Head above flat, fuscous ; beneath flavescent, with a black margin : 

 thorax fuscous, immaculate : tegmina fuscous, exterior margin virescent, 

 which colour, however, does not reach the apex of the wing : there are 

 five black dots along this margin of which the four posterior end in- 

 wards in a fulvous dot : wings sanguineous, fuscous at the apex (Fahri- 

 cius) . 



Head above flat, obscure ; beneath, yellowish, border black : thorax 

 obscure immaculate : tegmina obscure with the costal margin greenish 

 which does not extend to the apex, on this part are five black spots of 

 which the four posterior are bounded internally by a tawny spot : wings 

 sanguineous with the apex obscure {Olivier). Donovan states that the 

 tegmina have a green margin on which there are a few black spots 

 semicircled with orange. Long, 17 millims. 



The Indian Museum possesses a very mutilated specimen.
