5 14 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. \_.lvXX\e 20, 



seen at first, owing to the numerous and strong hairs with which it 

 is concealed. 



FlLISTATA PXJTA, Sp. n. 



Adult female, length 2\ lines (nearly). 



This Spider is very nearly allied to F. testacea, Latr., but differs 

 from it in the whole of the fore part (including the legs and palpi) 

 being of a clear straw-yellow colour. The cephalothorax has no 

 dark margins ; nor is there any dark longitudinal band on the hinder 

 part of the caput, nor on each side of the clypeus, as in F. testacea ; 

 the legs also are quite immaculate. The colour of the abdomen is a 

 dull yellow, slightly tinged with brown. If the specimen here de- 

 scribed be of the normal adult size, it is also a much smaller species 

 than F. testacea. The eyes of the hind central pair are smaller in 

 proportion to the hind laterals than in that species ; otherwise their 

 position and relative size are very nearly similar. 



An adult and immature females were found in interstices of walls 

 at Alexandria in April 18G4.

In colours and general appearance this Spider is very similar to 

 (E. templi ; but it is larger, and the legs have on the metatarsi and 

 tarsi (of the fourth pair at least) several distinct and tolerably strong 

 prominent spines. The eyes are not so large. The interval between 

 those of the central pair (which are the largest of the eight) is equal 

 to an eye's diameter ; and the two posterior flattened angular eyes 

 are much smaller. The armature also of all the femora is of a 

 much more spinous character. The abdomen is more thickly covered 

 with white cretaceous spots ; and the cruciform marking on the upper 

 side is better defined, though of a similar character. The palpi are 

 thickly furnished with fine pale hairs; the digital joints are much 

 larger than those of CE. templi, and the palpal organs more pro- 

 minent and developed. Their structure, although on the same 

 general plan, is distinctly different in the development of their 

 processes. From CE. domesticus it may also be distinguished by its 

 larger size and the structure of the palpal organs, as well as by the 

 other marks noted above. 



An adult and three immature males, as well as two immature 

 females, were found under small sheets of web on the walls of one of 

 the temples of Upper Egypt, between Denderab and Assouan ; but 

 having lost the notes made at the time, I cannot be certain as to the 

 exact locality. 



The females had all the leg-armature, including the calamistrum, 

 rubbed off against other specimens in the bottle of spirits in which 

 they came home ; but the inframammillary organ is plainly visible 

 both in the females and males. 



Two adult males and ten females were found among the ruins of
