WHITE THORN. 



75 



ticularized Episema cceruleocephala, Trichiura cratagi, Cli- 

 siocampa neustria, the larva of which in some years abounds 

 in such myriads as entirely to denude the hedges of their 

 early foliage throughout large districts. Porthesia chry- 

 sorrhea and Porthesia auriflua also periodically commit great 

 devastation. The flowers also are the resort of a vast va- 

 riety of coleopterous and other insects, and afford a rich 

 harvest to the entomologist during their expansion. 



As an undergrowth in woods and plantations the Thorn 

 deserves to be encouraged, as it not only becomes an 

 excellent cover for game, but acts as a protector to other 

 trees, and with this view it is recommended by Sir Uvedale 

 Price to be planted in thickets, where, without further 

 fencing, it might act as a nurse and protector to other 

 timber trees planted amongst it.
