ZELURUS MORDAX (Breddin, 1903) 
Piats 4, Ficures 1-3 
1 9, Yurimaguas, Peru, collected by H. S. Parish in March 1920. 
The original description is quite sufficient, but in order to facilitate 
comparison we include drawings of the general aspect of the head 
(pl. 4, figs. 1 and 2), as well as of the color pattern of the species 
(fig. 3). 
ZELURUS PINTOI (Costa Lima, 1940) 
3 $4, Villa Rica, Paraguay, collected by F. Schade in October and November 
1934. 
a 
ZELURUS JURADOI (Costa Lima, 1940) 
Prate 4, Ficures 4-7 
1 2, Tumupasa, Bolivia, collected by W. M. Mann in December 1921 (Mulford 
Biological Exploration 1921-1922). 
The specimen at hand corresponds quite well with the original 
description. We herewith supplement the diagnosis by including 
drawings of the general aspect of the head as well as of the clasper 
and the aedeagus; the form of the basal sclerite of the phallosome is 
significant.
