First described by Petiver, about the year 1770, in 

 " Gazophylacium." In 1838 Mr. Alder separated H . 

 sericea from H. hispida; in 1829 BIr. Jeffreys H. con- 

 cinna from that species ; and in 1837 Mr. Alder sepa- 

 rated H. depilata. 



Inhabits woods, hedge bottoms, and moist places, 

 beneath stones, long grass, and fallen timber. 



During dry weather it is found in great abundance, 

 clinging to the under-side of nettle leaves, boughs of 

 trees in hedges, and to long grass. 



This species begins to lay eggs in April, and con- 

 tinues laying till September, depositing from 40 to 50 

 at a time, which hatch in fifteen days, and require from 

 fifteen to sixteen months to become fully grown (M. 

 Bouchard Chautereaux). 

 Several specimens lived under water for some days. 

 In this neighbourhood it is found [together with all 

 the varieties] at Sawley, Thrumpton, Beeston, Wol- 

 laton, Highfield House, Radford, Basford, Lenton, 

 Notiingham, Bulwell, Mansfield, Sherwood, Stanton-
