CHAMBERLIN: THE ARACHNIDA. 179 
Legs and pedipalps with strongly developed longitudinal granular 
ridges. 
Hand of pedipalp broader than tibia, its ridges strongly developed, 
these continuing upon the immovable finger where they become 
smooth. Finger with fifteen or sixteen oblique lines of granules, 
(Plate 1, fig. 2); not fully twice as long as proximal hand (cir. 7: 4). 
Comb with 20-22 teeth. Basal middle lamella enlarged, Plate 1, 
fig. 4. 
Length of types 38 to 52 mm. 
Cauda of male proportionately longer and more slender than in the 
female. (Fourth segment of cauda in female 2.5 mm. wide X 5.0 mm. 
long, in male 2.5 mm. wide X 5.8 mm. long). 
Localities.— Huadquina, 5,000 feet, July 26. (Type, M. C. Z., 121; 
paratypes, M. C. Z. 122, five specimens.) Ollantaytambo 9,000 feet, 
July 20. (M. C. Z. 123, one young specimen). 
Named for Prof. H. W. Foote of Yale University. 
This species is apparently nearest to 7. bahiensis (Perty). In 
coloration it differs in having the tibia of the pedipalp light and uni- 
form, not conspicuously darkened in the way characteristic of bahien- 
sis, and in having the fifth segment of the cauda conspicuously dark. 
The hand of the pedipalp is conspicuously more slender and its ridges 
are much more strongly developed and those along the immovable 
finger continue without break to the proximal end of the hand. The 
basal middle lamella of the comb is relatively much larger, being 
more inflated, and with its inner edge semicircular instead of straight. 
The spine on under side of sting is more slender and acute with at 
most only a single and relatively small granule on its upper edge.

Plate..1,, fig, 5-8: 
General color yellow, the carapace and tergites of the preabdomen 
darkened with brown and blackish markings; carapace free from the 
darker color in a triangular area in front of eyes and in a narrower 
area behind them; tergites of preabdomen lighter along caudal border 
and in a narrow median longitudinal line; postabdomen above pale
