68 ARKIV FÖR ZOOLOGI. BAND 2. N:0 8. 



shows just in front of the transverse lowering mentioned two 

 sublateral low protuberances, and a little behind these and 

 nearer at the middle hne a pair of oblong longitudinal exca- 

 vations. Setse proportionateJy short, the longest pair not one 

 fourth as long as flagelkim. 



Measurements. — Body 5. o mm.; palps 3.3 mm.; first legs 

 9.0 mm.; fourth legs 5.7 mm. 



Colour. — Cephalothorax and all appendages yellow with 

 a slight tint of greenish-gray and the edgings at most arti- 

 culations bright red ; abdomen is lighter, bright straw-coloured. 



Differences accordiiig to Age. — A specimen a little more 

 than half-grown measures 3.7 mm. in length, its first legs 

 only 4.4 mm. The palps (fig. 2 h) a Httle less slender than 

 in the adult male, but showing no other difference worth 

 mentioning. First legs (fig. 2 h) scarcely ^/ä as long as the 

 body, thus much shorter and besides proportionately more 

 clumsy than in the male described; coxa terminates somewhat 

 behind the outer angle of the mandible; foot about ^/s as 

 long as tibia, only eight times longer than deep (fig. 2 i), 

 second metatarsal joint not even ha]f as long as tarsus and 

 conspicuously shorter than the sum of the four proximal joints, 

 terminal joint a little shorter than the sum of the three pro- 

 ximal tarsal joints and nearly more than ^/a as long as the 

 Avhole metatarsus. Femur of fourth legs slightly more than 

 twice as long as deep (fig. 2 k). (Flagellum löst.) Hairs as 

 in the adult. Colour, especially on cephalothorax and legs, 

 lighter than in the adult. — An immature male which is 

 somewhat larger than the juvenile specimen just described, 

 presents as to the dimensions of the joints of the appendages 

 a stage intermediate between the adult male and the young. 



Locality. — Singapore; one adult male and the two im- 

 mature specimens described (E. Simon's collection). 



Remarks. — This species is distinguished at the first glance 

 from all other forms hitherto known by the shape of the hairs 

 on the upper side of body and appendages; these hairs are, 

 besides, very conspicuous. As to shape and dimensions of 

 the joints in the appendages the species is allied to T. Grassii; 

 especially the palps show great similarity in these two species 

 and differ considerably from those in all other forms.
