Length 2\ lines. Hab. Brit. Honduras (Blancaneau). Head almost flat, with an indistinct median depression, extremely minutely granulose and punctate ; labrum black ; antennae black, second and third joint fulvous. Thorax of usual shape ; its sides perfectly straight; surface distinctly punctured, the punctures becoming deeper near the base. Scutellum black. Elytra not wider at the base than the thorax, narrowed and rounded posteriorly; each elytron with ten rows of deep punctures, which become rather finer towards the apex ; lateral lobes angulate. Prosternum black, slightly longer than broad, impressed with some distinct punctures. Closely allied to L. cyaneum, Lac, but differing in the want of the anterior depression at the head ; the latter is at the same time impunctate and very finely granulate ; the thorax is much less strongly punctured than in L. cyaneum, and its lateral margins are straight instead of rounded.
