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 described 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 1864. Gen. GSCOBIUS, Luc. GSCOBIUS PUTUS, sp. n. (Plate LVIII. fig. 1.) Adult male, length 1| line. In colours and general appearance this Spider is very similar to CE. 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 prominent 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 Denderah 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; hut the inframammillary organ is plainly visible both in the females and males. Two adult males and ten females were found among the ruins of |
