EXOTIC MICRO L EPIEOP TEE A. 
tornus chestnut-brown, enclosing a costal blotch of light ochreous 
suffusion, and some white suffusion at apex, a white dot in middle 
of edge of this patch representing second diseal stigma : cilia light 
brownish. Hindwings 3 and 4 connate, 6 and 7 stalked; ochreous- 
white; a grey fascia on upper | of termen, moderately broad at 
apex and diminishing to a point downwards ; cilia whitish, on 
fascia suffused light grey. 
Colombia, Mt. ISocorro, 12,500 feet, duly; 1 ex. Strongly re¬ 
sembles a Peronea such as varieganci , and quite unlike any other 
Stenomci. 
Stenoma notosaris Heyr. 
Hindwings with greyish-ochreous hairpencil enclosed in sub¬ 
dorsal groove (omitted in description). 
COPROMORPHID2E. 
NEOPHYLARCKA, n. g. 
Head with loosely appressed hairs, sidetufts somewhat raised; 
ocelli posterior ; tongue developed. Antennas somewhat over 4, 
in <$ rather stout, shortly ciliated, basal joint short, without 
pecten. Labial palpi moderate, subascending, not reaching base of 
antennae, stout, thickened with appressed scales, terminal joint 
hardly half second, obtuse. Maxillary palpi obsolete. Postejior 
tibiae with appressed scales. Forewings 1 b simple (absolutely), 
2 from |, 3-5 approximated at base, 4 from angle, 7 and 8 rather 
short-stalked, 7 to apex (indefinite), 11 from middle. Hindwings 1, 
trapezoidal-ovate, cilia \; with subcubital pecten (just beneath 
cubital vein but not on it); 2 from |, 3 from angle, 4 approxi¬ 
mated, 5 nearly parallel to 4, median vein well-maiked, branches 
running to 5 and 6, transverse vein wholly absent between these, 
otherwise well-marked, (5 and 7 approximated at base but distinctly 
separate, 8 running evenly near upper margin of cell and basal 
portion of 7 but not touching or connected, to costa at §; frenulum 
in cf with apical extremity much thickened and bent up at right 
angles, in $ of two bristles, upper slightly thickened at apex and 
bent up as in <S . 
The frenulum is unique in the Lepidopterci , so far as I know, 
but the next genus gives the intermediate form between this and 
the normal type. 
Neophylarcha helicosema, n. sp. 
c? 2 • 15-17 mm. Head, palpi, thorax whitish-ochreous. Fore¬ 
wings elongate, rather dilated, costa moderately arched, apex 
rounded-obtuse, termen rounded, vertical; whitish-ochreous, poste¬ 
riorly tinged brownish-ochreous with some fuscous speckling; 
short blackish-grey marks from costa and dorsum at base ; an 
oblique blackish-grey shade from costa at 1 reaching half across 
wing, and a white spot emitting a short zigzag streak margined on 
each side blackish-grey from costa at 1, space between these and
