A REVISION OF THE PISAURIDAE OF THE UNITED STATES 51 
often black; back of posterior eyes an oval area lighter, inclosed by 
a narrow, yellowish white line; a narrow, light line through the 
dorsal groove extends to the second row of eyes. Eyes of anterior 
row in a slightly recurved line, median slightly larger than lateral 
and closer to them than to each other; eyes of posterior row in a 
strongly recurved line, equal in size or nearly so, one-third larger 
than anterior; median separated by a little less than the diameter 
of one of them, somewhat more than their diameter from the lateral. 
Lower half of clypeus with a dense band of short, white hairs which 
joins the lateral bands of the cephalothorax ; width of clypeus about 
4 times the diameter of an anterior median eye. Chelicera yellow- 
ish or reddish brown, clothed with long, dark hair. Abdomen above 
varying from greenish gray to dark brown and bordered on each 
side by a broad band of white hairs more or less indistinct in alcohol ; 
on the basal half, a median, lanceolate, light stripe and two pairs 
of small, white dots; on the posterior half, four pairs of white dots 
in two widely separated lines between which are four minute, white 
dots, often obsolete or wanting in old or rubbed specimens. Legs 
above colored as cephalothorax, without distinct bands or stripes; 
below lighter; distal joints sometimes darker. Sternwm with three 
black dots on each side near the coxae. Labium and endites yellow- 
ish or reddish brown, lighter distally. Epigynwm median lobe is 
scarcely developed on the anterior half; posteriorly it separates the 
lateral lobes and terminates in a rounded hump (pl. 30, fig. 2). 
Male (alcohol): length, 13mm; legs, 4-1-2-3; 34-32-29-28mm ;

General pattern as in female but with colors often brighter and 
tending more to yellow, brown or reddish brown; spots of abdomen 
usually quite distinct and lateral light bands, bright silvery white ; 
black spots on sternum often connected to form irregular bands. 
Femur of fourth legs beneath, in adult males, with a spinose hump 
(pl. 30, fig. 4). Palpus: the extraordinary development of the tibial 
apophysis immediately distinguishes this form from all other species 
of Dolomedes; it is greatly elongated, spoon-shaped distally and is 
somewhat constricted near the base (pl. 30, fig. 1). The bulb of 
the palpus resembles closely that of D. albineus. 
The form described above must be regarded as typical and it 
apparently occurs only in the south. A dozen specimens in the 
collections of Cornell University and the State Museum exhibit 
clearly those color characters described by Walckenaer* and figured
