[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 oi 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 collection contained individuals. » SALTICUS SUBINSTRUCTUS, sp. n. 8. 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 examined) 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 tbe 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, |
