( 321 ) XXIX. Descriptions of neto species of Hemiptera-Homoptera. By W. L. Distant. [Read Novemlier Gth, 1878.] My friend, Mr. F, Moore, having submitted his fine col-lection of Indian Honioptera to me for identification, I found, in addition to many rare insects, the three follow-ing new species of Cercopidce. I have also added diag-noses of some other undescribed Homopterous forms from the collections of Mr. F. J. Horniman and my own. Fam. CERCOPID.F:. Genus CosMOSCARTA, Stal. Cosmoscarta horealis, n. sp. Pilose. Head and pronotum luteous ; antennas black ; abdomen and tegmina roseate ; ocelli black, placed much nearer to each other than they are from eyes. Face tumid, much compressed, transversely strigose, and deeply and broadly sulcated in front. Eyes prominent, luteous, thickly covered with irregular blackish markings. Pro-notum deflexed towai'ds head, on which portion is a raised central longitudinal line, and an irregular fovea behind eyes (much more distinct in some specimens than in others); Avings pale fuscous. Pectus, coxre and femora luteous, fore and intermediate tibias black, hind tibifB luteous with apex black. Apex of rostrum, tarsi and strong, spine near apex of posterior, tibite black. Long. ex. tegm. 6 mill; exp. tegm. 17 mill. Khasia Hills ; W. Yunnan. Coll. Moore ; Distant. Allied to the Bornean species C. semirosea, Walk., from which, in addition to other characters, it can be at once distinguished by the colour of the prouotum and fore and intermediate tibiae. Cosmoscarta Moorei, n. sp. Black, shining, irregularly pilose. Tegmina thickly and finely punctured, with the base, both above and below, carmine. This coloration consists of a narrow straight subcostal streak of about 3 mill, in length, and a bi'oader TRANS. ENT. SOC. 1878. — PART IV. (dEC.)
