Kirkaldy has proposed the name Alchisme for this genus (En- 

 tomologist, 1904, 37, p. 279) to take the place of the preoccupied 

 genus Triquetra. It would seem at present a rather unnecessary 

 multiplication of genera to raise Stal's subgenus Microschcma to 



generic rank.

I believe the above to be the correct synonymy of this species 

 which is the type of Amyot and Serville's genus Ceresa and has had 

 an interesting history in the literature of the Membracidae. It is ap- 

 parently abundant throughout South America and extends in its 

 range as far north as Mexico.
