[Read before the Auckland Institute, 17th October, 1892.]

Fam. Drassidæ.

Gen. Drassus, Walck.

Drassus scitulus, sp. nov.

Fem.—Ceph.-th., long, 3.6; wide, 2.5. Abd., long, 3.1; wide, 2. Legs, 4, 1, 2, 3 = 10.3, 8.5, 7.9, 7.3 mm.

Cephalothorax ochraceous or tan-colour; dorsal aspect mostly covered by a large, brownish, leaf-like mark, whose serrated margins have a somewhat deeper shade; petiole extends from middle of caput to hind-central eyes; the broad lateral bands on cephalic part are confluent with the leaf-like figure; marginal band narrow, fuscous; thoracic groove reddish. Very sparingly clothed with fine light hairs. Oval, moderately compressed forwards; pars cephalica subquadrate, somewhat depressedly convex above; clypeus less than one-third depth of facial space; thoracic part slopes somewhat abruptly; groove well defined; caput and radial striæ fairly well marked; contour of profile ascends from stalk at an angle of 60°; caput curved, second half shows a more abrupt incline.

Eyes do not differ much in size; posterior row form a slightly procurved line; median pair on dark, oval spots, separated from each other by an eye's diameter; about that interval and a half from laterals; anterior row recurved, arch about as pronounced as hind-row, length exceeds space occupied by three eyes of posterior line, centrals posited on a slight elevation, smallest of eight, placed rather nearer to side-eyes than they are to one another—a space visibly shorter than their own breadth; laterals posited on low tubercles, divided by an interval fully equalling their own diameter.

Falces brownish-ochreous; sparingly haired; project well beyond plane of clypeus, stout, breadth equal to more than one-half length.

Maxillœ colour of falces; gradually dilated, round-pointed.

Labium deeper shade; oval, half length of maxillæ.

Sternum and legs concolorous, clouded round margins; broad-ovate.

Legs yellow-ochreous; femoral joints have four, patellar one, tibial and metatarsal two broken, deep olive-green annulations; sparingly furnished with fine hairs; spine armature—

– 166 –

first and second pairs, femora 2 or 3; tibiæ 2, 2, 2, 2; metatarsi 2, 2, 2; femoral joints of hind-pairs 3 or 4; tibial 2, 2, 2, two spines on outer and inner sides; 1, 1 on superior aspect; metatarsal joints about 18 spines; tarsal claws 6 teeth; scopula moderately developed.

Palpi and legs concolorous, rings evanescent.

Abdomen inversely-ovate; hairs yellowish, short, thinly interspersed; brownish-ochreous, specific pattern fuscous, somewhat intricate; basal fourth occupied by two parallel conduplicate figures whose inner ends are prolonged and deviate beyond the reddish impressed spots, terminate at a wide lanceolate mark, with somewhat tooth-like dilatations, enclosed within this figure are four acute chevrons, increasing in size, of the normal ground-colour; lateral margins exhibit a series of oval spots; ventral region sparingly spotted; spinners orange-ochreous. Corpus vulvœ represents a moderate elevation, occupied by two subcircular foveæ, divided by a wide septum nearly their equal in breadth.

The four examples that I have—three females and an immature male, which closely resembles them both in form and coloration—of this handsome little Drassus were captured by Captain T. Broun at the Hunua, near Auckland.
