Show 1878.] HEMIPTERA OF ST. HELENA. 471 et refiexo preecipue ad basin, margine interiore pone apicem recto, margini elytri alterius haud incumbente; (membrana desunt;) pedibus modicis, tibiis ad apicem subincrassatis; articulo 1° brevi, articulo ultimo longissimo. d 2 • Long 3-5, lat. (pone medium) 2-3 m. m. Hab. in editioribus insulae, juxta "Diana's Peak." The absence of the membrane prevents me referring this to any of the sections given by Dr. Stal in his ' Enumeratio.' It may perhaps belong to a new genus ; but as it has all the facies of a Salda, I have placed it in that genus. S. aberrans is very variable in the intensity of the brown markings. Frequently the corium is more or less of a rich fulvous brown with anastomosing black lines ; the whitish spots also vary in intensity. There is, moreover, a considerable range of variation in the size of the animal. 20. ISSUS COLEOPTRATUS, F. Hab. intermedis insulae, ad "Plantation." A common European species, and doubtless introduced into St. Helena. LIBURNIA, Stal. ILBURNIA, subgen. nov. Antennarum articufus primus articulo secundo cequilongus vel longior. Tibia postica tarso postico parle quarto longior. 21. LIBURNIA (ILBURNIA) IGNOBILIS, sp. n. L. testaceo-brunnea ; fronte distincte, clypeo, pronoto scutelloque obsolete (carinis exceptis), sterni maculis nonnullis abdomineque plus minus brunneis; dorso abdominis utrinque vitta longitu-dinali pallida, in segmentis 1° ad apicem, 2° et 3° ad basin et in segmentis 1°, 4° , 5°, 6°que interne magis, minus brunneo-marginata; connexivo brunneo, angulis exterioribus apicalibus pallidis; tarsorum unguiculis piceo-nigris; subhyalinis, concoloribus,vix dimidium abdominis tegentibus; subrufis ; capite desuper viso et pronoto longitudine subcequalibus, Mo inter oculos breviter prominulo, vertice singulo oculo ; carinis omnibus discretis ; fronte longa, deorsum dilatata, carina centrali ad verticem brevissime furcata; clypei centrali obsoleta; pronoto scutelloque distinctissime illius carinis lateralibus obliquis rectis marginem posticum alis abbreviatis. 2 . Long. 5, lat. 2 m. m. Habitat in excelsioribus insulae, ad " Diana's Peak." Ilburnia diverges from the characters of Liburnia by the longer first joint of the antennae, and the shorter hind tarsus. In the collection are two other Homoptera belonging to this family: one, which is much broken, is perhaps the <f of the above ; and the other seems to be an immature Stiroma ? |
