Show 210 ON NEW COLEOPTERA FROM JAPAN. [Feb. 17, PHYTODECTA RUFIPES, De Geer. Taking into consideration the great variability of our European species of Gonioctena, the synonymy of which in regard to several described species is not at all cleared up at present, I have referred the specimens obtained at Nikko to the present species, although there are perhaps sufficient differences present to justify its separation. All the specimens before me are much smaller than those obtained at Hakodate and noticed and named by Mr. Baly in the Transactions of 1873; the elytral spots are obscure (although placed as in P. rufipes), in one instance confluent and occupying nearly the entire disk ; but the short antennae, punctuation of the elytra, and the entirely rufous legs agree with P. rufipes. As, however, all the six specimens are of half the size only of the last-named species, it is not improbable that they really represent another species. PHYTODECTA GRACILICORNIS ?, Kraatz. The description of one of the varieties with confluent spots, given by the author (Deutsche entom. Zeitschr. 1879), agrees so well with the three specimens contained in this collection that I must refer them to the present species. The antenna? are slender and the joints are of the same comparative length ; but the entire head, thorax, underside, and legs are black, the disk of the thorax is very finely punctured, in some specimens almost impunctate, the sides are very strongly punctured (Dr. Kraatz says nothing about the sculpture of the thorax). The elytra have the interstices either very finely punctured or impunctate, and the posterior spots areiu two specimens confluent, forming two irregular concave-shaped bauds, the posterior of which includes a small fulvous spot near the apex (as given in the author's description). The characteristic feature ©f this species, in regard to the markings of the elytra, seems to he the large sutural spot common to both elytra which is placed below the middle and is either separated or connected with the lateral spots. I have no doubt that the Japan specimens are but slight varieties of Kraatz's species, although an examination of the type alone can settle the point. PHYTODECTA NIGROPLAGIATA, Baly. This species seems to m e extremely closely allied to P. viminalis or P. rubripes, with which it agrees entirely in the pattern of the elytra ; the latter are, however, closely and distinctly punctured at the interstices, much more so than in the allied species, which will help to distinguish P. nigroplagiata. The specimens contained in Mr. Lewis's collection have all black undersides and legs as well as the five last joints of the antennae, of which Mr. Baly makes no mention. There is also a black transverse band placed at the base of the thorax, also unnoticed in Mr. Baly's description. Genus GASTROLINA, Baly. G A S T R O L I N A JAPANA, n. sp. (Plate XI. fig. 12.)
