Show 184 MR. MARTIN JACOBY O N N E W SPECIES [Mar. 4, the elytra, black, the lower three joints flavous, basal joint elongate, the second and third nearly equal, the latter, however, much thinner, the following joints very elongate, the last three thinner than the preceding joints; thorax rather more than twice as broad as long, the sides very feebly rounded, the anterior angles not oblique, the disc impunctate with a transverse impression at the sides near the anterior angles, basal sulcus deep and sinuate, closely placed to the basal margin; elytra convex, with a very shallow depression below the base, extremely minutely and irregularly punctured ; underside and the legs flavous. Hab. Mexico. Of this species I received two specimens from M. Deyrolle, which had been found in Mexican tobacco. The small size, very slender antennae, the anterior thoracic fovea, and the entirely flavous legs will assist in its recognition. LACTICA CARINATA, sp. n. Entirely testaceous, of elongate shape; head with a transverse ridge; thorax impunctate, not very transverse, basal sulcus deep and straight; elytra not perceptibly punctured. Length 41- millim. Head impunctate ; frontal elevations obsolete, replaced by a transverse ridge between the eyes ; the latter very large, occupying the entire sides of the head ; clypeus strongly and acutely raised between the antennae; the latter extending beyond the middle of the elytra, entirely testaceous, the third joint one-half longer than the second, but much shorter than the fourth joint; thorax scarcely twice as broad as long, slightly narrowed anteriorly, the sides nearly straight, with a narrow reflexed margin, the anterior angles oblique, but not produced, the basal sulcus and the perpendicular grooves deep, the disc impunctate; elytra nearly parallel, impunctate ; below and the legs coloured like the upper parts, the metatarsus of the posterior legs elongate. Hab. Cayenne. There will be no difficulty in distinguishing this species from its allies on account of the transverse ridge between the eyes and the unicolorous legs. I know only a single specimen of this species, which is in m y collection. LACTICA IMPRESSICOLLIS, sp. n. Ovate, fulvous, the antennae (the lower three joints excepted) black ; thorax transverse, with an antemedial transverse depression at the sides, the basal sulcus deep and sinuate; elytra with a shallow depression below the base, impunctate ; legs fulvous. Length 4 millim. Head deeply punctured near the eyes, the latter large, strongly emarginate, the intra-ocular space raised in two elevations; clypeus bluntly elevated; antennae extending beyond the middle of the elytra, black, the lower three joints flavous, the second one-half shorter than the third joint, the others closely pubescent |
