120 ARANEIDEA. 
maxille, labium, and sternum are also similar in colour, the extreme tips of the maxille and labium 
whitish-yellow. 
The abdomen is of a short broad-oval form, slightly pointed behind, and of the usual somewhat flattened form. 
Its colour is black; on each side of the upper surface towards the hinder extremity is a large irregular 
bright rather pinkish-red patch, leaving the black in that part to represent, in a suffused or irregular 
manner, the usual transverse angular bars or chevrons. The upperside is also spotted with small white 
points, the chief of them being the five normal impressed punctures, in a longitudinal series of two trans- 
verse rows of two each, two corresponding, one behind, and a single central one in front. The sides are 
longitudinally rugulose, the rug marked with minute yellowish-brown dots. The upperside has a few 
strong black tapering bristles on its surface. The underside has on its jet-black surface a longitudinal 
series of ten or twelve minute white points in two rows, converging from the genital aperture to the 
spinners. The colour of the spinners is dark yellow-brown. The genital aperture is of a characteristic 
form, with a deep black-brown border just in front of it.

No number accompanied this spider to indicate its exact locality. 
Synema interrupta, sp. n. 
Adulé male, length 1% lines. 
Cephalothorax of normal form, smooth, glossy, showing none of the normal indentations; colour deep rich 
brown, slightly paler at the fore extremity ; a few strong prominent spine-like bristles on the caput and 
hinder slope ; height of the clypeus nearly but not quite equal to half that of the facial space. 
Eyes in form of a regular crescent, occupying the whole width of the upperside of the fore extremity of the 
caput. The four centrals form a quadrangle broader than long, its hinder side being very slightly the 
longest, and the eyes forming it the smallest of the eight. The eyes of the fore-central pair are distinctly 
wider apart than each is from the fore-lateral eye on its side; the fore-laterals are slightly the largest of 
the eight ; the interval between the hind-central pair is slightly greater than that between each and the 
hind-lateral eye next to it. All are on tubercles, those of the four centrals very slight. 
Legs strong, 2, 1, 4, 3, those of the second pair very slightly, if anything, longer than those of the first pair, 
armed, excepting the tarsi, with strong spines, those beneath the tibie arranged in three pairs, beneath 
the metatarsi in two pairs. The tarsi end with two curved pectinated claws, beneath which is a tuft of 
bristly hairs opposed to them. The colour of the femora and tibiz of the first two pairs is similar to that 
of the cephalothorax, the hinder half of the tibiee as well as the metatarsi and tarsi yellow; the whole of 
the third and fourth pairs being also yellow. 
The palpi are brownish-yellow, short; the cubital and radial joints of equal length, armed with a few strong, 
spine-like, tapering bristles. The cubital joint has a small, prominent, slightly curved, and rather obtusely 
pointed apophysis at its anterior extremity on the outer side. The digital joint is rather small; it is 
equal in length to the radial and cubital joints together. The palpal organs are simple, and closely 
margined with a long, black, filiform, tapering spine. 
The falces are strong, conical, vertical; the basal half in front deep brown, like the cephalothorax; the rest 
yellow-brown. 
The maxilla, labium, and sternum are of normal form, of a brownish-yellow colour, the sternum dark brown 
along the middle. 
The abdomen is of a short-oval form, flattish above ; its upperside is furnished with a few long, prominent 
tapering, spine-like bristles. Its colour is yellowish-white, and a large patch of the same colour as the 
cephalothorax, with two angular points on each side, occupies a considerable portion of the hinder half 
of the abdomen, and reaches to the spinners; connected with this patch is a lateral longitudinal stripe 
on each side of the same colour, and which also encircles the spinners. The whole of the central area of 
the underside is of a similar deep rich brown colour and margined with white. A marginal band to the 
dark patch on the upperside is whiter than the rest. 
A not quite adult female differs from the male in having the legs shorter, all of them yellow, excepting a 
small deep red-brown patch underneath the hinder extremity of the tibie of the first and second pairs.
