[Feb., 



caudal femora, moderately robust, somewhat arcuate proximad and 

 distad, nearly straight in the middle, the proximal third more robust 

 than the remainder, the apex acute; subgenital plate obtuse-angulate 

 with a rather large and quite deep median V-shaped emargination, a 

 pair of moderately distinct sub-parallel longitudinal carina? present 

 on the plate. Cephalic and median limbs of moderate length ; cephalic 

 femora equal to the pronotum in length, unarmed; cephalic tibiae 

 armed dorsad with three spines on the outer margin, with six on each 

 of the ventral ones ; median femora very slightly longer than the cepha- 

 lic, unarmed; median tibia? with the dorsal margins armed with two 

 (cephalic) or four (caudal) spines, each of the ventrals with six spines. 

 Caudal femora slightly longer than the body, moderately inflated in 



Fig. 17.

the proximal half, slender distad, the greatest width contained nearly 

 six times in the length, externo-ventral margin with a single spine, 

 interno- ventral with five; caudal tibiae about equal to the femora in 

 length, all the margins spined, the dorsal ones with a number con- 

 siderably exceeding that of the ventral series. 



General colors cream white and blackish-brown, generally mingled 

 and marbled, with but little pattern aside from several rather darker 

 longitudinal areas on the abdomen and a median obsolete V-shaped 

 figure on the pronotum. The ventral portion of the lateral lobes of 

 the pronotum is pure cream-white divided sharply but irregularly from 

 the darker dorsal section. On the face, the pleura and the sides of 

 the proximal portion of the abdomen the lighter color predominates 

 or is more conspicuous on account of the marbling being coarser.
