acls in perfect unifon with the reft ; in moil winged Infers we find 

 the tendons of each wing united by ftrong membranaceous webs, 

 which prevent any one from acting without the others, but in this 

 every tendon muft perform a diftindt part, and yet perfectly in 

 conformity with the reft to ailift the Infect in its flight. When the 

 Infect refts the feathers fold over one another ; but when it flies, 

 they are thrown open, and refemble a full expanded fan. 



The natural fize of this fingular. creature is given at Fig. i. and 

 as a more correct figure than can be fhewn in fuch a fmall compafs 

 was thought neceflary, its magnified appearance is reprefented at 

 Fig. 2. 



The plumes of this Infect differs fo much from thofe of other Moths, 

 that we have alfo added, at Fig. 3, the appearance of the upper part of 

 one, as feen by a very deep lens of the Microfcope ; by this the ftem 

 or quil is obferved covered with fcales of the form ufually found on 

 other Moths, but the fides are finely feathered with long hairs, in 

 tufts, alternately of a light and dark colour, and which, owing to 

 the minutenefs of the Infect appear like patches of an uniform 

 colour, before it is examined with the Microfcope. 



This Infect is not uncommon in Summer, it flies about hedges 

 in the evening.
