"A small genus inhabiting the warmer regions of the world. Larva with rather scanty hairs, some finely branched."--(Meyrick.) Represented in New Zealand by a single species of wide distribution. UTETHEISA PULCHELLA, L. (_Deiopeia pulchella_, Meyr., Trans. N. Z. Inst. xxii. 217.) (Plate IV., fig. 3.) This species was first observed in New Zealand in February, 1887, when I captured a single specimen in the Wainui-o-mata valley. Since that time Mr. A. Norris has seen two others near Petone, one of which is now in his collection. All the specimens at present noticed have consequently occurred in a very restricted portion of the Wellington District, though it is probable that the insect is far more generally distributed throughout the country than these records would seem to indicate. The expansion of the wings is about 1¼ inches. _The fore-wings are white, with five irregular transverse rows of oblong crimson spots, alternating with six irregular rows of small black dots._ The hind-wings are white, irregularly clouded with black on the termen; there are two small black spots near the middle. The body is white; the head and thorax are spotted with crimson, and the antennæ are black. The larva is thus described by Newman:--[6] "The ground colour is leaden with a covering of black hairs; there is a broad white stripe down the back, and on each segment down the side is a double scarlet spot. On the continent of Europe this caterpillar is said to feed on the forget-me-not (_Myosotis arvensis_)." In New Zealand the moth appears in February. Mr. Meyrick remarks[7]:--"It is probably only an occasional immigrant. Although a feeble-looking insect, it possesses extraordinary capabilities of flight, and is sometimes met with far out at sea. It occurs throughout Europe, Asia, Africa, Australia, and the Pacific Islands." It is well known to {4}English entomologists as a great rarity, and many discussions have taken place at various times as to the propriety of retaining it on the list of British Lepidoptera. Genus 3.--METACRIAS, Meyr. "Tongue obsolete. Antennæ in [M] moderately bipectinated throughout. Palpi rather short, hairy, concealed in rough hairs of head. Thorax and femora densely hairy beneath. Anterior tibiæ with developed spine beneath, and apical hook. Fore-wings with vein 2 from 2/3, 6 from point with or out of 9, 7 and 8 out of 9, 10 sometimes connected with 9 at a point above 7. Hind-wings with veins 3 and 4 almost from point, 6 and 7 from point or short-stalked, 8 from about 1/3. Wings in [F] rudimentary. (Plate II., fig. 1 neuration of fore-wing, fig. 2 ditto of hind-wing.)
