The _abdomen_ is elongate oval, and of a straw yellow colour. In the _male_ the fore part of the upper side is irregularly black brown, followed by an irregular somewhat broken longitudinal central bar, and some broken oblique lines and portions of chevrons. In the _female_ the fore part is less densely blackish, the central longitudinal line is obscure, but the oblique lateral lines are more distinct and less broken, but none are quite united so as to form chevrons, though the two or three nearest to the spinners almost do so. The upper side is furnished with numerous strong nearly erect black bristles. The _labium_ has a row, of bristles only, at its apex. The markings of the cephalothorax in the female are very nearly like those of that sex in _N. Manderstjernæ_; the tapering orange yellow band, however, behind the eyes appears to be rather bolder, as in that species this band also is faintly traceable quite to the hinder thoracic margin. The inner corner of the base of the maxillæ, in both sexes, has several minute tooth-like black spines. The form of the cephalothorax in the female differs from that of the male; in the latter sex (male) it is narrower before and rather rounded behind; in the former sex (female) it is broadest before and more distinctly hollow-truncate behind; the caput is also rounder and more elevated. In the female the tarsi and metatarsi of the two first pairs of legs have close set brush-like hairs beneath; these are wanting in the two hinder pairs, and also almost entirely wanting on the two first pairs in the male. Various other characters, both peculiar and differential, are noted in regard to this species by M. Simon (l.c.). It is to be regretted that this painstaking observer did not note more exactly the form and type of its nest; from his description of it, however, it appears to be branched, but whether the door is of the wafer or cork type, or whether it has an inner door or not, is not mentioned. _Habitat._ Corsica. Nemesia Congener, sp. n., Plate XVIII., fig. A, p. 225. Adult female, length 9 lines (19 mm.). In general appearance, colours, and markings this spider bears great resemblance to _N. cæmentaria_. The eyes, however, appeared to be smaller, and the hind-centrals also smaller in proportion to the rest. The pale margins of the cephalothorax are in the present species generally confined to some rather indistinct pale patches. The central orange band from the eyes to the thoracic fovea is, especially in immature examples, often only a simple tapering line; in others it is larger, and often composed of three converging narrow orange bands, which form, in some examples, a broad central tapering band, marked with two longitudinal dark lines. The thoracic fovea is curved, but not sharply.
