Fh. obscuratus Hmps. Body and wings pale ochreous-yellow, strewn with brown, abdomen above 
more brown. The forewings exhibit in the lower cell-angle a black dot, behind it a faded, dark brown band 
which is broken in the shape of an acute angle behind the lower cell-angle, and before the apex a hazy, brown 
oblique spot. Hindwing towards the base diaphanous. Expanse of wings: 40 mm. Colombia. 
Ph. perirroratus limps. Ochreous, densely strewn with blackish. Abdomen above almost entirely 
blackish. Forewings very densely and uniformly watered brown. Hindwings semi-cliaphanous, at the border 
more densely dusted and clouded brownish-black. Expanse of wings: 46 mm. Bolivia. 
157. Genus: Hyaleucerea Btlr. 
It strikingly approximates Eucereon from which it chiefly differs only by the two uppermost subcostal 
veins rising freely from the cell. The wings are long and narrow, the costal margin towards the apex strongly 
bent with a rather sharp point. 
H. vulnerata Btlr. (= myrrhine Burm.) (26 i). The body is black, the abdomen curled red; large spots 
on the collar and shoulder-covers are white. The forewings are brown with black markings, large hyaline spots 
in the disc and behind the cell, and a small white apical spot. The hindwings are hyaline with a black border. 
Distributed from Mexico to Argentina. — boliviana subsp. nov. A number of specimens from the Rio Songo 
in Bolivia (Fassl) invariably have the two last abdominal rings above coloured all red. 
H. phaeosoma Hmps. (— minuta Bothsch.) (31 1). Head and thorax olive-brown, mixed with blackish- 
brown; neck carmine; palpal base yellow-white. Abdomen blackish-brown with a blue lustre, beneath white. 
Forewings blackish-brown, on the veins and in the cell striped olive-yellow, also an antemedian costal spot 
is olive; at the cell-end, behind it and below it, hyaline spots; an undulate antemarginal line and an apical 
spot are olive. Hindwings hyaline with black veins and a broad bluish-black border. / Expanse of- wings: 30 mm. 
Paraguay. 
H. luctuosa Mschlr. is brownish-black, suffused with a dull bluish-green, on the body with a somewhat 
brighter metallic blue and green; the abdomen exhibits besides lateral and sublateral rows of metallic green 
spots. Hindwing with a large, hyaline discal spot extending almost to the margin. Expanse of wings: 40 mm. 
Surinam. 
H. morosa Schs. (31 k). Body dull greyish-black, abdomen towards the end deep bluish-black; hind- 
head and on each side a spot below the eye dark red. Forewings greyish-black, the veins, a stripe in the cell 
and one below it, a broad median shade from the cell to the proximal margin, and an antemarginal shade black; 
at the base of the proximal margin there is a small, dark blue spot. Hindwing bluish-black with a diaphanous 
stripe, in and below the cell. Expanse of wings: 43 mm. Costa Rica. 
H. erythrotela Wlcr. (26 i). Black; neck and apex of abdomen carmine. Wings hyaline with a broad 
black border and a discal spot cohering with the distal margin. Honduras; Venezuela; Guiana; Para. 
H. chapmani Klages. Body brownish-black; abdomen, beginning from the 4th ring, with lateral red 
spots. Wings hyaline, with broad, blackish-brown veins and margins and a large discal spot. Expanse of wings: 
26 mm. Venezuela. The species is better placed to the genus Pezaptera (p. 113). 
H. fusiformis Wlcr. (= trifasciata Btlr.) (26 b). Black; vertex, collar and neck laterally spotted 
carmine; front of palpi, forehead, shoulders, chest, forehips, and femora spotted white; the abdomen on the 
ventral side with two rows of white spots. Forewings black, thinly scaled; hindwings hyaline with a black 
border. From French Guiana to the Amazon. 
H. leucoprocta Dogn. (26 b) is one of the largest species with a sooty black body, being very 
conspicuous by the 4 last abdominal rings being coloured yellowish-white above; besides, the abdomen shows 
a white lateral line. The wings are sooty black with deeper black veins, cellular and submedian folds. The 
entirely black hindwings show in the cell a lighter streak. French Guiana. 
H. leucosticta Druce (31 1) is likewise black; the abdomen exhibits a white dorsal spot only on the 
last segment; vertex, pro- and metathorax spotted white; lateral stripes on the abdomen white. Forewings 
similar as in the preceding, but with distinct darkenings at the costal margin, near the proximal angle and at 
the apex. The hyaline hindwings are bordered with black. Venezuela, French Guiana. 
H. lugubris Schaus is quite unicolorously sooty black, on the forewings in the interspaces somewhat 
more thinly scaled, with darkenings at the proximal margin, costal margin and cell-end; hindwing semi-dia¬ 
phanous in the disc. Colombia, French Guiana. 
H. uniformis Bothsch. (31 1) is monotonously sooty brown-grey, veins, hindwings and abdomen darker, 
more black. The hindwings are towards the base lighter, diaphanous. Length of forewings: 23 mm. South 
Brazil (Sa. Catharina).
