Fam. EPEIRIDJE. 
Genus Epeira, Walck. 
Epeira brounii, sp. n. Pl. x., fig. 5. 
Length of an adult female 18 mm., and of an adult male 11 mm. 
The cephalothorax of the female is moderately convex, compressed before, 
rounded on the sides, medial indentation and normal grooves moderate ; it 
has a reddish-brown hue, and is clothed with silky whitish hairs. The 
height of the clypeus equals the facial space. 
The four intermediate eyes are placed on a prominence and nearly form 
a square ; the tubercles of the lateral eyes arch over the anterior pair. 
Relative length of legs 1, 4, 2, 8, first and fourth nearly equal (30 mm.) ; 
they have a red chestnut tint, and are. sparingly furnished with fine light 
hairs ; the armature consists of spines and sustentacula. 
The palpi are moderately slender and resemble the legs in colour. 
The falces are strong, vertical, and have a dark amber hue. 
The mawille are as broad as long, slightly pointed, and inclined towards 
the lip, which is somewhat oval ; these parts have a greenish-brown tint. 
The sternum is heart-shaped, has eminences opposite the legs ; is brown 
in colour, and clothed with light hairs. 
The abdomen is a broad oval, depressed above, projects over the base of 
the cephalothorax ; the ground colour is brown, and the specific markings 
have a pale ochraceous hue; the fore-pair of impressed spots form a 
transverse line with the anterior tubercles; these brown spots are inter- 
sected by the broad medial band, forming a cross-like pattern, margined 
with the paler tints ; the fore-margins have a somewhat crescent-shape, and 
the hind converge into a double loop above the posterior tubercle; between 
this conical protuberance and the two anterior tubercles there are four 
hook-shaped marks; on the lateral margins there are a series of oblique 
lines converging towards the spinners. On the ventral surface there is a 
shield-like mark with light margins, and a double row of four pits in the 
centre. The vulva consists of a long, curved, dark amber-coloured, wrinkled, 
taper, membraneous process, directed backwards; beneath it are black 
protuberances. 
The male is about two-thirds the length of the female. The cephalo- 
thoraz is oval, nearly as broad as long; medial fovea deep ; the anterior 
prominence of the caput is more pointed, and the tubercles of the lateral 
eyes more prominent than in the female; it has a brownish-amber hue. 
The legs are long, moderately stout, and resemble the cephalothorax in 
colour; there is a curved process on the coxe of the first pair; the tibiæ of 
the second pair are tumid, and have four irregular rows of spines on the 
inferior surface ; the general armature consists of numerous long spines.
