STORENA.—RUBRIUS. 
STORENA, Walckenaer. 
Storena lauta, sp. n. 
Adult female, length 3 lines. 
This species is of normal form and structure. 
The cephalothorax is of a dark rich reddish-brown colour, smooth; much longer than broad, of an oblong-oval 
form, roundly truncate in front, very convex above; normal indentations (excepting the thoracic one) 
obsolete, and the profile-line forming a strong and regular curve; the lateral marginal impressions at the 
caput are moderate. Clypeus rather prominent and rounded, exceeding considerably in height half that 
of the facial space. 
Eyes rather small, subequal ; in two transverse, equally curved rows, the convexity of the curve directed 
backwards, the anterior row much the shortest ; central quadrangle longer than broad, and the fore side 
shorter than the hinder one ; the hind-central pair are much nearer to each other than to the hind-laterals, 
being separated by less than a diameter; each lateral pair with the hind-central eye next to it forms 
nearly an equilateral triangle, or at any rate an isosceles triangle whose base is the line formed by the 
lateral pair. The fore-central eyes are smallest, and nearer together than to the fore-lateral eyes. 
Legs not very long nor strong, +, 1, 2, 3, armed with spines, chiefly on the third and fourth pairs; on the 
genuc of these pairs are two spines on the outer side and another at the posterior extremity near the 
outer side ; terminal tarsal claws three, destitute of scopula and claw-tuft. Colour reddish-orange-yellow. 
Palpi similar to the legs in colour. 
Falces moderately long, powerful, rounded in front, somewhat directed backwards, red-brown, and furnished 
in front with short coarse bristles. 
Mawille short, strong, somewhat pointed at their inner extremities and much inclined to the labium. Colour 
yellow-brown. 
Labium slightly broader than high and rounded at the apex. Colour dark reddish-yellow-brown. 
Sternum short-oval, broadly truncate in front, produced into a short rather fiae point behind, between the eoxe 
of the fourth pair of legs, which are almost contiguous to each other. 
Abdomen oval, fore margin rounded, rather broadest a little past the middle. It is black in colour on the 
upperside, thinly clothed with coarse prominent hairs, and with a large inverted V- or U-shaped white 
bar at the fore end occupying a third of the length of the abdomen ; following this backwards are three 
pale angular bars or cheyrons, with a more or less strong, oblique, pale bar at the hinder end of each, 
reaching to the spinners, and following the last chevron is a conspicuous, white, somewhat elongate, trian- 
gular patch ; the sides and underside are pale dull luteous; near the spinners the sides have two or three 
oblique black streaks; the underside is marked with four irregular, longitudinal, black markings, and 
another transverse angular one a little way in front of the spinners; these are compact, orange-yellow, 
the inferior pair longer and stronger than the superior. The genital aperture is inconspicuous, but of 
characteristic form.

RUBRIUS, Simon. 
Rubrius mordax, sp. n. 
Adult female, length 43 lines. 
Cephalothorax longer than broad, truncated in front; lateral marginal indentations at the caput tolerably strong 
and abrupt. Colour reddish-yellow-brown, paler on the lateral margins; two broad, longitudinal, well- 
defined, yellow-brown bands, one on each side, having a marginal pale reddish-yellow border of more than 
half its width, and a central one of a deeper hue, broader before than behind, and longitudinally bisected 
by a deep brown line which ends just behind the hind-central pair of eyes. The profile curves over to the 
ocular area from the hinder slope, which is rather short and tolerably steep, at about an angle of 45°. 
The cephalothorax is clothed with short fine hairs. Height of the clypeus less than half that of the 
facial space. 
Eyes in two transverse rows, rather closely grouped ; posterior row very nearly straight, the convexity of its
