This species is' smaller than any of the foregoing. The following description and measurements, are taken from a pair
of co-types presented to the Canterbury Museum by Mr. H. Suter, the discoverer of the species:—
Fastigium broad, the fovea shallow. The lateral margins of the lobes of the pronotum are oblique, ascending posteriorly. The fore and middle femora have no apical spines, and none below; the hind femur of the male has an apical spine, but it is situated below, not laterally. It is absent in the female. Below there are, in both sexes, from two to four small spines. Both fore and middle tibiæ have a pair of inferior apical spines, but only one of the superior pair, which is on the inner side; below they have four spines in each row, and the middle tibia has a single spine in front, beyond the middle. The hind tibiæ, above, have four spines in the outer and five in the inner row; below there are three spines in the outer and two in the inner row. The fourth joint of the hind tarsus is short, not longer than the first. Supra-anal plate obtusely notched; the subgenital plate in the male deeply concave between the insertions of the styles; in the male it is large and slightly notched at the apex. The ovipositor is more compressed than usual.
Colours.—Dark; the pronotum bordered all round, and the abdominal terga bordered posteriorly, with testaceous or tawny. (In alcohol.)
Length, 25mm.; of head, 13mm. ♂, 10mm. ♀; of pronotum, 5mm.; of thorax, 9mm.; of abdomen, 15mm.; of oviduct, 13mm.; of fore tibia, 7mm.; of hind tibia, 12mm.; of hind femur, 11mm. Width of head, 7mm.; of pronotum, 8mm.
Localities. — Hooker Valley, South Canterbury; Mount Captain, Hanmer Plains, at about 3,000ft. above the sea. (Dendy.)
In the absence of apical spines on the femora, this species differs much from all the others.
The following are the colours of a live specimen collected by Professor Dendy on Mount Captain: Head shining-black, ante-clypeus white, with two brown spots. antennæ reddish-brown, paler towards their tips. Legs pale reddish-brown, the spots on the outer surface of the hind femora and the spines on the hind tibiæ black. Pronotum shining-black, margined all round with dirty-white, clouded with fuscous. Abdominal segments, above, shining — black anteriorly; posteriorly white, with dead-black spots and vermiculations. The length of this specimen, which is a male, is 38mm.
