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 4\ 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 synonym 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. Epeiraperplicata, 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, pl. 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 2\ to 1 f 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 decided 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 eye on its side; the interval between |
