Metanotura black, thickly covered with pale down and more sparsely with longish fuscous hair; the striation is as usual; iu the middle are two large, somewhat oval fulvous marks, which, on the outer side of their apex, are prolonged to near the end of the segment. The mesosternum and the basal half of tbe mesopleurae are black; the black on the latter is roundly incised on the apex above. Metapleurae black, except on the apical third. Legs coloured like the antennae ; the tarsi have a yellowish, paler tint; the claws have one stout tooth at the base. Wings yellowish hyaline with a violaceous tinge; the space bounded by the tips of the 1st and 2nd transverse cubital nervures is almost equal in length to that bounded by the 2nd and 3rd; the apices of both wings are very narrowly bounded by a fuscous cloud. Abdomen entirely black; tbe ventral surface sparsely, the hypopygium and epipygium more thickly covered with long black hairs. The 3rd transverse cubital nervure is roundly and broadly curved ; the 2nd transverse cubital nervure is received at the apex of the basal third of the cellule ; the 2nd recurrent nervure has the lower part straight and obliquely bent backwards; the 2nd submedian nervure in the fore wings is received distinctly behind the middle of the discoidal cellule; the 1st recurrent nervure is not quite interstitial, as it is in some of the species of the Mygnimia section, it being received shortly, but distinctly, behind the transverse cubital; the apical tooth of the mandibles is blunter, broader, and more rounded than in most of the species, than in, e. g., S. ceg-lonicus and S.fiavus ; and the apex of the clypeus is more rounded, not so broadly transverse in the middle, than it is in the two species just mentioned; the sides of the pronotum do not bulge out roundly as in S. fiavus; the metanotal tubercles are large and prominent, on the base they have a longer and more oblique slope than on the apex, where the slope is much more abrupt; the furrow on the mesopleurae is straight and oblique and ends behind in a distinct fovea. SALIUS BASIMACULA, sp. nov. Fiavus; abdomine nigro, petiolo late fiavo balteato, femoribus posticis supra late nigro-lineatis ; alis fiavo-hgalinis. 3 . Long. 17 mm. Antennae pale yellow ; the third joint is shortly but distinctly longer than the fourth, which is not quite so long as the vertex between the eyes. The ocelli are in a triangle, the hinder are separated from each other by half the distance they are from the eyes, which converge only very slightly on the lower side. The vertex across the ocellar region is black, the black line enclosing all the ocelli. The whole head is covered with depressed golden pubescence, and more sparsely with long pale hairs ; the apex of the clypeus is transverse, with the sides broadly rounded ; the apical tooth of the mandibles is triangular, the subapical is short |
