Show 1903.] SOUTH-AMERICAN COLEOPTERA. 57 and irregularly punctured at the flavous portion, the dark markings also surrounded or bounded by deeper punctures, the suture, to the extent of the second row of punctures, black, in shape of a narrow, anteriorly widened stripe which does not quite extend to the base; of the dark markings three short longitudinal slightly curved stripes are placed at the base, of which the inner two are joined at the apex, these stripes do not extend to the basal margin but the inner ones nearly reach the middle, they are followed by a crescent-shaped narrow band at the sides, within which a smaller nearly ring-shaped mark is placed, near the apex another V-shaped spot is situated, at the middle of the lateral margins there is another smaller black spot, and the elytral epipleura? are of the same colour ; the abdomen and the legs are fulvous ; claws united at the base. Hab. Costa Rica. (In m y collection and that of the British Museum.) The peculiar elytral markings differ from those of any other species of the genus ; the flavous ground-colour has a golden hue, which is probably more brilliant in the living insect. ZYGOGRAMMA BRASILIEXSIS, sp. nov. Reddish fulvous ; thorax strongly punctured at the sides, minutely at the disc; elytra finely punctate-striate, black, the third, fifth, and the ninth and tenth interstices, as well as the epipleura?, flavous, the two inner flavous stripes connected at the apex. Length 6 millim. Closely allied to Z. flavolorata Stal and Z. myops Stal, and to a few other species with flavous elytral stripes and epipleura?, but at once distinguished from them by the fulvous head, thorax, and legs ; the head impunctate ; antennae short, fulvous, the apical five joints black, strongly transverse ; thorax strongly transverse, closely and strongly punctured at the sides, fulvous, the basal margin sometimes piceous; scutellum black; elytra finely and regularly punctate-striate, the basal margin and three narrow longitudinal stripes flavous, the discoidal ones joined near the apex, occupying the third and fifth interstices, the outer stripe with a row of punctures, the extreme lateral margins black, the epipleura? flavous. Hab. Espirito Santo, Brazil. Three exactly similar specimens are contained in m y collection. ZYGOGRAMMA BURMEISTERI, sp. nov. Greenish black ; thorax narrowed anteriorly, strongly punctured at the sides ; elytra striate-punctate, the interstices slightly convex, the base of the first, the third and fifth entirely, and the tenth flavous. Length 7 millim. Head very minutely punctured ; antenna? with short, transverse terminal joints, broader than long, black, the basal two or three |
