BRITISH SPIDERS OF THE GENUS MICRONETA 1 33 



obliquely truncated in the females. The anterior border of 

 the fang groove bears two teeth, and the posterior one, in both 

 sexes. 



Posterior eyes of medium size, subequal and nearly equi- 

 distant. 



The clypeus in this genus is frequently very high, but this 

 is a most variable character. 



The tibia and tarsus of the female palpus are tumid, and 

 together form a more or less club-shaped termination to the 

 limb. The width of this varies in the different species.

The examination of the types of the above species com- 

 pletely establishes their identity. 



The male of this spider is easily recognized by the lamella 

 characteristica of the palpus. In addition to this, the ex- 

 tremely high and conical dorsal prominence of the palpal 

 tarsus is distinctive, although the height is rather variable. 

 The female is easily recognized by the palpus, the epigyne 

 and the cephalothorax. 



In the first place the palpus is only very slightly tumid. 

 The last two joints are thickened, and have a transverse 

 diameter of about '09 mm., 1 that of the palpal femur being 

 about "06 mm. The termination of the limb is thus only 



1 Measured across the dorsal surface of the widest part.
