Supplementary Notes. 



Since writing the above I have been enabled to read Distant's Synonymic 

 Catalogue of Homoptera, pt. 1, Cicadidae (B.M.N.H., 1906), from which 

 most of my synonymy was obtained through Mr. H. Ashton, of Sydney. 

 The list includes, however, several items which need incorporating in the 

 revision. It appears that, in the main, all Distant's conclusions are corro- 

 borated by New Zealand experience of the insects and of their bionomics. 

 It should be noticed that M. arche Walk, is not synonymous with the 

 New Zealand M. scutellaris Walk., as Kirby maintained. This conclusion of 

 Distant therefore proves the endemicity of M. scutellaris, which had been 

 impugned by Kirby 's contention. 



Melampsalta strepilans Kirk. — Reasons for following Kirkaldy in elevat- 

 ing M. cingulata var. obscura Huds. to the rank of a species under this 

 name I have given at considerable length.
