620 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



ated, in a longitudinal direction with brown ; and the underside is 

 dull pale yellow, marked with a longitudinal central dark brown 

 stripe, on each side of which, towards the margins, is a finer line of 

 the same colour ; these lines converge towards the spinners, which 

 are rather long and prominent ; those of the superior pair are pale 

 yellow, black on the uppersides, the inferior pair being of a brighter 

 yellow. 



The adult female measures about Ah lines in length, but differs 

 very greatly in colours and markings from the male, though in 

 general structure and form the sexes are much more nearly alike. 

 The female has the sides of the cephalothorax yellow, deepening to 

 a dark striated brown above, the caput black, clothed with fine pale 

 hairs, and some long white ones on the clypeus ; the two horn-like 

 tufts of black bristles below and behind the lateral eyes of the ante- 

 rior row are generally better defined thau in the male. 



The legs are yellow ; those of the first pair tinged with orange- 

 brown ; these last are much the strongest, though not so dispro- 

 portionately strong as in the male ; they are scarcely longer, if so 

 long as those of the fourth pair, the second pair being perhaps a 

 little the shortest. The palpi are short, slender, yellow, semiannu- ■ 

 lated with black. 



The abdomen is much longer in proportion than that of the male, 

 being considerably more than double the length of the cephalothorax ; 

 its general colour is pale yellow, the upperside dark blackish brown, 

 with a broadish, longitudinal, pale-yellowish, central, slightly den- 

 tated baud, spotted sparingly with small black spots, and bisected 

 longitudinally by a black line ; the sides are very sparingly marked 

 with brown ; and the underside has seldom more than a fragment or 

 two of the brown stripe and lines on that of the male. 



Adult males, together with an adult and immature females, were 

 found among rushes and herbage in a marsh near Alexandria. It is 

 a very striking-looking Spider, allied to Attus staintonii, Cambr., 

 and belongs to a group which has, as yet, no known representatives 

 in Europe. From various points in its form and structure, it seems 

 entitled to rank as generically distinct from the typical Atti; it appears 

 indeed very similar in form to some species of the exotic genus 

 Mcevia, C. Koch ; but at present, not possessing any type otMcevia, 

 I am not able to determine whether or not it is identical in form and 

 structure with the typical species of that genus.

 Yllenus saliens, sp. n. (Plate LX. fig. 92.) 



Adult male, length lg line; adult female, If to 2 lines. 



This minute but pretty little Spider is in general colours and mark- 

 ings very much like Attus 6o?metii, Sav. (described above p. 611): 

 it is, however, much smaller and generally of a brighter colour ; the 

 legs differ in length; and the palpi and palpal organs are very different 

 in their form and structure. 



The cephalothorax of the male, which is very massive, is of an
