Show 1876.] UEV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. 611 S. vaillantii, Luc. Explor. de 1'Alger. Arachn. p. 136, pl. v. fig. 2. The identity of the two Spiders mentioned iu the above synonyms appears to be undoubted. Adult and immature examples of both sexes were found near Cairo and Alexandria, generally on old walls. I have received lately adults of both sexes from the Mauritius, from Edward Newton, Esq., and also from Bombay, from Major Julian Hobson (H.M. Staff Corps). ATTUS SOLDANII. Salticus soldanii, Sav. et Aud. Egypte, p. 1S1, pl. vii. fig. 17, 18. An adult male and several female and immature adults were found near Alexandria. ATTUS MONARDI. Salticus monardi, Luc. Explor. de 1'Alger, p. 156, pl. vii. fig. 1. A n adult male of this distinct and pretty species was found near Cairo. ATTUS FULGENS. Salticus fulgens, Cambr. Spid. Pal. & Syr., P. Z. S. 1872, p. 340, pl. xiv. fig. 17. Adults of both sexes were not unfrequent on trees and plants, near Alexandria, Cairo, and in Upper Egypt. This is one of the most brilliant and pretty of all the Salticides I found in Egypt; and its golden green iridescent abdomen distinctly spotted with white renders it an easily determined species. ATTUS REGILLUS. (Plate LX. fig. ] 7.) Attus regillus, L. Koch, Verhand. zool.-bot. Ges. Wien, p. 879. Adult and immature males with immature females were found near Cairo and in Upper Egypt on trees and low shrubs, and subsequently in similar situations near Smyrna and Ephesus. I have also received it from Bombay. I include this Spider in the genus Attus on M . Simon's authority; but I conceive that the peculiar, almost circular form of the cephalothorax entitles it to generic separation from the typical Atti. A similar form of cephalothorax is not unfrequent in several other (as yet undescribed) exotic species. ATTUS BONNETII. Attus bonnetii, Sav. et Aud. Egypte, pl. vii. fig. 14 ( $ ). Attus canescens, Cambr. Spid. Palest. & Syr., P. Z. S. 1872, p. 323. Adults of both sexes of this species were found near Alexandria, and also at the roots and among the stems of stunted plants on the desert near Jebel y Silsilis, in Upper Egypt. Savigny and Audouin describe and figure only the female ; the male (length 2} lines) differs in the abdomen wanting the double longitudinal nearly parallel series of short oblique pale streaks on the upperside ; instead of these there is a broad longitudinal central |
