554 REV. O. P. CAMBRIDGE ON EGYPTIAN SPIDERS. [June 20, 



Fam. Palpimanides. 

 Gen. Palp i man us, Duf. 

 Palpimanus h^matinus ? 

 Palpimanus hccmatinus, C. Koch, Die Arachn. iii. p. 21, pi. 80. 



fig. 179. 



A female, which I take to be perhaps of this species, was found in 

 the neighbourhood of Alexandria in 1864 ; and it appears to be 

 identical with examples found in Palestine in 1865. I have since, 

 however, had occasion to doubt whether these are, or not, the true P. 

 hoematinus of C. Koch ; they are certainly different from a closely 

 allied species which I found subsequently in Corfu and at Smyrna. 

 This latter species may be the true P. hoematinus, C. K., coming, as 

 it does, nearly from the same region as the type of Koch's species. 

 The Spiders of this genus are very nearly allied to each other, and 

 are remarkably similar in their general characters and appearance ; 

 and it will require a close comparison of their respective genital 

 organs to determine the species with any certainty. 



Palpimanus savignyi. 



Platyscelum sarignyi, Aud. in Sav. Egypte, p. 167, pi. vii. figs. 

 6, 7. 



Two females, certainly distinct from that last noted, were found 

 in ascending the Nile from Cairo to Thebes. My note of the exact 

 locality has been mislaid ; but I feel little doubt that these are of the 

 same species as that mentioned in the synonym above quoted. 



Fam. Eresides. 

 Gen. Eresus, Duf. 



ERESUS PliTAGNJS. 



Eresus petagnce, Aud. in Sav. Egypte, pi. iv. fig. 1 1. 



Adult and immature females of this species were found under 

 stones near Alexandria. But for M. Simon's opinion (" Note sur 

 la famille des Eresidee," Ann. Soc. Ent. Fr. 5° ser. torn. iii. 18/3, 

 p. 357), I should have considered this species to have been identical 

 with Eresus iiuperialis, Duf. (= E. frontalis, Latr.) 



Eresus dufourii. 



Eresus dufourii, Aud. in Sav. Egypte, p. 151, pi. iv. fig. 7. 



Immature examples of this very distinct species were found on 

 low plants on the edge of the desert above Assouan. I have 

 received from Italy adults of both sexes of a species which I believe 

 to be identical with the present. It is a small species, the adult 

 male measuring only 2| lines in length, while that of the adult 

 female is no more than 3 lines.
