Form III. — Pterophorid.5. 



Head often with forked scales, forehead smooth or with conical 

 horny prominence or tuft of scales, ocelli usually obsolete. Tongue 

 developed. Maxillary palpi obsolete. Forewing with 5 remote from 

 i, neuration often much degraded, usually cleft into two (rarely three 

 or four) segments. Hindwing with 5 remote from 4, 7 remote from 6 ; 

 lower surface with a more or less developed double row of dark spine- 

 like scales on low-er margin of cell ; wing usually cleft into three seg- 

 ments. Cilia containing ramified hair-scales. 



This is one of the two groups of Microlepidoptera covered by the 

 popular term " Plume-moths," the wings being cut by longitudinal 

 clefts into indistinct segments which in some genera have a feathery 

 appearance. On this account the members" of this group are generally 

 easy to recognize, but there is one section (the Agdistinoe) in which 

 the wings are not cleft, although even here there is some dimiiuition 

 of scaling on the areas which are develo])ed into clefts in the other 

 sub-families. 



The Pterophorida; are easily separated from all other Lepidoptera, 

 however, by the series of spine-like scales on the lower surface of tjip 

 hindwing. 



The family is usually considered as belongiiig to the Pyralidina 

 and has some PjTralid affinities, but it is very isolated and it is prcbab'y 

 better to treat it as a separate entity. 



Larva rather short, usually with well developed fascicles of hairs 

 in the free-living forms, but these are necessarily much reduced in the 

 case of internal feeders. As a rule the larvaj seem attached to composit e 

 plants, feeding on the flowers and fruits but in a few cases they tunnel 

 in stems or fleshy fruits. Pupa usually hairy, attached by the tail by
