Lake Tekapo, Canterbury, A.T.J] . 



Fam. SALTICIDJE. 

 Genus Salticus, Latr. 



Salticus zanthofrontalis, sp. n. PI. xi., fig. 12. 



Length of an adult male 5 mm. 



The cephalothoraz is somewhat quadrilateral, of a dull black hue, finely 

 rugulose ; irregularly clothed with yellowish hairs, lateral margins convex, 

 edged with fine hairs ; the profile line ascends abruptly from the thoracic 

 junction, then runs with a slight slope to the occiput which projects a little 

 over the falces. The height of the clypeus equals the diameter of a fore- 

 lateral eye. 



The ocular area is large, the hind-lateral eyes, which are the furthest 

 apart, are placed near the verge of the posterior slope, and form with the 

 faint fovea a transverse line ; the small intermediate laterals are nearest 

 to the anterior laterals ; a rim of yellow lanceolate hairs curves over each 

 of the fore-central eyes, and under the fore-laterals ; the lower margins of 

 the fore-centrals have white hairs of a similar form, and a few are scattered 

 over the clypeus. 



Eelative length of legs, 1, 4, 2, 3, the first pair is longest and most 

 robust; the femoral joints have a dark mahogany hue, the genual and 

 tibial joints, especially of the first" pair, have a crimson tinge; the metatarsi 

 and tarsi are brownish ; black and white hairs ; armature normal, spines 

 strong ; the tarsi terminate with a pair of weak claws and scopula. 



The palpi are furnished with hairs only, and are similar in colour to the 

 legs ; the humeral joint is rather long, the cubital and radial joints short, 

 the latter is black, somewhat globose, and projects an apophysis near its 

 articulation with the digital joint, which is long and narrow, convex, hairy 

 and black above ; beneath it is moderately convex, reddish-brown, with a 

 large pad-like protuberance. 



The falces are vertical, broad, flat, finely rugulose, black ; furnished with 

 long white hairs, and strong teeth. 



The maxilla, are strong, broad, somewhat obliquely truncated, inclined 

 towards the lip, which is nearly triangular ; these parts are dark brown with 

 light apices. 



Sternum oval, black, few white hairs. 



The abdomen is oviform, and resembles the cephalothorax in colour and 

 clothing ; ventral surface black, yellowish hairs.
