Deinacrida armiger,963 sp. nov.
Male: Whole insect smooth and shining and variously coloured.
Head large, oblique, broadly ovate, 1 inch long, rather wider than prothorax, bright dark red-brown, vertex much convex; eyes prominent sub-pyriform; antennæ setaceous, 3¾ inches long, light brown, finely and densely pubescent; a lighter-coloured ridge between eyes and antennæ with a linear oval centre; clypeus black with a narrow white lower margin bearing two dark longitudinal streaks; genæ rugose, protuberant, black; labrum large, emarginate, brown; palpi light tawny, largely clavate, tips sub-globular, whitish, pubescent; mandibles large, black and toothed, sub-rugulose, the left mandible larger and overlapping. Thorax: pro-thorax 4 lines wide, concave, sub-rugulose, whitish with a slightly reddish tinge, and blackish markings resembling a shield and its two supporters, and with narrow black anterior and posterior margins, side-margins slightly reflexed; mesothorax 2 lines wide, reddish-brown, with two minute black markings and a black dot on each side; metathorax 1 line wide, of a similar colour and two black dots; sternum of thorax, coxæ, and femora below, light fulvous-red. Abdomen thick, convex, compressed, 13 lines long, much arched at second and third segments, light reddish-brown, irrorated, with blackish bands on lower margins, of segments, and a reddish-pink hue on the lighter-coloured parts; anal appendages greyish, pubescent, Legs:  posterior pair very stout and long, femur and tibia each about 10 lines; anterior pairs much smaller; anterior and intermediate coxæ armed with a large light-fulvous spine; the upper surface of all femora whitish with a reddish tinge, smooth, each having three longitudinal lines of short dark-brown diagonal streaks on the outer, and two lines on the inner side, but on the posterior pair those two inner rows possess short muricated points, this latter pair is also sulcated on the lower side and black at the lower end, and bears five spines on the outer and six smaller ones on the inner edge, each row gradually increasing in size downwards; posterior tibiæ very stout, dark brown, triangular, four large spines on the outer and five on the inner edge, and five spines together at the lower ends; anterior and intermediate tibiæ 7 lines long, brown, each having five pairs of spines on the lower edge, and two spines on the upper edge at the lower end; a sunken oval depression 1½ lines long, covered with a bluish-grey spotted and thin membrane, on both sides of anterior tibiæ near the upper end: tarsi, brown, hairy; ungues and tibiæ slightly so; pulvilli (or four cushions on sole) remarkably large, hemispherical, glabrous, bluish-grey.
Hab. Wairoa, Hawke’s Bay, whence received in spirits; 1884: W.C.
Obs. This is both a peculiar and pretty species, something dapper and taking about it, from its many and bright contrast colours; the dark markings on the light ground of the prothorax are symmetrical and curious, and closely resemble a 6-angled shield with its two supporters! Hence its trivial name. It seems allied to D. (or Hemideina) megacephala, Buller; and possesses characters belonging to those two genera,—if they are really and naturally distinct, which I doubt.
Myrmeleon novæ-zealandiæ,964 sp. nov.
Body slender, densely pubescent, black above and below, sub-iridiscent, with yellowish joints to abdomen, and a broad grey lateral stripe running down each side that is less hairy; extremity of abdomen brown with whitish spots, and a tuft of longish black rigid hairs; abdomen much shorter than wings. Head, vertex and thorax glabrous, with a few longish soft hairs on prosternum and at junctions; piceous-brown above, yellowish and spotted with brown below and at base of antennæ; clypeus large and labrum yellow, with 4–5 dark hairs on the latter; mandibles large piceous; palpi light brown, dark at tips; eyes very large and prominent, metallic-greenish, shining, with, innumerable facets; antennæ 3 lines long, diverging, curved, bluish-black, the two basal joints whitish spotted with brown, clavate with a mucro, annulate, about 30–32 rings, with very fine short verticillate hairs;  prothorax small; mesothorax curved upwards and projecting shell-like over prothorax, with a loose space between neck and pronotum, and a larger one between prothorax and mesothorax. Legs hairy, piceous-black, with two large spines (spurs) at lower end of tibiæ; femora yellow above, brown at lower end; ungues long, diverging and bright red-brown. Wings iridiscent, brownish, finely ciliate with dark hairs, densely reticulated, cells all shapes and sizes, but more regularly rectangular on sub-median vein, and largest between sub-costal and median veins, pilose with long dark and rather distant hairs on all veins and bands; spotted generally with brownish dots and markings, that are somewhat sub-quadrate at bands and triangular at forks (and sometimes broadly so at bands), outer edges irregular and not defined, the centre of the wings free of spots, also the costal cells from base to stigma: anterior wings (each) 1½ inches long, 5 lines wide, sub-oblong-lanceolate, dimidiate, much contracted at base, obtuse-pointed at tip, apex inclined below; stigma oblong, whitish-yellow (or light cream-colour) with short dark hairs, a large black-brown spot at the basal end, and a brown blotch opposite between sub-costal and median veins, and another blotch directly opposite towards lower margin; costal vein yellow at base and gradually becoming brown; sub-costal vein double for about two-thirds of length of wing—from ¼ inch from base on to stigma, and without bands between,—yellow with brown dashes at junction of bands, and on sub-median vein below; ante-cubitals straight, simple; post-cubitals forked and sloping, a few in the centre forming cells: posterior wings each 1¼ inches long, 4 lines wide, sub-linear-oblong, more acute, and less and more finely spotted than anterior pair; spots mostly triangular in forks below stigma and about tips; stigma rather large, oblong, whitish; a brown blotch opposite stigma and near the lower margin.
Length of the body 16 lines; of the wings extended 38 lines.
Hab. Seventy-mile Bush, Waipawa County; (rare, like other species of the genus; three specimens only obtained with much difficulty); 1882–83; W.C.
Obs. A very elegant insect, in form, colour, iridiscence, and finely hairy and ciliated wings; in this latter respect closely approaching the next sub-order Trichoptera. It seems to have some affinity with our only other and little-known New Zealand species of this very large and cosmopolitan genus,—M. acutus, Walker, (B.M.),—judging from description only; but it is very distinct.
The larva is ovate, thick, fleshy, largely convex above, 6–7 lines long, 3 lines broad, of a reddish-grey hue, spotted with brown and black. Head 1 line long; mandibles 1½ lines long, curved, hairy, grooved on lower surface, each having three large and stout curved spines on the inner margin;  antennæ very small and slender at base of mandibles. Two large brown spots sub-lateral on metanotum; two smaller ones similarly situated on mesa- and pronotum. Abdomen of a lighter colour below, with eight transverse and equal corrugations above, each having five black hairy spots running in regular lines longitudinally. Legs (and mandibles) yellowish-brown, very hairy with spreading black hairs; ungues of posterior pair large, divergent, piceous. Hairs of two kinds: (1) whitish, downy, and appressed; (2) black and bristly, and often in tufts, which are larger at the sides, the largest pair of tufts are marginal just opposite to the posterior legs.
Hab. Hampden, Waipawa County; 1882: Mr. S.W. Hardy.
Obs. This species makes its pitfalls in sandy earth, just like the European species M. formicarum. I kept several of these larvæ alive for some time (2–3 months) in light dry soil, they seemed to bear fasting very well. This is a much larger larva than that of M. acutus (?), which, I think, I knew, and often watched its habits, at the North, in forming pitfalls, etc., in sandy spots; though I never met with the perfect insect of that species.
