T h is caterpillar, which feeds on th e Hickory, w e n t in to th e ground May 28th,
and th e moth was feen th e 24th o f June. Another which w e n t into th e ground
the 12th o f September came out th e 12th o f April. T h e moft remarkable difference
between this and th e Englifh Poplar Hawk-moth, is th e flat fpreading tail o f the
chryfalis, and. th e very evidently pectinated antennas o f th e male fly. I t is n o t very-
common. T h e caterpillar is fometimes green.
Mr. Abbot very juftly remarks the affinity between this and Sphinx Populi, the antennas of
which in the male are alfo, in a degree, peCtinated; but there is not much affinity in the
marking of the wings, nor is there fo great a difference of hue between the fore and hind
wings of S. Populi as in that now before us.
