Female. The cephalothorax is yellow-brown, darker in the 

 lateral depressions, black-brown over the eye-space, rather thickly 

 covered with yellowish-grey hair. Mandibles, lip, and maxillse 

 bright yellow- brown with dark grey hair ; fangs dark red-brown ; 

 sternum somewhat darker, with a brown median patch and 

 upstanding brown bristles towards the rear. 



The abdomen is a greyish yellow, with a pair of black rectan- 

 gular longitudinal patches on each side of the base and a median 

 black quadrilateral, broadest in the middle and pointed at each 

 end, reaching to rather more than halfway ; on each side of this 

 again are longitudinal black patches and two more similar at 

 the rear end. The under side is dingy yellow all over, with pale 

 yellow-grey hairs and brown upstanding bristles. 



The legs are rather bright yellow, with dark grey hairs and 

 spines and brown upstanding bristles on the coxte and under side 

 of the femora, and pale grey rings on the femoral, tibial, and 

 metatarsal joints. 



The cephalothoi'cix is longer than broad, with about fovir well- 

 marked depressions on each side, and a long and deep longitudinal 

 fovea reaching from the rear slope to the cephalic part. 



The rear row of eyes is recurved ; the tops of the median pair, 

 which ai-e three-fourths of their diameter apart, reach to the 

 line joining the lower side of the laterals, which are rather more 

 than their diameter away. The front lateral eyes are 1^ times 

 the diameter of the rear median, 1^ times their diameter from 

 one another, and about 1| times that distance from the rear 

 laterals. The front median are one-fourth the diameter of, and 

 in a line with, the upper edge of the laterals. 



The mandibles are stout and strong, kneed at the base, where 

 there are long upstanding bristles ; at the apex there is a fringe 

 of downlying hair. 



The lip is about as broad as long, straight in fi-ont, and 

 broadest one-third of its height therefrom. The maxillce, slightly 

 bending over the lip, are rounded anteriorly, where they are 

 broadest and about twice the height of the lip. 



The stermom is shield-shaped, 1| times as long as broad, 

 hollowed in front and pointed at rear end between the not quite 

 contiguous last pair of coxse. 



The abdomen is oval, truncate in front, the hair covering- 

 scanty, rather short and fine.
