THERIDIOSOMA ARGENTEOLUM. 



Thebediosoma aeoenteoltjm, Cambr., Ann. and Mag. N. H., 

 1879, ser. 5, vol. 4, p. 194, pi. xii., fig. 8 



Adult female, length very slightly over 1 line. 



The colour of the cephalo-thorax is yellow, the caput suffused 

 with sooty black, especially on the sides near the occiput ; a few 

 hairs are directed forwards from the ocular Tarea, with some 

 others disposed in a central, longitudinal line running back- 

 wards. 



The eyes occupy the whole width of the caput, at its rather 

 produced extremity. Those of the hind-central pair are of a 

 blueish-grey hue, and are nearer together than each is to the 

 hind-lateral eye on its side ; the interval being half an eye's 

 diameter. Those of each lateral pair are placed slightly obliquely 

 on tubercles, the hinder one being the smallest and of a pearly 

 white hue ; the fore laterals pale greyish ; the fore centrals are 

 seated on a rather strong tubercular prominence, and are dark 

 coloured and not easily seen. The hinder row is much more 

 strongly curvod than the anterior one ; the eyes of the latter are 

 near together, but not contiguous ; the interval between the fore 

 centrals being very small, while that between each and the fore- 

 lateral on its side is little greater. 



The legs are short, moderately strong, 1.2.4.3, but the differ- 

 ence between 2 and 4 is very slight. Their colour is yellow, the 

 tibiee tinged with brownish-orange and much stronger than the 

 metatarsi. The extreme point of the metatarsi and the fore half 

 of the tarsi are black. Their armature consists of hairs, and a 

 very few prominent and rather strong bristles only. None of 

 the latter are, however, sufficiently strong to be called a spine ; 

 the tarsal claws are rather weak. 



The palpi are slender, short, of a yellowish colour, tipped with 

 blackish, and furnished with coarse bristles.
