CHAMBERLIN : THE ARACHNIDA. 189 



ously granular, the end portions smooth; caudal border with a trans- 

 verse row of tubercles; the area between fifth and fourth sulci with a 

 transverse row of fewer and less developed tubercles, the two areas 

 next cephalad with still fewer and more obscure tubercles similarly in 

 a transverse line, (Plate 5, fig. 1). 



The first two abdominal segments each bearing above a transverse 

 row of numerous, well-developed granules. Dorsal anal scutum 

 bearing five conspicuous spinous processes of which the median is 

 much longest, and in front of the most anterior of these on each side 

 a series of much smaller teeth which decrease progressively cephalad; 

 the second spine from the median one on each side is elevated dorsally 

 along its whole length in a keel-like form, the elevated portion pro- 

 jecting cephalad over base in a rounded, tubercle-like process. 



First three pairs of coxae proximally parallel, those of the first two 

 pairs distally curved considerably cephalad, the third ones straight 

 throughout. Second coxae but little more than one fifth longer than 

 the third (15:11). The coxae of the second and third pairs along 

 anteroventral surface with a low, sharply elevated edge which is 

 obscurely tuberculate; first coxae with no elevated edge but wnth a 

 row of very small tubercles. Fourth coxae very strongly enlarged as 

 usual and directed caudad; each one terminating at distal end on 

 ectal side above in a stout acute spine and on opposite mesal side of 

 end in a similar but smaller spine; elsewhere smooth, not tuberculate 

 or dentate. 



Spiracles distinct, rather large. 



]Mandil)les stout; first article strongly narrowed proximally, the 

 expanded distal portion with a strongly elevated, long, keel-like 

 hump above which is smooth ; second article in front sparsely clothed 

 with hairs and with fewer hairs behind toward distal end, (Plate 5, 

 fig. 2). 



Pedipalps rather short, when extended scarcely as long as carapace ; 

 not crossed. Trochanter short, . subcylindrical, with a low hump 

 above on which are one or two slight tubercles; ventrally with a few 

 hairs springing from slightly tubercular bases. Femur cylindrical, 

 not compressed, moderately convexly elevated from end to end 

 above; wholly without spines; a few short hairs from slightly tuber- 

 cular bases below. Patella unarmed. Tibia not compressed; along 

 mesoventral edge with two rather slender, acutely acuminate spines 

 and between these a minute third one; along ecto ventral edge with 

 three long spines and between the caudal and middle one of these a 

 fourth minute one; the middle one of the larger spines much largest
