AUSTRALIAN COLEOPTERA. NOTES AND NEW SPECIES. VIII. By H. J. Carter, B.A., F.E.S. (Eight Text-figures.) [Read 31st May, 1933.] Family Buprestidae. Stigmodera (Castiarina) subtincta, n. sp. Oblong-ovate. Head, pronotum, scutellum, appendages and the greater part of underside golden green; elytra, save for the dark basal border, yellow with an orange tint — the latter especially around the apex; the apical four segments of abdomen yellow, sometimes showing faint metallic gleams. Head deeply excavate and channelled, densely punctate. Prothorax: Apex feebly, base more decidedly bisinuate, sides widely bulging at posterior third, thence lightly converging to apex and more abruptly and subsinuately to base; front angles acute, hind rectangular, medial line shown by a short sulcus near apex and a smooth line on basal half; disc strongly, irregularly punctate, the postero-lateral punctures coarse, contiguous and subrugose, elsewhere the punctures becoming smaller, dense near apex, more distant towards base. Scutellum with about six small punctures. Elytra widening at shoulders, lightly compressed behind them, widest near middle, each strongly bidentate at apex, with long external spine; margins entire, seriate punctures large and round in four sutural rows, much smaller in the rest; intervals almost flat and impunctate throughout. Flanks of pro-and metasternum coarsely punctate, the middle areas much more finely so; abdomen glabrous with very fine shallow punctures. Dimensions: 15 X 5 mm. Habitat. — Western Australia: Lake Grace (H. W. Brown). This and the following species sent by that indefatigable collector, Mr. Horace Brown, add to an increasing group having wholly or almost wholly yellow elytra — Nos. 13-18 in my Revision (Aicst. Zool., 1931, p. 350). The above species is distinguished from all of these except intacta mihi, bj^ its strong apical spines. From intacta it is distinct by its smaller size, flatter form, and very different prothorax. Holotype in Coll. Carter. Stigmodera (Castiarina) subnotata, n. sp. Oblong-ovate. Head, pronotum, scutellum, appendages and underside — except abdomen — golden green (pronotum more golden than green), elytra and abdomen testaceous, the former with a small black postmedial spot on the seventh interval. Head excavate and channelled, finely, closely punctate. Prothorax: Apex lightly, base more strongly bisinuate, sides moderately and nearly evenly rounded, widest at middle, all angles rather wide; discal punctures fine and dense on apical half, larger and more distant towards base, coarse near hind angles; medial line only indicated by smooth area near base. Elytra lightly enlarged
