Found on the chalk-hills between Dartford and Rochefter ; par- 

 ticularly on a long range of hillocks leading from Dartford to the 

 wood of Darent ; and hence the Butterfly has been called the Chalk-bill 

 blue. We believe it has not been found in any other part near 

 London. The larva is unknown, it appears in the winged flate, the 

 firft and fecond week in July.
