side ; the digital joint is oviform, blackish, convex and hairy externally ; 

 the palpal organs are not very complex, there is a prominent lobe near the 

 base, and a tooth-like projection at the anterior extremity. 



In December the females commence fabricating their cocoons ; they are 

 of a plano-convex figure, 8 mm. in diameter ; composed of a fine but very 

 compact texture ; white when newly constructed, containing about eighty 

 spherical eggs, not agglutinated together. They are attached by their plane 

 surface to bark, etc. The female usually remains upon or near the cocoon. 



These active little spiders are numerous about low herbage growing on 

 sunny banks ; they spring actively from leaf to leaf, and appear sociable in 

 their habits.
