From feveral years attention to this fubje£l, I think the caterpillar 

 does not enter the wood till the fecond year of its own age ; as 

 among all the numerous larva I have found from June to No- 

 vember, I could perceive but a flight difference in fize. Probably 

 therefore they may feed on the tender bark of the fallow root the 

 firft year after they are hatched ; and it feems they eat into the 

 wood about June.^

Its caterpillar feeds on Trefoil, and changes to a pupa in June. 



The fly comes forth the latter end of Augufl. 



Thefe larva are to be met with on the uncultivated grafly chalk- 

 hills of Kent, particularly near Darent wood. They fecrete them- 

 felves under ftones in the day, and come forth to feed in the even- 

 ing. 



The male fly hab broad pedlinated antenna, a light coloured bar 

 on the upper and under wing, a flender body, with a filky tuft at 

 the anus. The antenna of the female are indeed pedinated, but 

 not to be perceived without a magnifier. It has only a faint bar 

 on the upper wings, without the leafl fign of any on the under. 

 The body is much larger, and terminates without a tuft.
