Head, thorax, and abdomen all reddish grey like wings ; the abdomen paler

 wet season (Ockenden). 



This species is remarkable for the absence of teeth and excision in the 

 hindmargius of wings ; in forewing the hindmargin is Bhortly indented below 

 apex, then evenly gibbons, passing into the convex inner margin with only a 

 faint bend at anal angle ; the hindmargin of hindwing is well rounded throughout.

Forcidng : pale ochreons, striated and suffused with dull chestnut ; the lines 

 thick, dark chestnut ; first from before middle of costa, obliipie inwards and slightly 

 curved, to two-fifths of inner margin ; outer line from two-thirds of costa, oblique 

 outwards to vein 7, then angled and oblique inwards, slightly flexuous to two- 

 thirds of inner margin ; an oblique chestnut mark on discocellular meeting 

 outer line ; space between the two lines whitish ochreons, rounded above and 

 bounded by the cell-mark and vein 6 ; basal area striated with chestnut ; 

 marginal area suffused chestnut, forming a triangular blotch on hindmargin, 

 with the apex at the discocellular, the costal area and a small spot at anal 

 angle remaining paler ; traces of a darker submarginal line on costa and before 

 anal angle. 



Hindwing : costal area yellow, the rest suffused with chestnut ; a thick 

 diffuse median line; a submarginal shade, plainest at costa and anal angle. 



Underside like upper.

Cell longer than half of wing ; vein .5 from aliove middle of discocellular ; 

 7, 8, 9, 10, 11 all stalked from two-thirds: in hindwing vein 7 well before end

194. Spododes basipunctata spec. nov. 



Forewing: pale testaceous, tinged with olive-grey, and densely powdered
