Upper Side. The head is wanting. Thorax blueish black. Abdomen very dark blue, with five 

 small white spots on each side. Anterior wings black, with a number of small spots dispersed all f)ver 

 them, whereof five next the body are yellow, the rest white. The nerves, from the middle to the extre- 

 mities of the wings of a dark red, or crimson colour. Posterior wings at the base of a blueish black, but 

 along the external parts deep mazarine blue ; whereon are placed twelve faintish white spots. 



Under Side. Nearly corresponds with the upper, except in the number of spots, which are more 

 numerous ; some being surrounded with blue, those next the external edges being double. The crimson 

 colour on the ribs of the superior wings is wanting on this side. All the wings are entire. 



Notwithstanding the imperfect state of this insect, it is evident that it is nearly allied to 

 many other species figured by Drury (including those represented in PL 11. fig. 4., PI. 6. 

 fig. 4., PL 11. fig. 3.), and which appear to form the connecting links between the 

 aberrant Sphingidae (Zygsenida^) and the Arctiidse. The singular neuration of the upper 

 wings of this insect is nearly similar to that of a remarkable Indian species, which I have 

 described and figured in Mr. Royle's work on the Natural History of the Himalaya.
