4. N. fasciellus, F. {schiffermillerella, Schifl'.) 13-14 mm. 

 Head in $ black, in $ ferruginous. Forewings shining purplish-

 whitish ; head and plate of 2 black ; 3 and 4 with pairs of dark

9. MICROPTERYGINA. 



Forewings with an oblique membranous dorsal process 

 (juguni) near base, forming with the dorsal margin a notch or 

 sinus which receives the costa of the hindwings. Hindwings 

 without frenulum, Ic present, with 11 or more veins, neuration 

 essentially almost or quite identical with that of forewings. 

 Forewings and hindwings more than usually remote at origin. 



In the two families which constitute this highly interesting 

 group is fortunately preserved a type of Lejndoptera, whose 

 existence could never have been inferred from a study of other 

 forms. Without a knowledge of these two families the true 

 origin of the Order could never have been more than a matter 

 of more or less probable conjecture. The Micropterygiclae are 

 the primeval ancestors of all the Lepidoptera, indicating their 

 origin from the Trichoptera so nearly that one or two more 

 discoveries might make it hard to draw any line of demarcation. 

 The Hepjialidae are an offshoot from the Micropterygidae (with 

 considerable extinction of intermediate forms), constituting a 

 sejDarate line of development quite unconnected with any other 

 Lepidoptera ; if, as is possible, this separate stem may have
