On September 6th, 1871, Mr. George Norman, of 

 Forres, most kindly sent me some eggs laid by a 

 female of this species. The larvae began to hatch on 

 the evening of the 13th ; on the 23rd they moulted ; 

 by October 14th they were five-twelfths of an inch 

 in length, and growing fast, so that by the 20th they 

 were five-eighths of an inch long ; after this, most of 

 them ceased feeding for hibernation, but some went 

 on till full growth, moulting for the last time during 

 the latter part of November, becoming full-fed from 

 the 16th to 27th of December, and pupating shortly 

 after. The hibernating larvae did well enough whilst 

 the weather was mild, and fed a little, and got through 

 a moult in January, 1872 ; but, on the 29th of that 

 month, a severe frost killed most of them, and the 

 survivors perished in a similar way on February 21st. 



I sent some eggs to Mr. Hellins, who managed to 

 bring three larvae through hibernation, keeping them 

 in a cucumber-frame without bottom heat ; but he 

 bred only one moth (June 12th), the pupa state 

 having lasted four or five weeks. 



The food the larvas chose at first was cowslip, 

 garden riband-grass, and Ranunculus acris ; after a 

 time they seemed to prefer Potentilla rejotans and 

 Ranunculus repens, and on this last they fed up ; Mr. 

 Hellins tells me his larvas stuck to the riband-grass 

 throughout. 



The egg, as with other species of this genus, was 

 small, somewhat globular, but rather flattened above; 

 the shell glistening, with thirty blunt ribs, and faint 

 reticulations ; the colour at first dirty white, and 

 in four days there appeared a greyish-brown blotch
