 or three expansible enormously enlarged shuttle-shaped pearly 

 scales (|- length of wing) from towards base lying along costa above, 

 and a very large elongate chitinous process projecting obliquely 

 from costa near base, beneath black and concave to receive a fine 

 pencil of long hairs, partially covered beneath by a fringe of much 

 enlarged flat pearly prismatic scales, the remainder covered by a 

 fringe of very long scales projecting downwards from beneath costa 

 of forewings on basal f .
