but does not extend round the posterior part, which, with the underside, is of a dark blackish-red-brown, 
the sides being a little paler, but traversed obliquely by deeper coloured ruge. 
The spinners are short and of a dark reddish-brown colour.

This spider is nearly allied to S. maculosa; but the anterior legs of the male are 
proportionately shorter and stouter, the abdomen has no dark spots on its upperside, 
the palpi differ in their structure, and the eyes have a slightly different relative 
position. 
From Mr. Sarg’s note on the male it seems that the colour of the tarsi and metatarsi 
of the first two pairs of legs is pale green, and the whole of the third and fourth pairs 
olive-green, the abdomen also is pale olive-green, showing how little in some cases the 
colours of the preserved specimens can be relied upon as representing the spider in life. 
In his note upon the preceding species, S. maculosa, Mr. Sarg does not specially 
mention its colours, but remarks its near general resemblance to S. affinitata, excepting 
the dark spots on the abdomen; whence we may conclude that some portions also of 
S. maculosa are in life greenish as in the present species.

Adult male, length 13 lines. 
The cephalothorax is of a dull brownish-yellow colour, with a broad thoracic marginal border well defined, 
broadest in the middle, and of a deep reddish-brown hue. The surface is furnished with a few long, 
tolerably strong, tapering black bristles. 
The eyes are in the usual position,—two very nearly concentric, strongly curved transverse rows, the convexity 
of the curves directed forwards. The fore laterals are rather larger than usual. They are seated on 
rather pale tubercles, and have each a narrow, clear yellow margin. Those of the anterior row are very 
nearly equidistant from each other, if anything the interval between those of the central pair is greater 
than that between each of them and the lateral next to it; the interval between the hind central pair is 
considerably less than that between each of them and its contiguous lateral eye. The four central eyes 
form an oblong rectangular trapezoid. 
The legs, 2,1, 4,3; those of the first and second pairs are long, rather slender, those of the second pair being a 
little the longest. The femora are granulose, and with the genua and tibie are dark yellow-brown, the tibiz 
having an obscure annulus of a paler hue near its base; the metatarsi and tarsi are yellowish. They are 
armed (excepting the tarsi) with many longish black spines, these being most numerous on the tibie. The 
two hinder pairs are short and yellow. 
The falces are moderate in length and strength, vertical, and similar in colour to the cephalothorax. 
The palpi are short, similar to the posterior legs in colour. The cubital joint is slightly longer, but less strong, 
than the radial; it has a long, strong, tapering, slightly curved, prominent black spine above at its anterior 
extremity. The radial joint has, along with some others of lesser size, a black tapering spine on its inner 
side nearly equal in size to that on the cubital joint; also at its outer extremity is a rather small, slightly 
curved, sharp-pointed, somewhat spine-like, apophysis. The digital joint is of moderate size and yellow- 
brown hue, clothed with hairs and bristles. The palpal organs are simple, and encireled by a black spine. 
The mawille, labium, and sternum are of normal form, the two former of a pale yellowish-brown colour, the 
latter yellow. . 
The abdomen is oval, with the upperside rather flattened convex, shining, and somewhat shield-like; its colour 
is pale luteous-yellow, with three transverse rows of dark red-brown spots, four in each row, and each 
bearing a long, strong, tapering black bristle ; between the hinder row of spots and the spinners are. two 
black patches in a transverse line, and another just above the spinners. The sides of the abdomen
