Show 236 MR. p. O A M E R O N O N [Mar. 19, side are rounded, smooth, shining, and bare ; the eye-incision is punctured. Mandibles black, with a dull rufous band before the middle; the base and lower side thickly covered with long white hair; the apical tooth is long and rounded at the apex. Thorax covered with white hair, except on the mesonotum, where it is shorter, stiffer, aud black ; the median segment is reticulated, more closely ou the apical slope than on the base; the central area is long, contracted in the middle, and extends to the top of the apical slope. Legs thickly covered with stiff white hair ; the calcaria aud spines are pale. Wings dark violaceous; the base to the transverse basal nervure hyaline ; the 2nd cubital cellule at the top and bottom is about one half the length of the 1st; the 1st recurrent nervure is received near the base of the apical third of the cellule. The base of the petiole is black; the rest of it, the 2nd segment, and the basal half of the 3rd are bright ferruginous: the ventral keel of the petiole has a slight, rounded curve, its base is more dilated than the apex; the keel on the epipygium becomes gradually dilated towards the apex, the space between it and the outer edge is punctured; the sides are smooth, shining, and impunctate ; the pygidium is closely and rather strongly punctured, except in the middle, where it is smooth and shining ; this smooth central part becomes gradually wider towards the apex, which is depressed. SCOLIIDJ;. DISCOLIA FOVEIFRONS, sp. nov. Nigra, capite ihoraceque nigro pilosis ; alis fusco-violaceis. 3 2 . Long. 30 mm. Head only slightly shining on the vertex, the rest of it opaque; behind it is thickly covered with longish black hair. The sides of the clypeus bear deep, distinctly separated punctures ; its apex is depressed, smooth, closely punctured behind; the central part is opaque, somewhat bell-shaped, the narrow part being at the top, above the centre it is depressed. The space immediately between the antennae is opaque and impunctate; above this, on either side, is a large and strongly puuctured depression; the depressions are oblique and narrowest above. The vertex, in the centre and behind, bears scattered, deep punctures. The central part of the mesonotum is impunctate, as is also the apical in the middle; the sides and base bear scattered punctures. Scutellum and post-scutellum closely and uniformly punctured, except the apex of the former and the centre of the latter towards the apex. Median segment closely and strongly punctured; the longitudinal furrows are wide and deep. Pleurae closely and distinctly punctured, except for a large irregular space in the centre of the pro- and mesopleurae. The spines and hairs on the legs are black ; the fore calcaria are dark rufous. The abdominal segments are sparsely, slightly, and irregularly puuctured; the hypopygium is coarsely punctured, except at the apex. The wings are deep violaceous, very highly iridescent, and with greenish tints towards the apex. |
