Rubrius cruciferus, iiov. sp. (Plate VIII, figs 3, Za-'id.) 



Female. — Cephalothorax yellow-brown, darkening anteriorly and at the sides to 

 nearly black-brown. Mandibles black-brown ; fangs black at base, red at lower 

 end. Lip and maxillae black-brown, paler in front. Sternum dark yellow-brown 

 at edges, paler in the centre. Coxae and legs yellow-brown all over, with dark- 

 brown upstanding hairs. Tarsi darker than the rest, claws dark-brown. Abdomen 

 above is dark yellow-brown, interspersed with so many black spots as to look nearly 

 black. A broad paler yellow-brown longitudinal stripe extends from the base to 

 the posterior end, where it narrows to a point ; within this, at the anterior end, is a 

 darker median stripe ; angular side-pieces come out from the sides at intervals all 

 the way down ; the pair in the middle of the back are longer than the rest, giving 

 the appearance of a St. Andrew's Cross, with the lighter colour above them. The 

 underside is dingy yellow-brown in front as far as the genital aperture, the remainder 

 being black-brown, with the exc'cption of the epigyne and spinnerets, which are 

 yellow-brown. 



The male is similarly coloured throughout, but the sternum is not so dark, and 

 the ground-colour of the abdomen much lighter through the absence of black patches. 

 The back is covered with long brown upstanding hairs. 



In some specimens the sternum, lip, and maxillae are rather pahr than in 

 others. 



The cephalic part of the crp/ialntJ/orax is long, square in front, rather abruptly 

 convex, and more so in the male than in the female. It is bounded by narrow 

 depressions, and has a slight median one extending the whole length from 

 the eye-space to the anterior end of the sulcus, with a row of short bristles 

 therein. There are also bristles on the fore part, but it is mostly smooth. The 

 thoracic part is slightly rounded at the sides, but does not add much to the 

 breadth. 



The rear row of eyes, which are equal in size, is rather strongly procurved, the 

 lower edge of the median pair being half their diameter above the ujjper edge of the 

 laterals. The median are twice their diameter apart, and three diameters from 

 their laterals, as well as the same distance from the front median, the median quadri- 

 lateral being thus longer than broad. The front row is onlv as long as the distance 

 between the rear lateral eyes, which are on a common tubercle with those of the 

 front row, the latter being slightly larger. The small median eyes are in a line with 

 the laterals, half their diameter, and equidistant from them and each other. The 

 clypeus is three times their breadth. 



The mandibles are as long as the front of the cephalothorax, slightlv kneed at 

 the base, conical, and divergent. The claws are long and strong. There are 3 

 larger and some smaller teeth on the outer edge of the falx-sheath, and 2 small on 

 the inner margin. 



The lip is longer than broad, sti'aight but slightly hollowed in front, and more 

 than half the length of the ))iaxillae, which ar(> u])right, sti-aight on the inner and 

 rounded on the outside. 



The sternum is convex, shield-shape, .straight in front, narrowing to a point 

 between the rear coxae, which are a short distance apart. All the coxae have a 

 longitudinal suture at the side.
