61] LEPIDOPTEROUS LARVAE — FRACKER 61 



SUBORDER FRENATAE 



MICROLEPIDOPTERA 



Altho much abused, the term Mierolepidoptera is a convenient one 

 to indicate the smaller members of the Heteroeera. The limits of the 

 group are not now and never can be fixed, for the division is not an 

 entirely natural one. Used here to cover the same families that Dyar's 

 List includes in "TINEOIDEA", it embraces three or more wholly 

 separate groups, no more closely related to each other than some of them 

 are to the Macrolepidoptera. 



The following is an outline of the classification used in this paper. 

 The sources from which it was drawn and the reasons for departing 

 from Dyar's arrangement are given in the introduction to Part Two. 

 It is followed by a brief discussion of the larval characters which bear 

 on the relationships of the group.
