My object is to show that there are no insuperable or even formidable 

 difficulties to contend with. Australia would doubtless join us, and thus 

 give the question an Australasian weight. 



I know this is an Imperial question, and that it would be almost as 

 easy for the Home Government to make a new coin as to reproduce an 

 old one, which they are continually compelled to do ; but if the change is 

 not carried out a.t Home, that fact should surely not prevent us from 

 adopting it here if found desirable. 



Akt. IV. — A List of the Hemiptera (excluding Sternorrhyncha) of the 

 Maorian Subregion, tvith Notes on a Feio of the Species. 



By G. W. KlEKALDY. 



[Read before the Philosophical Institute of Canterbury, 5th August, 1908.] 



The list of Hemiptera given in the "Index Faunae Zealandiae " (1904 

 is so inadequate as regards the correctness of the nomenclature, and as 

 indicating the probable endemicity or otherwise of the species included, 

 that I have been tempted to prepare a new list, and to add a few notes 

 on one or two of the forms. The total number now enumerated of the 

 Heteroptera and auchenorrhynchous Homoptera — that is to say, the 

 bugs and leaf-hoppers — is seventy-seven species (this excludes eight 

 recorded in almost positive error). Of these, thirteen may be positively 

 assumed to be non-endemic ; of the remaining sixty-four, only about 

 forty may be reasonably assumed to be endemic, but a considerable 

 proportion of these belong to groups scarcely known yet outside the 

 palearctic region. 



The forms which may be considered at once pretty safely as endemic 

 are the species of Uiiopalimorplia, Oncaco)itias, Acamhia, Anisops, most 

 of Cicadetta, and probably some at least of Oliarns, Gixius, and Nysius. 

 The rest are entirely conjectural. 



The valuable contributions by Hutton, Hudson, Fereday, and others, 

 in the " Transactions of the New Zealand Institute," dealing with the 

 fauna of the country, lay stress on the almost entire absence of 

 Hemiptera, and especially of Homoptera ; but I am sure that this is 

 entirely a mistake. 



The only other Pacific fauna of which the Hemiptera are at all well 

 known is that of the Hawaiian Islands. Although endemic Coccidce and 

 Aphidce are absent, I estimate the total number of endemic Hemiptera at 

 little less than 360 ; of these, 138 have already been described, over a 

 hundred more are in manuscript awaiting early publication, and I have at 

 least a hundred more before me. These figures do not include thirty-six 

 introduced Heteroptera and Auchcnorrhynciia, as well as over a hundred 

 coccids, aphids, and aleyrodids, all introduced. 



In the Hawaiian fauna the following families are represented endemic- 

 ally : LygceidcB, Myodochidce, Nabida, Reditviidce, Antliocoridce, Miridce, 

 Acanthidce, TettgoniidcB, Fidgoridce, Asiracidce, and Chermida, and pos- 

 sibly Cimicidce, — that is, eleven or twelve out of forty recognised families. 

 In New Zealand all these are present, and we have to add ThyrcocoridcB, 

 Aradidce, Enicocephalidce, Gerridce, Notonectidce, CorixidcB, Cicadidce,
