KiRKALDY. — A List of the Hemiptera of the Maorian SiLhregion. 23 



CercopidcB, Aleyrodidce, and Coccidce, all of which may be (and five cer- 

 tainly are) endemic. 



The principal Hawaiian plants, fiom a hemipterological point of view, 

 ■eive Naiii (= Metrosideros) polymorpha, Pipturus, Myrstne, Ipomoea, Sida, 

 various tree-ferns, Myoporuvi, and, to a less degree, Acacia koa, Cya- 

 thodes, Elceocarpns, Etigenia, Freycmetia, Dodoiicea, and Bobea. Of 

 these, I find, on reference to Kirk's great work on New Zealand forest- 

 trees (the only such work I have for reference), that Gyathodes, Elceo- 

 carpns, Eugenia, Dodoncea, Nani, Myoporum, and Myrsine — and, I sup- 

 pose, Freycinetia, Ipomoea, and Sida also — are well represented in New 

 Zealand. It is almost impossible to believe that they too are not the 

 shelters or food plants of a large hemipterous fauna there. 



I have estimated the total endemic Hawaiian fauna at little less than 

 360. Taking into consideration tiie hemipterous faunas of the Hawaiian 

 Islands and the British Islands, and the coleopterous and lepidopterous 

 faunas of New Zealand, the British Islands, and the Hawaiian Islands, I 

 have no hesitation in estnnating at least 750 species of endemic Hemi- 

 ptera for New Zealand, and I thmk that this is ideally much too little. 



As it is just possible that some of the members of our Society may feel 

 moved to remedy our deplorable state of knowledge — or, rather, want of 

 knowledge — of the New Zealand HemijJtera, 1 venture to give a few hints 

 as to what may prove to be the best method of securing specimens. 



To a considerable extent collecting in New Zealand will be not unlike 

 collecting in the Hawaiian Islands. In the latter, almost all the endemic 

 species are arboreal. They are to be obtained, therefore, by careful 

 beating of the leaves, twigs, and branches, especially the last, but, better 

 still, by searching. The wonderful native grasses, however, must not be 

 neglected, as they are certain to have a large fauna. When collecting 

 leaf-hoppers, searching is often best, but if not, then the branches should 

 be beaten into a large, rather deep net, as the very agile hoppers will 

 jump at once right out of an ordinary umbrella. It is very important to 

 identify the food-plants, and also the uymphal stages, of the various 

 Hemiptera, especially of the plant-eating kinds, which are often much 

 restricted in that way. In Hawaii, however, such carnivorous kinds 

 as Beduviolus (Nabidce) are also considerably thus restricted. In the 

 forests themselves " sweeping " will be of little avail, this method of 

 capture being reserved principally for grasses. One fruitful method 

 of capturing certain Miridce, Anthocorida, Ploiariince, &c., is to beat 

 dead trees which still retain their leaves, though these are withered ; 

 such trees will be found near recent forest-clearings. 



Of course, these remarks are based on methods of collecting which 

 have been found effective in the Hawaiian Islands, but I believe they 

 will also be found effective in New Zealand. I have only to add that 

 I will be very pleased to help any one who contemplates collecting 

 Hemiptera in New Zealand if he will write to me at Honolulu.
