BEDRIACUM.—AMAMRA. 251 
Bedriacum predator, sp. n. 
Adult male, length 44 lines. 
Cephalothorax reddish-yellow-brown, clothed with short, somewhat pubescent grey hairs. Height of clypeus 
about equal to the diameter of the fore-central eyes. 
Legs slightly paler than the cephalothorax. 
Palpi moderately long, yellow. Humeral joint robust, rather strongly curved, somewhat clavate, with several 
not very strong spines on the fore half of the upperside. Cubital joint shorter than the radial, and also 
clavate. Radial joint slightly curved, furnished with numerous bristly hairs; at the anterior extremity 
on the outer side is a small apophysis, whose extremity is notched or somewhat bifid. Digital joint long, 
its base oval, whence it is drawn out in a long finger-like form, slightly tapering to an obtuse point ; the 
drawn-out portion exceeds in length the basal part (beneath which the palpal organs are placed), and is 
divided longitudinally beneath by a long narrowing cleft, it also bends upwards from the basal part in a 
somewhat angular form. Palpal organs rather complex, well developed, with a small furciform black 
characteristic spine at their anterior extremity. 
Falces, maxille, and labium similar in colour to the cephalothorax. 
Sternum pale yellowish-brown, with a short dash of a darker hue opposite the insertion of each of the basal 
joints of the legs. 
Abdomen subcylindric-oval, of a pale dull brownish hue, clothed with hairs, among which are some long, slender, 
prominent dark ones. Spinners similar in colour to the legs. 
Hab, Mexico, Orizaba (H. H. Smith). 
“In a small silken nest, in a crevice of a cement wall.” 
This spider is nearly allied to Hutichurus and Strotarchus, Sim. 
AMAMRA, Cambridge. 
Amamra turrigera, sp. n. 
Female (not quite adult), length to spinners 23 lines; height from spinners to summit of elevation 24 lines. 
Cephalothorax of normal form ; colour brownish-yellow, broadly margined with black ; a large dusky brown 
triangular marking at the occiput, whose anterior margin is jet-black; the clypeus and fore part of the 
ocular area are suffused with dark brown, and there are also some indistinct brown marks between the 
eyes and the dark triangle. The height of the clypeus is less than half that of the facial space. 
Eyes in the normal three widely separated groups ; the central group is in front of the central prominence, the 
quadrangle formed by them broader than long, and its anterior shorter the posterior side ; the posterior 
eyes are largest. 
Legs short, 1, 2, 4, 3. Colour dull yellowish, the fore half of the femora blackish, the genual joints brown, the 
metatarsi of the first and second pairs faintly annulated with brown. Spines neither numerous nor strong. 
Falces strong, well rounded at the base in front, directed backwards ; general colour yellow, but dark yellow- 
brown at their extremity near the fang. 
Mazille and labium normal. Colour yellowish. 
Sternum yellow, with brown somewhat dentate lateral margins. 
Abdomen large, the anterior portion of the upperside produced into a high perpendicular elevation, whose upper 
extremity is wider than the middle, and divided into two somewhat subconical lobes by a deep longitudinal 
cleft; in front of and just below the cleft is a small obtuse prominence on each side, and a little below 
the base of the elevation is a longitudinal row of three smaller prominences; on the hinder part of the 
abdomen, halfway between the summit of the elevation and the spinners, is a longish, somewhat broken, 
triangular, blackish and brown marking, between which and the spinners is a longitudinal series of three 
pairs of minute deep brown points or linear spots. The rest of the abdomen is of a dull yellow-brownish 
hue, paler and yellowish-white on the sides. Underside dull blackish. The lobes at the summit of the. 
elevation, as well as the prominence in front of them, have a few black bristles intermingled with the finer 
pubescence. 
Hab. Mexico, Chilpancingo in Guerrero (7. H. Smith).
