86 PLAT Hm GCxVI 
The Caterpillar of this Infe&t is generally found under the bark 
of the willow and fallow, or on the rofe. It is probable there are 
two broods of it in the year, being fometimes taken in the winged 
flate early in the fummer, but more commonly in the month of 
O€tober ; this is the more likely, as the Englifh Aurelians firft called 
it the Herald, from an idea that its appearance warned them of 
approaching winter. 
This Infeét remains about twenty-eight days in the pupa flate, the 
Caterpillar not being found till the beginning of September.
