Four days after I again visited that spot and Urtica shrub for the last time that season (as I was to return to Napier the next day), and found 3 more larvæ and 2 chrysalides, and brought them all away. Arriving at Napier on the 2nd May, I placed the larvæ, with a quantity of fresh leaves, in a large white glass bottle; on the 4th, one of the larvæ had suspended itself to the (bored) cork of the bottle; on the 6th it cast its larva-skin and partly took up the chrysalis appearance, but was very wet at first; and on the 7th it assumed the true chrysalis aspect. On the 9th another of the larvæ hung itself to the cork, head downwards, and commenced its transformation. On the 11th one of the chrysalides dropped off from the cork; I had noticed that this one was smaller and of a lighter colour. On the 18th another of the larvæ entered into its chrysalis state, also attaching itself to the cork of the bottle. On the 19th one of the chrysalides I had brought in that state from the forest burst, and the perfect insect emerged; but, owing to the shallowness of the glass in which these forest chrysalides were confined, one wing had got stuck fast to the side of the bottle in the process of emerging, and so became contracted and rigid when dry, like a little plaited epaulette; while the other wing, being free, had attained to its full size and shape; but the poor creature was sadly lopsided. On the 21st another of the forest chrysalides split open, and the imago emerged—a beautiful sight,* See the full description of similar emergence of Danais berenice, as witnessed by me (“Trans. N.Z. Inst.,” vol. x., p. 279). once seen, never to be forgotten. A thing of beauty is a joy for ever. This was a fine and perfect specimen of this butterfly. I regretted much those larvæ that entered into their pupa state here in Napier not emerging therefrom as perfect insects. I suspect this was owing either to their not having been fully fed down to the time of their entering into that state, or that they assumed it too early, and perhaps in an unhealthy state. As larvæ they were very voracious; it seemed as if they were always eating, night and day; so that my stock of Urtica leaves that had cost me so dearly were soon disposed of. On their being used up I tried the hungry creatures with several other leaves of Maori plants, but none would they touch. That shrub itself, though a large bushy and spreading one (about 5ft. high and several feet round), with several others, smaller ones, close by, almost always presented a sorry sight from their leaves being so gnawed and stripped; hence I had always some difficulty in procuring good specimens of it for drying and preserving. Those Urtica plants, however, recovered themselves throughout the winter, and were fully
