Supplement by G. W. Kirkaldy 



to 



HEMIPTERA. 



Vide pp. 93 — 174 hujus operis torn. in'. 



This second contribution deals principally with the Auchenorrhynchous Homo- 

 ptera ; I have, however, added species of the Heteroptera etc. described since 1902, as 

 well as new species and notes on previously known forms. 



The total number of the Hemiptera so far described from the Hawaiian Islands 

 is 305, or, if we exclude the 63 determined species of Coccidae, Aleyrodidae and 

 Aphidae, which greatly swell the non-endemic total, 242. Of these 226 are not 

 known elsewhere, though I have grave doubts as to the endemicity of some of them. 



The Hemipterous fauna is now seen to lack representatives in many of the most 

 important families, only the following six containing undoubtedly endemic forms, viz. 

 Myodochidae, Nabidae, Reduviidae, Anthocoridae, Miridae and Acanthiidae, among the 

 26 recognized Heteropterous families, and by four only of the 14 Homopterous families, 

 viz. Tettigoniidae, Fulgoridae, Asiracidae and Chermidae, that is to say, by 10 out of 

 40, or exactly one-fourth ! But this scanty representation is still better shown by the 

 fact that out of these ten, only seven are represented by more than ten species each, 

 and that none contain more than one subfamily, except the Myodochidae, which have 

 an endemic subfamily, Metrarginae. 



Although there are several species still to be described, I think that all but a very 

 few genera have been accounted for. 



In the Cimicinae, Oechalia and Coleotichus are possibly endemic, as regards their 

 species, but, on the other hand, these may very possibly be found in Samoa or Tahiti, 

 the endemic Hemipterous fauna of which is unknown. 



' I regret that I have to announce the decease of Mr Kirkaldy, which has occurred while these pages 

 have been in the press, so that they have not had the benefit of his revision. The residence of Mr Kirkaldy 

 in the islands for some years, induced a change in his views on numerous points, so that the alterations in 

 this supplement are of considerable extent and importance. The species with a number prefixed are not 

 hitherto enumerated in the Fauna, and are practically additions, though some were described previous to 

 Mr Kirkaldy's first treatment of the subject. Editor.
