HEMIPTERA. "-^/^v. 

 By G. W. Kirkaldy. '""''•t' 



Sj 1. General Remarks. 



The Heteropterous Hemiptera or Rhynchota of the Hawaiian Archipelago have 

 been studied to a small extent by F. B. W. White and T. Blackburn, on the collections 

 made some quarter of a century since by the latter. In iS88 the total number recorded 

 was 26 genera and 48 species'. To-day 43 genera and 64 species are recorded. The 

 Auchenorrhynchous Homoptera were not dealt with by the British authors, but a few 

 species were noted by C. Stal and V. Signoret, in all 3 genera and 4 species. Five genera 

 and 14 species are here catalogued, and this will be materially increased when my studies 

 on the Jassinae and Asiracinae are completed. Of Stenorrhyncha nothing was previously 

 known, and only 2 genera of Psyllidae, with a single species each, are added. I know of 

 no records of Aphidae and have seen no specimens. I have not examined any Coccidae 

 and am principally indebted to the publications of T. D. A. Cockerell and W. M. 

 Maskell for the records of the 48 species included in this account. Thus the total 

 number of Rhynchota — both Heteroptera and Homoptera — amounts at present to 126 

 species, of which at least one-third are recent introductions. 



My best thanks are due to Dr Sharp for his unfailing courtesy and kindness in 

 giving me information upon every topic connected with the Hawaiian Fauna, while 

 Dr L. O. Howard was so kind as to advise me regarding records of Hawaiian Stenor- 

 rhyncha. Mr Edward Saunders also gave me some very valuable help in lending me 

 for examination and comparison certain Palaearctic Miridae and in affording me much 

 information. My greatest difficulty has been the inability to examine the type-specimens 

 of the previously described Hawaiian Fauna, as the Directors of the Perth Museum 

 — where White's types, now unfortunately in bad condition, repose — refused to allow 

 these specimens to be taken away for study. Dr Aurivillius however sent me, with his 

 usual kindness, the types of Oechalia patruelis ■d.wdi pacific a Stal, Hyalopcpliis pcllucidtis 

 Stal, and Nysiiis cacnosiihis Stal. Mr Blackburn also kindly sent for examination 

 cotypes of his Nabis rubritinctus, koelensis and oscillaiis, but I regret that these 

 completed the list of all that he was able to send me. 



' According to ilieir supposed validity at the present time.
