Epeira SUSPICAX, sp. U. 



Epe'ira apoclisa, Sav. et Aud. Egypte, pi. iii. figs. 1, 2. 



Having carefully compared adults of both sexes of this Spider, 

 found on rushes in a marsh near Alexandria, with the European form 

 of E. apoclisa (E. cornuta, Clk.), I am convinced that it is of a 

 distinct species. It is much larger than any examples I have ever 

 seen of E. cornuta, the length of the adult male being Ah and 5 

 lines, and of the female nearly 7 lines ; there are differences also, 

 though slight, in the structure of the palpal organs of the adult 

 male. 



Inasmuch as the name apoclisa (Walck.) is now only a syuonym 

 of the older name cornuta, Clerck, it might have been well to 

 distinguish the present Spider as E. apoclisa, Sav. et Aud. ; but as, 

 until lately, this specific name has been so long the one current for 

 the European apoclisa (E. cornuta, Clk.), it will probably best avoid 

 confusion to rename it as I have here done. 



Epeira perplicata. 



Epe'ira perplicata, Cambr.Spid. Palest. & Syr., P. Z.S. 1872, p. 300. 

 Adults and immature examples of both sexes were found near 

 Alexandria. 



Epeira circe. 



Epeira circe, Sav. et Aud. Egypte, pi. ii. fig. 9. 

 Immature examples, of both sexes, of what I believe to be this 

 species were found at Alexandria. 



Epeira dromedaria. 



Epeira dromedaria, Walck. Ins. Apt. ii. p. 126. 

 Examples of this Spider were found both near Alexandria and 

 Cairo. 



Epeira atomaria, sp. n. (Plate LIX. fig. 9.) 



Adult male, length 2f to 1 J lines ; adult female, rather over 3 

 lines. 



This Spider is nearly allied to E. chloris, Sav., particularly in 

 the position of the eyes ; but it may easily be distinguished by a de- 

 cided difference of markings, as well as by its less-elongated form. 



The cephalothorax is of ordinary form ; its colour is yellow, 

 clothed with rather coarse yellowish hairs, particularly on the caput ; 

 the oblique indentations, showing the junction of the caput and first 

 thoracic segment, are broadly and distinctly marked with reddish 

 brown. 



The eyes are in the usual four pairs, rather small, and not very 

 different in size ; those of the hind central pair are near together 

 (divided by about an eye's diameter), while those of the fore central 

 pair are rather the largest of the eight and divided by a little more 

 than two diameters, this interval being equal to that between each 

 of them and the hind central eve on its side ; the interval between
