SCMNOBATES.

strong, conical, prominent, glossy, provided with long hairs in front, armed with teeth on the 
inner surface, and of a brownish-black hue. The colour of the maxillae and lip is dark- 
brown, with the exception of their extremities, which have a red-brown tint. The sternum 
is of an elongated oval form, with small eminences on the sides, opposite to the legs, and has 
a pale-brown hue. The legs are abundantly provided with hairs, and have sessile spines on 
the inferior surface of tibiae and metatarsi; they are of a yellowish-brown colour, with 
brownish-black annuli, the tibiae, metatarsi and tarsi of the first pair, and the metatarsi and 
tarsi of the second pair having a strong tinge of red; each tarsus is terminated by three 
claws; the two superior ones are curved and deeply pectinated, and the inferior one is 
inflected near its base. The palpi resemble the legs in colour, but are without annuli; the 
radial and digital joints have a reddish-brown tint, and the latter has a small, curved claw at 
its extremity. The abdomen is nearly cylindrical, thinly clothed with hairs, glossy, and 
projects a little over the base of the cephalo-thorax; it is of a dull yellowish-brown colour, 
with a series of contiguous, brownish-black, rhomboidal marks, extending along the medial 
line of the upper part, and numerous minute spots of the same hue on the sides and under 
part; the spinners are situated a little below the posterior extremity of the abdomen, and, 
with the branchial and tracheal opercula, have a yellowish-white tint. 
The sexes are similar in colour, but the male is the smaller, and its legs differ from those 
of the female in their relative length, the third pair being rather longer than the fourth. In 
the structure of the palpi and palpal organs it resembles the male of Segestria per Jala, and the 
colour of the latter is pale red-brown, with a spiral band of a darker hue. 
Segestria senoculata is of frequent occurrence in many parts of England, Wales, and Ireland, 
and in December, 1848, a young individual was received from Mr. J. Hardy, who captured it 
in Berwickshire. It spins a long tube, which serves for a domicile, in the crevices of rocks 
and walls, and under lichens growing on trees. Towards the end of May or the beginning of 
June the female deposits between eighty and ninety spherical eggs of a yellowish-white colour, 
not agglutinated together, in a lenticular cocoon of white silk of a fine but compact texture, 
measuring Jth of an inch in diameter, which is inclosed in a silken cell, attached to objects 
near her retreat, and covered with particles of earth and the refuse of her prey. 
This species, when in captivity, does not complete its several changes of integument and 
arrive at maturity in less than two years, and the term of its existence has been ascertained 
to extend through a period of four years. Only three spinning tubes are connected with 
each intermediate spinner of this spider; they are situated at its extremity and are of large 
dimensions. 
Genus S C II zE N O B AT E S , Blackw. 
Eyes seated on the anterior part of the cephalo-thorax ; four, situated near the frontal 
margin, describe a transverse, curved row whose convexity is directed backwards, and behind 
each lateral eye another is placed.
