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



teristic prominent process near the centre is short, stout, obtusely 

 pointed, and with a slightly pointed spur at its base nearly as long 

 as the process itself, with which it forms by its direction a very 

 obtuse angle. 



Falces black-brown, but in some examples (probably those 

 more recently come to maturity) yellow, merely clouded with dusky 

 brown. 



Sternum dusky brown to black, with a short yellow central stripe 

 or marking. 



Maxilla and labium yellowish dusky brown to black, with the 

 extremity of a clearer hue. 



Abdomen black, or nearly so above, with the normal markings 

 on the fore half of the upperside broad and somewhat angular in 

 the middle, fining to a point behind, and of a bright orange or lemon- 

 yellow ; this is followed to the spinners by a series of strong but 

 short angular bars, or chevrons, generally confluent, decreasing in size 

 as they go backwards, and marked with a few distinct black points 

 or spots ; the sides are yellow, more or less clouded with black ; and 

 the underside is black, margined on each side with a straight yel- 

 lowish line. Individuals are frequently found altogether of a lighter 

 hue, and with the underside of the abdomen clear yellow ; but the 

 pattern above described on the upperside may be easily traced, 

 being defined by black spots and markings on a yellow ground ; in 

 these examples the palpi are also yellow, the radial and digital joints 

 alone deepening to dusky black. 



The females generally resemble the males ; but the central cephalo- 

 thoracic band is often dilated behind the ocular area, and constricted 

 at the occiput, the anterior dilatation being more or less extensively 

 marked with yellow brown ; the normal macula and succeeding 

 chevrons on the abdomen also often form a broad dentate yellow 

 band narrowing to the spinners ; and marked with a series of pairs of 

 black points or spots ; in this sex the legs also are far more strongly 

 and distinctly annulated with brown. 



Adults of both sexes were common near Alexandria. 



Lycosa observans, sp. n. 



The adult male of this Spider is 2 lines in length. 



It is very closely allied indeed to L. inopina, and is found in the 

 eame locality and situation ; but it is rather smaller, and its colours 

 are in general far less distinct, and run more one into the other, the 

 pattern formed by their distribution being similar ; the cephalothorax 

 has no lateral yellow bands visible in either sex ; and the posterior 

 half (sometimes more) of the femora of the first pair of legs is black, 

 the corresponding part of the second pair being also suffused with 

 the same hue. The palpi are black, the radial and digital joints 

 densely clothed with hairs; the palpal organs are somewhat similar ; 

 but the characteristic process is far less strong, its basal spur being 

 of equal length with the process itself, obtuse, and forming with the 

 process a more acute angle than in L. inopina. 



It is possible that this Spider may be the L. prox'una, Koch,
