Show 56 MR. MARTIN JACOBY O N N E W [May 12, row of punctures, joined to the third row at the apex, the basal margin likewise flavous, the rest of the interstices finely punctured and transversely wrinkled; claws joined at the base, the third joint dentate at the apex. Hab. Brazil. I know of no other species of Zygogramma with flavous thoracic margins in which the elytra are so strongly punctured or the interstices finely so; the subsutural flavous stripe gradually approaches the suture towards the apex : in the variety the antenna? and legs are fulvous, and the femora are spotted with aeneous, but other differences I cannot find. The punctation of the thorax varies much in depth and number of punctures, and the elytral wrinkles are also more or less distinct in different specimens. ZYGOGRAMMA ARGENTINENSIS, sp. nov. Dark greenish, the antenna? black ; thorax minutely punctured, the sides more strongly so; elytra with three narrow fulvous vitta?, the discoidal ones joined at the apex, the marginal one with a row of punctures, the subsutural rows geminate. Length 9 millim. Larger than any of the species placed in this genus described by Stal, of an opaque greenish colour, the head minutely punctured, the terminal joint of the palpi larger than the preceding one; antenna? black, the basal two joints flavous below, terminal joints widened ; thorax very finely punctured, the sides more strongly so ; scutellum impunctate ; elytra, regularly punctate-striate, the subsutural row double (the first row consisting of a few punctures only), the third, fifth, and ninth interstices flavous, the discoidal bands joined at the apex, the fourth interstice rather wider than the others, the marginal flavous vitta with a row of piceous punctures, elytral epipleura? greenish ; claw-joint dentate, claws joined at the base. Hab. Salta, Argentine Republic The larger size, greenish coloration, and the wider fourth interstice separates this species from its allies; the flavous bands are, as usual, joined together by the similarly coloured flavous basal margin. There are three specimens before me. ZYGOGRAMMA CURVATO-LINEATA, sp. nov. Dark fulvous, the breast greenish aeneous; thorax finely and sparingly punctured ; elytra flavous with a metallic lustre, each elytron with the following black markings: three short stripes at the base, the inner two joined at the apex, a semicircular band below the middle, another one within the outer band, and a V-shaped mark near the apex ; legs fulvous. Length 8 millim. Head impunctate, fulvous; antennae with the terminal joints moderately thickened, longer than broad, entirely fulvous; thorax very sparingly and finely punctured at the base and sides, fulvous; scutellum black; elytra punctate-striate near the suture, finely |
