294 ARANELDEA. 
ACHZEA, Cambridge. 
Achzea mendax, sp. n. 
Adult male, length scarcely 1 line. 
This spider agrees with the typical Achwa insignis, Cambr., P. Z. 8. 1882, p. 428, t. 30. fig. 5, in all 
excepting the relative size of the eyes of the fore-central pair, which in that species are greatly larger 
than the rest, while in the present spider they are scarcely, if anything, larger than the hind-centrals. 
The cephalothoraa is of normal Theridion form; caput prominent, especially on the side of the fore-central 
eyes; clypeus much impressed, and about equal in height to half that of the facial space. Colour 
yellow-brown, marked with converging streaks and markings of deep brown. Thoracic indentation large 
and deep. 
Eyes rather large, subequal ; posterior row slightly curved, the convexity of the curve directed backwards, 
these eyes equally separated by about two-thirds of the diameter of the centrals. The central quadrangle 
is distinctly longer than broad, its anterior eyes very prominent and directed forwards, separated 
from the fore-laterals by a very narrow interval, but not quite contiguous to them, and from each 
other by an interval about equal to that which separates those of the posterior row. The fore side of 
the quadrangle is, if anything, slightly wider than the hinder side. 
Legs rather long, 1, 2, 4,3; those of the first and second pairs much the longest, and furnished with 
longish hairs and bristles, some of a spiny character; most of these on the femora of the first and 
second pairs had been broken off, leaving only the tuberculous-looking stumps. Colour orange-yellow- 
brown. 
Palpi short, similar in colour to the legs; the radial joint is shorter than the cubital, but broadly and 
obtusely prolonged at its outer extremity, which is furnished with a marginal row of long, strong, 
tapering bristles; digital joint oval, with a strong rather bent obtusely-pointed projection at its 
extremity. The palpal organs consist of a large corneous lobe, which is broadest behind and has its 
fore extremity broken up into some short characteristic spines and projections. 
Falces similar in colour to the cephalothorax. 
Ma«xille and labium yellowish, tinged with brown. 
Sternum large, heart-shaped, angularly prominent between the basal joints of the legs; its posterior 
extremity broadish, obtuse, and strongly bent upwards between the coxe of the fourth pair of legs. 
Colour yellow. 
Abdomen somewhat cylindric-oval, obtuse at its hinder extremity; colour dull luteous-brown, with no 
apparent pattern, but irregularly spotted with black and furnished thinly with long, coarse, pale 
yellowish bristly hairs; halfway between the spiracular plates and the spinners is a long transverse 
semicircular prominent fold, but whether connected with a fissure or not could not be determined owing 
to the rather shrunken general condition of the epidermis. 
Hab. GuateMaLa, Coban (Sarq). 
DIPOENA, Thorell. 
Dipoena proba, sp. n. 
Adult male, length scarcely ? of a line (1:5 millim.); adult female, slightly over 1 line (2 millim.). 
Cephalothorax, looked at from above and behind, very nearly circular; fore part of caput above prominent. 
Clypeus much impressed, and its height about half that of the facial space. Colour brownish-yellow 
tinged with orange; a broad dark brown central longitudinal band includes the ocular area and narrows 
a little at its abrupt termination near the thoracic indentation ; there is also a broad, lateral, not very 
sharply defined, brown band on each side which includes the clypeus. 
Eyes of tolerable and nearly equal size, all pearly-white, excepting the fore-central pair, which are darkish 
grey. Those of the hinder row equidistant from each other, the intervals being rather less than a 
diameter ; this row is slightly curved, the convexity of the curve directed backwards. The central 
quadrangle is a square whose fore side is longer than the rest ; each fore-central eye is almost contiguous 
to the fore-lateral eye on its side.
