"Ovum cylindrical or sub-conical, ribbed and often reticulated. Larva with pairs of tentacles or more usually series of bristly spines. Pupa exposed, suspended by the tail, often angular or with metallic spots."--(Meyrick.) (See Plate III., figs. 1, 2, and 3 larvæ, 27, 31 and 32 pupæ.) We have three genera represented in New Zealand:-- 1. ANOSIA. 2. VANESSA. 3. JUNONIA. Genus 1.--ANOSIA. "Eyes glabrous. Club of antennæ elongate, gradual. Fore-wings with vein 10 separate. Hind-wings with transverse vein present." (Plate I., figs. 7 and 8, neuration of _A. erippus_.) "A genus of moderate extent, generally distributed within the tropics, with two or three species ranging beyond them. Imago with termen of fore-wings sub-concave. Larva with pairs of long tentacles. Both larva and imago are protected by a strong nauseous scent, or taste, and are uneatable to birds."--(Meyrick.) We have two species in New Zealand. ANOSIA ERIPPUS, Cr. (_Papilio archippus_, Fabricius, Spec. Ins., p. 55, n. 243 (1781). _Danais archippus_, Butler, Butterflies of N. Z., Trans. N. Z. Inst. x. 265. _Anosia plexippus_, L.) (Plate XI., fig. 1, fig. 2 under side; Plate III., fig. 3 larva, fig. 27 pupa.) This handsome insect has occurred from time to time at various localities in both the North and the South Islands, but does not appear to be generally common. Particulars of the early captures of this butterfly are thus given by Mr. Enys[44]: "First recorded as a New Zealand insect by Mr. Fereday, in a paper read before the Canterbury Institute, January 2, 1874, and printed in vol. vi. of 'Transactions.' Mr. Fereday received the butterfly from F. H. Meinertzhagen, of Hawkes Bay. Dr. Hector also obtained it in Westland. It has also been caught near Auckland. In vol. xi. of 'Transactions' Mr. F. W. Sturm records that he first saw this insect, or a closely allied one, at the Reinga, up the Wairoa River, Hawkes Bay, December, 1840, or January, 1841. In 1848 he captured a number at the Waiau, a tributary to that river. Again in 1861 he captured three on the Rangitikei River near Mr. Birch's run. He also records other captures." From these records it will be seen that the insect was observed as early as 1840, and it thus seems scarcely probable that it was accidentally introduced by man, as Mr. Butler appears to suppose.[45] Recently _A. erippus_ has occurred many times in the neighbourhood of Cook's Straits. In 1879 several specimens were bred from larvæ found by Mr. C. W. Lee near Wangaehu. In 1881 I captured two specimens near Nelson and saw three others. In 1890 two specimens were taken by Mr. R. I. Kingsley, and in January of the following year I captured two more, all near Nelson. During the autumn of 1892 {103}one specimen was taken near Otaki by Mr. Rutherfurd, and several others were seen. The same year a specimen was also taken by Sir James Hector at Petone. In 1896, I understand from Mr.
