 has not recently been found in the county. 



Sub-Section Trichia, Hartm. 



H. (Trichia) gramdata, Alder. =H. sericea, Jeff.— Very local. Kings- 

 haugh and a ditch at Scarthing Moor. In the former locality it is 

 confined to a short portion of a hedge-bottom, when first discovered 

 it was abundant, after the hedge had been cut it was much scarcer for 

 some years, now it is more common. In the other locality, distant 

 rather more than three miles in a straight line, it is found very 

 sparingly. 



H. (Trichia) rurfescens, Penn. — Dodd gives Highfield House Estate 

 on the authority of Lowe. 



H. (Trichia) hispida, ~L. >li =H. concinna, Jeff. — Widely distributed, 

 but not abundant. Nottingham Castle ; Colwick ; Wollaton ; Pleas- 

 ley ; Creswell; Worksop; Newark; Moorhouse ; Tuxford. Musson. 



Var. hispidosa, Mouss.' ;< =£/. hispida, Jeff., &c. — Abundant and 

 generally distributed. 



* As the type specimen of H. hispida in the Linnsean collection is the form concinna, 

 Jeff., this is now considered the type form. Whether this fact is sufficient to warrant 



the alteration is perhaps open to doubt.
