I have to thank Mr. W. M. Giffard for the generous gift of 

 his collections, and Messrs. O. H. Svvezey and F. W. Terry for 

 allowing me the loan of their specimens for examination. The 

 foundation of this paper has been the balance of the collections 

 made by Dr. Perkins for the "Sandwich Islands Committee." 



The following new forms have been described in this paper : 



lolania perkinsi var. notata. 



Oliarus kahavalu, kaonohi, Micicola, procellaris, pluvialis, 

 nubigenus, silvicola, montivagus, acaciae, haleakalae, monticola, 

 kaohinani, silveStris, pele, kauaiensis, paludicola> nemoricola, spp., 

 and kaonohi var. volcanicola; and orono var. molokaicnsis and 

 oahuensis. 



On a new Derbid Homopteron from New Zealand and Notes on 

 other Hemiptera. 



BY G. W. KIRKALDY. 



The genus Cenchrea was described by Westwood, as a sub 

 genus of Derbe (1841 Ann. Mag. Hist., vi, 479; and 1842 T. 

 Linn. Soc, London, xix, 15), with a single species, dorsalis, from 

 St. Vincent in the Lesser Antilles. Since then, Uhler has de- 

 scribed exquisita from the same Island (1895, P. Z. S., Lon- 

 don), and Ball has added uhleri and heidemanni from the United 

 States (1902, Can. Ent., 261). 



As the only genus of Derbidae that was known to inhabit both 

 New and Old Worlds, is Lamenia Stal (which has 9 species in 

 America, one m Tahiti— a possibly wrong habitat however — 2 

 in Queensland, and one in Larat of the Malay Archipelago), I 

 was surprised to find among some Maorian Hemiptera sent me 

 by my friends Mr. A. Hamilton (Director of the Dominion 

 Museum) and Mr. G. Howes (Govt. Entomologist), from Well- 

 ington, two examples of a species of this genus. It must be 

 noted, however, that it is very probably not endemic there. 



In his figure of C. dorsalis, (1842 Trans cit., PI. 19, f. 8), 

 Westwood has evidently incorrectly represented the pronotum, 

 which he has shown as having a truncate basal margin ; a char- 

 acter found in no Derbid, in which family it is always emargin- 

 ate, very often deeply so. 



C. maorica, sp. nov. 



The type example is pale yellowisli-brown, the frons having a large 

 inverted fuscous Y, the clypeus also partly suffused with the same 

 tint. The tegmina are bronzy yellow, the costal area and the greater
