Show 1885.] COLEOPTERA FROM JAPAN. 203 CRYPTOCEPHALUS SEXPUNCTATUS, Linn. A single specimen before me I am unable to separate from the normally coloured individuals of this species, which has been reported also from Siberia. CRYPTOCEPHALUS FULCRATUS, Germ. The occurrence of this species in Japan extends still further its geographical distribution, it having been also recorded, like the preceding species, from Siberia. Two specimens obtained at Jensai do not differ from the European form except in their rather larger size. CRYPTOCEPHALUS NOBILIS, Kraatz. (Plate XI. fig. 7.) The description of this species, given by the author in the 'Deutsche ent. Zeitschr.' 1879, agrees perfectly with the ten specimens obtained by Mr. Lewis at Kiga, Suyama, and Subashiri. The insect is of a shining black colour, with two transversely shaped yellow spots at each elytron (one slightly before the middle, the other at the apex). The antennae in the male are exactly as long as the body, but shorter in the female, and the four or five lower joints are testaceous; the punctuation of the elytra is strong, and arranged in close but not very regular rows. The specimens which served Mr. Kraatz for his description were obtained from the Amur country. Genus PACHYBRACHYS, Suffr. PACHYBRACHYS ERUDITA, Baly. Pachybrachys donitzi ?, Harold. A great many specimens of this apparently very variable species were obtained ai Tensai, Wada toge, Nikko, Kurigahara, on sallow. The specimens which served Mr. Baly for his type have the elytra almost spotless ; between this and almost black-coloured individuals there is every intermediate degree before me, the most frequent form being that in which the disk of the elytra is occupied by a longitu-diual broad piceous or black band, leaving only the sutural and lateral margin of the testaceous ground-colour ; the thorax varies equally in colour, from a well-distinguished M-shaped mark to being almost black with two narrow yellow basal spots. I have no doubt that one of these named varieties is identical with P. donitzi, Harold, as all other characters agree with the description of this author. Genus LEPROTES, Baly. LEPROTES PULVERULENTUS, n. sp. (Plate X L fig. 9.) Obion0-, black, covered with white excrescences ; three basal joints of the antennae and the labrum fulvous. Head and thorax finely rugose-punctate ; elytra more strongly semipunctate-striate. Length 3-3| lines. |
