226 REV.O.P. CAMBRIDGE ON SPIDERS FROM ST. HELENA. [Mar. 4, 



dull yellowish coppery band along the middle of the fore half of the 

 upperside, followed towards the spinners by several angular bars or 

 chevrons of the same hue, the intervals being black : on the sides, 

 near the hinder extremity, are one or two short, oblique, black 

 markings edged with yellowish ; the whole upper surface of the 

 abdomen has a few long, black, prominent, bristly hairs distributed 

 over it ; and at the fore extremity of the upperside is a patch of white 

 squamose hairs ; the underside is dull coppery yellowish, with three 

 nearly parallel, indistinct, dark brown longitudinal stripes running 

 throughout its length. 



The female of this species, which seems nearly allied to A.petren- 

 sis (Koch), is rather larger than the male ; and the colours are not 

 so bright nor the pattern formed by them in general so distinct as 

 in the latter ; but the white marginal border of the cephalothorax is 

 a distinctive mark in both sexes, of both of which Mr. Melliss's col- 

 lection contained individuals. 



Salticus subinstructus, sp. n. 



S. illigeri, Cambr. P. Z. S. 1869, p. 543. 



Adult male, length 2 lines. 



The cephalothorax is short, broad, oval, and moderately massive ; 

 looked at in profile, the caput slopes but very slightly forwards in front, 

 while the hinder slope is rather less abrupt than in S. inexcultus ; 

 and there is a strongish transverse indentation from one side to the 

 other just behind the hinder row of eyes ; the cephalothorax is of a 

 deep black-brown colour, the ocular area quite black and thickly 

 covered with short yellowish hairs ; the central longitudinal line of 

 the hinder slope has a broadish band of white hairs ; and a few of 

 the same are dispersed in a transverse line behind the eyes of the 

 hinder row ; possibly some of these last (in the only example ex- 

 amined) may have been rubbed off ; some prominent black bristly 

 hairs are scattered over the upper part of the caput and on the 

 clypeus. 



The eyes are normal in their relative size and position, though the 

 two centrals of the front row seemed to be of a larger size than usual ; 

 they form a regular quadrangular figure, its longitudinal being half 

 the length of its transverse diameter ; the small eyes of the second 

 (or intermediate row) are nearer to the laterals of the first than to 

 those of the hinder row. 



The legs are moderately strong and not very long, not differing 

 nearly so much in the relative strength of the first and other pairs 

 as in many others of this group ; they are of a more or less pale 

 yellow-brown colour, broadly annulated with dark brown, furnished 

 with hairs and a few spines, the most conspicuous of the latter being 

 those placed in a double longitudinal series beneath the tibiae and 

 metatarsi of the first pair ; the metatarsi of the third and fourth 

 pairs have several strongish spines disposed in a sort of ring round 

 their anterior extremities ; each tarsus has a small claw-tuft at its 

 extremity. 



The palpi are short and not very strong, of a deep brown colour,
