til 6 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



considerably longer than the radial and cubital joints together, of 

 an oblong-oval form, somewhat obliquely truncated at its fore 

 extremity, and clotbed with whitish hairs ; the palpal organs are 

 simple but large, and project backwards and rather outwards 

 beneatb, but free from, the radial joint, terminating in a somewhat 

 conical point. 



The falces are small, straight, nearly vertical, and of a yellow- 

 brown colour, furnished with hairs and bristles. 



The abdomeu is oval, pointed behind, hairy, and of tolerable size ; 

 the upperside is brownish black, with a strong longitudinal central 

 wbite or pale sandy grey stripe ; this stripe is well defined on its 

 edges, but is slightly broadest behind, and a very little notched or 

 irregular on the edges in that part ; the sides are slightly marked 

 with brown, as also is the underside ; but usually all markings on 

 these parts are obscured by the thick grey or light sandy-grey 

 pubescence ; the spinners are prominent, black, tipped with wbite. 



Three adult males were found in the neighbourhood of Cairo. It 

 is nearly allied to Attus fasciatus, Hahn, but (the male, at least, 

 the female being yet unknown) may be distinguished by its stronger 

 and more robust form, and the distinctness of the white stripes on 

 the cephalothorax and abdomen. It is also nearly allied to a spe- 

 cies* abundant in the neighbourhood of Jerusalem and Jericho, 

 and recorded (Spid. Palest, and Syria, P. Z. S. 18/2, p. 322) as 

 A. fasciatus, Hahn, with which species M. Simon considered it to 

 be identical. 



Having more recently found undoubted examples, in the south of 

 England, of the true A. fasciatus, Hahn, the Palestine examples 

 are proved to be quite distinct, being not only very much larger, but 

 differing decidedly in colours and in the structure of the palpi. 



Attus effigies, sp. n. 



Immature male, length 2| lines. 



Although almost denuded of hairs and pubescence, I am induced 

 to describe this Spider as new to science, since it presents a very 

 distinct pattern, and exhibits a strong likeness to a well-known 

 European form Yllenus, V.-insignitus, Clk., from which, however, I 

 think it is probably quite distinct. 



The cephalothorax is dark yellow-brown, with two longitudinal 

 yellow bands running backwards from each eye of the posterior row ; 

 these bands are partly clothed with white hairs, and probably are 

 entirely and very distinctly so in uninjured specimens ; the ocular 

 area is dark brown, clothed with a greyish pubescence, showing 

 some converging lines on its fore part, somewhat resembling those 

 lines which form the /^-shaped mark in Yllenus V.-insignitus, 



* To this Spider I now give the name of Attus interceptor. It may be dis- 

 tinguished from A. mendax (described above) by its larger size, and dark-brown 

 sides, forming, in fact, three longitudinal grey stripes on the abdomen ; the 

 radial and binder part of the digital joints of the palpi are also black-brown, 

 offering a strong contrast to the white hairs with which the cubital joint is 

 clothed ; the legs, too, of the male differ in being dark red-brown and black, 1 lie 

 tarsal joint yellow-brown, and the scopula of a sandy-greyish hue.
