OUR OPINION OF IMITATION. 129 



For example, if the insect imitated be of a warm 

 or reddish hue, that colour must enter prominently 

 into the composition of its artificial imitation, but 

 not necessarily in the same identical part. In the 

 natural insect it may be the body or legs which 

 have this colour prominently, but enough will 

 have been done with its " counterfeit present- 

 ment" if it be found sufficiently predominating in 

 the whole production, no matter whether displayed 

 in the legs, or body, or elsewhere. The same 

 with every other hue. 



It is perhaps important that the character of 

 the wing be attended to as regards its opaqueness 

 or transparency ; and it may be remarked on the 

 form of the artificial fly, that as it is impossible to 

 dress it sufficiently delicate to equal nature, it 

 becomes necessary to exaggerate some parts, so as 

 to produce a proper harmony and proportion in 

 the general form ; as, for example, making the 

 wing longer, it may be, than the natural wing, in 

 order that the fly may appear more elegant and 

 bear a more correct proportion to a body unavoid- 

 ably thicker, from the nature of its materials, than 

 thafc of the natural fly. 



So much for the general principles on which 

 we suppose the imitation of natural flies to be 

 founded. We have already expressed our opinion
