272 REV. O. P. CAMBRIDGE ON THE [Feb. 20, 



they have two or three corneous processes in front ; the strongest of 

 these is on the outer side, and is in the form of a hook, with a 

 sharp black spiny point. 



The abdomen is black on the upperside, and yellowish mixed 

 with vinous beneath ; the branchial opercula are yellow. 



An adult of each sex was found under a stone on the skirts of the 

 Lebanon. 



Enyo lutipes, sp. nov. 



Male adult length 1| line; female adult 2|. 



This species is similar in size and general structure to E. atriceps ; 

 but the elypeus is higher, considerably exceeding half of the facial 

 space. The cephalothorax is yellow, rather tinged with orange ; the 

 upper part of the caput is of a dull red-brown colour ; the falces are 

 brown ; the whole of the underside of the Spider, with the legs and 

 palpi, are clear yellow. The leys are long and slender ; their relative 

 length 4, 1, 2, 3. The palpi are moderately long and not very 

 strong ; the radial is not half the length of the cubital joint, nor so 

 strong ; it is broadly and obtusely produced on its outer extremity, 

 the produced part terminating on its upperside in a short, strong, 

 sharply curved, and prominent sharp-pointed spine : the palpal organs 

 are well developed, but not very complex ; they have two or three 

 small, dark, corneous processes at their fore extremity, and are ob- 

 tusely prominent behind, where, from the inner side, issues a long, 

 filiform, black spine, which curves round their inner side beneath but 

 quite free from the inm r margin of the digital joint, its slender point 

 curving round beneath the fore margin of the same, and terminating 

 on the outer side of the palpal organs. 



The abdomen is short oval, very convex above (in the female it is 

 almost globular in form); it is of a glossy jet-black colour above, 

 the underside and lower part of the sides yellow; the junction of 

 the yellow and black colours is well defined and obliquely curved, 

 following the profile- line of the abdomen. 



Adults of both sexes were found under stones on the plains of the 

 Jordan, and an adult female in a similar situation at Jerusalem. 



CithjEron, nov. gen. 

 Characters of the genus. 



Cephalothorax oval, constricted laterally at the caput ; hind slope 

 gradual; profile-line even. 



Maxilla oblong, strongly curved, their outline almost semicircular, 

 inclined to the labium, and strongly, but not suddenly, impressed iu a 

 transverse direction. 



Labium large, oblong, rounded at the apex and constricted about 

 the middle. 



Sternum oval, very slightly pointed behind. 



Eyes eight, not greatly unequal in size ; in two transverse, curved 

 rows ; the curves directed backwards ; the foremost row is the most
