Show 390 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, The maxilla are rather long, strong, especially at the insertion of the palpi, broadly and strongly impressed in a transverse direction, curved, and inclined towards the labium, which is rather long, being two thirds the length of the maxillae, of an oblong form, and rounded at the apex. These parts are rather darker in hue than the cephalothorax. Sternum similar in colour to the cephalothorax, glossy, and of an oval form, rather pointed behind. The abdomen is about equal in length to the cephalothorax ; it is rather broad, somewhat truncate before, but broadest, and rounded, behind; its convexity above is not great, and it scarcely projects at all over the base of the cephalothorax ; it is of a dull mouse-coloured black hue above, thinly clothed with hairs; six short pale line-like spots in three pairs form two curved longitudinal lines of three spots each near the middle of the upperside, the curves being directed inwards and towards each other ; analogous spots are observable in many other Drassi, especially in D. troglodytes; the underside of the abdomen is of a paler hue than the upperside. The spinners are six in number, brownish yellow and of moderate size, those of the inferior pair being the longest and strongest. The female resembles the male in colours. The form of the genital aperture is very characteristic, but not easily described ; reference to the figure (Plate LI. fig. 14 c) will give a good idea of its distinctive form. T w o adult males and one female were found under stones, within the old-castle area at Smyrna, by myself in M a y 1865. DRASSUS HEBES, sp. n. (Plate LI. fig. 15.) Adult male, length 3 lines. The cephalothorax of this species is of an oblong-oval form, truncate at each extremity; the hinder slope is short and rather abrupt, and the caput slopes forward slightly from just behind the eyes, the intermediate profile-line being level; its colour is yellow-brown, deepening in the ocular region; and it is thinly clothed with fine hairs ; there is only the slightest possible lateral constriction on each side at the caput; but the normal grooves and indentations are fairly marked and indicated by darker yellow-brown converging lines. The eyes are not very large, they are placed in two slightly curved and almost parallel transverse rows on the fore part of the caput, but not occupying more than half its width ; as looked at from above and behind, the curve of these rows is directed backwards. The eyes of the hind central pair are oval, oblique, very near together, but not contiguous ; each lateral eye of the hinder row is separated from the central of the same row nearest to it by a space about equal to the longest diameter of the latter ; the front row is shorter than the hinder one, and the four eyes composing it are, apparently, equally separated from each other; if any thing the interval between the fore centrals is a little greater than that between each and the fore lateral nearest to it; those of each lateral pair are divided by an interval about equal to the diameter of the hind lateral; the fore centrals are |
