HANSEN AND SÖRENSEN, THE TARTARIDES. 45 



The claw is rather long, about ^/ö as long as the upper tarsal 

 margin. 



First Legs. — Rather slender (fig. 2a) and a httle more 

 than ^lo as long as the body. Coxa terminates rather shortly 

 behind the outer angle of the mandible. Femur scarcely longer 

 than tibia. Foot a little more than •'/4 as long as tibia, very 

 slender (fig. 2c), viz. scarcely thirteen times longer than deep, 

 deepest at the end of metatarsus; second metatarsal joint as 

 long as the sum of the five proximal tarsal joints and half 

 as long as the whole metatarsus. 



Fourth Legs. — Slightly longer than the body; femur 

 two and a half times longer than deep (fig. 2d). 



Flagellum. — Long and very slender (fig. 2 e), seven and 

 a half times longer than deep ; second joint much shorter than 

 the third, the sum of the three proximal joints scarcely -/s of 

 the whole length. The longest setse a little more than half 

 as long as the flagellum. 



Measurements. — Body 4. .5 mm.; palps 2.7 mm.; first legs 

 6.2 mm.; fourth ]egs 4.7 mm. 



Colour. — Anterior part of cephal o thorax, the antennae, 

 palps and, at least partly, the first legs bright reddish yellow; 

 the remainder of the body and the other legs light yellowish, 

 straw-coloured. 



Differences accordiiig to Age. — In an immature male 

 the body measures 3.8 mm. and first pair of legs 4.3 mm. 

 Palps nearly as in the adult female; the lower front angle of 

 trochanter (fig. 2f) about 110°. First leg in most respects 

 as in the adult female; foot (fig. 2g) proportionately a little 

 longer than in the adult, scarcely ten times longer than deep; 

 second metatarsal joint conspicuously shorter than the sum 

 of the five proximal tarsal joints, terminal joint distinctly 

 longer than the sum of the three proximal tarsal joints and 

 somewhat more than half as long as metatarsus. Flagellum 

 (fig. 2h) is thickened in its basal half, showing the animal 

 to be an immature male. Cephalo thorax with the three an- 

 terior pairs of appendages less reddish and more yellowish 

 than in adult females; the remainder as in that sex. 



Locality. — Venezuela: Corosul, near Caracas; three adult 

 females and the immature male described (E. Simon's col-
