had on hand and figured were specimens of what is here considered 
to be S. keyserlingi , and not what Keyserling called rubella. 
In the United States National Museum there is a specimen marked 
Singa rubella Hentz, St. Louis, Mo., collected by Marx. Another 
label in the vial reads “Cotype 1688 U.S.N.M.” The specimen 
contained is a female of what is here called S. eugeni , and there is 
no evidence that it is a syntype of S. keyserlingi McCook. McCook 
reports having seen specimens from the District of Columbia in the 
Marx collection. Keyserling also reports that the Singa rubella 
he examined came from the District of Columbia from the Marx 
collection. 
Figure 13 was prepared from the type of 5 . campestris.

region, clypeus black. Chelicerae, labium, endites dark brown. Ster- 
num orange. Legs orange, distal articles darker. Dorsum of abdo- 
men with two wide black bands separated by a narrow white band 
(Fig. 22). Sides of black bands have lateral white band (Fig. 21). 
Venter has a black patch which may have a white line on each side. 
Anterior median eyes slightly more than one diameter apart, one 
diameter from laterals. Posterior median eyes their radius apart, 
two and one-half diameters from laterals. Total length 5.5 mm. 
Carapace 2.4 mm long, 1.7 mm wide. First femur, 1.4 mm; patella 
and tibia, 2.1 mm; metatarsus, 1.3 mm; tarsus, 0.7 mm. Second 
patella and tibia, 1.9 mm; third, 1.3 mm; fourth, 1.7 mm. 
Male from Wisconsin. The coloration is like that of the female 
except that black on the head seems limited to the eye region. The 
chelicerae are black only distally, orange at the base. The dorsum 
of the abdomen is all black. The anterior median eyes one and one- 
third diameters apart, one diameter from laterals. Posterior median 
eyes their radius apart, two and one-half diameters from laterals. 
The palpal patella has two weak macrosetae. The first and second 
legs have strong macrosetae on prolateral surface, but are not bent 
or swollen. Total length 3.9 mm. Carapace 2.2 mm long, 1.6 mm 
wide. First femur, 1.5 mm; patella and tibia, 2.0 mm; metatarsus, 
1.4 mm; tarsus, 0.7 mm. Second patella and tibia, 1.8 mm; third, 
1.2 mm; fourth, 1.5 mm. 
Variation. In the female the scape of the epigynum varies greatly 
in length and shape (Figs. 1 1 - 1 5 ) ; the internal ducts may be either 
heavily sclerotized or transparent, sac-like and difficult to make out. 
Females vary from 5. 1-6.0 mm in total length, carapace 1 .5-1.7 mm
