Show 1887.] JAPANESE ENDOMYCHID/E. 651 found, some showing more or less tendency to becoming four-spotted, but only two or three definitely four-spotted varieties. Sexual distinction not apparent. 3. CYANAUGES QUADRA, n. sp. (Plate LIII. fig. 8.) Niger, nitidus, elytris latius ovatis, singulis maculis duabus ornatis, una humerali, una subapicali, flavis. Long. 5 millim. Hab. M A I N ISLAND : Kashiwagi. Black, elytra each with two orange-yellow spots, one on the shoulder, and one larger and transverse near the apex. Head and thorax impunctate, the latter narrow, basal sulci distinct and deep, a little arcuate and simple (i. e. not bisu'cate at the base), the sides narrowing from the base and sinuous, front margin between the angles nearly straight. Elytra thickly but quite distinctly punctulate; their widest part is below the middle; apex broadly rounded. The antennae have their fourth and subsequent joints short, but not transverse, the third nearly equal to the fourth and fifth taken together. A single specimen. 4. CYANAUGES NIGROPICEUS, n. sp. (Plate LIII. fig. 7.) Niger ; ore, elytris, pedibus et corpore subtus saturate nigro-piceis, abdominis apice ditutius piceo. Long. 4 millim. Hab. M A I N I S L A N D : Kashiwagi. Very like C. gorhami; compared with which it is a rather shoiter and broader insect, and without any of the blue tinge which characteiizes that species. The thorax is twice as wide as long, very smooth, the disk rather convex, the basal sulci distinct and half the length of tne disk, quite as in C. gorhami, except that it is wider and altogether rather larger. Elytra punctured, but rather faintly so, black, but with a pitchy tinge, less ovate and more broadly rounded behind than in C. gorhami. Antennae with joint 4 very little shorter than 3 ; 5-8 longer than wide but gradually shorter. Abdomen becoming gradually lighter in colour from the base to the apex. Three specimens. CHONDRIA, n. gen. Tarsi quadriarticulati, haud lobati. Prosternum processu inter-coxali angusto, lanceolato, marginato. Pronotum late marginatum ut in genere Stenotarso, margine deplanato concavo, limbo crenulato. Antennis articulo nono et decimo subquadratis aqualiter lutis, ultimo oblongo, apice acuminato. This new name is proposed for a genus of the family Endomychidae, allied on one hand to Stenotarsus by the broad flat margin of the thorax, but more closely, in general structure, especially by that of the tarsi, to Symbiotes. The tarsi are quite simple, i. e. without a long bilobed second joint as in Stenotarsus. The prosternum entirely agrees with that of Symbiotes. Of the trophi 1 cannot speak particularly, there being only two specimens of the single |
