Primaries black, crossed beyond the middle by two small hyaline bauds, neither of which reaches the margin of the wing; a small hyaline streak extends from the base as far as the end of the cell. Secondaries whitish hyaline, broadly bordered with black at the apex, outer and inner margins. Underside very similar to the upperside, but the inner margin of the secondaries broadly bordered with greyish white. Head, antennae, thorax, abdomen, and legs black; the underside of the abdomen white. Hab. Ecuador, Chiguinda (Buckleg, Mus. B.). This species is quite unlike any known to me. MONOCREAGRA, Feld. MONOCREAGRA ORTHYADES, sp. n. (Plate X X . fig. 7.) Primaries and secondaries dusky hyaline; the veins of both wings black. The costal margin, apex, and outer margin of the primaries bordered with black ; the secondaries the same. Underside similar to the upperside. Head, antennae, palpi, thorax, abdomen, and legs black; the underside of the abdomen greyish brown. Expanse If inch. Hab. Ecuador, Intaj (Buckley, Mus. B.). Allied to M. pheloides, Feld., from which it is at once distinguished by the entire absence of the white band on the primaries. MONOCREAGRA (?) CHARES, sp. n. (Plate XX. fig. 8.) Primaries and secondaries hyaline; the veins dark brown. Primaries crossed at tbe end of the cell by a brown band, beyond which a wide orange-yellow band crosses the wing from the costal to the outer margin, almost reaching the anal angle. Secondaries with the outer margin shaded with orange-yellow; the fringes brown. Underside very similar to the upperside. Antennae black; the head, thorax, abdomen, and legs dark brown; the underside of the abdomen brownish white. Expanse 2 inches. Hab. Ecuador, Sarayacu (Buckley, Mus. B.). A fine species, exceedingly distinct from any other known to me. MONOCREAGRA (?) CHORAX, sp. n. (Plate X X . fig. 9.) Male.
