Palpi. — Rather sliort, coiicoloi'ous witli legs, liaiiy, femur 

 bowed, broadest at apex, wliere it is armed vvitli tliree strong, 

 moderate!}^ long spines, and tliree short, weak ones ; patella 

 broadest at apex also, where it is armed Avith two strong, 

 moderately long spines, and two short, weak ones ; tibia armed 

 on its upper surface with four short, stout spines, on tlie inner 

 angle witli eight long, strong spines, and at the apex with 

 several short ones ; radial joint short, densely hairy ; genital 

 bulb pear-shaped, broadly cleft at apex ; style rather broad, 

 long, twisted, terminal extremity flattened like a spatula. 



Falces. — Coucolorous with cephalothorax, 



moderately long, porrected, powerful ; ujjper | 



surface from base to apex, densely hairy ; • ^ ^ 



sides smooth, but having a narrow row or line • • 



of seta? running down the middle ; in addition • .' • 



to these latter there are, towards the lower \'- m 



angle, a quantity of very short, scattered •'• •

strong as the former; there is also a some- Scheme of dentition, 

 what sinuous and irregular intermediate row 

 consisting of fourteen small teeth (fig. &Q) ; outer angles fringed 

 with red hairs ; faii^s long, well curved, nearly black. 



Ma.riJI(e. — Reddish-brown, divergent, arched, inner angles 

 acuminate, surface moderately hairy ; at the base of each 

 maxilla there are a lai-ge number of very small toothlike spines, 

 which latter impart a granulated appearance at that point ; 

 base curving gently n)und the labium, and terminating with a 

 somewhat heel-like projection ; inner angles fringed with long, 

 red hairs. 



Labium. — Coucolorous, arched, short, broad, rounded at apex, 

 thickly studded with short, toothlike spines, similar to those 

 on maxillge ; apex, sides, and base thinly clothed with rather 

 long hairs. 



Sfenium. — Coucolorous also; rather flat, narrowest in front, 

 where it is deeply excavated to receive base of labium, broadest 

 at a point between third and fourth pairs of coxse, base rounded
