Show 720 MR. M. JACOBY ON THE [Nov. 3, new forms amongst these families than of those genera which are included to the end of the true Chrysomelince, and further researches will no doubt greatly increase their number. A certain number ol species which are present only in single specimens seemed to me to be so closely allied to certain European forms, especially to species of the genus Lonyitarsus, which contains already a great many very difficult species, that their description would have only increased the difficulty of determination, and I have thought it best to abstain from describing them till more material was at hand. I have added a list of the Phytophagous Coleoptera of Japan (to the end of the Galerucidae) as far as at present known, so many additions having lately been made, that a clearer idea may be gathered of their number. There is, however, little doubt that this list will be in future greatly extended, and that especially still more species will be found which are inhabitants of Japan and the northern parts of Asia on one side, and the Malayan region on the other. Genus MANTURA, Stephens. M A N T U R A JAPONICA, sp. nov. Black below ; the basal joints of the antennae, tibia?, and tarsi ferruginous; above dark blue ; thorax strongly punctured ; elytra deeply punctate-striate, the interstices flat. Length 1 line. Head remotely but deeply punctured ; antennae extending beyond the base of the thorax, the first four joints fulvous, the basal one stained with bluish-black above, the terminal joints entirely of that colour. Thorax twice as broad as long, the sides straight at the base, rounded towards the apex, rather strongly deflexed; a distinctly impressed longitudinal groove extends upwards from the sides of the base to nearly the middle; disk covered with deep and strong punctures, more closely at the sides than at the middle. Elytra rather convex, subcylindrical, regularly and deeply punctate-striate. Hakodate. Allied to M. obustata, Gyll., but the head and thorax much more strongly punctured, which gives a more rugose appearance to these parts ; the punctures of the elytra are also more closely approached and of a more rounded shape. As these characters are the same in all the specimens before me, I thought it best to separate them specifically. MANTURA FULVIPES, sp. nov. Black below ; the four basal joints of the antennae, and the legs fulvous ; above blackish-blue; thorax coarsely punctured; elytra strongly punctate-striate. Length 1 line. Head deeply and rather closely punctured ; terminal joints of the antennae thickened, pitchy black ; four lower joints fulvous. Thorax transverse, very convex, the sides strongly rounded and dilated; surface closely foveolate-punctate at the sides, more remotely |
