a broad full face with spreading horns); pronotum thickish; shield-like, margined, both it and mesothorax very dark; abdomen slightly compressed, clouded; abdominal segments darker below, increasing in hue towards tip; oviduct large, very thick at base; 10 lines long, curved, brown almost piceous. Legs stout; femora with 2 (sub 3) rows of black coarse oblong spots on each side; hind femora with a row of large black spines on lower margin (which is also black), and 2 minute ones inside of the row; the 4 anterior femora smooth; 4 anterior tibiæ with 5 black spines on each side; hind tibiæ very stout, black, with 4 long black spines on the outer side and 5 on the inner side, the third and fourth of the inner ones very long (⅛in.) and sharp, and 2 small spines distant on the upper ridge; the posterior femora and tibiæ of about equal length—11 lines long; the anterior tibiæ with a pair of spines at the lower joint, upper side; the middle tibiæ with a single spine there; the posterior tibiæ with 2 pairs of spines ditto; tarsi piceous, almost black, slightly hairy; hairs short, patent; pulvilli thick, tumid, blackish, shining.

Hab. Found in firewood obtained from Forty-mile Bush, County of Waipawa, 1888; per Mr. A. Hamilton.

Obs. A peculiar species, differing from other described ones in its general very dark colour, extreme glossiness, having also a sub-metallic cupreous glow in several places, peculiar broad and coarse femoral markings, extra spines, remarkably thick and smooth tumid pulvilli, and hairy antennæ. I regret much the upper portions of the antennæ being wanting.
