156 ARANEIDEA. 
FAVILA *, gen. nov. (Aviculariide, Simon ; subfam. Ctenizine ; 
eroup Cyrtaucheniee). 
Cephalothorax perceptibly longer than broad, rather narrower at its posterior than at its anterior extremity. 
Thoracic indentation large, deep, strongly curved, the convexity of the curve directed backwards. Caput 
but slightly higher than the thorax, rising in a very gradual slope to the eyes, when looked at in profile. 
Eyes in two transverse, slightly curved rows, forming a transverse quadrangular area, its transverse diameter 
just double the length of its longitudinal. The curves of the two rows are opposed to each other, that of 
the anterior row directed backwards, that of the posterior row directed forwards. The fore-lateral eyes 
are the largest, the hind-centrals the smallest. 
Legs moderately long, strong, 4, 1, 2, 3 or 4, 1, 3, 2, not greatly unequal in length, armed with more or less 
strong spines, excepting the tarsi of the first, second, and third pairs, those beneath the tibie of the first 
and second pairs strongest, one towards the fore extremity of the tibie of the first pair much longer and 
stronger than the rest, and also one of a similar nature nearer the hinder extremity of the tibiee of the 
second pair. These tibize are incrassated, those of the first pair most strongly. Scopula beneath all the 
tarsi, excepting those of the fourth pair. Superior terminal tarsal claws toothed in apparently two 
rows, but not uniformly on all the tarsi. 
Palpi moderately long, strong; radial joint much longer than the cubital, incrassate and rounded, larger in 
the middle than at the extremities, furnished with numerous spine-like bristles and fine spines. 
Falces tolerably powerful, armed with numerous closely-grouped dentiform spines and spine-like bristles at 
their upper extremity on the inner side. . 
Mazille longer than broad, the sides parallel, a small number of minute blunt teeth at their base on the 
inner side. 
Labium very small, broader than long; apex roundish, pointed, looking like a piece let into the sternum, 
which is excavated or hollowed out to receive it. 
Sternum longer than broad, much the broadest behind, where it is of a somewhat obtusely subangular form ; it 
has on it six shallow smooth impressions—four form a transverse, slightly curved line near the middle, the 
two central ones of these are much the largest and pear-shaped, the other two oval; opposite to and in 
front of each of the latter is another small, roundish, rather indistinct one. 
Abdomen short, oblong-oval ; spinners of superior pair moderately long, tapering ; terminal joint shorter and 
less strong than the middle one. 
Favila relatus, sp. n. 
Adult male, length 6 lines ; length of cephalothorax 3 lines, breadth of ditto, 23 lines. 
The whole of the fore part of the spider is yellow-brown, the cephalothorax marked with rather irregular 
converging blackish-brown lines or streaks, and the sides of the caput somewhat suffused with brown ; 
the surface of the cephalothorax has a few hairs and bristles on it; the legs have a longitudinally striate 
appearance, from the hairs being arranged in stripes, with bare intervals of a rather paler hue than the 
rest. The eyes of the anterior row are about equally separated, and the row itself is very slightly longer 
than the posterior row ; the fore-laterals are a little larger than the fore-centrals ; the hind-laterals are of an 
elongate form, at right angles with the fore-laterals, and separated from them by less than an eye’s 
diameter ; the hind-centrals are considerably the smallest, of an oblong-oval form, and separated from 
the hind-laterals by the smaller diameter; the curve of the two rows is about equal and slight, that of 
the anterior row is directed backwards, that of the posterior forwards. The clypeus has several strong 
black curved bristles, prominent at the middle; its height is about twice the diameter of the fore-central 
eyes, or rather less than half the height of the facial space. The third pair of legs have the genua armed 
on the outer side with numerous short tooth-like spines. 
The palpi have the digital joint very short, and there are numerous short bristly hairs at its upper fore extremity. 
The radial joint is long, tumid, or incrassated, and furnished with numerous bristly hairs on its fore part 
underneath. The palpal organs are well-developed, of a somewhat duplex-lobe form, the larger or upper 
lobe having a twisted appearance, and issuing from it is a curved tapering pointed spine.
