The Caterpillar of the Sphinx Api-formis is an internal feeder, and 
found only by making an incifion into the innermoft fubftance of the 
Poplar, the only tree the female commonly depofits her Eggs on;- it 
is to us unknown, as is alfo the time of continuing within the trunk 
of the tree; but in June, early in the morning, or in the evening, 
the Chryfalis is feen ifluing through the bark, from a perforation in the 
trunk, which the Caterpillar had formed previous to its change, gene- 
rally to the depth of fix or ‘eight inches, or more. Nature has 
furnifhed every fegment otf the Chryfalis with a double row of fharp 
teeth, or fpines, therewith it firmly attaches itfelf to the fides of the 
cavity, and, by repeated exertions to break from its prifon, gradually 
comes forth; thus, when it hath extricated itfelf from the tree, and the 
Chryfalis is fupported as in our Plate reprefented, the upper parts burft 
afunder with violence, and the infe&t rufhes forth to enjoy “ the tem~ 
perature of the fummer feafon.” It is rarely found except in Effex.
