JACOBY ON NEW COLEOPTERA. 519 broad,ly rounded, and the anterior angles subrotundate; the disk c~)l1tall1s some remote but strongly marked punctures, while the sIdes and ~he commencement of the posterior margin is strongly impressed wl,th large punctures, distinctly visible to the naked eye; surface untformly darkish brown. Scutellum elongate, trianO'ular, smooth, black. Elytra scarcely wider at the base than the thorax, slightly widened behind the middle, surface rather convex; they are regularly striate-punctate on their inner half, while the outer portion contains numerous irregularly distributed punctures, not so deeply impressed as those near the suture, of a light testaceons colom, the sutme and four spots on each elytron of a greenish black colour, and placed as follows :-two longitudinal streaks, a little widened at their extremities a little below the base, of equal size, one of which is situated near the scutellum, the other near -the exterior margin; a transverse vitta a little behind the middle, not touching the l?teral nor the sutural margin, sinuate in middle, and forming at the sutural end a short angle parallel with the suture; and another short oblique spot near the apex: this spot is sometimes connected with the transverse vitta by a thin line. Body below shining cupreous, with a greenish tinge. Abdominal segments each with a shallow fovea near the sides. f7 at'. ct. The spots on the elytra not much darker than the ground-colour, and indistinct (immature ?). Length 4t lines. Hab. Chontales, Nicaragua. Collected by Mr. Janson. Although this beetle is, in the punctuati(ln and markings of the elytra, quite different from other species belonging to this genus, its structural characters agree in every particular. 17.
