Show 1901.] HYMENOPTERA FROM NEW BRITAIN. 239 and blunt. Thorax thickly covered with depressed golden pubescence ; the sternum, the base of the meso- and metapleurae, the space between the scutellums and the wings, and the base of the median segment are black. The sides of the pronotum are broadly rounded behind ; the post-scutellum is raised above the level of the scutellum, and is clearly separated from it by a wide, rounded depression ; its top is smooth and shining. The metanotal tubercles are large, prominent, bluntly rounded above ; the basal and apical slopes are about equal in length. The wings have a slight violaceous tinge ; the first and second transverse cubital nervures above are separated by a slightly greater distance than the second is from the third; the third transverse cubital nervure has a rounded slope; the first recurrent nervure is distinctly separated from the transverse cubital; the second is received shortly behind the apex of the basal third of the cellule. Except for black marks on the four posterior coxae behind and a broad black line on the hinder femora, the legs are coloured like the body; the single tooth on the claws is large, stout, and curved. Abdomen black, with a plumbeous hue; the petiole luteous, black at the base and apex ; the penultimate ventral segment is thickly covered with long black hairs. This species is only represented by males. It is certainly not the male of S. insularis, as apart from the marked difference in coloration, the two differ in important structural characters not of a sexual nature, e. g. in S. basimacula the post-scutellura is raised above the level of the scutellum, which is not the case with insularis. SALIUS WILLEYI, sp. nov. Luteus, abdomine nigro; alis violaceis; antennis nigris, basi luteis. 8 - Long. 12 mm. Antennae black, the scape clear, the base of the flagellum dark luteous; the third joint is shortly, but distinctly, longer than the fourth. On the head the vertex, the occiput, and the front, except at the sides, are black. Eyes distinctly curved on the inner side; the ocelli form a triangle, the hinder are separated from each other by a distinctly less distance than they are from the eyes. Apex of clypeus broadly rounded. The apical tooth of the mandibles is large, triangular; the lower oblique, not projecting. Prothorax broadly rounded at the base. The thorax has the following parts black :-the mesonotum except in the middle behind, the space at the sides of the scutellums, the median segment broadly on the basal half, the apex slightly in the middle, the mesosternum, the lower half of the mesopleurae at tbe base, and the metapleurae except at the apex. Post-scutellum and scutellum roundly convex ; the former is large and is on a level with the scutellum. The median segment is not transversely striated ; the tubercles are large and rounded. Wings uniformly fuscous violaceous, strongly iridescent; the cubital cellules are equal |
