H. poltrona Schs. Head and thorax brownish ochreous, abdomen tan-coloured, forewing brownish poltrona. 
ochreous at the costal and inner margins, ochreous between them, indistinct transverse lines in the distal half, 
darker than the ground-colour, bordered paler inward. The lines form spots. Hindwing red-brown, somewhat 
rosy in the cell. 40 mm. Castro (Parana). 
H. dormita Schs. Head and thorax dark brown, abdomen light brown; forewing reddish brown, shaded dormita. 
grey at the basal half of the inner margin and within the exterior line, especially towards the costa; a dark 
oblique shadow from the subcostal base to the middle of the inner margin. Exterior line fine dark grey, shaded 
lighter grey and followed by a broad red-brown shadow. Greyish antemarginal spots between the veins. A 
few silvery spots surrounded by black: one at the base of the cell, a larger oblique one at the cell-end, a 
few tiny spots at veins 5 and 6 beyond the exterior line, and at vein 2. Hindwing blackish brown, distal margin 
and fringe light brown, £ with white apical spots between veins 7 and 8 as well as 8 and 9. 3 40, $ 68 mm. 
Petropolis. 
H. brunnea Schs. Body brown, forewing light brown, costa spotted black, a basal row and a double brunnea. 
interior oblique row of dark brown spots, a median row of larger brown spots, prolonged below the costa, and 
with a fawn tint above the interior margin on both sides. Three silvery spots at the origin of vein 6; a broad 
exterior brown shadow forms spots below vein 5. These spots are bordered with blackish brown and fawn- 
colour on both sides. An antemarginal row of dark lunar spots bordered with fawn-colour outside. Fringe 
fawn-coloured, speckled darker. Hindwing deep blackish brown. 31 mm. Aroa (Venezuela). 
H. tupi sp. n. (99 c). 36 mm. The strongly rubbed off specimen at hand exhibits a bright brownish tupi. 
yellow ground-colour. Dark spots at the costa. A Hepialid triangle and an inner-marginal spot pale flesh- 
coloured. Thorax greyish brown, hindwing and abdomen dark yellowish brown, 1 specimen in Coll. Seitz. 
From Southern Brazil (Ypanema). 
2. Genus: JPhilaeuia Ky. (Pharmacis Mschlr.) 
Hardly separated from Hepialus in the neuration, according to Butler near Oncopera. Antennae of 
the 3 very short, with two rows of pectinations. Palpi very small, hidden. Anterior and middle legs thick, 
with long and dense hair as far as the tips of the tarsi, middle legs y 3 longer than the former ones. Hindlegs 
feeble, only y 3 of the length of the middle legs. Their femora and tibiae less hairy, the tarsi only with appres- 
sed scanty hair. Abdomen projecting beyond the anal angle by %. Forewing with a rounded apex and a rather 
straight margin, hindwing somewhat longer than the forewing (Moschler). 
Ph. lagopus Mschlr. (99 c). Antennae, head and thorax yellowish brown, abdomen greyish brown, legs lagopus. 
yellow, with brown hair. Forewing yellowish brown, broadly dark brown at the costal margin, a similarly 
coloured dark stripe from the base along the inner margin and a similar oblique stripe behind the middle of 
the inner margin towards the margin. The whole wing is crossed by transverse rows of blackish tiny cross¬ 
streaks edged with yellowish. Fringe dark brown. Hindwing dark brown, fringe scarcely lighter. Forewing 
beneath yellowish brown, darker at the margins, spots indistinct; hindwing beneath dark brown, dusted yellow¬ 
ish brown at the margin. 28—35 mm. 2 S3 from Central Surinam. — A form from the Upper Rio Negro 
and Amazons (Pebas) with a silvery stigma in the cell, the forewing ochreous, hindwing grey, basal parts and 
apex ochreous, fringe throughout ochreous, may be introduced as a subspecies ornagua form. nov. 36—40 mm. omagua. 
3. Genus: Dalaca Whr. 
Body rather slender, slightly hairy, mouth and palpi stunted, antennae thick, bristle-shaped, abdomen 
projecting a little beyond the hindwing. Legs rather slender, slightly hairy. Wings rather narrow, costa straight, 
apex somewhat rounded, distal margin rather oblique and slightly convex. Neuration similar to that of Hepialus. 
Antennae of 3 dentate, as long as the thorax, somewhat shorter in the $; hind tibiae long-haired. Forms from 
more than middling sizes to small sizes. Apparently the largest genus inhabiting the whole neotropical region 
from Mexico to Chile. — Another focus of the genus Dalaca is situate in Tropical Africa. Cf. Vol. XIV, p. 555 
seq. and pi. 80. — A number of American species were newly established. The names are chiefly derived from 
the language of the Indian tribes inhabiting those districts. 
D. epigramma H.-Schdff. (185 a). Ground fawn-coloured. Abdomen brownish, forewing darker basad, epigramma. 
lighter towards the apex. A white angular line from the base of the wing to the centre of the inner margin 
and then to 4 / g of the costal margin. Behind it a parallel white submarginal line. Hindwing pink. 46 mm. Brazil. 
D. exclamans H.-Schdff. (185 a) resembles epigramma. Discernible by the note of exclamation at the exclamans. 
cross-vein. The white lines are absent. 50 mm. Brazil. 
D. assa Drc. (99 c). Forewing from yellowish brown to brown-red, 3 undulate transverse lines from assa. 
the costal margin to the inner margin. A dark central spot sometimes shows a silvery centre. Hindwing reddish. 
45—50 mm. Widely distributed and common in Central America, from Guatemala to Panama.
