added, the Heteropterous fauna of New Zealand remains one 

 of the poorest and most scanty of all, and this was certainly 

 my own impression when I was collecting there. As revised 

 by the late Mr. G. W. Kirkaldy in 1909,* the fauna now 

 includes 48 Heteroptera and 39 Auchenorrhynchous Hom- 

 optera, and of these some 40 species are endemic. Almost 

 without exception, the forms in the first division are of small 

 size and obscure colouring, but the second includes an interest- 

 ing series of nearly twenty endemic species of MelampsaUa 

 (Cicadidae) which are a conspicuous feature in the insect life 

 of New Zealand. As in the Hawaiian Islands, there are no 

 endemic A'phididae, though some introduced species are now 

 common ; but the Coccidae, which have been worked out in 

 an admirable series of papers in the Transactions of the New 

 Zealand Institute by the late Mr. W. H. Maskell, number 

 upwards of 90 endemic species, besides a score or more intro- 

 duced from other parts of the world. 



Another very poorly represented Order is the Hymenoptera. 

 As enumerated by Prof. T. D. A. CockereU,t the Anfhophila 

 include only 18 species comprised in three genera, Prosopis, 

 Halictus, and Paracollefes, the last-named being common to 

 Australia and New Zealand. Dr. A. D. Forel | records 

 19 species of ants, nearly all of which are endemic; and while, 

 the Fossores are not much better represented, and the true 

 wasps are entirely absent, a fair number of the Parasitica have 

 been described from the region. With the exception of' a 

 single species of Xiphydria, the Phytophagous Hymenoptera ; 

 appear to be entirely wanting ; and at present not more than 

 200 species of the Order in all are known from New Zealand, but 

 further researches are sure to add considerably to this number. 



We owe most of our knowledge of the New Zealand Diptera 

 to Prof. Hutton and Mr. P. Marshall ; and the Order is, next to 

 the Coleoptera and the Lepidoptera, the most fully represented 

 in the region. It includes some fine and curious endemic 

 forms, the large and very rare Anthomyid, Exsul singularis 

 Hutton, from Milford Sound in the South Island, being one
