ACHAA.—FILISTATA. 211 
anterior row is greatly curved, the convexity of the curve directed forwards. Each of the large fore-central 
eyes is contiguous to the fore-lateral on its side; the fore-centrals are a diameter or slightly more apart ; 
those of the posterior row are separated by nearly equal intervals of less than a diameter; that between 
the central pair is perhaps rather less than the others. 
Legs subequal in length, 1, 4, 2, 3, not very long, moderately strong, like the cephalothorax in colour or a 
little paler, furnished with hairs only, some of those on the femora long and of a rather bristly nature. 
Palpi short, similar to the legs in colour. Cubital joint short, strong, very rounded or nodiform in front. 
Radial joint short, broad, spreading, of a somewhat umbrella-shape, covering the base of the digital joint 
(so as to make the demarcation between the two rather difficult to see). Digital joint very large, of an 
oblong-oval form, clothed like the radial joint with coarse hairs, and also of a yellow-brown colour. Palpal 
organs well developed, not very complex, but consisting of some characteristic corneous lobes and processes. 
Falces short, rather weak. 
Mawxille moderately long, very strong, especially at the base, greatly inclined to the labium, over which they 
~ nearly meet at the extremities. 
Labiwm rather small, broader than high, the apex somewhat obtusely pointed. 
Sternum large, heart-shaped, nearly as broad as long, considerably convex, and its posterior extremity very 
obtusely pointed. These parts—falces, maxille, labium, and sternum—are similar to the legs in colour. 
Abdomen short-oval, ordinarily convex above, of a dull brownish-yellow colour, thinly clothed with rather 
coarse hairs.

FILISTATA, Latreille. 
Filistata insignis, sp. n. 
Adult male, length 14 line ; udult female, length 2 lines. 
This spider is of ordinary general form and structure. 
Cephalothorax of the female oval, broader behind than in front, where it is slightly drawn out in the centre 
into a short point. Orange-yellow in colour, margined with a black line, and with a broad somewhat 
diffused blackish longitudinal central band from the hind margin to the ocular area, whence it continues 
to the fore margin in a narrower blackish band from each lateral pair of eyes. 
Eyes closely grouped in two transverse, nearly equally curved rows, the curves not very strong, and their 
convexity directed backwards. They form a transverse oblong area nearly double as broad as long, and 
are placed on and about a strong tubercular eminence, the height of the clypeus being two-thirds 
that of the facial space. The fore-laterals are largest, and the hind-centrals smallest. The intervals 
between the eyes of the anterior row are very small but equal, these eyes being almost contiguous; each 
hind-central eye is contiguous to the hind-lateral on its side, and the two hind-laterals are separated by 
two diameters’ interval or a little less, those of each lateral pair are contiguous to each other. 
Legs moderately long, rather strong, 1, 4, 2,3. Colour like that of the cephalothorax, rather faintly and 
irregularly banded with yellow-brown. They appeared to be furnished with hairs only, though almost 
all had been rubbed off; from the same cause also, no doubt, all traces of the calamistrum had 
disappeared. 
Pali long, strong, granulose, furnished with long, coarse hairs, and similar in colour to the legs. 
Falces small, weak, straight, somewhat cylindric, furnished with coarse hairs, and similar in colour to the 
cephalothorax ; fang short. 
Mawzille and labium of normal form, but of large size; colour like that of the palpi. The maxille have at 
their termination a dark, short, sharp spine, just in contact with the fang of the falces, 
Sternum oval, yellow. 
Abdomen of a short-oval form, round behind, pale dull yellow in colour; clothed with coarse hairs, and with a 
longitudinal, central series of six triangular, deep blackish-red-brown markings, each one connected by 
its apex with the base of the one before it; on each side is a corresponding series of vertical stripes of the 
same colour, the three or four posterior ones connected with the angles at, the base of the central 
triangles next to them. Spinners normal and conspicuous, in front of them the mamillary organ, or
