Show 1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 285 nigro-piceo, puncto ante scutellum sat profundo ; elytris incequa-libus, grosse ac remote rugulosis, inter rug as for titer punctato-striatis, disco nigro-piceo ramos ad humeros late oblique emittente lateribus sat explanatis apiceque albido diaphanis, reticulatis. Long. 7, lat. 4 millim. Japan, Kiga and Oyama (4000 ft.) on main island (G. Lewis). Apparently not very like any species of Coptocycla recorded from Japan or Siberia, and at once to be known by its very shining surface and roughly rugulose elytra, which are, however, quite shining. The profile of the elytra is rather evenly convex; they scarcely form a point at their summit, the suture is elevated, and two rugae at this point soon diverge, but becoming united and confused with other rugae, enclose several areolets. Five specimens are all I have seen. COPTOCYCLA VESICULARIS. Coptocycla vesicularis, Thunb. Bohem. Cass. iii. p. 256; Kraatz. I.e. p. 271. " Rottmdata, convexa, flava, nitida ; prothorace lavi, basi lineis 4 longitudinali-bus, nigris, mediis subapproximatis ; elytris mediocriter subseriatimpunctatis, dorsoplagamagnacommuni, nigra, maculis numerosis circiter 26, inaqualibus, elevatis, fiavis notata; margine sat late explanato, hyalino, confertim reticulato ; abdomine medio infuscato.-Long. 6, lat. 5 millim." "Von Baly nicht als japanische Art aufgefiihrt, durch die Zeichnung des Halsschildes und der .Flgd. leicht kenntlich, die ansehnlichste der bekannten japanischen Species." The thorax has four black lines, the middle one approximate, the disk of the elytra black, with numerous (about 26) unequal, raised, yellow marks. Length 6 millim., breadth 5. I have not seen this species. COPTOCYCLA SPILOTA. Oblonga, parum rotundata, nitida, supra castaneo-rufa, marginibus fiavis; prothorace angulis externis rotundatis, basi tenuiter; maculis tribus basalibus, una disci antica, scutello, sutura, elytrorumque maculis quinque nigris; corpore subtus nigro, capite, prosterno et pectore rufis, antennis pedibusque pallide fiavis. Long. 4 | millim. Japan, Nowata, between Tokio and Nikko. Head red, antennae with joints seven to the end thicker than the basal ones. Legs short and stout, red, spotted with darker red, and coxae pitchy, abdomen and metasternum pitchy red but dark, punctured towards its apex, but the breast and prosternum almost smooth. Thorax above smooth and convex behind, but uneven, the exterior angle with raised margin, base bisinuate ; elytra bright red, but varying, in places being brick-red, in other parts yellow or chestnut-red ; suture black, but dilated into irregular spots about five in number. Three discoidal oblique spots, the middle one |
