■with one or two thin lines in front ; the postdiscal spots all well separated, spot 

 R' — R^ 5^ mm. and spot M' — M- 6 mm. from outer margin, the series curving costad 

 anteriorly, on the whole almost parallel to outer margin stopping at M^, spot M^ — 

 (SM') seldom vestigial ; admarginal spots all large, dull ochraceous rufous, often 



paler in middle, spot M^ — SM^ shaded with bluish white at proximal edge. 



Hindwing : basal area rather paler than base of forewing, abdominal fold grey, 

 blackish outwardly, with a grey, ill-defined, rather small patch before anal angle ; a 

 black or dark brown median patch C — R' ; discal band of forewing continued to 

 (SM^), tapering behind, outer edge more or less sinuate between R^ and M^, crossing 

 R' proximal of bent ; white snbmarginal spots transverse; upper ones sometimes 

 obsolete, all shaded and edged with pale blue, this blue scaling extended to patches 

 between R^ and SM- ; admarginal interstices as prominent as in d, interstices C — R' 

 orange buff, the others greenish blue, with an orange buff spot upon internervnlar 

 fold ; snbmarginal bars rather deeper black than disco-submarginal area, bars 

 M' — SM^ more or less isolated, often reduced to mere dots; discal bar C — SC^ some- 

 times vestigial within discal band. 



Underside : spot in apex of cell of forewing, and discal band of patches of both 

 wings creamy white, disco-snbmarginal area of forewing and snbmarginal area of 



hindwing shaded with grey. Forewing : interstitial patches smaller than above, 



spot in apex of cell often small, shaded with drab, postdiscal interstitial spots 

 reduced to lunules, middle ones creamy white, double one M- — SM^ grey ; post- 

 discal bars M^ — SM^ represented by three black, triangular, patches, the last two 

 contiguous, the other postdiscal bars represented by clayish, indistinct, patches ; no 



admarginal spots, or only vestiges of them. Hindwing : discal interstitial band 



much narrower than above, costal median bar in front of median bar C — SC^ ; 

 admarginal interstitial markings C— R' rufous orange, R' — SM- olive buff with 

 gallstone yellow centres ; tails less slender than in <S, upper one slightly spatulate, 

 length 6 to 7 mm. and 5^ to 6| mm. respectively.

The remaining allies of Ch. guderiana with " black " males are a puzzle to
