Show 1889.] COLLECTED IN VENEZUELA. 281 as the body, entirely dark fulvous, the second and third joints short, equal, the fourth joint longer than the two preceding united ; thorax quadrate, slightly narrowed at the base, smooth, shining, green, the disk bifoveolate ; scutellum black; elytra closely and finely rugosely punctured, the base, the extreme lateral margin, and the suture narrowly pale flavous, the anterior portion of the suture below the scutellum with a short black stripe ; at and below the middle a very obscure flavous transverse spot is seen which in the variety is absent; the abdomen and the femora pale green, the tibiae, tarsi, and the breast black. Colonia Tovar. The two sexes of this species were taken in copula ; the female, which is slightly larger than the male, has four more or less distinct piceous spots placed transversely on the thorax; the shoulders have also a reddish-fulvous spot. The entirely fulvous antennae and the differently marked elytra separate D. simoni from D. mutabilis, D. gemmingeri, Baly, and other allied species, the smaller size and the want of the black lateral vitta of the elytra, as well as the green abdomen, from J), virginella, Baly. DIABROTICA FULVOFASCIATA, n. sp. Pale flavous ; head, antennae, and thorax obscure fulvous ; elytra pale greenish, with an obscure fulvous longitudinal band, finely and closely punctured. Male. Antennae very strongly thickened and widened at the intermediate joints. Length 2 | lines. Head pale fulvous, the vertex with a fovea; labrum piceous ; antennae extending to about half the length of the elytra, dark fulvous, the second and third joints very short and equal, the fifth to the ninth joints greatly dilated and thickened, the terminal one narrowly cylindrical with a short appendage ; thorax scarcely one half broader than long, narrowed at the base, obscure fulvous, the lateral margins narrowly greenish, the surface impunctate with two obscure longitudinal depressions ; scutellum piceous ; elytra closely punctured, with an obsolete, longitudinal depression at the sides and faint traces of longitudinal costae, pale greenish, the middle of the disk occupied by an obscure pale fulvous band from the base to the apex; femora pale greenish, the rest of the underside and legs flavous. Caracas. The single male specimen contained in this collection agrees nearly in coloration with D. porracea, Har., and several other allied species, but is distinguished by the strongly dilated antennae and the paler general colour; the former character is also found in D. mutabilis, Baly, but this species differs totally in colour. DIABROTICA ESTEBANENSIS, n. sp. Black ; the basal and the two penultimate joints of the antenna?, as well as the femora below, flavous; head and thorax fulvous, the |
