Hab. Madagascar, Diego-Suarez (Ch. Alluaud). Neodera was founded by Duvivier on some nearly similarly coloured species of Halticidas, agreeing in the main points with Pseudodera and Crepldodera, but differing in the total absence of any punctuation, the shape of the thorax and its sulcus, which resembles somewhat that of Phygasla. I am unable to discover any spines on the anterior tibias, and those at the posterior ones are very small; the tibiae are not channelled. The present insect differs from its aides and those described by v. Harold as Crepldodera (picticornis, varicornis, and madagassa) by the colour of the antennas, which is the same in three specimens before me. NEODERA TRANSVERSICOLLIS, n. sp. (Elate XXXIV. fig. 6.) Fulvous, the last seven joints of the antennae black; thorax transverse, impunctate; elytra with some punctures near the suture only. Length 3 lines. It will only be necessary to point out the differences between this species and the preceding, which it otherwise resembles. It is a much larger insect; the antennae have only the four lower joints fulvous, the others are black and rather short; the thorax is nearly twice as broad as long, the anterior angles are produced obliquely outwards, and the basal sulcus is very deep and broad; the elytra show a row of punctures close to the suture as far as the middle : the tarsi are obscure piceous. Hab. Madagascar. A single female specimen (coll. Jacoby). GALERUCINJE. L U P E R U S GIGANTEUS, n. sp. Metallic blue; thorax transverse, nearly impunctate; elytra very finely and closely punctured. Length 3|-4 lines. Head wdth a few extremely fine punctures near the eyes, the latter very large, frontal elevations transverse; clypeus distinctly swollen ; labrum black, its anterior edge flavous; antennas extending beyond the middle of the elytra, black, the lower three |
