CRAMBUS WARRINGTONELLUS. 



Plate CLX, fig. 14. 



Of this species I received last year, 1880, two 

 batches of eggs, the first on the 14th of August from 

 Mr. W. H. B. Fletcher, and obtained by him in the 

 New Forest, and supplemented afterwards with a few 

 more, and the second batch six days later from Mr. J. 

 Gardner, of Hartlepool, and to both friends I return 

 many thanks. 



AH the eggs were laid loose ; those from the South 

 hatched on the 16th of the month, and up to the 1st 

 of September ; those from the North began to hatch 

 on the 27th of August, and had finished on the 29th. 



The young larvae from these wide apart localities 

 were kept separate, and placed in pots with growing 

 plants of Festuca duriuscida, Aira flexnosa, and some 

 other grasses of a hard nature ; their progress was 

 noted up to the middle of November, when they 

 began to close their numerous galleries for hiberna- 

 tion, after having very considerably ravaged the 

 grass. 



In the early spring of 1881, I noticed a great 

 number of them busily engaged in afternoons, when- 

 ever the sun shone on the pots, spinning threads in 

 all directions round the outside of the grasses, which 

 had in the interval recovered in a great degree ; but 

 for some time after this I was unable to attend to 

 them, until at length I observed the grass to be 

 nearly all dead; then, when almost too late, I had 

 the mortification to find that the greater part of them 

 had deserted their quarters, though enough still re- 

 mained to serve my purpose of figuring the larvaa and 

 breeding the perfect insects. 



The moths from the New Forest were bred from 

 the 7th to the 17th of July, and those from Hartlepool 

 from the 13th to the 17th of July; and here it may
