$ Yelloiu-ochrcous ; the Jiind-iuing, and in a less degree the fore- 
luing, i7i the central j)art "paler and luith a creamy-pink tint ; bases and 
hind-mar gincd borders black ; a disced series of black spots. Fore-wing : 
basal black well marked, bat seldom extending as far as the middle of 
discoidal cell, where there is an elongate black spot ; costal edge at 
base ochreous, but thence very thinly black to near apex ; apical tip 
broadly black, but hind-margin from extremity of third median nervule 
with only a linear edging ; a narrow irregularly-shaped spot at extremity 
of cell ; a little beyond it an oblique well-marked bar of five spots, of 
which ^our are united and the fifth separated from the fourth by the 
third median nervule ; beyond this bar, in some specimens, a more or 
less ill-defined dusky suffusion extending in the form of a curved 
transverse fascia towards posterior angle ; usually a submarginal row 
of three inter-nervular spots between third median nervule and sub- 
median nervure ; of these, the uppermost spot is very often and the 
second sometimes wanting ; below extremity of cell, two small spots, 
one above and the other below first median nervule ; below median 
nervure a small rounded spot just on the edge of basal black. Hind- 
wing : basal black narrow, wider below median nervure ; a spot in cell, 
just beyond basal black ; a smaller indistinct spot on edge of cell a 
little beyond and above the last ; an irregular discal row of seven small 
spots, often rather indistinct ; a broad hind-marginal black border, 
without spots, with its inner edge slightly suffused ; ground-colour 
clouded with a dull-red tint near this black border. Cilia grey.

hind-iving and apiecd region creamy -lohitish., the former varied with
