182 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
as usual, the ridge largely composed of a continuous row of tubercles 
which, large behind, decrease cephalad and disappear caudad of level 
of first sulcus, the row of tubercles continued also across caudal 
border. A row of two or three tubercles in a second low ridge occurs 
just mesad of the outer rim a little caudad of widest part of carapace. 
The cones, immediately in front of last sulcus and near middle line, 
are rather low, distally rounded. Area between last two sulci with 
numerous larger and smaller tubercles or granules, the area between 
the second and third with fewer and mostly very small granules and 
the area between the first and second with still fewer scattered and 
inconspicuous granules, (Plate 2, fig. 7). 
First three tergites of abdomen with a continuous transverse row of 
conspicuous tubercles. Anal scutum without processes; rather ob- 
securely granular. 
First three pairs of coxae proximally parallel, the first two bending 
moderately cephalad from near middle of length, the third transverse 
for whole length; second coxae scarcely one fifth longer than the third; 
first coxae along midventral surface with a row of distinct granules, 
the second with a few almost obsolete granules and the third smooth. 
Fourth coxae very strongly enlarged and directed ectocaudad as usual; 
terminating on dorsoectal side in a stout process which has a shorter 
prong on the ventral side beyond middle of length; on mesal side of 
distal end with a shorter stout process which is toothed on its ectal 
side. 
Spiracles moderate, distinct. 
First article of mandibles strongly narrowed toward base; distal 
half with a strongly and abruptly elevated hump on dorsal surface. 
Distal article with fewer hairs in front and distad, (Plate 2, fig. 8). 
Pedipalps when extended shorter than carapace; not crossed. 
Trochanter roundly elevated and smooth above; ventrally with a 
single conical tubercle bearing distally a bristle. Femur a little 
complanate beneath and bearing few low granules from which hairs 
arise; dorsally also with scattered low granule-like elevations at bases 
of some of hairs. Patella smooth. Tibia not compressed; along 
mesoventral edge with two similar but stouter spines with proximal 
portions thicker as usual. Tarsus along mesoventral edge with two 
subequal spines of usual type and along ectoventral edge with two 
similar large spines and between these a much smaller spine and a 
similar one between the distal large spine and the base of the claw. 
Claw much shorter than tarsus, conspicuously curved, (Plate 3, fig. 
1, 2).
