NOTES ON AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES. Part i. By Charles Oke. [Read 28th March, 1928.] Staphylinidae. Dabra sulcicollts, n. sp. Testaceous; liead and elytra dingy-brown; prothorax castaneous; first, second and eleventh joints of antennae and tarsi flavous, intermediate antennal joints infuscated. Clothed with pale ashen pubescence, tips of abdominal segments with a row of moderately long hairs. Head strongly transverse, narrowed in front, indistinctly punctured. Antennae with first joint large, second about half length of first, thin at base, thickened near apex, third to tenth transverse, increasing in width, eleventh as long as preceding four combined, rounded at apex. Thorax transverse,, base bisinuate, with the hind angles produced and having three or four stout setae; a large medio-basal impression continued to apex; fine confiuent punctures. Elytra strongly transverse; posterior margin quadri-sinuate with the lateral angles produced; sculpture finer and more indistinct than on pronotum. Abdomen tapering, smooth and shining on basal joints, apical and subapical rather closely punctured. Under surface closely punctured. Length, 3-80 mm. Hah. — Victoria: Gypsum, in nests of Iriclomyrmex nitidus (C. Oke). Distinguished from the previously described species by the impression on pronotum. Viewed from some directions this appears to be an isolated round fovea somewhat obliquely impressed on the pronotum, but when viewed obliquely from the sides it appears as a medial sulcus dilated near the base. Type in author's collection. QUEDIUS BELGRAVEJN'SIS, n. Sp. (^. Dingy reddish-brown, in parts infuscated; legs and tips of abdominal segments paler, head and pronotum black, elytra and mandibles pale testaceous, two basal joints of antennae (the others much infuscated), palpi and tarsi flavous. Elytra, abdomen and sternum rather thickly clothed with pale adpressed pubescence; sides of head, prothorax and abdomen with scattered long black hairs. Head, excluding neck, transverse, convex, rounded on sides; eyes large, same length as inter-antennary space; two punctures at base of each antenna, a small puncture near eye, and a larger one between eye and neck. Antennae with first joint long, second slightly longer than third, fourth smaller, fifth and sixth quadrate, seventh to tenth transverse, eleventh ovate-acuminate, lightly incurved at apex. Prothorax a little wider than long, widest near base; with two punctures nearer apex than usual. Elytra quadrate, with rather close ^1
