.Southern Mexico, in States of Vera Cruz (Jalapa, Jico, San Andres 

 Tuxtla), Puebla (Huehuetlan, Atlixco), Mexico (valley of Mexico), 

 Morelos (Yautepec), Sinaloa (Mazatlan, Presidio), Jalisco (Ixtapa), 

 Colima, Oaxaca, and Chiapas (Chicharras, Ocuilapa), and Territor}' of 

 Tepic (Santiago), southward through Central America to western and 

 central Ecuador, Guiana, Trinidad, and Tobago; island of Grenada, 

 Lesser Antilles. 



'Seven specimens. 



Average measurements of specimens from different localities are as follows: 



Two adult females and an immature male from Yautepec, Morelos, and an imma- 

 ture male from Colima, Jalisco, are altogether paler in color of the upper parts than 

 specimens from other parts of Mexico, which, in coloration, are precisely like those 

 from Central America and northern South America. The upper parts are light 

 brown (intermediate between broccoli brown and Isabella color),- but the under 

 parts are not differently colored from those of more eastern and southern localities.. 

 Whether these specimens indicate a different form for western Mexico can only be 

 determined by examination of adequate material.
