Frauenfeld queries as to who "Whit." is. The fact that Pal. euiarginata 

 and other North American species are in the Cuming Collection named by 

 "Whit." makes it a possibility that this is also an American species. It is 

 possible that "Whit." stands for T. J. Whittemore, who was a well known 

 collector in ^lassachusetts in 1840.
