Front rather imiTower anteriofly than in A't'/iioria. Palpi rather larfo, 

 projecting well in advance of the front, the second joint rather large and 

 bushy. Male anleiiu;x; with rather long pectinatiuns, terniinal fourth .simple; 

 in the female .simple, finely serrated. Fore wiiig.s with the costa straight, the 

 apex rather obtu.se. Hind wings much rounded. Frinire on both win<rs 

 unusually long. Venation: the costal region is rather wide, the ,sul)c»).stal 

 cell is sometimes open (chlorokucarid); the posterior diseal veiude is very 

 ol)li(pu', but not iiuieh curved; the oiigin of the lirst median venide is a little 

 removed from that of the second, w bile in Nriiioria the origins of the two are 

 blended. Hind legs: tibi;e long, with a large brush of iiairs; tarsi oiK'-liiird 

 to one-half as long as the tifi;e {rlilorukucuria). or a little l(tii;rer than the

 green, with white firm lines, the outer common to both win<is, broad and 

 cons])iciious; fringe whitish, rarely deep red.
