Coleoptera.

Fam. Curculionidæ. Genus Scolopterus.


Scolopterus submetallicus,768 n. sp.

General colour black-green, very glossy, femora purple-black, legs piceous; elytra punctured coarsely in lines on back, faintly on sides; head smooth; shoulder-spines straight, acute; posterior femora large, armed with a large acute tooth near base; pulvilli bordered with white. Length 4¼ lines.



Hab.—Forests near head of Manawatu river, 1880.

This specimen flew down from a high tree, and alighted on the sleeve of my coat. As a species it ranks near to S. tetracanthus.


Genus Rhyncodes.


Rhyncodes weberi,769 n. sp.

Insect villous; general colour reddish-brown intermixed with grey, and mottled with small greyish-white blotches on elytra; pronotum brown, finely punctulate; elytra, five black shining longitudinal lines slightly and closely tuberculated in small raised dots, parallel with five black smooth lines, outer edge stout, black, glossy, strongly and regularly marked with small transverse riblets running inwards at right-angles; abdomen beneath black glossy, with a few short scattered hairs, and three broad longitudinal rows of mottled hairs; femora, and sides (shoulders) of pronotum, black, glossy, and slightly punctulate; a small tuft of reddish hairs at bases of femora; coxæ densely villous; tibiæ and tarsi very hairy; pulvilli very large, broadly orbicular-obcordate; antennæ stout, serrated, hairy throughout and coarsely ciliated, nearly as long as the rostrum; head and rostrum very hairy, with red-brown hairs. Length, including rostrum, 15 lines. [282]

Hab.—Hawke’s Bay; C.H. Weber, Esq., 1878.

A species near to R. ursus, but much larger.



Rhyncodes rubipunctatus,770 n. sp.

Insect wholly covered with very short whitish-grey down, finely and thickly speckled with light-red, which (below especially) assumes a flattish semi-scaly appearance, each minute speck of reddish down or hair showing a regular circumscribed shape; pronotum dotted profusely and finely with black raised irregular dots, and bearing two semi-lunate and two smaller brown spots; elytra extending sharply over abdomen, with 12–14 longitudinal sub-striated rows of black raised shining dots, mottled with 2–8 small brownish markings in a line with those on pronotum; abdomen below with three fine transverse black lines near anus; head between eyes and base of rostrum coarsely dotted with raised brown dots; eyes large; rostrum jet-black, smooth; antennæ as long as rostrum and slightly hairy. Length, including rostrum, 9 lines.

Hab.—Hawke’s Bay, Patangata; captured by Mr. G.W. Tiffen, 1880.

Another specimen, taken in the same neighbourhood by Mr. Winkelmann, bit its captor’s hand pretty sharply through his handkerchief, causing it to bleed.

[Read before the Hawke’s Bay Philosophical Institute, 14th November, 1881.]

Class I. Dicotyledons.

Order 1. Ranunculaceæ.

Genus 1. Clematis, Linn.

Clematis quadribracteolata,771 n.sp.

Plant diœcious, small, very slender, trailing, extending only a few feet each way; branches sulcated, glabrous or with the young ones slightly and finely puberulent; leaves few, very minute, trifoliolate, on long petiolules 2–3 lines long, mostly ovate-acuminate and broadly lanceolate, or spathulate, ½–1½ lines long, and sometimes linear-lanceolate 3–5 lines long acute with a knobbed point, no lateral veins, only a mid-rib, with here and there a [330] trifid leaflet, glabrous on both sides, sub-coriaceous, entire, dark-green margined with a deep black line; petioles glabrous, opposite, 1–2 inches long; flowers opposite, axillary solitary, sometimes (though rarely) two from one axil, and very rarely three pedicelled on one peduncle; peduncle ½–1½ inches long, shorter than petioles, tri- and quadri-bracteolate, slightly pubescent below, densely so from uppermost pair of bracteoles; bracteoles free, connate, cup-shaped, pubescent, very obtuse and rotund at apices, obsoletely veined, each pair increasing in size upwards, the largest pair nearest the flower; sepals four, dull light-purple, thin, slightly spreading and revolute, 3 rarely 4 lines long, ovate, oblong-lanceolate, obtuse, glabrous within, silky pubescent without, ciliated, finely and obscurely veined longitudinally with 4–5 veins; male flowers on peduncles usually shorter than those bearing the hermaphrodite ones, and with only three pairs of bracteoles; anthers 25–28, elliptic, obtuse, light yellow; filaments broadly linear-lanceolate, flat, dark purple, outer shorter than sepals, inner sub-sessile; hermaphrodite flowers with only four stamens; pistils white, silky, very glossy at first, a little longer than sepals, glabrous, curved and clubbed at points; achenes 22–24, capitate, sessile, ovate, subsetose with short white hairs; tails very hairy, 8–9 lines long.

