 Cicadidae from Madagascar. By W. L. Distant. . 



[Read June 7th, 1882.] 



Plate XV. 



The more we see of the Ehynclibtal fauna of Madagascar 

 the greater is the amount of structural speciahsation 

 apparent, and its distinct character revealed. This is 

 particularly the case with the Cicadidae, and every species 

 of the widely distributed Genus Platypleura which has 

 yet been received from Madagascar has proved new to 

 Science. I have added the description of another 

 species here, and also of a new genus possessing an 

 inflated abdomen, a character found in genera distributed 

 in South Africa, Australia, and Polynesia.
