The distribution of this species is throughout the Austroriparian region 

 of the Nearctic fauna. The distance to which it ascends the Mississippi 

 is as j'Ct unknown. A color variety occurs in Sonora, according to 

 the record of the U. S. IS^ational Museum (Cat. !No. C067), which is 

 distinguished by the small size of its dorsal spots. They are two scales 

 long and three wide anteriorly, and one long and seven wide poste- 

 riorly, becoming thus transverse. They are widely separated.
