Excepting one species, all, both in the present and former papers, were sent to me by M . Eugene Simon, and were accompanied by examples of numerous other known species. A list of these latter (45 in number) with the localities in which they were found is added at the end of this paper. The whole number of species of this interesting group thus received from M. Simon amounts to seventy-nine, the greater part of them having been found in France. ERIGONE PABULATRIX, sp. n. (Plate XLIV. fig. 1.) Adult male, length nearly 2 lines. The whole of the fore part of this Spider (except the labium and sternum, which are suffused with brown) is of a clear yellow slightly tinged with orange; the cephalothorax is of ordinary form; the caput is not raised above the thoracic level, the whole profile forming a nearly uniform gentle curve; the normal grooves and indentations are slightly marked ; the clypeus is very nearly vertical, and its height exceeds (but not greatly) half that of the facial space. The eyes are in the usual position; those of the hinder row are equidistant, or very nearly so, from each other; those of the fore central pair are very minute, placed on a blackish spot, and not contiguous to each other, being divided by nearly a diameter's distance, and each of them is separated from the fore lateral eye on its side by an interval equal to a diameter of the latter, and from the hind central nearest to it by a smaller interval, more nearly equal to that which separates those of the hinder row ; those of each lateral pair are seated obliquely on a strong tubercle and are contiguous to each other. In one example of the male there was no tubercle on the right side, and the eyes of the lateral pair there were very minute, evidently in a semiaborted state ; looked at from the front, the convexity of both rows is directed backwards, that of the hinder row the most strongly. The legs are not very long, but tolerably strong, and tapering in form, their relative length being 4, 1,2, 3. They are furnished with hairs, a very few slender spines, and some short, erect, fine bristles. The palpi are short and slender (except the digital joint): the cubital and radial joints are very short; the latter is the strongest and has its fore extremity slightly produced into an obtuse point; a straight, strong, prominent, tapering, spine-like bristle, rather exceeding in length the joint itself, issues from the fore extremity of the upper-side of the cubital joint, and another longer, but less strong, and curved, springs from near the fore extremity of the radial joint, which has also a series of finer bristles round the inner margin ; the digital joint is large and of an irregular oval form, the outer margin having a strong, nearly circular, prominent lobe near the middle, and its hinder extremity being prominent in a blunt angular form: the palpal organs are directed outwards, very prominent and complex, with various corneous spines and processes; among these is a large, strongly curved, |
