mens considered under S. mimus could well constitute more than 
one species. It is now apparent that at least three species were rep- 
resented. Diagnostic measurements of S. mimus and the report on 
the number of cheliceral teeth in 1962 should be disregarded. The 
color description and pattern illustrated were of the type female of 
S. mimus and remain valid. 
Measurements : Total body length of two males from the type 
locality 11.5, 11.9 mm. Carapace width 4.3, 4.4 mm, carapace 
length 5.7, 5.9 mm. 
Width of anterior eye row 1.05, 1.25 mm. Posterior ocular 
quadrangle: PME width 1.10 mm, PLE width 1.58 mm, POQ 
length 1 .00 mm. 
Leg IV: femur 6.1, 6.2 mm, patella-tibia 7.6, 7.8 mm, meta- 
tarsus 7.2, 7.4 mm, tarsus 3.4, 3.5 mm, total length 24.3, 24.9 mm. 
Patella-tibiae: I 6.8, 7.2 mm, II 6.5, 6.9 mm, III 5.8, 6.0 mm. 
Total body length of 10 females from the type locality 12.5-18.2 
mm, mean 14.93 mm. Carapace width 4.3-5. 6 mm, mean 4.91 mm, 
carapace length 5. 7-7. 7 mm, mean 6.71 mm. 
Width of anterior eye row 1.38-1.70 mm, mean 1.535 mm. Pos- 
terior ocular quadrangle: PME width 1.18-1.43 mm, mean 1.278 
mm, PLE width 1.75-2.18 mm, mean 1.920 mm, POQ length 1.05- 
1.28 mm, mean 1.163 mm.

8.3 mm, mean 7.36 mm, metatarsus 5. 6-7. 2 mm, mean 6.44 mm, 
tarsus 2. 7-3. 5 mm, mean 3.13 mm, total length 20.0-25.7 mm, 
mean 23.15 mm. 
Patella-tibiae: I 5. 7-7. 5 mm, mean 6.57 mm, II 5. 3-6. 8 mm, 
mean 6.19 mm, III 4. 5-6.2 mm, mean 5.42 mm. 
Diagnosis. Sosippus mimus is like S. texanus in color pattern 
and number of posterior cheliceral teeth. It is distinguished from 
S. texanus by the structure of the female epigynum (compare Figs. 
1-9 with figs. 21, 22 of Brady, 1962). Specimens of S. texanus are 
larger in average size. 
Sossippus mimus is easily separated from S. floridanus by the num- 
ber of posterior cheliceral teeth (Table 1), color pattern (compare 
Figs. 28-33 with Figs. 34-38), and epigynal structure (compare 
Figs. 1-9 with Figs. 10-13, 19-24). 
Natural History. Sosippus mimus was collected from regions of 
sandy soil in wooded areas and in more or less open fields from 
eastern Louisiana to western Florida from 17-20 June, 1968. Like 
other species of Sosippus it occurred commonly in disturbed habitats, 
for example, fields that had been cleared for construction, fire breaks,
