« Twelve specimens. 



''Three specimens. 



Specimens from Guatemala and southward are smaller than tliose from Chiapas, 

 and, as a rule, are appreciably less distinctly blue in the color of the back, etc.; but 

 without a much larger series I am unable to determine whether the differences are 

 sufficiently obvious or constant to justify further subdivision of the species. Average 

 measurements according to localitv are as follows:
