Niger ; palpis (apicibus exceptis) pedibusque basi obscure testaceis capite, prothorace elytrisque apicibus cinereo-tomentosis ; scutello, elytrorum basi, linea obliqua cum hoc conjuncta, fascia intus abbreviata, arena communi, et fascia subapicali recta albo-squamosis; elytris basi fortiter, lateribus et versus apicem crebrius minus fortiter punctatis. Long. 9 millim. Hab. Burmah, Karen Mountains (Boherty). The head and thorax in this species are almost entirely covered with ashy-grey close hairs, resembling scales, and perhaps in part really these are scales; the thorax is very even, scarcely constricted in front, and with the posterior part very gently rounded to the base, the margin is there raised and polished in the middle, and there is a small denuded mark in the centre of the base, before the margin slightly impressed. It is half as long again as wide. The pattern of the elytra is very elegant, but hard to express in words. The basal scales and first oblique mark form an x, with the top straight, then almost united to this is a mark like - \j-, the y being common to the two elytra; then a straight and entire fascia at about one third from the apex, slightly thickened on the suture, and the apex itself ashy, and the ashy scales joining the fascia. Legs black, except the trochanters and extreme base of the thighs. Four specimens. CALLIMERUS HYDNOCEROIDES, n. sp. Nigro-cceruleus, nitidus; ore, antennis, palpis pedibusque testaceis; elytris nigris, dimidio basali intus aureo-testaceo, sutura justice punctisque nonnullis albo-squamosis ; capnte p>rothoraceque parce et profunde, elytris cbsoletius crebre punctatis. Long. 8*5-9 millim. Hah. Burmab, Ruby Mines (Boherty). Head blue-black, with white scales in front, very sparingly punctured and shining; thorax strongly constricted, and widely lobed at the sides, an impression on each lobe, and one in the middle of the base which is smooth and polished ; there are a few white scales on each side in the anterior constriction, the colour is blue-black, the punctuation strong and distinct. The elytra are depressed at their base, black or brownish, this colour extending up the margin to the base, but of a sordid yellow within (the suture narrowly dark) and almost to their apices. The white scales border the suture sometimes in the apical half. In the basal half there are normally six white spots, four in pairs near the suture and between them, one nearer the margin on each elytron on the black part, and there is one lateral subapical spot, sometimes joined with the sutural scales, forming the 7 mark so common in this genus. But these spots are feebly scaled and liable to be worn off, and the central pair may be absorbed in the sutural line. Scutellum white. The hind thighs have the small tooth near their apices. The underside is blue-black, with the |
