56 Psyche [March- June 
female can be separated from the other two, by the much sim- 
pler epigynum. The parts of the epigynum are very lightly 
chitinized in all the specimens seen but apparently are the same 
in all specimens from Cuba or from the Galapagos Islands. The 
specimen figured is from Fort Myers, Florida. 
Coleosoma normale spec. nov. 
Figures, 2, 5, 8, 10

Cephalothorax pale, with a narrow dark marginal line and 
shaded with gray posterior to eyes, rather low and flat, three- 
quarters as wide as long, anterior margin much narrowed ; eyes 
about cover anterior margin, anterior row recurved, eyes sub- 
equal, a.m.e. diurnal, separated by less than a diameter, little 
nearer to a.l.e., posterior row about straight, eyes equidistant, 
p.m.e. largest separated by more than a diameter, lateral eyes 
touching; clypeus vertical, only slightly convex, less than twice 
the eye area; mandibles pale, vertical, weak; labium pale, wider 
than long; maxillae inclined; sternum triangular, dark about 
margins; abdomen pale, with two parallel dark stripes from base 
to spinnerets, stripes quite narrow about middle and heavier at 
ends, cylindrical, about half as wide as long, no indication of a 
constriction, chitinized basal plate narrow but divided at base 
into two blunt points and extends on venter to about the mid- 
dle, venter pale yellow, margined with black, black about spin- 
nerets; legs , broken, pale, with no indications of dark stripes or 
rings, no spines; palpus about as long as cephalothorax, pale, 
terminal joint very large, broad, embolus starts from side near 
tip, follows contour to tip, forming almost a complete circle, a 
pale club-shaped piece opposite bulb rests against the large 
black conspicuous piece at tip of bulb. 
Female. Length, 1.6 mm., ceph. 0.5 mm., abd. 1.3 mm. 
Cephalothorax and legs same as in male; abdomen cylindri- 
cal, with no indication of the chitinous plate found in male, pale, 
with two widely separated parallel dark stripes from base to 
spinnerets as in male, venter with median dark gray spot that

convex chitinized plate, beneath which can be seen the convo- 
lute tubes that almost touch at anterior end and are widely 
separated at posterior.
