ANTHROOBEA TKIFOLII. 95 



on June 24th, but I think I failed with them. In 1872 

 I had larvae again, which were hibernating on Novem- 

 ber 3rd, and were first seen in motion after hibernation 

 on March 11th, 1873. In 1886 Mr. G. T. Porritt sent 

 me some nearly full-grown larvae on June 9th, which 

 began to spin on June 18th, and I bred moths July 

 7th— 14th. 



From these dates we get the period of flight in June 

 and July ; the larva stage lasting from the end of 

 June, or from some time in July, until next May or 

 June ; and the pupa stage lasting three weeks or less. 

 The only food I find I have recorded is Lotus cornicu- 

 latus. 



The egg is oblong, and rather flattened, rather over 

 1 mm. in length, and about *7 mm. in width, the upper 

 surface sunk, the shell thin and rather glistening, 

 wrinkled longitudinally, colour full yellow, rather pale 

 in tint. I have no record of the newly-hatched larvae, 

 but in E.M.M., vol. iii, p. 18, I published some obser- 

 vations on the growth and hibernation. " The larvae 

 were hatched about the end of July, and fed and grew 

 slowly till the beginning of winter. Those I had in 

 1864 were about two lines (between 4 and 5 mm.) in 

 length when their hibernation commenced, but another 

 brood which I had in 1865 were half as long again. 

 Having made up their minds that winter was coming, 

 these larvae congregated together in two or three little 

 companies on the side of their glass cylinder, and 

 spinning — each for itself — a firm foothold of silken 

 threads, put themselves side by side in position for 

 their long fast. Up to this time they had been of a 

 green tint, with rows of black spots, and this colour- 

 ing was not affected by the variation in the size, which 

 in the different years they attained before ceasing to 

 feed : but for winter wear there came in a new fashion 

 altogether; they became semi-translucent to look at, 

 and in colour dirty white ; their rows of spots changed 

 to reddish -brown, a pair of small dots only on each 

 segment being black, and their bristles seemed more
