All these characters are, however, not wanting in many species of Disonycha, and intermediate stages frequently occur in which it is impossible to say to which genus to refer the species. JVephrica is therefore not a well-founded genus, and it is impossible to fix the limit between this and Disonycha. Nevertheless I have left the question in its present state, and described all those species contained in m y collection in which the kidney-shaped eyes and other details peculiar to von Harold's genus are well marked, so that there will be little difficulty in recognizing these forms. NEPHRICA BOLIVIANA, sp. n. Pale flavous, the base of the head, the antennae, underside, and legs black ; thorax impunctate ; elytra extremely minutely punctured, yellowish white, a broad transverse band at the base and another below the middle, not extending to the lateral nor apical margins, metallic green. Length 6 millim. Head piceous at the base, impunctate, the lower portion nearly white, the carina distinct and broad; antennae not extending to the middle of the elytra, piceous, the basal joint flavous below ; thorax twice as broad as long, the sides very feebly rounded, with a narrow margin, the anterior angles truncate, the posterior slightly truncate, the surface impunctate, yellowish white ; scutellum black; elytra nearly impunctate or with some extremely minute punctures at the sides, metallic green, this colour not quite extending to the lateral nor apical margins, and divided at the middle by a narrow transverse flavous band; below and the legs black (in immature specimens stained with flavous). Hab. Bolivia. Allied to N. didyma Illig. and N. kirschi Har., but differing in the design and colour of the elytra. In the above given description I have taken the green colour for that of the ground, but in the diagnosis the pale colour. NEPHRICA MACULIPENNIS, sp. n. (Plate XX. fig. 8.) Below black, as well as the antennae and legs ; head and thorax flavous, the latter with five small black spots (4, 1); elytra closely punctured, testaceous, the basal margin, the shoulders, a narrow lateral stripe, connected with a broad transverse band below the middle, and a round spot near the latter part, metallic green. Length 7 millim. Head sparingly punctured near the eyes, flavous, the extreme vertex black ; carina acute, labrum and palpi black; antennae short, not extending to the middle of the elytra, black, the lower three joints testaceous below, third joint shorter than the fourth, terminal joints slightly thickened; thorax twice as broad as long, the sides feebly rounded, the anterior angles oblique, the surface impunctate, flavous, with four small piceous spots placed transversely anteriorly, and another spot at the middle near the base |
