 base, white at extremity, the lateral tufts on terminal segments 

 and the anal tuft black. Fore wing deep chocolate-brown ; an 

 oblique medial series of conjoined spots ; a postmedial maculate 

 band from extremity of the hyaline membrane to tornus interrupted 

 at vein 2 ; a terminal series of white points. Hind wing orange ;

$ . Head and thorax black, the latter with a blue gloss ; palpi 

 at base and extremity of 2nd joint, sides of frons, back of head, a 

 rim behind eyes, tegulse at middle and sides, and patagia at base and 

 extremity with pale yellow spots : antennae white at tips, towards 

 which they are moderately dilated ; tufts of orange hair from femora

 costa and beyond lower angle of cell ; diffused patches of scales 

 below end of cell and on inner area ; cilia chequered black and 

 white. Hind wing orange : a small discoidal black spot ; a terminal

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

 hair in front, produced at extremity to an acute angle, the 3rd joint long, 

 naked, and somewhat porrect ; frons with truncate conical prominence with 

 raised rim at extremity; antenna almost simple, strongly dilated at extremity ;

 5 from just above angle ; 6 from upper angle ; 9 from 10 anastomosing with 8 

 to form a short areole, 7 from end of areole ; 11 from cell; male typically 

 with a more or less developed stridulating organ below costa beyond middle, 

 the veins being curved downwards. Hind wing with vein 2 from towards end 

 of cell ; 3, 4 from angle, 5 obsolescent from middle of discocellulars ; 6, 7 from
