Note.—The difference in the metamorphosis or transformation and in the 
development of the wings of the eight individual orders of Flies is also 
specified by the following letters: M.I. = Imperfect Metamorphosis. 
M.C. = Perfect Metamorphosis. 
(Compare Gen. Morph. ii. p. 99.) 
A.A. = Equal wings (fore and hinder wings are the same, or differ but 
little). 
A.D. = Unequal wings (fore and hinder wings very different in 
structure and texture, occasioned by strong differentiation).
