the old 

 ones are recorded. The taking of Nesodryas laJca (Kirk.) and 

 Ilhiirnia monticola (Kirk.) is of interest as no specimens of
