received from Mr. J. Hardy, who took it in Berwickshire, and has since found adult specimens 
in the same county. The sexes pair in May, and in the succeeding month the female envelopes 
herself in an oval cell of white silk of a slight texture, on whose exterior surface are disposed 
minute pebbles, small pieces of indurated soil and other heterogeneous materials; in this cell 
she deposits between twenty and thirty spherical eggs of a pale-pink colour, which are not 
cemented together. 
Mr. It. Templeton remarks that this species is very common at Cranmore, in Ireland. 
Genus —SEGESTRIA, Lair. 
Eyes disposed on the anterior part of the cephalo-thorax ; four placed rather near together 
form a transverse row, and behind each lateral eye another is situated. 
. Maxilla long, straight, dilated at the base where the palpi are inserted, and rounded at 
the extremity on the outer side. 
Lip of an oblong quadrilateral figure, slightly hollowed at the extremity. 
Leys moderately long and robust; the first pair is the longest, then the second, the third 
pair being the shortest in females.

pair, §ths. 
The intermediate eyes of the anterior row are very near together, and those of each 
lateral pair are seated on a small tubercle. The cephalo-thorax is large, convex, and marked 
with furrows on the sides, converging towards a very slight indentation in the medial line ; it 
is of a reddish-brown colour, the region of the eyes and the lateral margins being much the 
darkest, and is clothed with hoary hairs. The falces are powerful, conical, prominent, provided 
with long hairs in front, armed with teeth on the inner surface, and of a bright, glossy-green 
colour. The maxillae are gibbous at the base; the lip is hollowed at the extremity; and the 
sternum is of an elongated oval form, with eminences on the sides, opposite to the legs. 
These parts have a red-brown hue, the bases of the maxillae and lip being the darkest. The
