Show 172 MR. M. JACOBY ON N E W [Mar. 2, straight at the base, rounded in front; anterior margin deeply concave, posterior one strongly convex; disk distantly, sides very closely and deeply punctured, especially near the anterior angles. Scutellum metallic green or brass-coloured. Elytra convex, with a deep fovea at the lateral margin below the humeral callus, and a more shallow transverse depression surrounding the fovea; surface of each elytron with ten regular rows of deep punctures, the first of which extends to only one third the length of the elytra ; these punctures diminish in depth near the apex, and partly unite at the same place; interstices perfectly smooth. Legs fulvous, with a greenish aeneous hue. Collected by M r . D'Albertis. Three specimens in m y collection. Family HALTICIN^E. Genus H O M O P H C E T A , Erichs. 13. HoMOPHffiTA MILITARIS, Sp. nOV. Elongate, widened behind, convex. Black ; head and upper parts yellowish white, more or less stained with bright rufous; elytra impunctate, shining, each elytron with a large spot at the base and another below the middle black. Length 4 lines. Hab. Zapote, Guatemala. Head longer than broad, rather flat, with a few distinct punctures across the middle and round the inner orbits of the eyes, yellowish white; the encarpee and the parts of the mouth as well as the palpi piceous; antennae black, all the joints, with the exception of the second, which is short, slender, and of nearly equal length. Sides of the thorax nearly straight; the anterior angles slightly thickened and reaching to the middle of the eyes, but not produced in shape of a tooth ; surface impunctate. Scutellum smooth. Elytra a little wider at the base than the thorax, distinctly widened posteriorly, the humeral callus but slightly depressed within ; surface impunctate or very finely punctured, only visible under a strong glass; a large round spot at the base and another more transversely shaped near the apex of each elytron of a black or dark violaceous colour, the ground-colour being either entirely yellowish white or changing into bright rufous along the sutural and lateral margins, the former having this colour generally widened in the middle and at the apex. Underside and legs black, closely but finely covered with yellowish hairs. Collections of Godman and Salvin and Jacoby. Collected by M r. Champion. This handsome species is almost identical in coloration with the Lactica macula, Fabr., from which it m a y be at once distinguished by the want of the thoracic transverse depression peculiar to all the species of the genus Lactica. In those specimens which are marked with the rufous colour the latter generally predominates at the thorax as well, so as to leave only the anterior angles of a lighter shade.
