ACHAA.—THERIDION. 131 
Falees straight, neither very long nor strong, and, with the mawille and labiwm (which are of normal form), 
pale yellow. 
Sternum subtriangular, brownish-black. 
Abdomen rather elongate, very convex above, the hinder part gradually raised to a subconical termination, 
with a vertical slope, rather forwards, to the spinners. The upper part, sides, and hinder slope are white, 
with a broad, longitudinal, central brown band on the upperside to the conical point, the sides being 
marked more or less distinctly with a strong inverted vandyke pattern of a yellow-brownish colour, having 
a straight, vertical, white stripe down the middle of the hinder slope to the spinners; these last are 
short, compact, and surrounded by a circlet (deficient in front) of largish round white spots. The under- 
side is of a dusky drab colour, with a black patch immediately in front of the spinners, and a large 
transverse oblong-oval figure, open behind, formed by a black marginal line, between the spinners and 
the genital aperture, which is very small, but simple, and of characteristic form.

Since the description of the female was printed (anted, p. 108), I have found the male among Mr. Champion’s 
Bugaba (Chiriqui) collection. This sex resembles the female in size, colours, and markings, but the latter 
are more vivid and distinct. The palpi are short, pale yellow; the digital joint is large, dark yellow- 
brown; the palpal organs are prominent and compact, but complex, with characteristic spines and 
processes.

THERIDION, Walckenaer. 
Theridion purum, sp. n. 
Adult female, length to extremity of abdomen 13 lines, to spinners | line; height of abdomen from spinners 
iy: 
1j lines. 
The cephalothoraz is of normal form and pale yellowish-brown in colour, the ordinary indentations and a

central line from the eyes to the occiput of a darker brown. The clypeus retreats immediately below the 
eyes, and its lower margin is prominent ; its height is a little greater than half the facial space. 
eyes are of tolerable size, subequal, and closely grouped together. They are in two transverse, abont 
equally curved, lines, the convexity of the curves directed away from each other. The four centrals form 
a square, the anterior pair seated on a strongish tubercular prominence of the ocular area. The interval 
between the hind-centrals is scarcely an eye’s diameter, and very slightly greater than that between each 
and the hind-lateral eye next to it. The fore-central pair are dark coloured, the rest pearly-white. 
legs are short, moderately strong, 1, 2, 4, 3, of a pale yellowish colour, slightly tinged with brown at 
the anterior extremities of the joints, most strongly on those of the tibie and metatarsi of the fourth 
pair. They are furnished with coarse hairs, and a slender spine on the genual and one or two spines 
on the tibial joints. 
The palpi are short, yellow-brown, the digital joint more than double the length of the radial. 
The falces, mawille, and labiwm are normal in form, and of a yellow-brown colour. 
The sternum is rather elongate, subtriangular, strongly convex, and yellow-brown in colour. 
The 
abdomen is large, much elevated on the upperside, its height being more than double its length, and 
ending in a small somewhat subconical prominence. It is of a pale dull yellow-brown hue, closely 
mottled with whitish. The conical prominence is black in front and pale behind, and a little way in 
front of it, on each side, is a narrow but very distinct rather oblique zigzag black line, bordered behind 
with awhite line. A faint brown line runs upwards, on each side of the spinners, on the hinder perpen- 
dicular slope. The genital aperture is small, inconspicuous, but of characteristic form.
