Show 110 MR. M. JACOBY ON THE [Feb. 1, rightly referred the present species to Motschulsky's insect, the closed anterior coxal cavities of L. quadripustulatus, as well as of the following species, would suggest rather the genus Monolepta or Nadrana for their reception, since tbe type, Luperodes alboplayiatus, Motsch., has open coxal cavities. It must, however, be left for the future to decide with certainty the proper place of these eastern forms. LUPERODES PECTORALIS, sp. nov. Ovate, convex; testaceous ; the base of the head, antennse, and the breast black ; thorax transverse, impunctate ; elytra very finely punctured, testaceous, a narrow transverse band at the base and the extreme margins black. Length 2 lines. Head impunctate, the basal portion as well as the labrum and the palpi black, the rest testaceous. Antennse as long as the body, entirely black, the third joint very slightly longer than the second, both joints short. Thorax more than twice as broad as long, the sides straight, the posterior margin rounded ; surface impunctate, without depression. Scutellum black. Elytra extremely finely and closely punctured, testaceous, sometimes stained with fulvous near the apices, the sutural and lateral extreme margins as well as a narrow transverse band at the base black. Legs fulvous or testaceous, the tarsi obscure fuscous. Breast black ; abdomen testaceous. The first joint of the posterior tarsi half the length of the tibise. Dikoya. From L. basalis, Motsch., the present species differs iu the entirely black antennse and the similarly coloured elytral margins, also in the fulvous legs. The thorax is more transversely shaped than is usual in the species of this genus, but all other characters agree with Luperodes. LUPERODES FLAVICORNIS, sp. nov. Testaceous ; breast dark fulvous ; head and thorax impunctate ; elytra extremely finely and closely punctured, reddish fulvous, the base obscure piceous. Length 2 lines. Head impunctate, transversely grooved between the antennse; the latter slightly shorter than the body, entirely flavous, the second and third joints short, equal; the fourth as long or rather longer than the two preceding joints together. Thorax transverse, without depressions, rather more than twice as broad as long, the sides slightly, the posterior margin more strongly rounded, the angles not produced. Scutellum obscure testaceous. Elytra slightly widened posteriorly, dark fulvous, very minutely and closely punctured, the base with a narrow transverse obscure piceous band. Posterior tibise mucronate, their metatarsus longer than the three following joints together. Anterior coxal cavities closed. Tbe single specimen contained in this collection differs from L. basalis, Motsch., in the unicolorous antennas, in the differently |
