{38}_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 over them, whereof five next the body are yellow, the rest white. The nerves, from the middle to the extremities 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., Pl. 6. fig. 4., Pl. 11. fig. 3.), and which appear to form the connecting links between the aberrant Sphingidæ (Zygænidæ) and the Arctiidæ. 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.
