Diphthera malachites^ Hampson, Faun. Brit. Ind. Moths, ii. 

 p. 294 (1894). 



This is a beautiful Moth, which was first brought from the 

 Island of Askold, near the mouth of the Amoor, but it has 

 since been found in Northern India. 



The head and front of the thorax are green ; the antennoe 

 and the hinder part of the thorax are rufous, and the abdomen 

 is white, with a tuft of stiff black hairs on the middle of the 

 back. The fore-wings are green, with the half-line, and the 

 two transverse lines white, more or less bordered with black. 

 The basal and central areas are rufous, the former marked below 

 with a black spot, and the latter containing a green spot on a 

 dusky ring near the costa, and greatly extended in the inner 

 margin. Towards the hind margin are two black spots con- 

 taining a white dot, and bordered inside with white, and out- 

 side with buff. The hind-wings are brown, more or less 

 clouded towards the hind margin.
