BRITISH SPIDERS OF THE GENUS MICRONETA 131 



M. saxatilis Bl. is abundant in most localities during the 

 summer, where it is found near the ground amongst herbage 

 of all sorts. It is recorded for a dozen English counties, and 

 occurs also in Scotland, Ireland, and Wales. 



Microneta simplicitarsis Sim. (Arach. de France, vol. v., 

 435 and 436) is a true Micryphantes, and agrees with M. 

 beatits, mollis, and saxatilis in possessing spines on the 

 posterior borders of the first two pairs of tibiae between the 

 middle and apex of each. 



The lamella characteristica and epigyne are quite char- 

 acteristic. The species, of which Dr. de Lessert has kindly 

 sent me examples, has not yet occurred in Britain. 



Genus III. MICRONETA Menge, 1868. 



Metatarsi i. and ii. without spines. 



Long sensory set?e present near the apices of all four 

 metatarsi. 



Tibia i. with an extra spine near the apex on the anterior 

 border. 



Posterior eyes subequal, the centrals a shade nearer to the 

 laterals than to each other. 



The falces show great sexual dimorphism. Those of the 

 male are very attenuated towards the apex, highly divergent 

 and much hollowed out on the inner side. 



The anterior border of the fang groove shows no teeth, but 

 near it are placed one large and several small dentiform hair- 

 bearing tubercles. The posterior border shows five or six 

 strong teeth, the second from the proximal end being the 

 largest. 



The falces of the female are obliquely truncated. The 

 anterior border of the fang groove shows five large, well 

 separated teeth ; the posterior border also possesses five, but 

 these are very small and very closely placed.
