582 AN INTRODUCTION TO ENTOMOLOGY 



AA. The Frenate Lepidoptera. — Moths, skippers, and butterflies in which the 

 two wings of each side are united by a frenulum or by its substitute, a large 



humeral area of the hind wings, p. 596 Suborder Frenate 



B. The Generalized Frenate. — Moths that are supposed to retain more 

 nearly than other Frenatae the form of the primitive Frenatas, those that 

 were the first to appear on earth. 



C. The Aculeate Frenate. — Moths in which the aculeae are distributed 

 over the general surface of the wings. 



The Incurvariids. p. 598 Family Incurvariid^ 



The Nepticulids. p. 600 Family NEPTicULiDiE 



CC. The Non-aculeate Generalized Frenatae. — Moths in which the 

 aculeae are confined to small areas of the wings or are absent.

BB. The Specialized Frenate. — Moths, skippers, and butterflies that de- 

 part more widely than do the Generalized Frenatae from the primitive type of 

 Lepidoptera, being more highly modified for special conditions of existence. 

 An indication of the specialized condition of these insects is the modified 

 form of the wings. In nearly all the base of vein M has been lost and the 

 branches of this vein joined to veins R and Cu. 



C. The Specialized Microfrenat^e. — Frenulum-bearing moths which are 

 usually of small, often of minute, size. In. many of these moths the anal 

 area of the hind wings is not reduced, having three anal veins; in some 

 others the hind winga are very narrow and a broad fringe acts as a sub- 

 stitute for the membrane of the anal area.
