Show 204 MR. M. JACOBY O N N E W [Feb. 17, Head with an obsolete median longitudinal groove, closely and finely rugose-punctate. Antenna? two thirds the length of the body, slender and filiform, the second joint distinctly shorter than the first, the third more than twice as long as the preceding, basal joint stained with piceous above, the two or three following fulvous, the rest dark piceous or black. Thorax subcylindrical, scarcely broader than long, the lateral margin entirely absent; surface sculptured like the head, obsoletely transversely depressed across the base. Elytra more strongly punctured, the punctuation arranged in very closely approached rows, the interspaces here and there obsoletely raised, surface covered with a thick layer of white powder, when rubbed shining black. Legs black, extreme apex of the tibiae and the tarsi obscure fulvous. Femora armed with a smooth tooth. Oyama, Kiga, Oguma, Nikko. In size this species agrees with L. lewisi, Baly, and L. fulvus, Baly, but is quite distinct from either of them. The general colour is entirely black ; and the insect, when captured, is covered with a thick layer of white powdery matter which entirely hides the punctuation from view; when rubbed, the elytra, unlike L. lewisi, are shining black and not covered with pubescence. In the latter species there is a finely but distinctly marked lateral margin to the thorax, which in the present insect is totally absent; the punctuation of the head and thorax also is much more finely rugose, the antennae are proportionately longer and have the three or four lower joints fulvous. Genus DEMOTINA, Baly. D E M O T I N A BIPUNCTATA, sp. nov. Narrowly oblong, obscure fulvo-piceous, closely covered with white pubescence; antennae and legs fulvous; head, the sides of the thorax and elytra, and a small spot at the middle of each elytron, whitish. Length 1| line. This species, although closely allied to D. modesta, Baly, is yet quite distinct. The antennae are less robust, the thorax is rather more transverse, the pubescence which covers the entire upper surface is not fuscous as in the allied species, but white, covering the entire head thickly, and forming a band at the lateral and anterior margin of the thorax as well as at the sides of the elytra, while a small spot of white hairs is placed near the middle of each elytron ; the punctuation of the latter as far as visible seems to be arranged in very closely approached rows. The intermediate tibiae are obsoletely notched at their apex ; claws bifid; femora with a minute tooth. Kobe. A single specimen was obtained by Mr. Lewis during his first journey, a second one at the last visit to Japan. The species is closely allied to D. modesta, Baly; but is of smaller and less robust size, and distinguished by the white pubescence in forms of stripes and spots on the elytra. D. decorata, Baly, is smaller still, of different coloration and with comparatively short antennae. |
