Namopsilus gen. nov. 
Cephalothorax with general form much as in Trachelas. Sternum broadly trun- 
cate anteriorly, pointed at caudal end, margined. Endites not excavated exteriorly, as 
broad at middle as at distal end; the distoectal corner rounded. Labium distally 
truncate or a little incurved. Lateral eyes on each side well separated, though much 
closer together than the anterior and posterior medians. Anterior row of eyes straight. 
Anterior medians smaller than the laterals. Posterior row of eyes slightly recurved, 
eyes equidistant or nearly so and nearly equal in size, with the laterals equal to the 
posterior laterals. Quadrangle of median eyes wider behind than in front. Clypeus 
much wider than the anterior eyes. Upper margin of furrow of chelicera with three 
large teeth, of which the median is longest; lower margin with a series of seven or 
eight teeth, of which the most proximal ones become reduced in size. None of the legs 
scopulate and all lacking terminal tenent hairs. Anterior tibie armed beneath with 
four pairs of long spines, the metatarsi with three pairs. Posterior tibie in middorsal 
line with a basal and a subapical spine, and each patella with a median spine at 
distal end above, these dorsal spines smaller than the laterals and ventrals. 
Genotype—wN. pletus sp. nov. 
Namopsilus pletus sp. nov. 
Female—Carapace chestnut colored, dusky over the sides, eye region, along strie 
and over clypeus. Legs light chestnut-brown; femora marked with two wide dark 
annuli, one at distal end and one submedian, these more or less interrupted above; 
patella with annulus about distal half also interrupted above; tibia with two broad 
annuli, one at distal end and one between middle and base, these sometimes almost 
confluent; entire metatarsi dusky or obscurely biannulate. Sternum light chestnut, the 
coxe of legs lighter brown. Chelicere dusky chsetnut. Labium and endites pale across 
tips, elsewher edark chestnut. Sides of abdomen deep brown or blackish, the dorsum 
with a series of dark chevron marks ending in the dark of the sides and connected 
along the middorsal line, the spaces between them on each side yellowish; venter 
grey. Clypeus twice as high as the diameter of an anterior lateral eye. Anterior 
median eyes much smaller than the laterals, about their diameter from each lateral eye 
and considerably farther from each other. Lateral eyes on each side about their radius 
apart. Posterior row of eyes a little recurved. Posterior median eyes scarcely smaller 
than the laterals, nearly once and a half their diameter apart and an equal distance 
from the laterals. Epigynum as shown in pl. 6 f. 1. The spermathece, which ordi- 
narily show through the integument as black bodies, are not represented in the figure.

LYCOSID 
Lycosa ferriculosa sp. nov. 
Carapace brown, paler in a supramarginal line on each side, below which the 
marginal dark band is interrupted, and in a median longitudinal stripe which narrows 
forward and projects in a point between the eyes and again expands between the first 
and second rows; a curved line each side of the median stripe just caudad of the eyes.
