INSECTS 



Lithocolletis insignitella. Very abundant between 

 Hart Station and Castle Eden, but not recorded 

 elsewhere in England. It is so very plenti- 

 ful that I have collected 1,000 mines within 

 twenty yards. It feeds here only on 

 Trifolium pratense, though medium and 

 repens are common. The insect occurs by 

 hedges or waste ground, and is especially 

 common on the railway side
