the male palpus, and apparently no males were in the collections 
which he examined. Bishop used the pattern as a distinguishing char- 
acter, but, although valid, it appears to fit well into the range of 
variation of P. mira and therefore seemed rather dubious. He also 
failed to take note of one of Emerton’s original characters, the com- 
parative lengths of the leg I and body, which when converted to a 
ratio between the patella-tibia and carapace length, proves to be 
statistically valid. 
Only three males are known to exist in collections and are in the 
Exline-Peck collection, Ohio State University museum, and the 
American Museum of Natural History.

Diagnosis. This species is easily distinguished from P. mira and 
P. brevipes by the strongly recurved anterior eye row while the latter 
two species have the eye row straight or nearly so. Pisaurina un- 
dulata differs from P. dubia because in the former species the width 
of the PME exceeds 1.5 the width of the ALE, while in the latter 
species the ratio is less than 1.5. Additionally, of the two latter spe- 
cies, only P. dubia has a triangular group of white hairs projecting 
forward from the area between the AME. However, P. undulata 
has rows of prominent curved spines in the eye region. The genitalia 
of the latter also differ. 
Description. Carapace: wider than abdomen; depressed; rows of 
curved spines behind AME and on side of clypeus. Eyes: anterior 
row strongly recurved ; ALE near margin of clypeus and prominently 
tuberculate. Legs: i-(4-2)-3. Abdomen: long, cylindrical, tapering 
posteriorly, often curved downward. Pattern: variable; carapace 
with distinct median line, alternating light, dark longitudinal bands; 
abdomen with median band varying to scattered dark spots on light 
background. (Figs. 9, 10). male. Cymbium moderately broad; con- 
ductor expanded distally with a spine retrolaterally ; median apophy- 
sis bifid; embolus quite long, thin, arises proximally. (Fig. 15) fe-
