Somewhat resembles Zeller's Pcedisca chloroticana ; 

 primaries above emerald-green, with a longitudinal irre- 

 gular black streak commencing at the base of the costa, 

 whence it runs obliquely to just below the submedian

 throws off a transverse spur to the dorsal margin and 

 terminates in a furca, partly enclosing a red-brown spot, 

 close to the end of the cell ; costa and dorsal margin 

 black-spotted; outer half of costal margin cream- 

 coloured ; a large black apical patch, united to a 

 cupreous-brown patch near the external angle, the two to- 

 gether forming an imperfect external border ; secondaries 

 whity-brown, slightly more golden towards apex ; fringe 

 white ; head and thorax green, spotted with black ; 

 abdomen pale brown ; primaries below flesh-tinted, 

 slightly green on the basal two-thirds, and with the dis-

 abdominal border ; body pale brown ; palpi green, black
