322 Falconer : The Spiders of Wicken, Cambridge. 



Falces short, slender, strongly suffused with black both on 

 anterior and inferior surfaces, with obscure yellow brown 

 oblong longitudinal streaks. 



Maxillae, except on the inner margin and the labium except 

 on the anterior edge which are whitish, entirely suffused 

 black. 



Sternum of a dusky hue, with a broad darker marginal border ; 

 its entire surface covered with numerous small round 

 yellow brown spots. 



PALPUS, figs. 9, 10, II, black. 



Tibia, short and stout, enlarged at distal extremity, 

 widely and shallowly excavated a-t anterior margin : no 

 proper apophysis, but the external angle strongly and 

 shortly produced, its apex slightly curved outwards, and 

 ending in a point. 



Tarsus oval, slightly hollowed on each side to receive the 

 angular extremities of the tibia, with a distinct black 

 border, longer than the tibia and patella ; a lighter col- 

 oured patch near the extremity showing a number of 

 small round dusky yellow brown spots, and covered with 

 white hairs beyond which is a cluster of stronger black 

 hairs. 



Palpal Organs, figs. 9 and 10, dusky brown, the greater part 

 exserted from the tarse, and projecting backwards to the 

 base of the tibia. Bulb, oval, its posterior extremity 

 attenuated and rounded ; near its summit a strong, very 

 oblique transverse fold ; close to the base of the tarse on 

 the inner side springs a long black spine which extends 

 in three wide curves to the very apex of the joint (figs. 

 9 and II (a) ; through its lowest curve, exserted con- 

 siderably beyond the tarsal margin and very conspicuous 

 when viewed from above, a prominent stout yellow-brown 

 process slightly elevated at the upper external angle, and 

 ■ densely covered especially at apical margin with very short 

 strong denticulae. (Figs 9, 10, lib). 



LEGS, order of length, 4, i, 3, 2, Legs I a little thicker than 

 the others. Femur I, slightly compressed and enlarged, 

 with numerous long black curved bristles on its upper 

 surface. Tibial and metatarsal spines, long and slender ; 

 tibiae, 3-3 beneath ; metatarsi, 2-2 beneath. Contrary to 

 Simon's characterisation of the genus in his Ai-achnides 

 de France, Tome 3, p. 208, where the posterior legs are 

 stated to be without spines, the metatarsi of III and IV 

 are provided with spines but they are much shorter than 

 those on I and II ; met. Ill, with four apical spines, the 

 two beneath stronger than the two above, met. IV, two 

 beneath only, but more laterally placed. A^. reticulatiis 

 Bl. has these spines also.
