Show 624 MR. MARTIN JACOBY ON NEW [Nov. 6, entirely impunctate, black, opaque, all the margins narrowly flavous, the sides but narrowly flattened; scutellum black; elytra without any punctuation, of exactly similar coloration as the thorax ; underside and legs black. Hab. Rio Grande do Sul, Brazil. This species will be easily known by the sombre coloration, the proportionally long thorax, and the entire absence of any sculpturing. EPIONYCHIS FASCIATICOLLIS (Clk. Catal.). (Plate XXXVIII. fig. 5.) Black or piceous ; thorax fulvous, with a transverse black band, impunctate : elytra flavous, a transverse band at the base, angulate at the shoulders, another broader band below the middle, widened at the suture, and a spot at the apex black or fulvous. Length 3 lines. Head with a few fine punctures between the eyes, black, rather flattened, the frontal elevations obsolete, carina short and thick; antennae extending to the base of the elytra, black, the basal three joints dark fulvous, third joint slightly longer than the second but a little shorter than the fourth joint; thorax with the anterior and posterior margins rounded, parallel, the sides strongly rounded, the anterior angles slightly produced outwards, the surface impunctate, fulvous with a black transverse band, not extending to the sides, the edges of this band irregularly notched; scutellum black : elytra wider at the base than the thorax, widened at the middle, finely and closely punctured, flavous, with a narrow transverse black band at the base which turns dowmvards at the shoulders to about one third the length of the elytra, but does not extend to the lateral margin; another broader band is placed below the middle, this band extends quite to the sides, widens at the suture, and has the anterior and posterior margins deeply sinuate or dentate, it is connected by the suture with a small spot at the extreme apex : underside and legs black. Hab. St. Paulo, Brazil, also Bolivia. The band at the thorax is in some specimens divided into two spots, and the elytral bands may be of bluish-black or fulvous colour; their shape and position will help to distinguish the present species from others having transverse bands. EPIONYCHIS BRUNNEOFASCTATA, u. sp. (Plate XXXVHI. fig. 8.) Below fulvous, above testaceous, head fulvous; thorax scarcely perceptibly punctured, testaceous ; elytra very finely and closely punctured, testaceous, two elongate spots at the base and a transverse band at the middle, not extending to the sutural or lateral margin, pale brown. Length 4 lines. Head fulvous, shining, with a few punctures near the eyes and a deep transverse groove between the latter, frontal tubercles transverse, strongly raised, carina and clypeus also strongly swollen |
