296 ARANEIDEA. 
from about one-fourth of the length from the fore part to a little above the spinners, where the two 
lines converge; these spots are flecked with white, which, perhaps, in fine-conditioned examples may 
have a silvery hue. Underside and spinners pale yellow-brown ; genital aperture of characteristic form. 
Hab. Mexico, Orizaba (H. H. Smith). 
Euryopis proxima, sp. n. 
Adult female, length 12 lines. 
Closely allied to Z. probabilis (supra, p. 295), and similar in size, general form, and structure, but differs in 
pattern and in the form of the genital aperture. 
Cephalothorax yellow-brown, with an indistinct paler converging line on each side between the caput and 
thorax, and some scratchy converging lines on the thorax. 
Eyes rather larger than those of E. probabilis, but in a similar position ; those of the posterior row separated 
by equal intervals, but of distinctly less than a diameter each. 
Legs rather short, 4, 1, 2, 8, brownish-yellow in colour, with the anterior half of the femora and tibie dark 
yellow-brown. 
Falees similar in colour to the cephalothorax. 
Mawille and labium darker yellow-brown, tipped with a paler hue. 
Sternum yellow-brown, with a longitudinal, central, pale yellow tapering line on the fore half. 
Abdomen rather large, oval, moderately convex, black-brown above, marked with pale yellowish spots and 
irregular patches, flecked with white; a large patch at the middle of the fore extremity, continued 
posteriorly by a fine broken line to about the middle of the abdomen, and other patches in a longitudinal 
line on each side to the spinners interspersed with minute spots. The middle of the underside is 
brownish, with a large irregular pale yellowish patch on each side of it extending a little way up each 
side of the abdomen. Genital aperture of a characteristically different form from that of H. probabilis. 
Spinners pale yellowish. 
Hab. Mexico, Orizaba (H. H. Smith). 
MIMETUS, Hentz. 
Mimetus rapax, sp. n. 
Adult male, length 1? lines ; adult female, 23 lines. 
Cephalothorax (of male) yellow, with a central longitudinal fulvous-brown band, gradually tapering towards 
the hinder part, the edges somewhat dentate, and with some small yellowish patches within its limits. 
Clypeus about half the height of the facial space. 
Eyes unequal in size, the fore-centrals much largest and placed on a strong prominence; the central 
quadrangle much broader in front than behind, the sides and fore side about equal in length; those of 
each lateral pair contiguous to each other, on a strongish tubercle. 
Legs long, rather slender, 1, 2, 4, 3, furnished with numerous spines of different length and strength, and 
arranged in the normal symmetrical order. They are yellow in colour, marked and annulated with 
reddish and yellowish-brown. 
Falces long, straight, not very strong ; colour orange-yellow, the fore part deep reddish-brown. 
Palpi short, yellow ; cubital joint very short, nodose, with two long, strong, tapering bristles in front ; radial 
joint longer than the cubital, of atumid or oval shape, furnished with .several long similar bristles of 
different lengths; digital joint large, of irregular form, and with some strong bristles in front. Palpal 
organs highly developed and prominent, composed of various corneous processes, and with a long circularly 
bent black spine surrounding them. 
Mawxille long, Theridiiform, somewhat pointed at the extremity, inclined towards the labium ; colour yellow- 
brown, paler at the upper ends. 
Labium large, roundly convex in front, broader than high, somewhat rounded at the apex; colour like that 
of the maxille.
