Tetragnatha FILIFORMIS. 



Eugnatha Jiliformis, Sav. et Aud. Egypte, p. 120, pi. ii. fig. 4. 



An immature male and two adult females of this species were 

 found in the same situation as the last, near Alexandria. The great 

 prolongation of the posterior extremity of the abdomen (increasing 

 its length by two thirds) makes the determination of this Spider easy. 



Tetragnatha pelusia. 



Tetragnatha pelusia, Sav. et Aud. Egypte, p. 1 19, pi. ii. fig. 3. 

 An immature female, of what I believe to be this species, was found 

 near Cairo.

This Spider is similar in size, form, aud structure to 5 1 . albovittafu, 

 Westr. {JEpeira calva, Bl.) ; but an apparently constant difference in 

 the abdominal pattern, and in some other points, convinces me that 

 it is of a distinct though very nearly allied species. The upper- 

 side of the abdomen in S. albovittata, has three broad longitudinal 

 denticulate bands, the central one of a cream-white colour, and that 

 on each side reddish yellow-brown ; these latter unite at their poste- 

 rior extremities, and thus form a transverse band at that part ; these 

 three bands are immaculate ; the central one distinctly terminates 

 well inside of the transverse portion of the lateral bands, represented 

 on this portion, at most, by a small yellowish spot. In S. ajfinis, 

 however, these bands are not so vividly traced, and the lateral ones 

 are of a dull blackish-brown hue, broken in upon and mottled with 

 pale yellowish white, and they are connected at their posterior ex- 

 tremities by a very narrow bar, or simple line, the central band thus 

 running to the same length as the lateral ones ; moreover the cen- 

 tral band is divided longitudinally from end to end by a distinct 

 tapering stripe of reddish brown (or other colour similar to that of 

 the lateral bands) giving off lateral lines at intervals, which appear 

 again to divide the central band in a transverse direction. The legs 

 and palpi differ also from those of S. albovittata by being yellow, 

 distinctly crenellated with brown ; the falces also have a brown 

 patch at each end, the legs and palpi of that species, as well as the 

 falces, being of an immaculate orange-yellow. Another difference 

 is observable in the four central eyes ; these in the present Spider 

 form an exact square, while in S. albovittata the form is of a qua- 

 drangle rather longer than broad. 



Two females were found on low plants near Alexandria. 



Singa lucina.

Adult females of this Spider were found among rushes and plants 

 in a marsh near Alexandria.
