Reference Tables of the Hawaiian Delphacids and of Their 

 Food-Plants. 



COMPILED BY WALTEE M. GIEFARD. 



Tlie compilation of the following ready reference lists of 

 the known species of Hawaiian Delphacids and of their food- 

 jdants was undertaken in the hope that it might in a measure 

 he of some assistance to local collectors of this interesting fam- 

 ily, (^uitc a iiiimlx'i" of fond-plants have hccu added in these 

 lists to those already known and ])revionsly recoi'dcd, hut much 

 has yet to he learned in this particular direction hy continued 

 systematic collecting. I haye followed Mr. Frederick Muir's 

 I'cccut lieyiew of the Hawaiian Del])hacidae* in listing the 

 genei-a and sjx'cies togethei' with the compilations of food-plants 

 r(';'oi'd('(l therein as well as those puldished in Fauna Hawaii- 

 cnsis hy my friend, the late Air. George W. Tvirkaldy.f To 

 these has been added information su])])li('d me by Messrs. 

 Timherlake, Swezey, and Bridwell and obtained by them on 

 recent collecting trips in the mountainous region of the Island 

 of Oahu. The author has also included his results of sys- 

 tcnuitic collecting of Delphacids for AIi'. Aluir on two recent 

 \isits to the Kilanea region (4,000 feet elevation) on the 

 Island of PTawaii and on Tantalus (l,r)00 feet eleyation), 

 Oahu.:}: Continued systematic collecting of our eudcMiiic Dcl- 

 ])hacids and other Tlomoptcra will undoubtedly furnish present 

 and future workers in this gi-oup with a still better knowledge 

 of the trees and plants on which they feed and this in turn will 

 he of material assistance in the future work of identification. 



T am much indebted to my friends, Messrs. Muir, Swezey, 

 and Timberlake, for their generous assistance by means of their 

 collections and field notes.

 collector are those taken from his field notes which give full details 

 and data as regards environment and the special food plants under 

 observation. The individual specimens in his collections bear corre- 

 sponding numbers.
