distinctly longer than 3, 1 is nearlj twice as broad as 2. 

 Coxa large, trochanter with numerous strong bristles, one 

 longer than the rest ; femur stout, with numerous short but 

 strong bristles and spines ; tibia about as long as femur, but 

 only about half as broad, the distal two-thirds on the inner 

 side beset with 8 pairs of short but strong spines ; tarsus 

 about two thirds length of tibia, with five pairs of spines on 

 the inner side; claw very long, thick, gently curved, no 

 knobbed digitules; in place of the claw-digitules are two 

 slender bristles ; skin colourless after boiling, delicately 

 striated, thickly beset with small round glands, between 

 which are minute hairs, not enough to make a definite pubes- 

 cence. In the abdominal region are a number of large round 

 and oval hyaline spaces, definitely circumscribed and having 

 the appearance of a nucleus and nucleolus in the middle; 

 these spaces are free from the small glands. Mouth-parts 

 well-developed. 



Cast skins of immature forms thin, white, suboval, 5 millim. 

 long, 4 broad, with antennas and legs attached. They occur 

 on the twigs.
