Psyche 
[March 
yellow with three indefinite gray spots on each side of the 
thorax, a marginal gray band and a few gray lines on the 
head part; cephalothorax rather roundly arched. Cheli- 
cerae not at all geniculate. Eyes large in proportion to size 
of spider; posterior eyes in nearly straight row, almost 
equally distant (less than a diameter of one of the eyes) and 
equal in size; eyes of anterior row very close together and 
median eyes considerably smaller than the lateral eyes. Legs 
yellow in some specimens, orange or tan ringed with gray in 
other specimens. Abdomen globose, pale grayish yellow 
with many dark gray markings especially in the posterior 
half ; these markings form a row of double concave arches 
down the center of the back posteriorly. Apical segment of 
hind spinnerets is slightly shorter than the basal segment. 
The epigynum is raised, rounded off imperceptibly into the 
venter ; in its center is a heart-shaped dark reddish brown 
chitinized area, which shows two slight impressions; these 
are the openings to the ducts leading to the spermathecae ; 
posterior to this area is a slender median dark band running 
to the epigastric furrow; this dark band is caused by the 
ducts which lead into the spermathecae, which in a few 
specimens are slightly visible as round balls underneath the 
chitin. 
Male : Length, 4. 0-4. 5 mm. Cephalothorax very evenly 
rounded with cephalic grooves very shallow, yellow in color 
with very slight gray markings. Chelicerae, and relation- 
ships between the eyes as in female ; legs about the same ex- 
cept that they are more solidly one color, yellow, or orange 
brown. Abdomen slender, white background with dark gray 
markings numerous in the posterior part, very much as in 
the female. Hind spinnerets with apical segment a little 
shorter than basal segment. Tibia of male palpus with two 
basal teeth, black in color on the lateral margins, then a deep 
horizontal groove which ends in the middle of the segment 
with a rather large black, flat projection directed anteriorly; 
on the distal margin of the tibia it bears another lateral pro- 
jection pointing anteriorly. The cymbium of the palpus is 
deeply rounded in its body part but anteriorly slenderizes 
suddenly and has a narrow, short tip. 
Hypotypes: Male specimens, collected March 24, 1932,
