1872.] NEW SPECIES OF ERIGONE. 749 



has a longitudinal central row of bristly hairs directed forwards, the 

 two hinder ones being the longest and widest apart. The caput and 

 thorax are confluent, and the normal grooves and furrows are not 

 strongly defined ; the height of the clypeus exceeds half that of the 

 facial space, and it is rather strongly impressed just below the eyes, 

 and prominent near the lower margin. 



The eyes are seated on tubercles, those on which the lateral pairs 

 are placed being strong ; they are not very unequal in size ; those 

 of the hinder row are about equidistant from each other ; each eye 

 of the hind central pair is separated from that one of the fore 

 central pair opposite to it by a space not much greater than the 

 diameter of the former. The legs are of moderate length, 4, 1, 2, 3 ; 

 their colour is yellow, the femora and tibiae being bright orange ; and 

 they are furnished with hairs, some of which, on the uppersides, 

 are erect. 



The palpi are not very long ; they are of a greenish-yellow colour 

 suffused with brown, especially on the radial and digital joints ; the 

 cubital joint is short, strong, and somewhat gibbous in front ; the 

 radial joint is small at its junction with the cubital, but enlarges 

 quickly, and is produced at its outer extremity into a strong, ob- 

 tusely ending, and slightly bent apophysis ; it is also rather promi- 

 nent (or produced), both at its hinder and inner extremities ; the 

 digital joint is large, somewhat truncate at its extremity, beneath 

 which the palpal organs have a strong coiled and rather prominent 

 black spine connected with them ; and in contact with it there is 

 some semitrausparent, whitish membrane. The sternum is heart- 

 shaped, convex, furnished with a few bristly hairs, and similar in 

 colour to the cephalothorax. The maxillae and labium are normal 

 in form, and of a rather lighter colour than the sternum. 



The abdomen is rather large, of an oval form, and moderately 

 convex above ; it is glossy, and of a jet-black colour, slightly rugulose, 

 and sparingly furnished with short, strongish hairs ; some minute 

 ones have a golden lustre in some lights when in spirit of 

 wine. The falces are strong, straight, and nearly vertical ; they 

 exceed in length the height of the facial span, and have a cluster of 

 fine sharp teeth towards their inner extremities. 



The female is rather larger than the male, and has the abdomen 

 much more convex above ; but in colour and other general characters 

 the two sexes are similar. 



An adult example of each sex, found near Nuremberg, was 

 received for examination from Dr. L. Koch. It is very nearly allied 

 to Neriene saxatilis (Bl.), but may be easily distinguished by the 

 form of the radial joints of the palpi, and by the coiled spine con- 

 nected with the palpal organs ; from Erigone sundevallii (Westr.) 

 it may be at once distinguished by the absence of spines beneath 

 the legs of the first two pairs.
