CHAMBERLIN: THE ARACHNIDA. 191 
COSMETIDAE. 
PARAVANONES PERUVIANUS, sp. nov. 
Plate 2, fig. 1-6. 
General background of body a dilute ferruginous. Carapace 
dusky from a close network of black lines, the color less dusky in a 
deltoid area back of eye-tubercle with apex caudad and embracing 
two short black stripes, one caudad of each eye, in a narrow mid- 
longitudinal line, and along the transverse sutures and in a broader | 
area along each side of the carapace, tubercles pale. Ventral surface 
of cephalothorax and coxae paler, a clearer light ferruginous; under 
lens seen to be covered with a less dense network of dark lines. Ab- 
dominal segments both above and below black or nearly so, a line 
back of each segment white. Legs also with an inconspicuous net- 
work of fine dark lines; femora, patellae, and tibiae dark at distal ends 
and tarsus of leg I also blackish. 
Carapace widest at level of third sulcus, convexly rounded, abruptly 
narrowed a little in front of caudal end and at level of caudal edge of 
third legs in front of which the sides converge but moderately, the 
anterior corners more oblique. 
Carapace crossed by five transverse furrows which are wide, not 
suture like, and of which the first is bent back angularly at the middle. 
Eye-tubercle much wider than long, concavely depressed from ends 
toward middle; a series of four tubercles in a curved line on each 
elevated end subparallel with edge of ocellus and several weaker 
tubercles immediately mesad of these; the median portion of eye- 
tubercle smooth. Anterior margin not elevated or only obscurely 
so on each side, the median portion between eye-tubercle and front 
margin broadly elevated. At each anterolateral corner a prominent 
process, (Plate 2, fig. 3), the border near level of anterior edge of second 
coxae with a process projecting caudoventrad and meeting a process 
from second coxae.~_ Edges of carapace in its widest part with a 
number of rather low conical tubercles, the tubercles across caudal 
border more numerous and with two much larger subcylindrical 
processes near middle; the more anterior lateral margins essentially 
smooth. On areas between furrows a limited number of tubercles 
which are larger and somewhat more numerous in caudal than in 
anterior region, and in each area a pair of tubercles which are higher
