Psyche 
[December 
about .41 as tall as wide. Pars cephalica much less prom- 
inent than in male. The characters of the female with 
respect to eyes, chelicerae, maxillae, lip, and sternum are 
so closely similar to those of the male that a detailed de- 
scription of these parts is regarded as unnecessary. 
Legs. — 1423. Width of first patella at “knee” .08664 mm., 
tibial index of first leg 11. Width of fourth patella at 
“knee” .08123 mm., tibial index of fourth leg 11.

The calamistrum is well developed, consisting of a row of 
curved hairs on the proximal four fifths of the fourth 
metatarsus. 
Abdomen . — Essentially as in male. Cribellum well de- 
veloped, normal to the genus. 
Epigynum . — Relatively large ; convex ; with a short trans- 
verse lip near the genital groove; a small spermatheca lies 
at each end of the lip; two diverging stripes extend for- 
ward from the lip ; lateral to the anterior end of each stripe 
there is a small depression (probably an opening) ; the 
anterior end of the epigynal plate is formed by a strongly 
chitinized curved band with a central opening. Dissection 
reveals the presence of several tubules, nodules, etc. just 
internal to the surface. The convex part of the plate is 
finely and transversely rugulose (Fig. 5). 
Color in alcohol . — Almost identical with that of male 
except that the light areas on the dorsum are plainer ; here 
in the female they are two light brownish spots separated 
by a central dark stripe; in some paratype females the 
light spots are large and quite conspicuous. 
Type locality . — Male holotype from Canal Zone Bio- 
logical Area, C. Z., July, 1950; female allotype from the
