NEMOTOIS] TINEIDAE 797 



England to Cumberland, rather local ; C. Europe ; 6. Larva 

 variously stated to feed on Xwittiosa or Sedum. 



3. N. minimellus, Z. 11-14 mm. Head in < black, in $ 

 ferruginous. Forewings golden - bronzy, becoming coppery 

 posteriorly, base more brassy; a blackish basal dash beneath 

 costa ; a very obscurely marked violet-brownish postmedian 

 shade. Hindwings dark purplish - fuscous, in $ sometimes 

 whitish except apex. 



Britain to the Clyde, local ; C. Europe; 7. Larva whitish ; 

 head and plate of 2 black ; 3 and 4 grey above : in seed-heads, 

 afterwards in flat cases of leaf -fragments on leaves of Scabiosa 

 succ isa and S. columbaria; 9-4. 



4. N. fasciellus, F. (*chi/ermillerella, Schiff.) 13-14 mm. 

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

 coppery, base brassy-bronzy; a short black subcostal dash near 

 base; a blackish- violet fascia beyond middle, dilated towards 

 costa. Hindwings dark fuscous. 



Kent, Suffolk, Cambridge, local ; C. Europe ; 7. Larva 

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

 grey spots : on seeds, afterwards in flat cases of leaf -fragments 

 on leaves of Ballota nigra ; 9-4. 



9. MICROPTERYGINA. 



Forewings with an oblique membranous dorsal process 

 (jugum) 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 Lepidoptera, 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 Micropterygidae 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 Hepialidae are an offshoot from the Micropterygidae (with 

 considerable extinction of intermediate forms), constituting a 

 separate line of development quite unconnected with any other 

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