Hab.—In low-lying marshy spots, Hawke’s Bay, S.W. and S. side.

This little plant has long been imperfectly known, no doubt partly owing to its small size (when compared with its indigenous congeners), to its want of striking colours, to its lowly growth, and to its peculiar habitat—hidden among the rank vegetation of marshes and on the edges of watery places, and not unfrequently springing from within a large tuft of Carex virgata. I first met with it so long back as 1847, on the banks of the Lake Rotoatara, near Te Aute, but my specimens then were incomplete. Subsequently (1872) it was detected by Mr. Sturm in the low ground between the Ngaruroro and Tukituki rivers, near Clive. Mr. Sturm also removed plants to his nurseries in hopes of cultivating them, but failed. Last year (1880) it was also found by Mr. Hamilton, in similar localities, near Petane; from him I have received ample specimens, in various states, which have enabled me to draw up this description. Though small, it is a neat-looking, almost a graceful plant, and differs widely from all our indigenous species of Clematis, as well as from the described Australian, Tasmanian, and South Pacific species. This species has but very slight affinity with C. fœtida, Raoul, under which species Dr. Sir Jos. Hooker had provisionally placed it as a variety.772



Clematis parkinsoniana,773 W.C.

Hermaphrodite, or Female, Plant: Leaves trifoliolate, smaller and much more regular in size and outline than in the male plant, each leaflet usually ovate, 4–10 lines long, and deeply incised with 2–6 incisions, [331] mucronate, not unfrequently a leaflet is again subdivided into three leaflets, when each lesser leaflet is also petiolulate, and then is pinnate below; veins as in male plant; hairs the same, but the whole plant is still more thickly covered with them, golden and glossy; common petiole 1–1½ inches long, slender, filiform; petiolules 4–12 lines long flowers numerous, diameter 9–12 lines, disposed in opposite axillary free panicles, 2½–3 inches long, bibracteolate at or near base; sepals six, as in male flower, longer than pistils; anthers (infertile) 8–9, narrow, linear; filaments somewhat lanceolate, broad, flat, one-nerved, shorter than pistils, about half the length of the sepals; pistils, at first silky, shorter than the sepals; pedicels opposite, 5–7 lines long, single-flowered, bracteolate at base, lowermost ones also bracteolate about the middle and 8–10 lines long; bracts and bracteoles connate, etc., as in male plant: achenes, 22–26, capitate, sessile, broadly oblong-lanceolate, sub-hispid with short patent hairs; tails very hairy, 12–14 lines long, flexuose, with curved and thickened tips.

Hab.—In forests, banks of streamlets, head of River Manawatu, 1881, (same localities as male plant), flowering in October, fruiting in December.

This, the female plant, bears a generally neater and more graceful appearance than the male plant, owing to its smaller, more regular, and more silky foliage; like the male plant it forms thick, dense, impassable bushes, often enveloping other plants and shrubs. I noticed, also (this year), that the flowers of the male plant were not so fugacious as I had formerly found and described them; which, at that time (in 1879), was no doubt owing to my first finding them later in the season (November) and just after very heavy rains.

For a full description of the male plant, see “Trans. N.Z. Inst.,” vol. xii., p. 359.
