LECTURE IX. 
Trojan division one of the most magnificent is 
the Papilio Priamus or great black and green Am- 
boina Butterfly ; and of the Greek division the 
European species called Papilio Machaon or Swal- 
low-tailed Butterfly may serve as an example. 
The remaining sections of the Butterfly tribe 
are distributed according to rules equally inge- 
nious, and by which the student in Entomology is* 
in general enabled to refer each to its proper divi- 
sion j but I shall not at present particularize these, 
but shall proceed to the genus Sphimv. This 
genus is distinguished by the slightly angular or 
prismatic form of the antennae or horns, which are 
generally short in proportion to the animal; and 
by a peculiar thickness of the body, which in 
most term.inates in a point. The name of Sphinx 
is applied to this genus from the favourite posture 
often assumed by the Caterpillars of many species; 
which have a habit of slightly raising the fore-part 
of their body in such a manner as to bear some re- 
semblance to the figure of the Egyptian Sphinx. 
In this genus are many insects of great beauty and 
elegance ; particularly among the exotic species. 
Most of their Caterpillars undergo their change 
into chrysalis at a considerable depth beneath -the
