Its Wings are of a pale dufky yellow ; the rib of them is feen beau- 

 tifully jointed -, and is palpably hollow. 



The Scales, which make what are call'd their hairs, or feathery 

 fubftance, are very numerous, narrow, and fharp, both at the edges, 

 and the point ; and they make a great appearance, becaufe, each be- 

 ing compos'd of two feathers, the creature feems, in comparifon 

 with the preceding, to have four wings upon each fide. 



The creature has, when living, all the motions of the preceding 

 kind, but ftronger ; as its Body feems more mufcular : and the power 

 it has of raifing its Briftles, as the Porcupine, muft add greatly to 

 the irritation, when it is got into a tender part. 



Whether, and how far, head-achs are to be traced from thefe little 

 creatures, is a fubject yet for more enquiry ; but 'tis worth the pains. 

 Many have this pain from the fmell of Flowers. Some have 

 been found dead, with quantities of violets, and other Flowers, in 

 their chamber. Phyficians have attributed thefe deaths to the power- 

 ful odour of thofe Flowers ; but that they mould be owing to thefe 

 creatures, is much more probable. 



Whether they do, or do not, ever fly far from the Plants they in- 

 habit, I have not yet found ; but in the ftillnefs of the night, it 

 would not be ftrange if they mould : and that they hover round 

 them I have feen : for placing a iiiung light, and a great convex 

 glafs* near a pot with a growing Lupine, in a dark chamber, I have 

 difcovered the air, all about the tops of the Plant, in a manner filled 

 with them, moving like motes in a fun- beam.
