We have never found this Infe&t common, though it muft not be 
confidered as a rare fpecies; it is feldom met with near London: our 
fpecimen was found in the Caterpillar ftate at Dartford in May. It 
changed to Chryfalis in June. The fly came forth in September. 
The male is rather fmaller than the female generally, though not 
always. ‘The ftrength of their colours is very inconftant, efpecially in 
the female, which we have feen very dark in fome {pecimens; in others 
nearly as pale as the male; the general diftinction however between 
the two fexes is, the male being of a light grey with fpots and waves of 
brown, the female of an obfcure brown with fpots more diffufed.
