Mexico : one {Salle), Mus. D. Cr. E. 



Vera Paz, Guatemala : four, Mus. D. G. E. Choctun, Vera 

 Paz : three (Salv. fy Godm.), Mus. S. & G. Vera Paz : one 

 (Salv.), Mus. P. L. S.

Costa Rica : two (Carmiol fy Endres), Mus. S.&G. 



Bugaba, Chiriqui: one (Arce), Mus. S. & G. 



Lion-Hill Station, Isth. Panama: four (McLeannan) , Mus. 

 S. & G. ; one (id.), Mus. P. L. S.
