angulatecl at the origin of vein 4 internally, and rather less so 

 externally on vein 6 ; between the costa and these two points the 

 band is much the widest and best defined ; discoidal dot black ; a 

 dark cream patch on the costa beyond the fascia ; some dark blackish 

 suffusion towards outer margin. Hind wing similar ; a broad basal 

 fascia composed of several black-irrorated lines ; no dusky suffusion 

 on margin.

Proboscis well developed; palpi porrect, the 3rd joint to well beyond 

 frons, half as long as 2nd and naked ; 2nd joint clothed with stiff 

 hair. Antennae simple, rather short, barely longer than half costa ; 

 hind tibia? with short spurs. Abdomen in 9 not reaching beyond 

 secondaries. Forewing with veins 3, 4 from angle of cell, vein 3 

 almost straight ; vein 5 equidistant from 4 and 6 ; 8 and 9 and 10 

 given off from 7 ; vein 5 extending into cell as a veinlet ; a slight 

 fold in the wing between 4 and 5 ; a branch veinlet within the cell 

 coincides with this fold at cross vein of cell. Hind wing, vein 2 from 

 frds from base of cell ; 3 before end of cell ; 4 from angle ; 6 and 7 

 on a long stalk ; 8 soon after leaving base anastomoses with 7 for 

 a considerable distance.

Forewing lightish olive-green with black markings ; four toler- 

 ably well-defined lines traverse the wing ; the basal line consider- 

 ably angled in middle ; second line composed of a costal patch, a 

 somewhat elongated mark lying within the cell and an ill-defined 

 patch on the inner margin ; situated between this line and the post- 

 medial line on the costa is a well-defined black mark ; the post-medial 

 line, clearly defined on costa, very slender, composed of dark dots to 

 vein 2 and thence to inner margin with an irregular patch of black ; 

 a fourth line commences with three distinct spots and then by an 

 indefinite number of marks is continued to the inner margin ; dis- 

 coidal spot black, elongated. Hindwing orange-yellow with a rather 

 narrow grey marginal band, the orange colouring continued to 

 margin between veins 3 and 4. Underside of both wings orange; a 

 large blackish patch at apex of forewing. 



Expanse 30 millim.
