of tortoise-shell-markeil appearance. The unequal distribution of 

 the white spots faintly indicates a longitudinal central dentated band, 

 which decreases in width as it approaches the spinners ; and the 

 black spots are chiefly arranged in a longitudinal line on each side 

 of this band. The sides are marked with a strongish curved black 

 bar towards the fore extremity, between which and the spinners are 

 two or three oblique black markings, sometimes consisting of a mere 

 spot or two, sometimes of a short continuous line. The underside 

 has a large somewhat oblong transverse patch in the middle, which 

 (lying between its ends) appears to continue the curved lateral 

 bars. 



The cephalothorax is of a somewhat orange-yellow colour, strongly 

 margined with dusky black, and with a similarly coloured longitu- 

 dinal central bar from the eyes to the indentation where the caput 

 and thorax unite. The clypeus equals two thirds of the facial space 

 in height ; it is prominent and divided longitudinally by a blackish 

 bar. 



The four central eyes form as nearly as possible a square ; and 

 those of each lateral pair are contiguous to each other, and obliquely 

 placed on a tubercle ; the intervals between the eyes of the foremost 

 row appear to be as nearly as possible equal, while the interval 

 between the fore central pair is greater than that between each and 

 the fore lateral eye next to it. 



The legs are long and slender, their relative length ], 2, 4, 3, 

 those of the first pair being considerably the longest ; they are 

 yellow (sometimes dull orange), the fore extremities of the joints 

 being more or less extensively marked with dark reddish brown ; 

 their armature consists of hairs and bristles only, the latter being 

 rather conspicuous on the tibiee and metatarsi. 



The maxillce and labium are of normal form and similar to the 

 cephalothorax in colour; the former have a largish dusky black 

 patch on the outer side ; and in some examples all the labium except 

 the apex is of a similar colour. 



The falces are not very long nor strong; they are similar to the 

 cephalothorax in colour, and marked longitudinally with blackish 

 along their inner sides in front. 



The sternum is of a glossy blackish brown colour. 



Several females, adult and immature, were found on low plants 

 near Alexandria.

A single female of this Spider was found on a prickly-pear plant 

 near Cairo in January 1864, and is identical with those found in a 

 similar situation at Beirut in the following year.
