Typ 



Proboscis fully developed ; palpi upturned, the 2nd joint fringed with 

 long hair in front, the 3rd somewhat porrect ; frons with truncate conical 

 prominence with raised rim at extremity and flattened plate below it ; antennse 

 distinctly or strongly dilated towards extremity ; tibiae fringed with rough hair 

 above ; abdomen with dorsal crests and lateral tufts ; male with protrusible 

 lateral tufts of long hair from base. Fore wing in female with vein 3 from 

 near angle of cell ; 5 from above angle ; 6 from upper angle ; 9 from 10 

 anastomosing with 8 to form the areole; 11 from cell; male with a large 

 glandular dilation on costa beyond middle, vein 12 being curved downwards 

 round it, below vein 12 is an elongate semicircular patch of ribbed membrane, 

 a clicking sound being produced probably by friction with the tai-sal spines ;

 curved downwards, the areole long and narrow, and veni 10 strongly anasto- 

 mosing with 8, 9. Hind wing with vein 2 from towards angle of cell ; 3, 4
