DIPOENA.—EURYOPIS. 295 
Falces moderately long, slightly tapering, almost cylindrical, straight, similar in colour to the cephalothorax, 
slightly tinged with brown. 
Palpi short, slender ; cubital joint very short ; radial joint equally short, but its fore extremity spreads, especially 
on the upperside, where it has some long, coarse, bristly hairs ; the radial joint is yellow-brown, the cubital 
and humeral joints yellow. The digital joint is brownish-yellow, very large, of an irregular form, with a 
strong prominence towards its fore extremity, and a roundish lobe at its base on the outer side. The 
palpal organs are of great size and development, consisting chiefly of a very large somewhat rounded 
corneous lobe, with some corneous processes and spines at their fore extremity on the outer side. 
Maxille strong, much inclined towards the labiwm, which is much broader than high, narrower and 
somewhat rounded at the apex. These parts are yellow-brown. 
Sternum large, subtriangular, very convex, much bent upwards at the posterior extremity, which is obtusely 
pointed. Colour yellow-brown, with an obscure paler longitudinal broken stripe along the middle. 
Abdomen globular, furnished with a few long coarse bristles, of a warm yellow-brownish colour, marked with 
many blackish-brown markings and spots: most noticeable among these is a broadish, longitudinal, 
central, rather irregular, obtusely dentated band reaching about two-thirds from the fore extremity to the 
spinners. There are two whitish spots in a transverse line just above the spinners. Underside black- 
brown, with a white spot about the middle of each side. Spinners yellow-brown. 
Legs rather short, 1,4, 2,3, brownish-yellow, obscurely marked and annulated with brown, and furnished 
with hairs and a longish prominent bristle or two on the genu and tibie. 
The female has similar markings, but it is of a paler hue; the intervals between the eyes are larger, and there 
is a good deal of white mixed with the other markings on the abdomen. Just in front of the spinners is 
a rather prominent transverse lip, no doubt covering the entrance to a spiracular organ, and about the 
middle of the upperside is a small transverse prominence at the hinder extremity of the central black- 
brown band. Sternum black-brown, this colour forming angular points opposite the insertion of the legs ; 
a lateral marginal row of largish yellow blotches, and a broad central longitudinal tapering yellow stripe, 
much suffused at the hinder extremity. Genital aperture very inconspicuous, consisting of a single 
transverse lanceolate slit. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
EURYOPIS, Menge. 
Euryopis probabilis, sp. n. 
Adult female, length 13 lines. 
Cephalothoraz broad behind, attenuated before ; caput slightly elevated, prominent ; clypeus equal in height 
to half that of the facial space ; lateral marginal constriction at the caput slight. Colour yellow-brown, 
with dusky-brown converging lines. 
Eyes in normal position, subequal; those of the posterior row in a slightly curved transverse line, the convexity 
of the curve directed forwards, and the eyes equally separated by nearly an eye’s diameter. Anterior 
row strongly curved, the convexity also directed forwards. The interval between the fore-centrals is 
greuter than between them and the fore-laterals; the latter interval being very small. The fore-centrals 
are rather the largest of the eight. The central quadrangle is longer than broad, its fore side slightly, 
if at all, longer than the hinder one. 
Legs moderately long, not very strong, 4,1, 2,3. The tibie are slightly clavate, almost as strong as—those 
of the fourth pair, indeed, stronger than—the femora. The legs are of a rather pale yellow-brown 
colour, the posterior half of the femora palest, furnished with hairs only. 
Falces similar in colour to the cephalothorax. 
Maswille and labium paler. 
Sternum dark yellow-brown. 
Abdomen rather large, oval, or nearly heart-shaped, projecting considerably over the base of the cephalo- 
thorax, and moderately convex above. It is of a dark blackish-brown colour above, marked on each side 
with a longitudinal line of pale luteous irregular spots or markings of different shapes and sizes, reaching
