Psyche 
[September 
of this species examined bearing this name are those of Taczanowski 
in the Polish Academy of Sciences, Warsaw. The Franganillo names 
may refer to this species or E. ravilla. 
Description. Female from Panama Canal Zone. Carapace, ster- 
num, and legs brown. Carapace with some long white hairs from 
thoracic groove toward sides of head and shorter ones on the anterior 
margin. Dorsum of abdomen black with a well defined narrow 
longitudinal white line. Area on venter between epigynum and 
spinnerets with a triangular black mark pointing posteriorly, and a 
white pigment spot on each side anterior of the spinnerets (Fig. 31). 
The dorsum of abdomen is sparsely covered by long white hairs. 
The anterior median eyes are largest, the posterior medians about 
0.8 diameters of anterior medians, laterals about 0.7 diameters. The 
anterior median eyes are a little more than one diameter apart, the 
posterior medians about two-thirds diameters apart. The abdomen 
is subtriangular, rather high above spinnerets. Total length, 18 mm. 
Carapace 8.3 mm long, 6.8 mm wide. First femur, 10.0 mm; petella 
and tibia, 12.3 mm; metatarsus, 8.7 mm; tarsus, 2.6 mm. Second 
patella and tibia, 12.4 mm; third, 6.7 mm; fourth, 10.5 mm. 
Male from Panama Canal Zone. Coloration like that of female 
but lighter. Sternum light brown. Distal segments of legs light 
with some dark spots at origin of setae. The carapace has a deep 
longitudinal thoracic groove with two short posteriorly directed 
branches. The anterior median eyes are largest, the posterior medians 
0.7 diameters of anterior medians, the anterior laterals 0.6 diameters 
and the posterior laterals 0.5 diameters of anterior median eyes. The 
anterior median eyes are one and one-half diameters apart, the 
posterior medians about two-thirds their diameter apart. Total 
length, 14 mm. Carapace 7.2 mm long, 6.0 mm wide. First femur, 
8.0 mm; patella and tibia, 10.5 mm; metatarsus, 7.8 mm; tarsus, 
2.2 mm. Second patella and tibia, 9.6 mm; third, 5.5 mm; fourth, 
8.0 mm. 
Variation. The total length of the female varies between 14-30 
mm. The total length of adult males 12-16 mm. The largest come 
from the northern Amazon region. The dorsal white line on the 
abdomen may be absent. The dorsum sometimes has white patches 
instead of a line and sometimes the sides of the abdomen have white 
pigment patches. Most specimens, however, do have the longitudinal 
line. Some females have a dorsal posterior hump on the abdomen 
as large as that of E. edax. The length of the scape of the epigynum
