Show 132 MR. W. L. DISTANT ON UNDESCRIBED CICADID^L. [Jan. 17, the head, including eyes, is considerably narrower than base of pronotum ; anterior femora armed with three strong spines. Long. 16 millim. ; exp. tegm. 45 millim. Hab. Australia, Sydney. (Coll. Dist.) This species was identified by Walker (List Horn. i. p. 172. 117, 1850) as the Cicada melanopygia, Germ., and thus stands in the collection of the British Museum. Germar's species, however, belongs to the genus Tibicen, and as such has been fully described by Stal (Ann. Soc. Ent. Fr. ser. 4, vol. 1, p. 618. 2, 1861.) MELAMPSALTA LEICHARDTI, n. sp. (Plate VII. figs. 5, 5a, 56.) 5 . Body above ochraceous. Head with the frontal anterior margin, a spot on anterior lateral angles of vertex, an oblique fascia behind eyes, two small linear spots between ocelli and eyes, a transverse spot on anterior margin of vertex, and antennas black. Pronotum with two central linear black lines, not extending to posterior margin, and widened and angulated near anterior margin, oblique striae, and inner border of posterior margin (on centre of which is a round spot) black. Mesonotum with two short contiguous central obconical spots, on each side of which is a more elongate and broken one, and two small rounded spots in front of basal cruciform elevation, black. Abdomen with a series of dorsal transverse black fasciae, decreasing in width towards apex. Anal appendage with a black line on each side. Body beneath ochraceous; base and lateral margins of face, apex of rostrum, and ovipositor black. Legs ochraceous; femora streaked with fuscous; anterior tibiae black, annulated with ochraceous near base. Tegmina and wings pale hyaline ; tegmina with the costal membrane and area and veins enclosing basal ulnar area pale ochraceous, remaining venation fuscous. Head, including eyes, equal in width to pronotum ; rostrum reaching intermediate coxae; face somewhat compressed, centrally and longitudinally broadly sulcated for half its length, and transversely striate. Long. 10 millim. ; exp. tegm. 25 millim. Hab. Australia, Peak Downs. This small but distinct species is allied to 31. sericevitta, Walk.; and I am indebted to M r . Pascoe for an opportunity of comparing tbe same. The figure here given is considerably enlarged. CYSTOSOMA SCHMELTZI, n. sp. (Plate VII. figs. 11, 1 la, 116.) Closely allied to the only other known species of the genus, C. saundersii, from which it differs in being only one third the size, and principally in the very different venation of the tegmina, the reticulations of which are faithfully portrayed in the figure, and cannot be adequately described, but are different in pattern and less extended in area than in the other species. The abdomen is much - smaller and less inflated; the opercula are obscurely sinuated on their lateral and posterior margins. Long. 25 millim.; exp. tegm. 62 millim. Hab. Australia, Gayndah. (Mus. Godeffroy.) |
