 By the Rev. O. Pickard-Cambridge, M.A. 



Family Salticid^e. 

 Salticus citus. 



Female, immature. Length 1-fourth of an inch. Length of cepha- 

 lothorax 5-thirty-seconds. Relative length of legs, 4, 1, 3, 2. 



Cephalothorax large, square and massive, sloping abruptly at the 

 hinder part, and slightly compressed behind each posterior eye, 

 glossy and sparingly clothed with hairs. Colour black-brown, 

 paler and with a reddish tinge on the upper side, especially in 

 the ocular region, which is circled with a band of yellowish 

 hairs, commencing on either side below the outer eyes of the 

 front row. 



Eyes eight, forming three sides of a square ; the front side curved. 

 The two centre eyes of the front row more than double the size 

 of the end ones of the same row. The centre eyes of the side 

 rows are very small, and rather nearer to the hinder than to 

 the front eyes of these rows. 



Abdomen small, of a slender oviform shape, and of a deep black 

 colour. The upper side has a transverse band at the front ex- 

 tremity, formed of pure glistening white hairs ; this band is of a 

 somewhat semicircular or rather crescent shape. Towards the 

 spinners are four intensely white spots, two on each side of the 

 medial line, those nearest the spinners being the smallest and 

 nearest together. Along the centre of the hinder half of the 

 abdomen are two reddish dentated lines formed by red hairs, 

 and making a pattern of an oblong form with dentated sides. 

 Under side paler than the upper, and has four pale white longi- 

 tudinal lines converging towards the spinners. Plates of the 

 spiracles pale white. 



Palpi of moderate length. Colour black. The radial, cubital and 

 humeral joints have their upper sides fringed with intensely 

 white longish hairs. 



Legs longish and stout (the first pair much the stoutest, fourth 

 pair longest, first pair next in length, and second pair shortest), 

 clothed with hairs and black spines. Colour blackish, with a
