148 TRANSACTIONS OF THE [1892 



I liave examined specimens from varions parts of 

 Mexico, and from Gfuatemala, Panama, Gruiana, and Matto 

 Grrosso, Brazil. Specimens from Tamaulipas, Mexico, differ 

 in no respect from others living farther South, although 

 the species is a very variable one, especially in the 

 amount and form of black marking on the upper surface 

 of the body. The region of the E,io Grrande of Texas is 

 the most northern limit of this species, while the north- 

 ern part of the Argentine Republic seems to be its most 

 southern habitat. By including Trinidad in the Antilles, 

 Mr. Distant unites the West Indian Fauna with the 

 South American, but as this species has not been found 

 to inhabit the true Antilles, such as Jamaica, Cuba, San 

 Domingo or Porto Pico, we are not justified in referring 

 it to the Antillean region, which has other forms pecu- 

 liarly its own.

Specimens have been sent to me which were collected 

 near Cordova and Orizaba, Mexico ; and I have examined 

 others from G-uatemala and Brazil. A soiled specimen 

 from Southern Texas seems to belong to this species.
