Remarks. The bright ochraceous or almost ochraceous buff color 
of this species combined with its small size distinguish it from the other 
forms of northern South America. Its closest relationship is perhaps 
with P. guaire but it is readily distinguished by its paler color, nearly 
pure white hind feet, and its small size. P. cherriei of the upper Ori- 
noco evidently approaches it in size but is much darker in color. Prac- 
tically all the other described forms are much larger. 
Our specimens were trapped about the roots of the wild pineapple, 
locally known as maya and very abundant in the arid parts of the 
northeast shore of Lake Maracaibo.
