Family Ichneumonidæ.
Sub-Family Pimpilinæ.
Genus Rhyssa

Rhyssa clavula,965 sp. nov.

Female: Abdomen a rich dark-red-brown variegated with yellow: thorax, antennæ (basal ⅔), ovipositor and its sheaths much darker brown almost piceous.

Head: orbits of eyes and post-clypeus yellow; two vertical ferruginous lines from base of antennæ to mouth; three ocelli in dark central band a little above the eyes; antennæ filiform, curved, 13 lines long, finely annulate (above 50 joints), and under a lens covered with excessively minute whitish lines, very slightly and finely hairy, basal joints knobbed with yellow margins, the lowest the longest, apical third flavescent, the 3 apical joints light-ferruginous: clypeus dark-margined, enclosing a light-ferruginous triangular spot having a transverse red line, and a shorter brown one above it; labrum dark almost piceous (this dark band also surrounds the mouth); palpi light ferruginous.

Thorax: the mesothorax transversely and finely ruguloso-striate; a large semi-curved triangular yellow spot on pleuræ of prothorax, another below junction of anterior wings, a smaller one above the junction (transversely barred with a narrow dark band), the bases of the wings, the scutellum, post-scutellum, and the apical portion of the metathorax (encircling [159] the insertion of the abdomen) yellow: wings, iridiscent, infumated, hairy at bases, and sparsely sprinkled with very minute hairs; principal veins reddish-brown, cross veins blackish. Legs: all the femora, and the coxæ and tibiæ of posterior pair, very dark ferruginous; the coxæ of the two anterior pairs and all trochanters yellow; all the tarsi, and the tibiæ of the two anterior pairs, light red-ferruginous; a pair of large spines at the apical ends of posterior tibiæ. Abdomen smooth and shining; at the apical ends of the 1st and 2nd segments a broad yellow fascia trifid basally, the extreme apical margins dark-coloured; the 2nd segment has also a lateral linear yellow spot; each of the four following segments has a longitudinal oblong yellow spot in the middle above, and also an elongate yellow one laterally, the lateral ones in the 3rd, 4th, and 5th, occupying nearly the whole length of the segment; the 6th has three yellow lateral spots; and the two following segments have yellow stripes extending to the apical segment, of which the margin is dark-coloured; the minute anal styles at top flavescent; the end of abdomen very thick, largely revolute, and there 5 lines in diameter. Ovipositor setaceous, stiff, slightly curved, 2½ inches long, its two sheaths ciliate and finely serrulate at margins, and coiled up (in spirits); tips sublinear-spathulate, concave, obtuse, membranous, light-coloured.

Length, direct and plane, 18 lines; or, to extreme end of curvature, 22 lines.

Hab. High and dense forests near Norsewood, Waipawa County; April, 1884: W.C.

Obs. This fine insect is entirely new to me; and from its being so large and so striking I conclude it to be scarce. None of the many residents in that locality had ever seen one before, and were much struck with its size and handsome appearance. For a long time I have been in doubt whether it is not Rh. fractinervis, Vollenhoven; which species, in spots and markings, it greatly resembles, and it is only after long and close study of it, and comparing it with the description given of Rh. fractinervis966 that I have believed it to be distinct. Its much larger size, very peculiarly shaped end of abdomen and lateral yellow spots on its second segment, dark colour of its femora and posterior tibiæ, etc., striped clypeus, yellow margins of the basal joints of antennæ, iridiscent and hairy and dusky-coloured wings, 3 ocelli, etc., have caused me so to determine.

Genus Lissonota

L. multicolor,967 sp. nov.

Ferruginous, spotted with yellow and black. Head: orbits of eyes, genæ, a narrow transverse line above labrum, and mentum light yellow; [160] a black spot on vertex, a black ring round occiput and neck; antennæ length of body, black; maxillæ and maxillary appendages fulvous. The prothorax yellow anterior edge; mesothorax, a broad black longitudinal line on mesonotum anterior end, with a yellow narrow and longer line on each side, a black lateral line from junction of anterior wing to the yellow line of the prothorax, with narrow black curved lines at lateral edges, small black spots above the junction of wings, and a small dark triangular spot at posterior edge of mesonotum, two small yellow spots beneath the junction of the wings and two larger yellow spots running diagonally towards intermediate coxæ; metathorax, a large triangular black spot on anterior edge of metanotum, with a small yellow transverse bar at its base (post-scutellum), and a large yellow lateral line diagonal towards posterior coxæ, scutellum mottled with yellow, slightly and sparsely acicular at apical end; sternum black; wings iridiscent finely hairy and ciliated, hairs black springing from minute tubercles; stigma and nervures brownish; areolet small, subquadrate. Legs ferruginous; coxæ yellow above; tarsi joints barbed and slightly hairy, the last joints of tarsi and ungues dark brown: posterior pair, coxæ black below with a ferruginous line; trochanters black; femora with a fusco-testaceous longitudinal line above: anterior pair, trochanters with a brown line; spurs long on the two posterior pairs. Abdomen ferruginous above, yellow below, a line of fuscous spots at lateral margins of the 3rd on to the 6th segments, a narrow darkish line on the lateral edges of the first three segments, and a light ferruginous one below it on the first four segments; extremity yellow, with a minute black style on each side; ovipositor 4 lines long, light ferruginous at apex, sheaths darker, ciliate. Length of body, 4½ lines.

Class I. Dicotyledons.

Order I.968 Ranunculaceæ

Genus 3. Ranunculus, Linn.

1. Ranunculus amphitricha,969 sp. nov.

A Low perennial, perfectly glabrous, slender, creeping herb, stolons very long, rooting at nodes, rootlets very long. Leaves rather distant, generally two from a node, erect, orbicular-cordate in outline, 7–9 lines diameter, ternisect, the two lateral lobes bisected nearly to base, each lateral lobe having 3–4 laciniations, middle lobe always cuneate and trifid, with a minute laciniation or notch on each side, and mostly very regular; petioles slender, fistular, 2–2½ inches long, winged and clasping at base. Scapes or peduncles rather stout, 1–2 inches long, springing from node on the opposite side to the leaves, 1–3-flowered; flowers single, on long pedicels, 3 lines diameter; sepals 5, shorter than petals, orbicular, greatly concave, inflated, erect, obtuse, sub-papillose, one sepal always deeply emarginate or sub-bifid; petals 5–6, spreading, narrow, linear-oblong, obtuse, 2 lines long, yellow, shining, simple veined; vein forked at apex; unguiculate, ungues nearly as long as the lamina, the gland at base of lamina large, extending nearly across, erect, thickened, slightly toothed at top; stamens numerous, filaments long, anthers round bright yellow; styles erect when young, long recurved and subulate when mature; stigmas pubescent; achenes turgid and subpapillose when young, sub-globular and rugosely-papillate when mature, 12–15 collected in a globose head as large as a small pea; receptacle (ripe) largely echinately chaffy or squarrosely-hairy at base; hairs flat, translucent, bordered.

Hab. In muddy watercourses, edges of woods near Norsewood, County of Waipawa; 1880–84: W.C.

Obs. I have long known this plant, it has given me no small amount of yearly consideration and labour. I had long supposed it to be a variety of R. rivularis and of some allied Australian species; but on closer examination in its living state, and noting its differential (? specific) characters (supra), which are permanent, I cannot but conclude it to be distinct.
