 olivo-groen, exeept fringe. Underside ochreons, paljnis near tip and forebreast 

 anteriorly olivo-green, upperside of tibiae anil tarsi grey, onter lateral surface of 

 inidtibia and -tarsus greenish brown. 



^V'ings, above. Forewing : silky bufifisli grey ; in shape similar to that of 



asttji/onus, markings olive-green (costal ones jiartly faded into ochraceons), eight or 

 more feeble costal bars from base to apex of cell, the inters])aces partly filled in with 

 olive at costal margin, a costal patch a little way beyond tip of cell, sliarjily limited 

 behind by W^, gradually fading away distally ; between fork and ajjcx a similar 

 patch bordered by SC'"", along whicli the colour extends to outer margin, a subajiical 

 costal triangular spot an oblique subbasal band twice as long as broad, from 

 (SM') to inner margin, a narrower band between SM- and inner margin, witii which 

 it stands at right angles before middle, a nearly seuiicircular large patch upon the 

 inner margin between middle and distal angle, reaching nearly M', consisting of 

 blackish markings behind, and being green before M- ; a brown apical semicircle 

 SG^ — SC'', a brown submarginal line from tip of SC^ to tip of SM-, broadly 

 bordered proximally with greenish olive, marginal space between band and edge 

 of wing purple brown ; a large ovate blackish stigma, a straight line behind 

 SC^-' just proximal of fork, a deeply curved very faint line R^ — R' behind it, a little 

 more jiroximal, a trace of another similar line nearer cell, and between this line and 

 cell a broader line shining through from below ; traces of two lines in front of 



second inner marginal band as prolongations of the respective costal bars.- 



Hindwing : maize yellow, grey at base and abdominal margin, in ? shaded with 

 tawny ; apex acute, distal margin faintly concave in front, more obviously so 

 behind ; a straight, dentate, brown line shaded a little with ochraceons, aliout 

 1 .1, mm. outside cell at R^, ending behind in a spot, a thin brown line between it 

 and marginal band, faintly broken, evenly curved in front, a brown ujarginal band 

 sharply defined, less so at ajjex of wing ; an anal submarginal band confluent 

 with it. 



UiiJcn<i(Ie similar to upperside of hindwing, bright maize yellow, shadi'd 

 with tawny in ? ; stigma vestigial ; a tawny brown line outside cell obtusely 

 angnlate at R^, rather heavy in front, where it is deeper brown ; Ri and onter half 

 of SC brown ; a very broad brown marginal band pointed at tip of S(J\ and 



linear from M' backwards, Hindwing : first discal line in position as above, 



ciu'ved in front, a jiostdiscal line as above, liut there are traces of other lines 

 between the two ; marginal band sliaded with grey, in S almost restricted to 

 extreme edge and j)urj)le brown in colour, more distinct in ?. 



S. Sexual armature similar to that of astij(/o)i(is, but fi'ietion-patt'li broader, 

 tooth of harpe strongly pointed, tenth sternite less broad.
