Show 270 MR. M. JACOBY ON COLEOPTERA [May 21, congeners, partly described under the generic name Biphaulaca, account of the strongly punctured elytra and their lateral costa. HERM^EOPHAGA HAROLDI, n. sp. Metallic green; antennae (the basal joints excepted) and tarsi black; thorax broader than long, impunctate; elytra strongly punctate-striate. Length 1| line. Head impunctate, the frontal elevations very distinct and of longitudinal shape ; the carina short and acute ; antennae extending to rather more than half the length of body, the lower three joints fulvous, the first stained with black above, the third slightly longer and much thinner than the second, the others black ; thorax about one half broader than long, the sides nearly straight, the angles acute, the transverse basal groove very deep and curved at the middle, bounded by an equally deep lateral longitudinal groove, rest of the surface very shining and impunctate : elytra convex and very slightly widened posteriorly, the shoulders prominent, the base rather swollen ; the disk strongly and rather regularly and closely punctate-striate, the punctures more strongly impressed at the sides, where the interstices are also rather swollen ; the punctuation distinct to the apex. From Tolonia Tovar, Caracas (5 specimens). LL. haroldi, although closely allied to several species described by von Harold under the generic name of Diphaulaca in his ' Coleopterol. Hefte,' seems to differ principally in the strongly punctured elytra in connexion with the transversely-shaped thorax. I a m in possession of most of the types of the author, all of which differ in this respect. HERM^EOPHAGA NITIDICOLLIS, n. sp. Below piceous; above metallic greenish aeneous ; the basal joints of the antennae and the tarsi obscure fulvous; thorax impunctate; elytra finely and closely seinipunctate-striate. Length 1 line. Head impunctate ; eyes very large; frontal elevations strongly raised, the carina long and very narrow; anterior margin of the clypeus swollen, perfectly straight; antennae nearly as long as the body in the male, shorter in the female, piceous, the three basal joints obscure flavous, the third scarcely longer than the second but thinner : thorax about one half broader than long, the sides straight, the anterior angles oblique, forming a small tooth before the middle, the posterior margin with its median lobe slightly produced and rounded ; the surface with a deep and strongly sinuate transverse gooove near the base, bounded laterally by a not very distinct longitudinal groove, but continued beyond this in a more feeble degree along the sides of the thorax; the disk entirely impunctate and very shining; elytra convex, with a scarcely visible depression below the base, finely but very closely and semiregularly punctured; anterior tibiae with a small spine. Caracas. Differing from LL. nitidissima, Baly, in the dark greenish aeneous |
