The falces are of the usual characteristic form, and similar in 

 colour to the cephalothorax. 



The maxilla, labium, and sternum are rather paler in colour than 

 the cephalothorax, but present nothing at variance with the generic 

 type ; the sternum is finely clothed with coarse hoary hairs. 



The abdomen is oval and projects considerably over the base of 

 the cephalothorax ; it is of a yellowish brown colour, clothed with 

 hoary, yellowish, and blackish hairs intermixed ; it has a narrow ill- 

 defined dark brown longitudinal central bar on the fore half of the 

 upperside, cruciform at its hinder part, and followed by a series of 

 angular lines or chevrons to the spinners ; these lines terminate 

 laterally in indistinct spots or blotches ; and outside the two or three 

 hindermost blotches are some ill-defined spots or patches of hoary 

 hairs, of which there are some more in two tufts just above the 

 spinners ; the underside is of a dull brownish yellow hue, clothed 

 with greyish hairs and with pale lateral margins. 



An adult female, evidently of the same species, is considerably 

 larger, and the abdomen covered with cretaceous white spots ; the 

 longitudinal central brown marking on the fore half of the upperside 

 is broader, better-defined, and angular on its lateral margins, and 

 the spots laterally terminating the succeeding angular bars are well 

 defined, forming two longitudinal rows converging to the spinners : 

 the underside has a broadish longitudinal brown band ; and the 

 spinners are surrounded by several short blackish radiating elongate 

 spots or short bars. The usual supernumerary mamillary organ 

 is present, together with calamistra on the metatarsi of the fourth 

 pair of legs ; the latter, however, do not exist in the males. 



Two adult males and two females, one adult, the other immature, 

 were beaten from the branches of the Sont Acacia in lower Egypt 

 in Februarjr 1864.

Adults and immature examples of this Spider were found among 

 the dead stems and debris of bushes and under stones near Alexan- 

 dria in April 1864. In the same month of the year following I met 

 with it more abundantly under stones and fragments of rock and 

 among debris on the plains of the Jordan. 



The synonymic reference above to M. Eugene Simon's 'Arach- 

 nides de France ' is, I feel sure, correct ; but there seems much reason 

 to doubt the correctness of the reference quoted by that author from 

 M. H.Lucas's 'Exploration en Algerie;' the Epeira albomaculata, 

 Luc, seems to me by no means certainly of the same species, or even 

 genus, as that described and figured /. c. by M. Simon.
