Show 1905.] OF PHYTOPHAGOUS COLEOPTERA. 437 dividing space; labrum fulvous; antennae with the lower four and the apical three joints fulvous, the others black, third and following joints nearly equal, elongate; thorax with strongly rounded and flattened sides, the anterior angles mucronate and produced forward, the disc impunctate, testaceous, obsoletely transversely grooved near the base ; elytra finely and closely punctured, rather flattened, narrowly marginate, each elytron with two narrow longitudinal stripes-one near the suture, the other near the lateral margins, below the middle both, or one, of the stripes are interrupted, so that only one or two elongate spots remain near the apex ; under side and legs testaceous, the breast black. Hab. St. Catharina, Brazil. In one of the specimens the inner black elytral stripe only is interrupted; in the other this is the case with both stripes, there is also an indication of another stripe in shape of a minute spot between the others, placed at the middle. Amongst the species with elytral longitudinal bands the present one is well distinguished by the colour of the head, antennae, and the shape of the elytral stripes, which resemble signs of exclamation. Elytra pale, ivith transverse black or blue bands or spots. O e d io n y ch is b is t r if a sc ia t a , sp. n. Black or piceous, antennae dark fulvous, clypeus flavous ; thorax impunctate, flavous; elytra finely and closely punctured, flavous, each with three transverse dark blue bands, the first subquadrate and emarginate or subdivided at the base. Length 5| millim. Of rather elongate shape ; the head bluish black, with some strong punctures near the eyes; clypeus and labrum flavous, the eyes likewise margined more or less with the same colour ; antennae extending to nearly the middle of the elytra, dark fulvous, the basal two joints more or less stained with black above, third and fourth joints equal, terminal joints slightly thickened ; thorax rather more than twice as broad as long, the sides strongly but not very broadly flattened, the lateral margins rounded anteriorly, anterior angles produced into a short blunt tooth, the surface impunctate or with a few very minute punctures, obsoletely transversely grooved near the base, flavous; scutellum black; elytra finely and closely but distinctly punctured, with three transverse blue or purplish bands-the first at the base the largest, of subquadrate shape, its basal margin with a narrow incision, the second band immediately below the middle, half the width of the first band, the third near the apex, short and of subquadrate shape, none of these bands extends to either margin ; below and the legs black or piceous. Hab. Peru. In one of the specimens before me the basal band is also rather deeply emarginate near the suture at the sides as well as at the base. |
