CHAMBERLIN: THE ARACHNIDA. 214 
AUXIMUS PRODUCTUS, sp. NOV. 
Plate 8, fig. 5-7. 
Carapace dusky brown or fuscous. Caelicerae similarly dusky 
over a more reddish or chestnut background. Legs testaceous; 
the tibiae, tarsi, and metatarsi of legs I and II dusky, almost black or 
tibia with an apical and a broader subbasal dark annulus indistinctly 
set off; tibiae of legs III and IV with apical and subbasal dusky annu- 
lus distinct and metatarsus of these legs with an apical and a broader, 
less distinctly limited subbasal dark band. Patellae dusky. Femora 
without rings or distinct marks, usually dusky beneath proximally. 
Tibia and tarsus of palpus dusky or almost black like the distal articles 
of anterior legs. Sternum dusky brown. Labium and endites darker 
than sternum, pale across tips. Abdomen above with background 
of greyish yellow of slight olivaceous tinge; at base above with a 
black median sagittate stripe the acute apex of which is at middle; 
this mark is followed caudad by a series of four, successively smaller 
and smaller chevron-shaped black lines the angle of the first of which 
is at the point of the sagittate mark; chevron marks with ends on 
each side united by a longitudinal black line. Dorsum elsewhere with 
small black, in part angular, dots, these more numerous on the sides 
where they are confluent with enclosed areas dusky and entire surface 
thus appearing blackish. A broad median band along venter immacu- 
late greyish yellow of slight olivaceous cast like background of dorsum. 
Posterior row of eyes considerably procurved, a line through middles 
of median eyes being nearly tangent to caudal edges of laterals; 
median eyes clearly less than twice their diameter apart (11:7) and 
nearly the same distance from the laterals; smaller than the laterals 
(7:9). Anterior row of eyes with line of apices as seen from above 
very slightly procurved; viewed from in front the row is nearly 
straight, the centres of the laterals being slightly lower; median eyes 
with diameter half as great as that of laterals, four fifths their diameter 
apart, nearly same distance or slightly farther from laterals. Ante- 
rior laterals equal to posterior laterals from which they are separated 
by a distance not more than equalling half the radius. 
Labium about two thirds as broad at base as long; narrowed distad; 
apically truncate. 
Sternum longer than wide, the length inclusive of caudal process 
being to width as 9: 6.5 and the length only to level of anterior proximal 
corner of coxa IV being as 7:6.5.
