This series shows that considerable variation is present in the 

 intensity of the base color of the body and limbs, this being rather 

 warm brown in some and decidedly olive green in others. The femoral 

 bars are less distinct in some specimens than in others, due in the 

 poorly contrasted specimens to a suffusion of the light bars with olive 

 green. One specimen is washed with rosy red, a condition previously 

 noted in species of this genus by Pictet and Saussure.
