Show 554 MR. M. JACOBY ON T H E [May 18, legs fulvous; the posterior femora black, prosternum finely punctured. Hab. Mashonaland (67. Marshall). I have taken rather arbitrarily the form with black elytra and two fulvous spots for the type, but the species seems subject to great variation in regard to colour. In the typical form each elytron has a subtransverse large red spot placed in the middle; in the variety a the red colour is so increased as to reduce the black portion to a transverse narrow band at the base and a small sutural spot at the apex, until in the variety 6 this also disappears and the elytra are entirely reddish fulvous; the posterior femora remain, however, constantly black. EHYLLOTRETA MASHONANA, n. sp. Elongate, black, shining, the basal joints of the antennae and the base and apex of the tibiae fulvous ; thorax finely, elytra very closely and more strongly punctured. Mas. The fourth and fifth joints of the antennae dilated. Length 1 line. Head finely rugose-punctate, with a short central groove between the antennae, the carina, and the clypeus in shape of acute ridges; labrum black; antennae scarcely extending to the middle of the elytra, black, the lower three joints fulvous, the basal joint black above, second and third joints short, equal, fourth thickened, moniliform, fifth similarly thickened but twice s long as broad, subquadrate, the rest subequal, rather short; thorax one-half broader than long, the sides rounded, the anterior angles slightly oblique and thickened, the surface closely and finely punctured; elytra subdepressed, rather more strongly punctured than the thorax, the punctures extremely closely and irregularly placed, the interstices here and there slightly wrinkled : underside and legs black, the base and the apex of the tibias, as well as the tarsi, fulvous; prosternum narrow ly elongate; mesosternum twice as long as broad. Hah. Mashonaland (67. Marshall). British Museum and my collection. PHYLLOTRETA OPACA, n. sp. Black, opaque, the basal joints of the antennae and the tibias and tarsi flavous ; thorax finely, elytra more strongly and closely punctured. Length |-| line. M u c h smaller than P. mashonana and opaque, not shining, the head extremely finely and rather sparingly punctured, without any frontal tubercles ; antennae scarcely extending to the middle of the elytra, black, the lower three or four joints flavous, the basal joint-elongate, not thickened, the second one slightly longer than the third (J ?), equal in the female, terminal joint not thickened or slightly so, elongate ; thorax about one-half broader than long, the sides straight, the anterior angles oblique, the disc rather deflexed, |
