one finds that in many instances ''species" have not the same 

 valne as among continental fannas, and one hesitates to give 

 many forms that status, but it is necessary for both systematic 

 and Inological studies that such forms be separated and named ; 

 whether as species, snb-species or varieties must be left to 

 the idiosyncraeies of the describer. 



In the Fauna Hawaiiensis Kirkaldy enumerates forty-six 

 species (omitting two, Nesoplelas artemislae and Nesosydne 

 lealii) under six genera. The present paper adds twenty-seven 

 species and three sub-species to the list, thus bringing it up 

 to seventy-eight ; these are still under six genera, but somewhat 

 differently arranged. 



Gexeua of Aloiiini. 



1. (4) First joint of antennae very sliort, broad- 



er than long, second joint short and thick, 

 often ovaliform or sub-ovaliform. (All 

 macropterous. ) 



2. (3) Two median frontal carinae, approximat- 



ing at base or apex, or both, or even 



meeting together, but not forming a stalk. Leialoha 



3. (2) A single median frontal carina, forked at 



extreme base if at all. Nesodryas

(B.) Broader, more robust forms. Subgen. Nesothoe 



4. (1) First joint of antennae distinctly longer 



than broad, second joint cylindrical or 

 only slightly enlarged in middle. (Most- 

 ly brachypterous, few macropterous). 



5. (8) Two median frontal carinae. 



6. (7) Tegmina reaching well beyond middle of 



abdomen. Aloha 



7. (6) Tegmina very short, not reaching to mid-

8. (5) One median frontal carina, forked or 



simple.
