Phyllodinus koebelei (Kirk.). 



Phacalastor koebelei Kirk. (1906) Bull. H. S. P. A., Knt. 

 I, p. 408. 



Dicranoiropis koebelei (Kirk.) (1909) t. c. III. p. 134. 



Twenty-eight brachypteroiis specimens, April, 1918. and one 

 macropterous specimen. Jwne, 1918 (Kellers), from Tutuila, 

 Samoa. The front legs of this species are distinctly flattened 

 and slightly expanded and so must come into the composite 

 genus Phyllodinus Van D. as it stands at present. 



Perkinsiella vitiensis Kirk. 



Five specimens from Savage Island (Xiiie). (Kellers, 

 August 6, 1918.) 



Hitherto this species has only been known from Fiji. As 

 this species is attached to sugar cane and this plant was 

 carried by the natives in their early migrations, the distribution 

 of the insect in the south Pacific would be of interest and 

 might throw some light on the migration of the Polynesians. 

 This applies to many insects attached to economic plants 

 carried by the natives on their voyages. 



Sardia pluto Kirk. 



One specimen from Tutuila. Samoa. (Kellers, December, 

 1918), 12(X) feet elevation. Previously known from Australia, 

 Fiji, Formosa and Philippine Islands. 



Megamelus proserpina Kirk. 



One female specimen from Savage Island (Kellers, August 

 6, 1918). Previously known from Fiji, Amboina, Java and 

 the Philippine Islands.
