tibia, fourteen times longer than deep, cleepest beyond the 

 middle (fig. 1 b); second metatarsal joint nearly longer than 

 the sum of the four proximal tarsal joints; terminal joint a 

 little shorter than the sum of the three proximal tarsal joints, 

 and a little more than half as long as the whole me tatarsus. 



Fourth Legs. — Very long and slender, somewhat longer 

 than the body. Femur slender, slightly more than three times 

 longer than deep (fig. 1 c). 



Flagellum. — Nearly seven times longer than deep (fig. 

 1 d), considerably curved, three- jointed; terminal joint even 

 a little more than twice as long as the sum of the two others. 

 Setse löst. 



Measurements. — Body 6.7 mm.; palps 4.7 mm.; first 

 Jegs 11.8 mm.; fourth legs 7.9 mm. 



Colour. — Thorell, who many years ago examined the 

 specimen seen by me, writes: »Cephalothorax et valpi satura- 

 tius fusci sunt, pedes paullo palJidiores; abdomen obscure ci- 

 nerascenti — vel sub-olivaceo-fuscum. Subter paullo clarius 

 quam subtus est truncus.» 



Locality. — Burma: Teinzö; one specimen, collected by 

 L. Fea, described by Thorell and preserved in the Museo Ci- 

 vico, Genova. 



Remarks. — This species is the largest form of the tribe. 

 seen by me. It agrees with T. claviger and differs from all 

 other species in three characters seen on the palps, viz. shape 

 of trochanter, armature with spines along the lower margin 

 of patella, and the extreme length of the claw. It differs 

 from T. claviger in having only normal fine acute setse on the 

 upper surface of trunk and legs.

 Male (and immature Specimeiis). 



Pl. 7., figs. 2 a— 2 k. 



Hairs. — Nearly all hairs on the upper surface of the 

 body and of femur, patella and tibia of the three posterior 

 pairs of legs thick, subclavate (fig. 2 e); most hairs on the 

 upper side of femur, patella and tibia of first legs and palps 

 subcylindrical (figs. 2 a and 2 b).
