 male (fig. 3 d) and 110^ in the female (fig. 3 g). Femur 

 (fig. 3 g) has its lower margin rather flatl^^ rounded, the angle 

 is very obtuse and very conspicuously longer from the basal 

 than from the distal end of the upper margin of the joint. 

 Patella in the male slightly more than, in the female scarcely, 

 three times longer than deep. Tibia three and a half times 

 longer than deep. Claw slightly less than half as long as the 

 upper margin of tarsus. 



First Leg-s. — Male (fig. 3 c): Very slender and exceed- 

 ingly elongate, even slightly more than twice as long as the 

 body. Coxa terminates somewhat in front of the outer angle 

 of the mandible (fig. 3 b). Femur even a little shorter than 

 tibia. Foot rather little more than half as long as tibia, 

 extremely slender (fig. 3e), being even more than sixteen 

 times longer than deep, deepest at the end of metatarsus; 

 second metatarsal joint unusually long, only a little shorter 

 than the whole tarsus; second tarsal joint unusually long, 

 conspicuously longer than the third; terminal joint as long as 

 the sum of the two proximal tarsal joints and between ^/s and 

 ^4 as long as the whole metatarsus. — Female (fig. 3f): 

 Legs slender, nearly '^j-.i as long as the body. Coxa terminates 

 slightly behind the outer angle of the mandible. Femur 

 exactly as long as tibia. Foot ^/o as long as tibia, very slender 

 (fig. 3h), thirteen and a half times longer than deep ; second 

 metatarsal joint proportionately a little shorter than in the 

 male, slightly longer than the sum of the five proximal tarsal 

 joints; second tarsal joint as in the male; terminal tarsal joint 

 as long as the sum of the two proximal tarsal joints, and one 

 third as long as metatarsus. 



Fourth liBgs. — Male (fig. 1 a) : Very slender and so- 

 mewhat longer than the body; femur a little less than four 

 times as long as deep. — Female (fig. Ib): Slender and
