Show 1902.] OF AMERICAN COLEOPTERA. 181 mediate space very narrow, the frontal tubercles small, the carina acute, the clypeus triangularly raised ; labrum flavous, as well as the palpi; antennae extending to the middle of the elytra, flavous, the last two joints wanting, the second joint half the length of the third; thorax twice as broad as long, narrowed to a slight degree anteriorly, the sides straight, the anterior angles oblique, the disc impunctate, flavous; the basal sulcus very deep, sinuate, and placed rather closely near the basal margin ; scutellum rather broad; elytra convex, elongate and widened towards the middle, not perceptibly punctured; below and the legs flavous. Hab. Espirito Santo, Brazil. Evidently allied to L. capitata Illig., but rather smaller, more convex, the antennae and the labrum entirely flavous, the first-named shorter, the eyes still larger, and the elytra reddish-fulvous, not testaceous. LACTICA RUFO-BASALIS, sp. n. Elongate, parallel, flavous ; the antennae (the basal joint excepted) black; head and thorax reddish, impunctate, the basal sulcus very deep; elytra impunctate, flavous, the base reddish fulvous ; below and the legs flavous. Length 7 millim. Head impunctate, reddish fulvous, very shining, the frontal tubercles rather obsolete, carina acute and narrow; eyes large, coarsely granulate, the intermediate space not broader than their diameter; antennae extending beyond the middle of the elytra, black, the basal joint flavous, the third joint twice as long as the second, but shorter than the fourth joint; thorax about one-half broader than long, slightly nan-owed anteriorly, the sides straight, with a rather broad, reflexed margin, the anterior angles oblique, the disc extremely shining, impunctate, the basal sulcus very deep, placed at some distance from the base, the lateral perpendicular grooves still deeper; elytra subcylindrical, scarcely widened at the middle, not distinctly punctured but crowded with numerous'piceous specks, the basal margin reddish, the rest of the surface flavous, the metatarsus of the posterior legs as long as the following joints together. Hab. Tejuca, Brazil. This is a large-sized species, of which a single example is in my collection. It is distinguished by the coloration of the head, thorax, and elytra, the flavous legs, and very deep thoracic sulcus. LACTICA FEMORATA, sp. n. Flavous, elytra rufous, the posterior femora piceous ; head and thorax impunctate, the basal sulcus very deep and sinuate, elytra impunctate. Length 2£ millim. Head impunctate, eyes large, entire, frontal elevations obsolete, carina short, acute; antennae entirely fulvous, extending beyond |
