CHAMBERLIN: THE ARACHNIDA. oh 
median dorsal accent shaped black stripe with point cephalad and 
base at middle; enclosing dorsal area is a dark band of elliptical form 
with a cross connection toward caudal end, also united with anterior 
band along middle line, and a network of finer dark lines connecting 
with the median dark mark elsewhere within the ellipse. 
Posterior row of eyes a little recurved; a little longer than the ante- 
rior row; median eyes farther from each other than from the laterals; 
laterals equal to the medians. Anterior row of eyes in dorsal view 
recurved in such degree that a line tangent to anterior edges of laterals 
passes through the posterior fourth of medians; in anterior view the 
row is straight; median eyes but little smaller than the laterals, near 
their diameter apart and three fourths as far from the laterals. Area 
of median eyes somewhat trapeziform, the width anteriorly being less 
than that posteriorly in about ratio 5:6. Anterior lateral eyes their 
diameter from lower edge of clypeus. 
Epigynum with openings widely separated, protected by laminae, 
(Plate 8, fig. 8). 
Sternum much longer than wide (18:13). 
Cribellum undivided as in most species.

Locality.— San Miguel 6,000 feet, July. (Type, M. C. Z. 162, one 
female). 
Four species, all based similarly upon females, have been previously 
described from Peru. The present species is most readily separated 
from these and other South American species through the different 
form of the epigynum, the eye relations, and the coloration. 
SCYTOTIDAE. 
LOXOSCELES RUFESCENS (Dufour). 
Scytodes rufescens Dufour, Ann. gén. sci. phys., 1820, 4, p. 203, pl. 77, f. 5. 
Numerous specimens of both sexes were taken at Huadquina in 
July and August, 5,000 feet. (M. C. Z. 163, 164). This species is 
widespread in both hemispheres.
