T he caterpillar feeds on th e Black Haws, Saffafras, Plum, &c. I t lpun on the
21Û o f September, and th e moth appeared Ju ly 18 th. This Ipecies always fhapes
its web or cocoon as in th e figure, fattening it to a twig. T h e flat end opens and,
fliuts like a door, and is fitted w ith th e greateft exaétnefs. T h e infe<ft continues in
this web all w in te r in th e worm ftate, n o t changing to a chryfalis till w ith in a
fhort time o f its final transformation into a fly. T h e caterpillar is lhaped like the
ro o f o f a houfe, th e hairs riling on each fide gradually to a ridge down the middle
o f its back.
This and the following have fome flight agreement with the defcriptions of Bhahena ful-
phurata and cerata of Fabricius, Entom. emend. Vol. 4. 207, 208, fuppofing. thofe defcriptions
to have been made from female infects, without any knowledge of the other fex or their oeco-
nomy; but we cannot conceive that fo intelligent an entomologift could, even fo circum-
ftanced, have taken thefe moths for geometra, and therefore prefume they are hitherto totally
nondefcript fpecies.
