198 ARANEIDEA, 
Sternum somewhat subtriangular, heart-shaped, much longer than broad, its posterior extremity gradually 
drawn out, but its end truncated. Colour (with the labium) deep black-brown. 
Abdomen large, looked at in profile triangular, the posterior part being produced gradually into a conical point 
at the beginning of the hinder slope, which is almost vertical, and equal in length to the length of the 
abdomen on the underside. It is dull yellowish-brown in colour, marked with white stripes, spots, and 
markings; the larger spots and markings are along each side of the median line of the upperside, leaving 
a longitudinal band sprinkled with minute white spots. This band, ill-defined, contains near the middle 
four black spots in a quadrangle, longer than broad, and narrowest behind; at the hinder extremity of 
the band is a dark brown patch reaching to the highest point of the abdomen; the sides and hinder slope 
are striped nearly vertically with long and short white stripes. The underside is jet-black, interrupted a 
little in front of the spinners and forming there a black triangle with a pale spot in the middle of its base ; 
four bright white spots in a square surround the spinners, and on each side near the spiracular openings 
is a large white spot or patch. The spinners are short, strong, and compact. The genital aperture is 
rather obscured, but is of characteristic form. 
Hab. Guatemaua, Cahabon (Sarq). 
Mr. Sarg has the following note on this spider — Caught in its circular web on 
bushes.” As this spider is undoubtedly of the family Theridiide, and very near to 
Theridion, this note—if taken to show that the spider spun the web in which it was 
found, and that it was a geometric one—is of great importance, since no true Theridiid 
is yet known to spin a geometric snare. 
TEUDIS, gen. nov. (fam. Drasside ; subfam. Anyphenine). 
Cephalothorax longer than broad, but not greatly so, very broad and almost squarely truncate in front; lateral. 
marginal impressions at the caput slight; normal indentations slight, upper convexity moderate, hinder 
slope rather abrupt, profile almost level, very slightly curved; clypeus equal in height to the diameter of 
the fore-lateral eyes. 
Eyes subequal, fore-centrals smallest, the rest almost equal, in two transverse slightly curved rows, the ante- 
rior row shortest, the curves about equal, the convexity of the anterior row directed forwards, that of the 
posterior row backwards ; those of the hinder row equally separated, of the anterior row nearly so; the 
central quadrangle as broad as long, but much narrowest in front. 
Legs moderate in length and strength, 1, (those of the second pair are broken off), 4, 3 (probably the second 
are slightly longer than the fourth, or at all events not shorter), armed with strongish spines, but 
not regularly disposed; hairs coarse, long, prominent, especially on the metatarsi and tibie of the first: 
and (probably) the second pairs. Tarsal claws 2, 4-5-denticulate, with a not very dense claw-tuft. 
Scopula absent. 
Falces long, strong, slightly tapering, straight, porrected, excavated along the basal two-thirds of the inner 
margin; fang long, strong, articulated not quite horizontally, but a little obliquely, and when at rest 
lying along almost underneath the falx, as in Delozeugma, Cambr. Teeth beneath the falces minute, but 
with a strong denticular prominence about the middle, with numerous strong bristly hairs between it 
and the articulation of the fang. 
Mawille long, strong, straight, slightly divergent, narrow at the articulation of the palpus, broad and rounded 
at the extremity, blunt-angled on the outer, obliquely truncated on the inner side. 
Labium much longer than broad, and more than half the length of the maxille; sides nearly parallel, a little 
converging at the apex, which is deeply emarginate. 
Sternum oval, truncate before, slightly and obtusely produced behind, between the posterior cox, which are 
separated by a space equal to their diameter. On the middle of the underside of the abdomen is a very 
distinct transverse oval opening to, no doubt, a spiracular organ. 
This genus has affinities with Delozeugna, Cambr., and Chiracanthum, C. L. Koch, 
also with Anyphena, Sund.
