54 Psyche [March-June 
The specimens collected by Dr. Barrows at Fort Myers, 
show great variation in color among the males. Some have the 
cephalothorax pale yellow and the abdomen almost white with 
parallel stripes of gray; these have the legs about the same color 
as the cephalothorax, and either no dark stripe on the femora, 
or the stripes very indistinct. Other males are very dark, with 
the abdomen black as described by Cambridge, and the legs 
with dark lateral lines on the femora. All however, have the 
abdomen constricted just beyond the middle and a very broad 
palpus with the same corresponding parts. The females vary as 
much as the males. In some the abdominal tubercle above the 
spinnerets is reduced to a slight hump, while in others the 
tubercle is long, slender and pointed. All have the median dark 
line on the abdomen and the epigynum is the same. The color- 
ing also varies. Some are quite dark with a darker median line 
on the abdomen; others are pale with the dark median line. 
The legs are usually white. 
A lateral view of the abdomen of the female suggests some of 
the figures of Achcea given by Keyserling in the Theridiidae, 
1884, vol. 1, pi. 5.
