line divided by a band of bistre brown patches ; median bar M^ — SM^ straight or 

 distally convex ; costal median bar of hiudwiug 3 or 4 mm. more distal than bar

 in mijcerina ; anal angle less produced.

<? . Body as in Ck. zelica ; antennae chestnut. 



i. Wings, iipjicrside blue black as in mycerina ; an azure blue band from near 

 apex of forewing to SM^ of hindwing which it reaches in middle, the band nearly 

 straight, reaching internal margin of forewing 9 mm. from end of SM^, separated, 

 on the forewing, into more or less rhomboidal patches, patch R' — R^ abont 2i mm. 

 in width, the others slightly broader, a minute dot before R\ on hindwing the band 

 narrows towards costal margin, being 5J mm. broad along M- and 2i mm. at SC^. 



Forewing : a small discal spot R'— R^ 4 mm. from cell, blue, seldom preceded 



by another spot ; outline of wing as in zelica, but outer margin more concave in 



posterior half Hindwing : a series of submarginal dots, dots C— R' white, edged 



with pale blue, the others minute, blue ; vestiges of a blue admarginal line. 



Underside vinaceous cinnamon, shaded over with glossy grey ; a rather heavy 

 line of burnt umber colour, faintly bordered black proximally in some places, 

 extends from end of SC of forewing to abdominal margin of hindwing, which 

 it reaches 3 mm. from end of SM^, the line crossing SM- of forewing and C of 

 hindwing « mm. from end, slightly curved at both extremities, with two patches 

 of glossy grey scaling proximally at its upper end ; cell-bars of forewing, and 



submedian and median bars of both wings as in zelica, but a little heavier. 



Forewing : outer marginal area less greyish, more pure cinnamon, than rest of 



wing, slightly deeper in tint between SC and M', especially near margin. 



Hindwing : a series of minute, white, submarginal dots, upper two the largest, the 

 last two accompanied distally by a black dot each ; no tails, outer margin very 

 faintly toothed at R', anal angle somewhat prodnced, but rounded. 



?. Unknown. 



Length of forewing : $, 38 mm.
