Druce, H. (1911). Descriptions of some new species of Heterocera from tropical
South America, and two new species of Geometridae from West Africa. Annals and
Magazine of Natural History (8) 7: 287-294; p. 288 (as Pericopis practides).

Male. Head, antennae, palpi, collar, tegulae, thorax, abdomen, and legs black,
the tegulae tipped with yellow, the sides of the abdomen spotted with white, the
underside of the abdomen with a double row of yellow spots; the anal tuft red.
Primaries blackish brown, shaded with semihyaline grey at the end of the cell
and beyond the cell to the inner margin; the inner margin edged with
chrome-yellow, extending from the base to the anal angle; a marginal row of
small white dots extends from the apex to the anal angle; a red spot at the
base of the wing: secondaries semihyaline white, clouded with blackish brown,
the veins black; the costal and outer margin broadly bordered with
chrome-yellow, edged with black on both sides; a series of white points extends
from the apex to the anal angle. Underside very similar to the upperside,
except that the outer margin of the primaries is broadly bordered with
chrome-yellow almost to the apex. Female very similar to the male, but browner
and the marking more indistinct; the submarginal greyish-white line much more
distinct; the abdomen banded with white.
Expanse, male 2 1/2, female 3 inches.
Hab. Colombia, Paso del Quindin, 3600 m. (Mus. Druce).
Allied to Pericopis arema, Boisd., and Pericopis palmeri, Druce.

P. practides Drc. (63 e). Body black, patagia spotted yellow, abdomen above
with subdorsal rows of white spots, beneath with two rows of yellow spots.
Forewing blackish-brown, proximal margin with an ochreous-yellow margin. Across
the cell-end extends a grey hyaline band to the proximal margin, enclosing the
brown cell-end spot; white submarginal spots. Hindwing whitish hyaline, clouded
with blackish, veins black, transverse vein broad-black, costal and distal
margins ochreous-yellow, on both sides narrowly edged with black, white
marginal spots. Forewing beneath more extensively ochreous-yellow. Female with
more indistinct markings, abdomen with white bands. Colombia.

Redescription. Male (Fig. 30 E).
Head: brown, vertex brown. Labial palpus brown.
Thorax: predominantly brown. Prothoracic collar brown. Tegula with a yellow
spot in the basal region near the outer margin. Fore wing with costal and outer
margins brown, inner margin yellow; a greyish semi-hyaline patch occupying
almost the whole basal and median region, the distal edge of the patch picked
out by white scales; a subquadrate brown spot at the closure of the discal
cell; submarginal band formed by white dots between R3 and 1A+2A, obscured in
some individuals; wing base with two sets of scale tufts, pinkish on the stem
of R and beige on the stem of CuA; underside with a pattern like the upperside,
but the region between the semi-hyaline patch and the submarginal band ochre,
most evident near the tornus, and the wing base with a pinkish spot in the
costal region. Hind wing predominantly hyaline, costal and outer margins brown,
veins outlined by light brown scales; a brown spot at the closure of the discal
cell; submarginal band with its proximal element formed by yellow half-moon
spots between Sc+R1 and 2A and its distal element formed by white triangular
spots between Sc+R1 and 1A; underside with a pattern like the upperside, but
the wing base with a pinkish spot in the costal region.
Abdomen: dorsally dark brown, with two lateral bands formed by white spots on
segments A3-A7, obscured in some individuals; ventrally dark brown with two
lateral bands formed by yellow spots on segments A3-A7. Terminal part of the
abdomen with a tuft of pinkish scales.
Genitalia (Fig. 63): tegumen rectangular in dorsal view, anterior margin
straight, postero-lateral projections absent. Uncus bifid, not fused to the
tegumen; arms of the uncus divergent, fused in their anterior part, not
projected ventrally. Valva entire; medial apodeme (lacinia) absent, distal
apodeme absent; sacculus distinct, in the form of a fold; harpe distinct,
rectangular and narrow; cucullus digitiform, apex acute, as long as the
valvula, directed towards the medial region; valvula membranous, triangular.
Transtilla sclerotized, not articulated with the valva or the juxta. Juxta
sclerotized, two sclerites partly fused dorsally, cordiform. Saccus with an
anterior, central, subtriangular projection. Aedeagus straight, smooth;
ejaculatory bulb rounded, foramen lateral; caecum digitiform, vesica with a
lobe ornamented with microspicules, everted part of the ejaculatory duct
smooth.
Female (Fig. 30 F).
Head: like that of the male. Thorax: like that of the male. Abdomen: like that
of the male.
Genitalia: seventh sternite smooth; ostium membranous, not fused to the
sternite, without projections; antrum membranous; ductus bursae membranous,
short, straight; corpus bursae not extending beyond the seventh sternite, signa
absent. Lamella antevaginalis absent; lamella postvaginalis absent.
