LITH YPHANTES.—THERIDION. 253 
Eyes on strong tubercular prominences, subequal; fore-centrals smallest, those of the posterior row in a 
straight transverse line. The central pair rather nearer to each other than each is to the lateral eye next 
to it. The interval between those of the lateral pairs distinct, but not great. The central quadrangle 
searcely longer than broad, the fore side slightly shortest. Clypeus rather more than half the facial 
space in height, and roundly prominent at the fore margin. 
Legs short, moderately strong, 1, 4, 2, 3, furnished with hairs only. Colour dull brownish-orange, the femora 
indistinctly clouded with dark brown, the fore extremity of the tibie similarly suffused. 
Falces strong, darkish yellow-brown. 
Palpi dull brownish-yellow. 
Maxille dark yellow-brown. © 
Labium black-brown, broader than high, nearly semicircular. 
Sternum black-brown, truncated in a hollow or incurved line at its fore-margin, a little longer than broad, 
rather obtusely pointed behind. 
Abdomen short-oval, very convex above, rounded at the fore end and obtusely pointed behind, thinly clothed 
with somewhat bristly hairs, the surface slightly coriaceous. Colour jet-black, with a white line round 
the fore margin, each end extending a third or more backwards along the side; behind this are two small 
linear white spots in a transverse line, following which, near the middle of the abdomen, is a transverse 
line extending a little over the sides, and formed by three united curved lines, the middle part strongest ; 
a little way behind this are two more small transverse linear white spots; next, again, is a transverse 
slightly curved white line, followed towards the spinners by a minute white spot in the central median 
line. Just behind and a little above each spiracular opening is a short white dash or elongate spot, and 
close behind the genital aperture is a slightly curved transverse white line. The genital aperture appears 
to consist of a simple transverse slit or opening. Spinners short, compact, yellowish-brown.

THERIDION, Walckenaer. 
Theridion hispidum, sp. n. 
Adult male, length 1 line. 
General form normal. Caput and thorax looked at in profile on a level, the former sloping forwards a little in 
the ocular area, which projects at the fore-central eyes. The height of the clypeus, which is abruptly 
impressed at the upperside and perpendicular below, exceeds in height half that of the facial space. 
The cephalothorax is yellow in colour, with a longitudinal central suffused wedge-shaped blackish band, 
including the hinder row of eyes, and running to the thoracic indentation ; some strong hairs in the 
medial line and on the ocular area. 
Eyes of posterior row almost in a straight line, and nearly equal in size, and equally separated by rather less 
than an eye’s diameter. The four centrals form a square, whose anterior eyes are smaller than the 
posterior. 
Legs rather long, slender, 1, 2, 4, 3, yellow in colour; the femora of the first pair yellow-brown, furnished 
with long and some coarse hairs; a few erect bristles on the tibie, those on the fourth pair almost 
spines. 
Palpi short, similar in colour to the legs, excepting the digital joint, which is yellow-brown, large, and of a 
roundish-oval form; the radial joint is somewhat produced or spreading in front; the palpal organs are 
well developed, rather complex, directed outwards, and encircled round the margin by a long, pretty 
closely fitting, black, filiform spine which issues from near their fore-extremity. 
Falces, maxille, and labium yellow. 
Sternum subtriangular, very convex, yellow, slightly tinged with dusky, and clothed with prominent hairs. 
Abdomen short-oval, of a dull luteous colour, the anterior part of the upperside and the sides pretty thickly 
speckled with white ; a large, somewhat quadrate, tolerably well-defined white patch near the hinder part 
of the upperside, and from each of the two posterior angles of this patch a diffused black line runs 
to the spinners, the space between the black lines being more distinctly and thickly spotted with white ; 
the upperside of the abdomen is clothed, but not thickly, with long, prominent, coarse hairs. There is
