Pison Icetus Sm. and Pison Jlavipictus Sm., both collected by 

 Bates on the Upper Amazon, belong, according to my determin- 

 ation, to the genns Scapheutes Handl., but the types appear to 

 be lost or have not been marked. Pison jnlosus Sm. belongs to 

 the genus Pisonojjsis. Smith evidently discovered his error as 

 to the first two. for they are omitted from his list of the genus 

 in 1869.

I have only seen P. pilosus Sm., and therefore can give no key 

 to the species. 



The genus is entirely American, and will probaUy prove to be 

 nearly as rich in species on that continent as true Pison.
