Show 214 MR. C O. WATERHOUSE ON COLEOPTERA [Apr. 1, than broad and densely covered with hair ; the outer lobe a little beyond the inner one, the apex with dense matted hair, with four or five stiff bristles on the outer side. Basal joint of the maxillary palpi short; the second and third stout, about twice as long as broad, narrowed at the base ; the apical joint narrower than the preceding, acuminate at the apex. The labrum about twice as long as broad, membranous, the middle of the front margin very deeply incised, fringed with stiff hair, and with some long stiff bristles arising from behind the margin. The anterior angles of the thorax are very much directed downwards and are rather obtuse, and are not visible when viewing the insect from above, in which position the thorax has a nearly circular outline. The under reflexed shining margins parallel as far as the front angles. Intermediate coxae slightly separated. Tarsi rather slender. DIAPHCETES RUGOSUS, n. sp. (Plate XVI. fig. 1.) Nearly black ; sparingly clothed with pubescence, which is chiefly brown, but on the shoulders of the elytra, the basal segment of the abdomen, and the margin of the penultimate segment, and on the tibiae is golden. Head, thorax, and elytra densely and very strongly punctured, the punctures on the disk of the thorax having a tendency to run together longitudinally. The punctuation of the abdomen is much less strong and less close. Head a little broader than long, about two thirds the width of the thorax ; the cheek behind each eye is much less than the length of the eye, the posterior angle rounded. Thorax rounded at the sides and behind ; in the middle of the base there is a short smooth spot. Elytra as long as the thorax, but distinctly broader, with an indication of a sutural stria. Legs pubescent, the middle tibiae beset with small blackish spines on the outer side. Length 6 lines. Hab. Larat. PASSALID^E. LEPTAULAX TIMORIENSIS, Perch.
