Colorado Island, Canal Zone, Feb. 22, 1924 (W. M. Wheeler). 
The last two are males. 
The variety vagans may be distinguished from the typical 
P. brasiliensis first by the tendency for pairs of the transverse 
integumentary folds to fuse above the base of the legs on the 
posterior part of the body, a condition that has not been found 
in the typical form where the rare cases of fusion or incomplete 
folds are irrespective of the bodily segmentation. It differs also 
in the much greater development of the accessory papillae which 
approach the condition found in P. imthurmi. The latter form 
has however, incomplete folds regularly on each segment.
