Neotype, $ Alabama; Silver Hill, July 1945, (Nelson). 
Hentz had both male and female of this species but he figures 
the female only. He states that it was found in cavites of 
limestone rocks on the margin of a river and describes it as 
rufous and hairy. The figure shows the median pale stripe on 
the dorsum much narrower than in undata , ( jamiliarius Hentz), 
found about houses. Mr. Peckham examined the specimens 
identified by Mr. Banks as rupicola from Ithaca, New York 
and Falls Church, Virginia, and found them to be only color 
varieties of undata. On examining these specimens, the epi- 
gynum proves to be the typical undata. It was Mr. Banks who 
first recognized this specimen as rupicola Hentz. 
Marpissa melanura F. O. P.-Cambridge described from a fe- 
male from Guatemala City, (Biol. Centr.-Amer., 1901, 2 : 251, 
pi. 22, fig. 7), also has excavations on the sides of the epigynum 
but the pale median stripe on the dorsum is quite broad and it 
has no indications of the pale cross bars near the spinnerets. 
This species has been placed by Peckham as a synonym of 
M. californica (Peckham).
