When we compare the Samoan with the Fijian fulgorids 

 a strong relationship is revealed. So far as we know at 

 present the Samoan fulgorid fauna is a poor representation 

 of the Fijian, which in turn is a poor representation of the 

 Malayan and Philippine. 



Hitherto the Malay Archipelago has been considered with 

 little reference to the Philippines, but as the latter is the 

 richest part of the Malays, so far as insects are concerned, 

 it will be necessary in future to reconsider many conclusions 

 as to dispersal in the light of recent work in the Philippines. 

 It is to be hoped that the outlying islands of the Polynesian 

 plateau will be thoroughly worked in the near future so that 

 we may be able to trace the line of migration of many of 

 these insects. 



Samoa, judging by the fulgorids of Tutuila, is an outpost 

 of the Polynesian plateau and derived its fulgorids from 

 that region. It is not necessary to join it up to that region 

 by land to account for their presence, as I think they could 

 have arrived by natural means of transport across a moderately 

 wide expanse of water. In some cases, such as Perklnsiella in 

 Niiie, man may have been the agency. 



The genitalia of most of the families of Fulgoroidea have 

 not been studied, or only in a very superficial manner. I 

 believe that detailed studies will lead to a better understanding 

 of the relationship of the families. Some interesting forms 

 are found among this small collection revealing complexities 

 quite unexpected. 



The types have all been deposited in the collection of the 

 Hawaiian Sugar Planters' Experiment Station, Honolulu, and 

 numbered with the type number of that collection. The 

 measurements are from apex of vertex to apex of abdomen 

 and from the base to apex of one tegmen. 



ClXIIDAE. 



Myndus roggeweini sp. n. Fig. 6. 



Male. Length 2.8 mm., tegmen 3.4 mm. Vertex considerably longer 



than width at base, which is broader than apex; a faint transverse carina 



about middle; length of face equal to width, widest at apical third; 

 median ocellus distinct.
