 b Thirteen specimens. 



Besides averaging larger, specimens from Costa Rica and Nicaragua are somewhat 

 lighter colored than many Panama examples, which, together with Colombian ones, 

 vary in the direction of U. m. martii; still, even Colombian examples resemble the 

 latter less than they do the Costa Rican series. 



c I have not seen an Ecuadorean example of this species.
