Show 282 MR. M. JACOBY ON COLEOPTERA [May 21, latter bifoveolate; elytra metallic green, rugosely punctured, the lateral and apical margin flavous. Male. Elytra with an elongate tubercle near the apex. Length 2\ lines. Male. Head impunctate, entirely fulvous, with a small fovea between the antennae ; the clypeus transversely subquadrate, sparingly pubescent, labrum and palpi flavous ; antennae two thirds the length of the body, black (the two penultimate joints in the female flavous), the basal joint flavous below, the third more than double the length of the second ; thorax twice as broad as long, the sides but slightly rounded before the middle, the surface impunctate, fulvous, shining, with a deep fovea at each side ; scutellum flavous; elytra dark metallic green, the disk transversely wrinkled and rugose, with some narrow longitudinal costae and a strongly raised longitudinal tubercle near the apex, the lateral margin narrowly, the apical one more broadly, flavous ; underside and the upper edge of the femora and tibia? as well as the tarsi entirely black. San Esteban. Allied to B. ambitiosa, Erichs., D. puncticollis, Baly, and several other species, but differing from all in the metallic elytra and the different system of coloration, especially in the black underside. DIABROTICA VARICORNIS, n. sp. Fulvous; intermediate joints of the antennae black ; thorax bifoveolate ; elytra finely punctured, a ring-shaped mark at the base and another semilunate one near the apex as well as the breast black. Length 3 lines. Head impunctate, fulvous; labrum black; antennae elongate, extending to two thirds of the length of the elytra, fulvous, the fourth and the following five joints fuscous or black, the second joint short, the third slightly longer ; thorax impunctate, nearly as long as broad, the surface with two deep foveae; scutellum fulvous ; elytra finely and closely punctured, the base of each with a regular black ring-shaped mark, another semilunate similar mark, open at its posterior portion, placed near the apex. San Esteban. Closely allied to D. ineequalis, D. haroldi, Baly, and D. biannu-laris, but differing from all these species in the fulvous head and legs ; from D. delineata, Jac, a still more closely allied species, the present insect may be separated by the much longer antennae, which have their joints (with the exception of the second and third) much more elongate and also differently coloured, and by the elytral broader markings which in D. delineata are very thin and fine. DIABROTICA OBSCURO-MACULATA, n. sp. Subdepressed, obscure testaceous ; antennae long, the third joint elongate ; thorax finely punctured, transversely depressed ; elytra closely punctured, the interstices subrugose, the suture anteriorly, |
