APOGONIA SULCATICEPS. 29 NOTE III. THREE NEW SPECIES OF THE MELOLONTHID GENUS APOGONIA DESCRIBED BY C. RITSEMA Cz. Apogonia sulcaticeps, n. sp. Resembling A. laevicollis Lansb. from Java and Sumatra, but at once distinguished from that species by the clypeus which is shorter, deeply emarginate in the middle and, between the eyes, separated from the face by a deep sulcus. Moreover the punctuation ou the elytra is stronger. Length 7,5 — 8,5 mm. — Broadly ovate; glabrous, black, the head, prouotum and scutellum with green and purple or coppery tinges, the antennae and palpi pale ferruginous, the tarsi pitchy brown. The head is large, the clypeus broadly emarginate in the middle, the emargination with rounded lateral angles, the anterior margin reflexed ; a deep sulcus between the eyes separates the clypeus from the face; the clypeus is rather remotely covered with large punctures ; the punctures on the face are fine and distant. The prothorax is strongly transverse and very convex ; the pronotum is distantly covered with punctures which are a trifle larger than those on the face ; a small impres-sion is present at the basal margin in front of the basal angles of the scutellum; the sides are rounded just behind the middle when viewed laterally, the basal angles are obtuse, the anterior ones acute but not protruding.
