390 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



The maxillae are rather long, strong, especially at the insertion of 

 the palpi, broadly and strongly impressed in a transverse direction, 

 curved, and incliued 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 cephalo- 

 thorax. 



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. 



Two adult males and one female were found under stones, within 

 the old-castle area at Smyrna, by myself in May 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, trun- 

 cate 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
