DESCRIPTIONS OF NEW SPECIES OF AUSTRALIAN COLEOPTERA. XXI. By Arthur M. Lea, F.E.S. [Read 24th September, 1930.] In addition to truly Australian forms, five others from Fiji and Papua are herein described, but they are closely allied to Australian forms. Family Scarabaeidae. DiPHUCEPHALA GLABRA, n. Sp. ^. Green, coppery-green or coppery; elytra red with a green or coppery-green gloss, lower surface of clypeus blackish; antennae (club black), palpi, and legs (claws infuscated) reddish. Upper surface glabrous, under surface, pygidium and legs with rather dense white setae. Head with crowded and rather shallow punctures. Clypeus almost parallel-sided, apex widely notched, front half with sparser and smaller punctures than elsewhere. Prothorax moderately transverse, with a wide median impression, evenly narrowed to apex, each side with a transverse fovea, outside of which is a strong but not very acute tooth; with large and comparatively sparse punctures, each with a central granule. Scutellum polished and impunctate. Elytra with slightly elevated lines, and coarse crowded punctures, larger across middle than elsewhere. Front tibiae bidentate at and near apex, front tarsi with four basal joints wider than those of other tarsi. Length, 8-& mm. New South "Wales: Eccleston (J. Hopson). The longitudinal sulcus of the pronotum is wide, fairly deep and continuous almost to apex, much as on D. richmonclia, from which, as from most of the red-legged species, it is distinct by its glabrous upper surface. D. pulcherrima and D. hirtipes have parts of the prothorax densely squamose and are otherwise very different. The lateral foveae of the pronotum are usually isolated, but on several specimens there is a vague line connecting each of them with the median impres-sion. I have not seen a female of this species, but there are nineteen males under examination. DiPHUCEPHALA DICKSONIAE, U. Sp. cj". Metallic-green or coppery-green; elytra reddish with a green or coppery-green gloss, legs reddish, tarsi, antennae (except part of basal joint), palpi, and lower surface of clypeus black or blackish. Upper surface with rather sparse, uniform, white, depressed setae, becoming denser and longer on under surface and legs. Head coarsely shagreened, punctures fairly distinct only on a semicircular space connecting the hind parts of the eyes. Clypeus with sides gently incurved to middle, apex deeply notched. Prothorax moderately transverse, median sulcus J
