BRITISH SPIDERS OF THE GENUS MICRONETA 1 29 



The epigyne is smaller than that of the two preceding 

 spiders. The central process and sexual apertures are longer 

 and narrower. This and the posterior lateral spines on tibiae 

 i. and ii. render the recognition of the female quite easy. 



M. beatus occurs amongst grass and herbage in various 

 parts of Britain. It is adult in early summer, and specimens 

 have been obtained in Dorset, Surrey, Sussex, Yorkshire, 

 Cumberland, and Northumberland.
