HEMIPTERA 



533 



FuLGORiDAE consist only of Cixiini, in two genera, the endemic lolania (several 

 species, only one yet described) and the cosmopolitan Oliarus, with several endemic 

 forms. 



AsiRACiDAE are well represented and comprise several endemic genera and a large 

 number of species. 



PoEKiLLOPTERiDAE, IssiDAE, Tettigometridae and Derbidae are absent, the first 

 named having a single immigrant. 



Chermidae are rather numerous, but very variable, and scarcely studied. 



My thanks are due to the following gentlemen : to Dr R. C. L. Perkins for loan 

 of specimens and much help in various ways ; to Mr W. M. Giffard for the gift of his 

 valuable Hemipterous collections made in various localities, but principally on Mt. 

 Tantalus, Oahu ; and to my colleagues Messrs F. W. Terry and O. H. Swezey, for 

 specimens. 



Heteroptera 



For a sketch of the classification of the Heteroptera see Kirkaldy, 1907, P. Haw. 

 E. S. I. 135 et seqq. ; and 1908, Can. Ent. xl.

Oechalia. 



As stated elsewhere, P. Haw. E. S. i. pp. 141 — 3, I feel certain that there are 

 two valid species of this genus, as there are two kinds of ova ; at the same time I do 

 not believe that the synonymy already given is incorrect. 



Oechalia grisea, Burmeister. 



Oe. griseus, huj. op. in. p. 171. 



I have described some of the stages and figured an egg. Dr Perkins writes in 

 reference to other remarks in that paper, "You give a wrong impression as Oechalia 

 often swarms in Myoporum, Acacia koa and many others. I have seen hundreds in 

 a few yards of sugar cane and it is often very common near the coast and even in the 

 outskirts of Honolulu on foreign vegetation. The whole remark certainly gives no 

 idea of the ubiquity of this very abundant bug. It is on nearly all native trees, both in 

 egg and other stages, as well as on low vegetation." Recently, I have taken it at 

 Kilauea (Hawaii) on Myoporum, Acacia koa and ferns.
