RHOMPHAA.—EGILONA. 187 
and the height of the clypeus, which is prominent, is equal to two-thirds of that of the facial space; an 
ill-defined black stripe runs along each side of the thorax, and another from each of the fore-lateral eyes a 
little obliquely outwards to the lower margin of the clypeus; a long, strong projection issues prominently 
forwards from the middle of the ocular area, its form being that of a goose’s neck and head, furnished 
with strong hairs, and terminating in a slightly curved tapering spine. 
The eyes occupy the upper part of the prominence of the caput. The four centrals form a large square. The 
slight curve of the posterior row is directed backwards, and the strong curve of the anterior row forwards ; 
the interval between the hind-centrals is equal to one-half or nearly two diameters, but from each to the 
hind-lateral on its side is scarcely more than one-fourth of a diameter, those of each of the lateral pairs 
are contiguous to each other, and the fore-lateral on each side is very nearly contiguous to the fore- 
central eye on its side. The fore-centrals are largest of the eight. 
Legs very long and slender, 1, 4, 2, 3, and greatly unequal in length, furnished with fine hairs only; their 
colour is pale yellowish, marked and spotted with yellow-brown, mostly in the region of the different 
articulations, 
Palpi rather long, slender, similar to the legs in colour, but the humeral joint has a black well-defined stripe 
along its anterior side. The cubital and radial joints are both somewhat clavate, the latter is considerably 
the longest, and is also curved upwards at its fore extremity, where it is furnished with strong bristly 
hairs. The digital joint is not very large, equal in length to the cubital, oval, pointed at its foreend. The 
palpal organs are not very prominent; of the several corneous processes one on the outer side ends in a 
_ slender, curved, not very long, tapering spine. 
Falces neither long nor strong, similar in colour to the cephalothorax, with an indistinct black stripe down the 
front of each. 
Mazille long, strong, greatly inclined towards and in front of the labium. Colour pale yellow. 
Labium large, semicircular, being a continuation, without sign of junction, of the sternum ; it is also circularly 
convex in front. 
Sternum very convex, elongate, subtriangular, its posterior extremity broadly and considerably produced 
between and beyond the coxe of the fourth pair of legs. The colour of the sternum and labium is 
similar to that of the falces, their sides, however, are irregularly but closely marked with black ; from the 
beginning of the coxe of the fourth pair of legs to the extremity of the produced sternum it is com- 
pletely black. 
Abdomen produced at its hinder extremity into a nearly erect, tapering, pointed eminence, equal in height to 
the length of the cephalothorax and abdomen (to the spinners); it is of a dull luteous hue, with one or 
two blackish markings, but almost completely covered with more or less coalescing silvery spots; its 
point ends with a distinct slightly tapering thorn-like (but apparently not corneous) projection, 
The female resembles the male in general colours and markings, but these are in this sex better and more 
distinctly marked ; on the fore part of the abdomen is a narrow, blackish, tapering, longitudinal dentated 
marking, and the projecting part of the abdomen is much longer in proportion. The clypeus also projects 
more forwards.

Mr. Smith remarks that the web in which these spiders were found was not, he 
thinks, that of their own making. ‘This corroborates what we already know of the 
habits of this group, which are quasi-parasitic. 
EGILONA *, gen. nov. (Theridiide), 
Cephalothorax short-oval, obtuse in front, rather longer than broad; lateral marginal impression at caput not 
very strong, but gradual and distinct. Caput rather elevated, and prominent at the ocular region ; the 
profile rises gradually and evenly, a very slight hollow behind the occiput, which is very slightly convex ; 
height of the clypeus equalling more than two-thirds of the facial space, it is prominent at the lower 
margin, but impressed below the eyes.
