ULOBORUS.—GEA. 267 
margin, and clothed with grey hairs; the central pale stripe is narrow, and the thorax is gibbous above 
on each side at the beginning of the posterior slope. Near the fore extremity of the abdomen is a large 
black patch bordered with white irregular spots ; the posterior slope (in one example) is black, with two 
or three pairs of white spots placed transversely—in another example it is dusky brown, with two 
longitudinal nearly parallel diffused whitish stripes from the prominences at the top to just above the 
spinners ; the sides are either dusky or black, with two slightly oblique curved lines. The transverse 
lip in front of the infra~-mamillary organ is present. The genital aperture is also characteristically 
different from that of Uloborus signatus. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
ARGIOPE, Savigny. 
Argiope blanda, sp. n. 
Adult male, length 1? lines. 
Cephalothorax of normal form ; pale yellow in colour, clothed with short grey hairs, and with a broad longitudinal 
band of dark brown on each side, leaving a central band of yellow, narrowest at the occiput, broadening 
each way, and bifid at the anterior extremity, behind the ocular area, and a broadish marginal yellow 
band at the thorax. 
Eyes normal ; interval between the fore-centrals much greater than between each and the fore-lateral next 
to it. 
Legs moderate in length and strength, 1, 4, 2, 3, armed with distinct, but not numerous, spines. Colour dark 
brown ; the tarsi pale yellow-brown, and the posterior sides of the femora of the second pair yellow. 
Palpi short, yellow ; radial and cubital joints very short ; digital joint large, brown; palpal organs highly 
developed, prominent, complex, with characteristic spiny processes, whose exact form can only be given 
by figures. 
Falces rather weak ; deep blackish-brown in colour, with a pale yellowish patch towards their extremity on the 
inner side. 
Sternum black-brown, with a large, well-defined, yellow marking, trifid at its hinder extremity and very 
like a fleur-de-lis reversed. 
Abdomen oval, slightly truncate before, blunt-pointed behind; whitish-yellow in colour, and furnished with a 
few long bristly hairs ; a large brown subtriangular area occupies the posterior two-thirds of the upper- 
side, its lateral margins dentate, black, and with curved indentations, the anterior portion or base of the 
triangle being less dark-coloured than the rest. The sides of the abdomen are marked with longitudinal 
and oblique black lines; the underside is black (or pale, thickly marked with black) with a white 
margin, at the middle of which on each side is a strong, sharply defined, tooth-like dentation ; sometimes 
(in immature specimens of both sexes) the two dentations meet in the middle and form an angular bar. 
The female (immature) resembles the male, excepting that the legs have more yellow about them, and that on 
each side of the abdomen towards the hinder extremity is a small conical prominence, and another at 
the hinder extremity itself.

GEA, C. L. Koch. 
Gea preedicta, sp. n. 
Adult male, length rather less than 2 lines. 
Cephalothorax large ; thorax very rounded ; caput short, narrow ; lateral marginal impressions at the caput 
strong. Colour yellow-brown, closely ‘reticulated with dark brown, paler on the margins of the thorax, 
Surface clothed thinly with short grey hairs. 
Eyes occupying the whole width of the fore extremity of the caput; posterior row much the longest and greatly 
curved, the convexity of the curve directed backwards; anterior row with a very slight curve, but similarly 
‘directed; central quadrangle longer than broad, and its anterior a little shorter than its posterior side-;
