Dorsal segments, excepting the first, palish chestnut, spotted and blotched with pitchy; head, nuchal plate, and first segment dark chestnut, more or less varied with black ; eyes pale greenish. Head shining, densely but finely punctured in front; nuchal plate with anterior ridge and row of ill-defined punctures; folded anterior ridge of first dorsal segment unusually thick, lateral wing broad, with feebly developed ridge ; dorsal segments for the most part smooth and polished, but with their front edge and anterior half of lateral wings somewhat rugose ; anterior half of last segment finely and densely punctured. Length 2 inches, width 1 inch. Hab. unknown. Coll. Banks in B.M. Allied to Z. sulcatula and Z. zebraica. 19. ZEPHRONIA VERSICOLOR. Zephronia versicolor, White, Ann. & Mag. Nat. Hist. ser. 3, vol. iii. p. 405. n. 3, pl. 7. f. 3, 3a, 36 (1859) ; Humbert, Myr. de Ceylan, in Mem. de la Soc. Phys. et d'Hist. Nat. de Geneve, xviii. pt. 1, p. 41, pl.3.f. 17(1865). Peradenia, Ceylon (Thwaites). Three specimens. Type, B.M. Group 6a. Head and nuchal plate hairy. 20. ZEPHRONIA LEOPARDINA. (Plate XIX. fig. 10.) Zephronia leopardina, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. x. p. 356. n. 5(1872). Ceylon (R. Templeton). Type, B.M. M y observation respecting the hairiness of this Zephronia was to some extent erroneous, the real hairs being confined to the head and nuchal plate. A microscopical examination of the dorsal segments shows them to be to all appearance merely dirty. Group bb. All the body hairy. 21. ZEPHRONIA CASTANEA. Zephronia castanea, Newport, Ann. & Mag. Nat. Hist. ser. 1, vol. xiii. p. 265(1844). Philippine Islands (Cuming). Type, B.M. Group be.

Hist. ser. 4, vol. x. p. 357. n. 12, pl. 18. f. 8 (1872). Philippine Islands (Cuming). Type, B.M.
