Australian Cicadidae. 107" 



In all Museums. Hab. — Queensland, New South Wales. 



I do not feel at all sure that T. doddi, God. and Frog., is not 

 entitled to specific rank. This species is without the three dis- 

 tinct infuscations of the tegmina which give the name to Germar's- 

 species. Correlated with this feature is the considerably larger- 

 size. I have seen many large ranges of both these Cicadas. The- 

 two exist in the same localities, without any intermediate forms 

 to link them. At all events, I certainly must regard T. doddi as a 

 distinct variety.

Genera of Doubtful Habitat. 



Goding and Froggatt include Tympanoterpes hilaris, Germ., 

 Huechys vidua, and Gaeana maculata, Drury, amongst the Aus- 

 tralian Cicadas. I do not know their authority for the first, and 

 the authority for G. maculata is one specimen out of three in the 

 South Australian Museum, Adelaide, labelled :" Northern Terri- 

 tory." It may be Australian, but that evidence is not good 

 enough. I have T. (Proarua) hilaris from S. America, and G.. 

 maculata from China. I certainly cannot consider them as Aus- 

 tralian on the available evidence.
