Salticus tenebricus, sp. n. PL xi., fig. 19. 



Length of an adult male 4 mm. 



The cephalothorax is brownish black, nearly glabrous ; the thorax is 

 rounded posteriorly and about one-third longer than the caput ; the profile 

 line rises with a moderately abrupt curve from the thoracic junction, then 

 runs in a nearly even line, sloping slightly at the fore-part of the caput, 

 which is prominent ; medial fovea moderately deep. The clypeus is directed 

 inwardly, and in height hardly equals the diameter of one of the fore-lateral 

 eyes. 



The lateral eyes nearly form a square, the transverse diameter being the 

 greatest ; the intermediate laterals are equidistant between them. 



The legs are moderately long and stout, and do not differ much in their 

 relative proportions, 1, 4, 2, 3; glossy brown, suffused with black, 

 sparingly furnished with light hairs, spines moderately strong. 



The palpi are not very long, have a lighter shade than the legs, and are 

 sparingly clothed with white hairs ; the cubital joint is rather stronger than 

 the radial, the latter projects a large apophysis from its extremity, on the 

 outer side ; the digital joint is oval, convex and hairy externally, black ; 

 beneath it is reddish-brown, prominent, projecting at the base in a con- 

 vexity extending upwards to the articulation of the cubital and radial joints ; 

 at the anterior extremity there is a small black corneous process directed 

 outwards. 



The falces are broad, bowed outwardly in the centre, inclined inwardly ; 

 they are rugulose, and have a bright reddish-brown colour. 



The maxilla! are straight, broad, rounded, bright brownish-yellow. 



The labium is broader than long, pointed, brown, yellowish apex. 



The sternum oval, brownish-black. 



The abdomen is oviform, shorter than the cephalothorax, blackish-brown, 

 finely rugulose, sparingly clothed with whitish hairs.

As there is no very satisfactory natural arrangement of this large 

 family, I have thought it advisable for the present to follow the example 

 of many arachnologists, including Blackwall, and to group all the species 

 in the Latreillean genus Salticus. 



Fam. LYCOSIM. 

 Genus Sphasus, Walck. 



Sphasus gregarius, sp. n. PI. xi., fig. 20. 



Length of an adult female 5-6 mm., and of an adult male 5 mnu
