hyaline, spotted: Antennæ ringed with white, not greatly dilated at the apex. The offers no essential differences.

This genus should be known by the total absence of the parapsidal furrows. The abdominal petiole is long and slender and is not much dilated at the apex; it is as long as the following two segments united. The radial cellule is long and narrow, reaching to the apex of the wings. On the centre of the apex of the clypeus, in the ♂, is a small tubercle. There is no metapleural keel along the lower edge; but there is an oblique plate-like one bordering the apex of the middle coxæ. The hind legs are greatly lengthened. The ovipositor in the known species is short. Temples wide, oblique. The sides of the median segment at the apex are broadly rounded. There is a triangular fovea on either side of the base of the postscutellum. The last joint of the hind tarsi as long as the third. There are no transverse keels on the metanotum. In the most recent arrangement of the Mesostenini, namely that of Dr. Schmiedeknecht, Opus. Ichneum., 560, this genus would come nearest to Crypturopsis, as it does also, through the shortness of the thorax, in that of Ashmead, Bull. U.S. Nat. Mus., xxiii., 44. Crypturopsis is an American genus.

CRYPTAULAX RUFICEPS, sp. nov.

Black; the head red, the apex of the fifth, the sixth to ninth, and the base of the tenth antennal joint, clear white; the antennal scape red. Wings hyaline, iridescent, there is a large cloud extending from the commencement of the transverse basal nervure to the commencement of the radius, where it is roundly narrowed; there is a cloud of similar size at the apex, commencing at the base of the apical third of the radius; both are distinctly violaceous in tint. and .

Length 14 mm. ; terebra 3 mm.

Natal. Malvern.

Face closely, but not strongly punctured; the top of the clypeus punctured; the centre flat, furrowed below, the furrow leading into the projecting apical tooth. Front and vertex smooth; the former keeled down the centre; the part above the hollow and below the ocelli is obliquely striated. Inner orbits distinctly margined above. Mesonotum closely, somewhat strongly punctured-reticulated, towards the apex in the centre striated. The scutellum shining, somewhat strongly, but not closely punctured. Median segment closely, strongly reticulated. Pro- and mesopleuræ closely, strongly longitudinally striated; the latter more closely below than above.

Abdomen smooth, shining; the apex of the apical segment is narrowly white.

The apex of the fore femora and the tibiæ are testaceous in front. The has the wings fuscous violaceous except for a hyaline cloud extending from the commencement of the radius to the base of its apical third; the antenna want the white ring; the sides of the face have the red colour tinged with yellow, the red on the base of the mandibles being also tinged with yellow; in it also the apex of the petiole has a violaceous tinge and the abdomen is more densely pilose; the second segment is narrow at the base; it becomes gradually wider towards the apex. The apex of the clypeus is more transverse than it is in the ?. The palpi in both sexes are black; the mandibles broadly rufous at the base.

The I have described may belong to another species, as, e.g., the fore wings are not hyaline at the base and the hinder pair are entirely smoky. The material at my command does not warrant me in describing the as a distinct species. Cryptus pictipennis, Tosq., from Caffraria (only the is known), is clearly another species of Cryptaulax. No mention is made of a tubercle or small. tooth or projection on the apex of the clypeus, which is described as having the "margine anteriore rotundata"; and the posterior lobes of the "prothorax" are said to be transversely striated; and the pleuræ "are more finely punctured" than the mesonotum; in the ♂ I have described they are not punctured, but coarsely reticulated, although not quite so strongly as in the . The transverse median nervure, however, is said to be interstitial; but the mesonotum is said to be "sans aucune division," and the transverse median nervure is broken above the middle. As the areolet is described as "small" it can hardly be a true Cryptus. It is further to be noted that the abdomen is said to be "smooth," which is certainly not the case with either the or? I have described.

CRYPTAULAX ERYTHROSTOMUs, sp. nov.

Black, the clypeus and mandibles, except at the apex, red; wings hyaline; a cloud commencing on the inner side of the transverse basal and transverse median nervures, extending to the base of the stigma and the middle of the disco-cubital nervure, the cloud being therefore much narrowed in front, and the apex from shortly behind the base of the apical third of the radius, fuscous violaceous; the hind wings are entirely hyaline; the nervures and stigma black. 3. Length 12-13 mm.

Metanotum closely, strongly reticulated-punctured; the pleuræ strongly, obliquely striated reticulated. The upper part of the propleuræ is punctured, the middle smooth, the lower strongly striated. The upper basal half of the mesopleuræ is irregularly striated, the apical smooth, the lower part is strongly punctured, more or less striated. Abdominal petiole long and slender, fully longer than the following two segments united; the post-petiole is hardly dilated; the spiracles are prominent; the second segment has the basal third narrowed.

LARPELITES, Cam.

LARPELITES RUFICOLLIS, Cam.

Records Alb. Mus., i., 145.

This species is in the collection from Estcourt, Natal (E. Haviland). Cryptus celer, Tosq., from Senegal (Mem. Soc. Ent. Belg., v., 161), is clearly another species of the genus. It is to be noted of L. ruficollis that the propleural keel curls round inwardly at the top.

STENOMERIS, gen. nov.

Wings uniformly fuscous violaceous; the areolet small, square; disco-cubital nervure not broken; transverse median nervure interstitial; the transverse median nervure in hind wings broken shortly below the middle. Median segment closely, rugosely punctured, without keels; the spiracles long. Abdominal petiole slender, long, not distinctly dilated at the apex; the post-petiole not separated. Temples wide, roundly, obliquely narrowed. Clypeus roundly convex, clearly separated by a deep depression from the face; its apex dilated in the middle, separated from the side, but not projecting downwards. Labrum hidden. Mandibles with two large teeth. Parapsidal furrows indistinct, narrow, shallow. Scutellum not raised above the level of the mesonotum; its basal depression large, deep.

It is doubtful if this genus should be placed in the Cryptini or Mesostenini; the form of the areolet does not give always a trustworthy distinction between the two. In the present species the areolet, although small, is closed at the apex; the general appearance of the insect, too, is more like the Cryptini.

The type of the genus is Cryptus xanthopus, Bé., Hymén., iv., 194; Tosquinet, Mém. Soc. Ent. Belg., v., 130, which is in the collection from Stellenbosch, December.

LIENELLA, Cam.

This genus of Hemitelini was described by me in the Transactions of the South African Phil. Soc., xv., 196, 1905, In the collection of the Cape Museum are some specimens which throw some light on the genus, but not enough to properly elucidate the generic distinctions. There seems to be two groups: one, represented by L. nigriceps, with a long, narrow abdominal petiole and sharply defined metanotal keels and area, of which I have only males, and, unfortunately, all of them have the apical joints of the antennæ broken off. Of this group I have to describe another new species, which differs considerably in the structure of the area on the median segment.

LIENELLA CANALICULATA, sp. nov.

Black; the pronotum, mesonotum with scutellum, and pro- and mesopleuræ, red; the sides of the second and third abdominal segments, the apex of the second broadly and of the third narrowly, testaceous; legs black; the anterior tibiæ and tarsi obscure testaceous; the hind tibiæ with a white band at the base, the white colour obscured with testaceous. Wings fuscous-violaceous, a clear hyaline cloud on the basal fourth of the anterior and on the basal half of the posterior, a squarish cloud at the stigma and a more
