Show 652 ON THE JAPANESE ENDOMYCHIDAE. [Dec. 20, species; but, so far as can be seen without dissection, the palpi, especially the maxillary pair, have their apical joint wider and more triangular than in Symbiotes, in which they are oblong and truncate ; but not at all securiform. 1. CHONDRIA LUTEA, n. sp. Breviter oblonga, lutiuscula, pallide ferruginea unicolor, pubescens; prothorace transverso, lateribus fortiter rotundatis, late marginatis, limbo crenulato, disco lavi, basi profunde bisulcata, elytris leviter punctato-striatis. Long. 2| millim. Hab. K I U S H I U : Nagasaki. The head is quite sunk in the thorax, of which the prominent front angles, formed by the broad margin, completely surround it, except in front; the eyes are coarsely granulate. The antennae are entirely red, their second to eighth joints short, the ninth and tenth as broad as long and of the same form, the apical joint nearly twice as long, compressed at the tip. Thorax twice as broad as long (if the anterior angles are excluded), sides rounded and contracted into the anterior prominent angles, the flattened margin broad and slightly concave, the outer edge being a little reflexed and faintly crenulate, basal sulci impressed as small fossae on the basal margin, and thence continued as lines about halfway across the disk. Elytra punctate-striate, the striae continued to the apex, but the internal ones united before the apex. Pubescence rather thick and pilose, of the same luteous colour as the whole insect. Two examples, found in haystack-refuse. SYMBIOTES, Redtenbacher. 1. S Y M B I O T E S NIPONENSIS, Gorh. Ent. M o . Mag. vol. x. p. 225. Hub. K I U S H I U : Nagasaki. C H I N A : Kiu-kiang on the Yangtse-kiang river (Leicis). This curious little insect was met with commonly by Mr. Lewis in the neighbourhood of Nagasaki, in haystack and other refuse : it was also originally found by him in China; but the latter locality was omitted by oversight. 2. SYMBIOTES? ORBICULARIS, n. sp. Orbicularis, convexus, fere hemispharicus, cinereo-pilosus, brunneus; thorace brevi, basi profunde bisulcata; elytris sat crebre fortius punctatis, haud striatis. Long. If millim. Hab. M A I N ISLAND : Kashiwagi, Kurigahara. Larger and more orbiculate than S. niponensis and, moreover, at once to be distinguished from it by the punctuation of the elytra, which is not in strice, but dispersed. The whole insect is rusty red ; the antennae are formed as in S. niponensis, the two basal (especially the first) joints being stout, the intermediate ones very .-mall and linear, gradually shortening from the third (the longest) to the seventh, which is quadrate. The three apical joints are subequal, nearly quadrate, forming an elongate, stout club. The head and |
