22 Transactions. 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,
