A List of the Dssepibed Hemiptepa (exsludin^ Alaypodidae 

 and Coccidae) of the Hawaiian Islands, 



BY G. W. KIRKALDY. 



The Hawaiian Hemiptera are remarkable for the fact that they 

 are represented endemieally by the following families only, viz: 

 Cimicidae, (probably), Lygaeidae, Myodochidae, Nabidae, Red- 

 uviidae, Anthocoridae, Miridae, and Acanthiidae, among the 26 

 recognized families of Heteroptera, and by the Tetigoniidae, Ful- 

 goridae, Asiracidae and Chermidae only, out of the 14 Homopt- 

 erous families: that is to say, 12 out of 40. These figures, however, 

 do not really represent the true constitution of the Fauna, as, out 

 of these 14, only 6 are represented by more than ten species each , 

 viz: Myodochidae, Nabidae, Miridae, and the first three Homop- 

 terous Families, (t) 



The absence of Cicadidae, Cercopidae, Aradidae, Pyrrhocori- 

 dae, Tingidae, and Gerridae, so well developed in other parts of 

 the Pacific, and the feeble representation of the mighty Cimici- 

 dae, Lygaeidae and Reduviidae, show, more plainly than many 

 words, the real condition of the Fauna. 



The leading characteristic of the Hawaiian Hemiptera is their 

 tendency, and almost complete adaptation, to an arboreal life. 

 All, or practically all, the Hawaiian Asiracidae — one of the most 

 important families numerically — are arboreal, a phenomenon 

 otherwise known, so far, only in one peculiar Australian genus, 

 Proterosydne Kirkaldy. Acanthia, usually a riparian genus, has 

 one species, representing, no doubt, the ancestral form, inhabit- 



fi) In calculating, I have taken into account a large number of 

 manuscript species.
