The first joint of antennæ about twice longer than the second and shorter than the third; the second more than twice longer than wide, about half the length of the third, which is shorter than the fourth. Lower part of front, face and clypeus covered with silvery pubescence. Apex of clypeus with a shallow, rounded incision.

Collar long, as long as the space between the front ocellus and the end of the vertex. Middle lobe of mesonotum covered closely with round punctures, which are large and deeper at the apex; the lateral lobes sparsely punctured, more thickly at the base.

Antennæ black, the scape rufous in the middle below, the flagellum densely covered with a short, stiff pile. The second joint of antennæ not much longer than broad, the third about twice its length and slightly shorter than the fourth. Apex of clypeus with a wide, shallow, rounded incision. Hind ocelli separated from each other by double the distance they are from the eyes; they are flat, closely rugose, except round the hinder and inner edges. Temples roundly narrowed, as long as the eyes. Occiput roundly incised. Collar short, above as long as the third antennal joint. Middle lobe of mesonotum strongly, but not very closely punctured; lateral lobes almost impunctate; a fine furrow down the centre; the outer edge with an irregularly crenulated furrow. Scutellum flat, more strongly and deeply punctured than the mesonotum. Mesonotum punctured round the furrows. Metanotum strongly, transversely reticulated, with a stout keel down the centre. Pro- and base of mesopleuræ strongly aciculated; the rest irregularly reticulated; apex of propleuræ depressed, irregularly crenulated. Hind coxæ nearly four times longer than wide, closely, strongly striated except at the base, which is closely punctured. Hind metatarsus shorter than the other joints united.

This species is closely related to G. dunbrodyense, Cam.; possibly it may be its; the occiput is more distinctly incised; viewed from above the collar is shorter; the red on the mesopleuræ is of equal width, not broadly dilated towards the base above as it is in the of dunbrodyense. The males appear to be rare compared with the females. The only other male I have seen is G. lissocephalus, Cam.

* G. lissocephalus, Cam., has the thorax entirely black, as in G. pulchripenne, with which it appears to be closely allied; the abdomen is black except for broad rufous marks on the apices of the second, third, and fourth segments, the base of the third and fourth being also narrowly red; the four anterior femora, tibiæ, and tarsi are testaceous; the hind legs are for the greater part black. The head is broader than long; the temples are as long as the eyes, slightly narrowed; distinctly so at the hinder edge; the occiput is distinctly roundly incised. The hinder ocelli are placed slightly behind the eyes; they are separated from each other by about the same distance as they are from the eyes. Malar space as long as the pedicle of the antennæ. Antennal scape about three times, the pedicle about twice

longer than wide; the third joint is shorter than the fourth. Collar, as seen from above, broader than long. Mesonotum strongly rugosely punctured; the sides of the lateral lobes closely finely aciculated-punctured, with a row of large punctures down the middle. Scutellum finely, aciculated punctured. Metanotum with a stout keel down the centre; this keel is bordered by short, clearly separated transverse keels on both sides; the rest is irregularly rugose, more or less longitudinally striated, especially above, and thickly covered with white pubescence. Mandibles rufous, the teeth black. Hind coxæ three times longer than wide, finely transversely striated; the hind legs black; the basal half of the femora and base of metatarsus rufous. Wings hyaline, the stigma testaceous; the posterior discoidal cellule is not much shorter than the upper; the nervures are received at the same distance from the base and apex. I have G. lissocephalus from Cape Colony.

Cape Colony. Neighbourhood of Cape Town.

This species resembles closely G. dunbrodyense, Cam. (Records of the Albany Museum, i. 159), but may be separated by the radial cellule being shorter and wider, by the posterior discoidal cellule being of equal width, whereas in dunbrodyense it is distinctly narrowed posteriorly, the head is broader and shorter, the hind ocelli are not so widely separated from each other as regards their separation from the eyes, the first abdominal segment is longer and thinner and the four anterior legs are not whitish yellow in front.

Reddish brown; the front, vertex broadly in the middle, the lower part of the hind orbits, the greater part of the middle lobe of mesonotum, metanotum, a large triangular mark on the propleuræ, basal half of mesosternum, the top and base of metapleuræ, and the fourth and following segments of abdomen, black. Antennæ dark-red, the second, third, and base of fourth joints black. Legs coloured like the body; there is a yellowish-white band on the inner side, near the base of the hind tibiæ. Wings hyaline, iridescent, the stigma dark testaceous, the nervures darker coloured. f.

Length 16 mm.; terebra 13 mm.

Head smooth; the apex of the clypeus with a semicircular depression and with a shorter, wider depression on either side. Apex of mandibles black. Head thickly covered with silvery pubescence. Malar space as long as the second antennal joint. First atennnal

joint not quite twice the length of the second, which is slightly longer than broad; the third is as long as the basal two united and shorter than the fourth. Hind ocelli separated from each other by less than double the distance they are from the eyes; the hinder are placed in front of the hind edge of the eyes, not beyond them as in G. dunbrodyense. Malar space less than the length of the second antennal joint. Base of middle lobe of mesonotum rugose, the middle with clearly separated punctures, the apex more sparsely punctured. Scutellum with some large punctures. Metanotum aciculated, with scattered punctures, the middle bounded by curved furrows; the sides thickly covered with white pubescence. Propleuræ strongly aciculated. Mesopleura irregularly reticulated, with a large, triangular, strongly aciculated space at the base, the wide lower end of which is bounded by a furrow.. Metapleuræ more regularly reticulated. Apical slope of metanotum irregularly transversely striated, with a smooth line down the middle. Hind coxæ four times longer than wide; the upper side strongly striated, more strongly in the centre than at the base or apex. Anterior discoidal cellule small, narrow, slightly narrowed towards the apex; the apical cellule of the same width. Pronotum short, as long as wide, as seen from above. Hind metatarsus shorter than the other joints united. Apex of sheath of ovipositor cream-coloured.

ALYSIIDÆ.

ALITHA, gen. nov.

First abscissa of radius very short, but distinct, issuing from the centre of the stigma, which is linear, moderately broad. First abscissa of cubitus received shortly below the first transverse cubital nervure, united to the top of the recurrent nervure. Transverse median nervure received distinctly beyond the transverse basal. Radial cellule long, wide, reaching to the apex of the wing; the radius and cubitus in the hind wing short, indicated only on the basal half; at the base in front there is one large closed cellule, bounded anteriorly by a stout nervure (the præbrachial ?); at its base behind is a short cellule. Parapsidal furrows distinct. The middle of the base of metanotum bears a longitudinal keel, which curves round to the sides, forming two large smooth area, bordering the top of the apical slope, which bears some longitudinal keels. Abdomen smooth, the ovipositor slightly longer than it.
