tific will be ever ready to give it the firft place as a Britith Papilioy 
and to thofe a figure of the Caterpillar and Chryfalis will be an ac- 
ceptable acquifition. It derives the title of Purple High Flyer, as 
it very rarely defcends to the ground; except in fome few inftances, 
it has never been taken but in the moft elevated fituations, and even. 
thofe inftances have been after a ftrong wind, or heavy rain: The tops 
of the loftieft foreft trees afford it an afylum, and in the Caterpillar 
and Chryfalis ftate, it is preferved from the wanton cruelty of man, by 
the almoft inacceffible height of its habitation. They feed on the 
Sallow, falix caprea, and the Caterpillars are obtained by beating the 
branches of the tree with a pole twenty or thirty feet in length ; it 
_ is then but a neceflary precaution to cover the ground beneath with 
large theets to a certain diftance, or the infe@ts which fall, will be lof 
among the herbage. 
It is in Caterpillar about AZay and Fune ; it paffes to the Chryfalis 
flate, and in Fuly or Augu/? is a Papilio. 
The great difficulty and trouble to rear the Caterpillars, when found; 
and greater difficulty to take the Fly, has ftamped a valuable conff« 
deration on it, and particularly fo when fine, and a high price is but 
efteemed an adequate compenfation for it if in good prefervation, 
‘The male is fmaller, but more beautiful than the female ; the upper 
fide of the wings of the female not being enriched with that vivid 
change of purple which the male pofleffes in fuch an eminent degree ; 
but the underfide of the female is far richer in the various teints of 
colour-than the male : they are both: beautifully fpotted, mottled, and 
waved with brown, black, white, and orange. The Chryfalis is of a 
very delicate texture, much refembling thin white paper, and is tinged 
in feveral parts with a very lively purple hue which it borrows from 
the wings of the enclofed infect, and bears the charatteriftic mark 
of a Papilio, by being fufpended from the tail, with the head downward,
