Plate 2, fig. 7-8; Plate 3, fig. 1-5. 



Main portion of carapace very dilute ferruginous, its caudal and 

 caudolateral borders dusk\' but integument along edge of these parts 

 white; area in front of cervical furrow deeply mottled with black; 

 tergite of abdomen blackish with caudal border lighter. Legs black, 

 but the distal articles of tarsus III conspicuously light, whitish, and 

 the metatarsus and especially the tarsus of leg IV also somewhat 

 lighter. Coxa IV dilute ferruginous black across distal end both 

 below and above excepting the white line along the edge, its process 

 also black excepting the paler tips. Coxae of legs I to III densely 

 mottled with black excepting niesal ends which are paler. Sternites 

 of abdomen blackish excepting the paler caudal borders and the white 

 integument adjoining the caudal edges. 



Body very wide toward caudal end of cephidothorax from where 

 very stronglj' and abruptly narrowed cephalad to opposite bases of 

 thirfl legs, then more gently narrowing to anterior end; also con- 

 spicuousl}^ narrowing caudad to end of abdomen; the greatest width 

 of carapace ecfual to body length, (Plate 2, fig. 7). 



Carapace with only four complete transverse sulci, but the first of 

 these with two branches on each side; first sulcus lying in a deeper 

 cer\ical furrow, as usual angularly bent caudad at middle; second 

 sulcus moderately angularly bent forward at middle; third sulcus 

 with ends bent abruptly caudad and then running sul)parallel with 

 body axis; fourth sulcus angularly bent forward at middle; all sulcj 

 connected by a median longitudinal sulcus which is deepest between 

 the first two. Eye-tubercle sharply set off and elevated, wider than 

 long, the two cones near its caudal border not especially high. An- 

 terior border of carapace conspicuously elevated as usual, the elevated 

 rim much widest at middle. Lower frontal margin extended lietween 

 the notches for mandibles and laterad of each in an acute spine-like
