84 Mr. Adam White's Description XIII. Description of some Hemipterous Insects of the Sec-tion Heteroptera. By Adam White, Esq., M.E.S. As-sistant in the Zoological Department of the British Museum. [Read 3 December, 1838.] Fam. SCUTELLERIDiE, Leach. Scutati p. Burm. Augocoris olivaceus. A. nitidissimus, fusco-olivaceus, maciilis sejjtem ccerulescenti-nigris thorace antice, scutello macula magna, basalt, miniaceis. Hab. in America meridionali (Buenos Ayres). I am indebted to Edward Newman, Esq. F.L.S. for an oppor-tunity of describing this fine species, as well as Callidea bifasciata, noticed below. The next species I shall describe is the ^ Tectocoris (Pcecilochroma*) Childrem. White, in Charleswortli's Mag. of Nat. Hist. Nov. 1839, p. 542. (Plate VII. fig. 1). T, luteo-fulvus ; thorace antice maculisque 4, [scutello maculis 1 1 , atris ; subtus nigrescenti-purpureus ; pedibus viridibus. Long. Sg lin., lat. tho. 5J lin. Hab. in Nepalia. In Mus. Brit. Head (including eyes, antennae and beak) black, distinctly mar-gined, ocelli yellow. Thorax yellowish fulvous, in front black, the black colour extending in a narrow line along the slightly raised lateral margin ; with four transverse black spots, the two dorsal ones larger and rather square. Legs green. Scutellum obtuse, of same colour as thorax, with eleven black spots, three at the base, the central one triangular and largest, two behind these, four in the middle (the two inner largest), and two near the tip. Hemelytra black, somewhat shining. Body beneath purplish black, sides of abdomen with four transverse yellow lines, sometimes confluent at the base and forming a yellow patch, end of abdomen green. Note. — The scutellum in front of the third range of spots is depressed, but whether this be constant or accidental cannot be determined. • I would suggest the separation of this division from the group containing cyanipes and Ba»i/cs«, retaining Hahn's name, Tectocoris, for the latter, and giving the name of Poscilochroma to the genus of which Cimex Drurai was the first described species.
