The cephalo-thorax is nearly quadrilateral, and is sparingly clothed with black and 
whitish hairs ; it slopes abruptly in the posterior region, and is prominent in front, projecting 
beyond the base of the falces, which are small, vertical, and armed with a few teeth on the inner 
surface; the sternum is oval. These parts, with the maxillae and lip, are of a brown-black 
colour, the last two, which are the palest, having a reddish tinge, particularly at their 
extremities. The legs are robust, provided with hairs and sessile spines, and are of a pale- 
yellow colour, the coxae of the posterior pair having a black spot on the upper side; the fourth 
pair is the longest, the first and third pairs are equal in length, and the second pair is the 
shortest; each tarsus is terminated by two curved claws. The palpi resemble the legs in 
colour. The abdomen is oviform, pointed at its posterior extremity, convex above, projecting 
over the base of the cephalo-thorax; it is of a brown-black colour, and has short, whitish 
hairs thinly distributed over its surface; a pale, yellowish-brown band, broader in the posterior 
than in the anterior region, extends along the middle of the upper part, and an obscure, 
narrow band of whitish hairs is curved round the anterior part, and produced on the sides 
nearly to the spinners; the sexual organs have a reddish-brown hue. 
An adult female of this species was found among herbage in a wood at Southgate, in 
June, 1850, and is in Mr. Walker’s cabinet.

The cephalo-thorax is large, glossy, nearly quadrilateral, abruptly sloped behind, 
depressed and prominent before, projecting beyond the base of the falces; it is of a fulvous 
colour, with the entire space between the eyes, a line extending along the middle of its 
posterior half, several oblique ones on the sides of that part, and the margins, of a black hue; 
the cephalic region is slightly tinged with brown, and the anterior eyes are encircled with 
white hairs. The falces are small, conical, vertical, and have a few minute teeth on their 
inner surface ; the maxillae, which are straight, are enlarged and rounded at the extremity; 
the lip is moderately long, and rounded at the apex; and the sternum has a regular oval 
form. The colour of these parts is pale, yellowish-brown, the sternum having a broad, 
black border. The legs are robust, particularly those of the anterior pair, and are 
provided with hairs and sessile spines, two parallel rows of the latter occurring on the 
inferior surface of the tibiae and metatarsi of the anterior legs; the fourth pair is the 
longest, the first pair rather surpasses the third, and the second pair is the shortest; their
