i ? . Palpi above black ; head, ])ronotnm, and anterior part of mesonotum 

 rafons chestnnt, meso-metonotnm and l)ase of, in ? the whole npjierside of, abdomen 

 drab brown, rest of abdomen and underside white. 



£?. Wings, uppcrside. Fore wing : base as far as origin of M' rnfoas 



chestnnt, this area horizontally ent off or sinnate in cell, distally separated by black, 

 proximally ill-defined, more or less heavy, median bars from a broad creamy 

 white discal l)and ; the baud abont 18 mm. wide at internal margin, 11 mm. distant 

 from base, patch M^ — SM" of nearly the same length, bordered grey proximally and 

 distally, patch M' — M- mnch smaller, obliquely concave distally, patch R' — M' 

 isolated, the wing being black, about 2 to 3 mm. from base of M', spot R^ — R' again 

 smaller, discal patches SO* — R^ 8 mm. from cell ; a series of five or six postdiscal 

 spots, also white, spot SC^ — SC° absent or minute ; a white admarginal spot upon 



(SM'), sinuate distally ; fringe white at ends of internervnlar folds. Hiudwing : 



creamy white, base blackish for abont 4 mm., this colour gradually shading into 

 grey distally ; a series of black snbmarginal bars, well separated from one another, 

 mostly somewhat concave proximally, shaded at edges with olive grey, bars Sf? — R' 

 sometimes rather feebly marked ; a thin, black admarginal line, contiunons or 

 subinterrnpted at internervnlar folds ; abdominal fold slightly shaded with grey, 

 more white, less cream colour than disc. 



Underside : chalky white, slightly glossy, bars very thin. Forewing : cell- 

 bar 3 absent, bar 2 very oblique, partly obliterated, bar 4 nearer M" than M', angled 

 in middle, the angle pointing distad ; snbmedian bars M' — (SM') one in front of the 

 other, 2 mm. from base of M.' ; median bar M- — (SM') 2 mm. distant from the sub- 

 median bar ; median bar M' — M" 1 or 2 mm. more distal, concave distally, | to 

 1 mm. distal of base of M', bar R^ — M' oblique, 4 or 5 mm. from base of M', bar 

 R^ — R^ close to bar D, parallel to it, distance about ^ mm., bar SU* — R' 7 mm. 

 from cell, oblique, bar R' — R^ very little more distal, sometimes convex distally ; 

 discal bars SC!'^ — M^ more or less vestigial, especially the posterior ones, bar M^ — SM^ 

 fused with the postdiscal bar to a large black patch, which includes some white 

 scales near proximal edge as vestige of the white discal border of the discal bar ; 

 the other postdiscal bars not represented, but the postdiscal interspaces occupied by 

 white spots as above ; outer two-thirds of wing more glossy than base and internal 



marginal area. Hindwing : basal and subbasal costal bars absent, snbbasal bars 



C — M vestigial or absent ; snbmedian costal bar about l^mm. from PC, much more 

 basal than the snbmedian bars C — M ; median bars more proximal than in the 

 allied species, the series almost straight, but interrupted at veins, bar R'' — W very 

 close to bar D, bar R' — M' absent, bar M'— M^ midway between M' and M^ no 

 median bars M^— SM^ ; discal bars concave distally, except the last ones, very much 

 heavier than the other bars, forming a continuous series which extends in a straight 

 line from costal to abdominal margin, crossing M' about 1 mm. from base and 

 C 15 mm. from end of these veins, the bars edged white distally, contiguous with 

 a postdiscal, rufous chestnut band of 2 mm. width, the band shar])ly defined, 

 irregularly concave between veins distally, except between M" and SM^ with 

 vestiges of black postdiscal bars at outer edge, especially behind ; black submarginal 

 dots R' — SM- minute, dot SC^— R' sometimes vestigial ; admarginal interstitial 

 spots, primrose yellow, extremely pale, spots C — R' sometimes ochraceous ; a
