XYSTICUS LUCTUOSU9. 



Tnonisus LtroTuosus, Blachw., Spid. Great Brit, and Irol., p. 78, 

 pi. iv., fig. 45. 



This spider is nearly allied to Xysticm lanio, 0. L. Koch., and 

 rosomblos it closely in sizo and form ; it has not, however, the 

 red hue, characteristic of that species, the dark parts being of a 

 dooper brown colour ; it is also less bristly, and its pattern is 

 loss distinct. 



Tho sides of tho cephalo-thorax of tho male are of a very 

 (loop, rich, blackish-brown hue, slightly marbled and stroakod 

 with yellow-brown, and with a narrow, yellowish, marginal line. 

 Tho longitudinal band is rather narrow at tho hinder part, and is 

 of a brownish-yollow colour. The central marking, behind the 

 eyes, is similar in colour to the sides, frequently marbled and 

 striped with brownish-yollow ; its fore part is somewhat 

 quadrate, and its hinder part, the sides of which are hollow or 

 incurvated, is drawn out, to the thoracic junction, into a sharp 

 linear point ; there is often a slight gap, or break near the point, 

 around which the colour is yellow. 



The legs have the femora of the first two pairs of a deep 

 brown colour, tinged with red, and slightly marbled with 

 brownish-yellow. The tibite and genua are rather paler, and 

 marked also with whitish-yellow ; tho metatarsi and tarsi are 

 pale yellowish-brown ; the spines aro not nearly so numorous 

 nor so strong as in Xysticm lanio. 



Tho palpi aro short, the colour of the humoral joint is like that 

 of tho fomora of tho logs ; tho cubital, radial, and digital joints 

 aro yollowish-brown ; tho radial is rather shorter than tho 

 digital joint, and tho apophysis at its extromity, on tho outor 

 side, is long and pointod, while that undornoath is much 

 stronger, and has a crescent-shaped termination^
