Show 530 MR. H. DRUCE ON NEW HETEROCERA. [May 19, MENNIS, Walker. M E N N I S FIDENTIA, sp. n. (Plate XXXIII. fig. 1.) Primaries brick-red, with the apical third of the wing sooty black : secondaries brick-red, bordered with black from the apex to the anal angle; the underside the same as above. Head, thorax, and abdomen black ; antennae, palpi, and legs brownish black. Expanse 1| inch. Hab. Colombia, Antioquia (Salmon). A well-marked and very distinct little species, not nearly allied to any with which I am acquainted. MENNIS HERONA, sp. n. (Plate XXXIII. fig. 2.) Primaries from the base to the middle dull red, from the middle to the outer margin semihyaline smoky black : secondaries dull red, broadly banded with black at the apex, the outer and inner margin narrowly streaked with black. Head, thorax, and abdomen brownish black; the antennae and legs black. The underside the same as above in all respects. Expanse 1 inch. Hab. Ecuador, Sarayacu (Buckley). A pretty little insect allied to the preceding species, from which it is at once distinguished by its much more slender form and different position of the red markings. MENNIS FICULNEA, sp. n. (Plate XXXIII. fig. 3.) Primaries semihyaline, clouded with bright red from the base to beyond the middle, the apex and outer margin to the anal angle broadly bordered with semitransparent black ; from anal angle along the inner margin to near the base slightly clouded with greyish white: secondaries bright red, somewhat transparent, broadly bordered with black from the apex to the anal angle, where the border becomes quite narrow. Head, thorax, and abdomen greyish black; antennae black. Expanse 1| inch. Hab. Ecuador, Intaj (Buckley). This species is very distinct, but comes nearest M. fidentia. MENNIS HAGNO, sp. n. Primaries shape and form of M. ficulnea, but smaller and the red colour of a much more orange shade, the outer half of the wings being dove-colour instead of black ; the secondaries differ in the same way as the primaries, the dove-coloured borders being wider than in ficulnea. Head and thorax black ; tegulae red; abdomen black, banded with dove-colour ; antennae and legs black. Expanse \\ inch. Hab. Ecuador, Intaj (Buckley). This species is easily distinguished from its allies by the dove-coloured margins of the wings. |
