Eucereon hoffmannsi, Roths. Nov. Zool. xix. p. 180 (1912), nec p. 170.

Head and thorax grey tinged with brown; antennae and palpi behind dark
brown; patagia edged with brown; legs brown; abdomen dark brown, the
extremity yellow, the ventral surface brownish white with brown segmental
lines on terminal half. Fore wing brownish white, the veins, discal fold in
end of cell, and submedian fold streaked with brown; traces of an oblique
brownish subbasal line; antemedial line brown, rather diffused towards
costa, angled inwards at median nervure and outwards in submedian fold; a
rather quadrate brown discoidal patch conjoined to a spot on costa from the
outer edge of which arises the postmedial line, strongly excurved between
veins 5 and 3, then oblique to the submedian fold where it is angled
inwards to the antemedial line, then angled outwards at vein 1; subterminal
line brown, excurved and forming a patch at vein 6, excurved at middle and
angled inwards at vein 2 to near the postmedial line; an oblique maculate
subapical brown bar from costa to vein 6 and a small spot at extremity of

sp. nov. (the preoccupied name replaced by Hampson's pagina).

141. Eucereon hoffmannsi sp. nov.

Male. Similar to lineatum Dogn. but much smaller. Differs in the
ground-colour of forewings being pale testaceous, not semihyaline white,
the markings less sharply defined and of a dull wood-brown, not bright
chocolate. Anal segment of abdomen bright yellow, not dirty brown.

Length of forewing: hoffmannsi, 20 mm.; lineatum, 25 mm.

Hab. Pozuzu, Huanuco, Peru, 800-1000 metres (W. Hoffmanns) (type);
Paramba, Ecuador; Quevedo, W. Ecuador (von Buchwald).

The species Rothschild compares with, Eucereon lineatum (Dognin, 1891), as
described by Hampson (1898), Catalogue of the Lepidoptera Phalaenae in the
British Museum, vol. 1: pp. 512-513, no. 1130:

1130. Eucereon lineatum.

Theages lineata, Dognin, Lep. Loja, p. 48, pl. 4. f. 5 (1891); Kirby, Cat.
Het. p. 905.

Head and thorax reddish brown and white; abdomen fuscous, with some whitish
scales at base and extremity; obscure series of white lateral spots and
ventral bands. Fore wing whitish, thinly scaled; a short reddish-brown
subbasal band from costa; two obliquely curved and irregularly dentate
antemedial lines; a pale-centred figure-of-8 shaped discoidal patch
extending to costa; two irregularly dentate and obliquely curved postmedial
lines, the outer expanding into patches towards costa and inner margin; an
obscure irregularly dentate subterminal line expanding into patches at
costa, middle and inner margin; some terminal points on the veins and a
terminal line. Hind wing hyaline, the veins and terminal line brownish.

Hab. Ecuador, Loja; Bolivia, Chaco (Garlepp), 1 male. Exp. 46 millim.


Draudt, M. (1915). Eucereon. In: Seitz, A. (ed.), The Macrolepidoptera of
the World, vol. 6, The American Bombyces and Sphinges: p. 183, as
E. hoffmannsi Rothsch. (German edition: Die Gross-Schmetterlinge der Erde
6: 183.)

E. hoffmannsi Rothsch. is much smaller than the preceding. The forewings
are not semi-diaphanous whitish, but light yellow-brownish, the markings
much less distinct and of a dull wooden-brown colour, not chocolate-brown.
The last abdominal ring is of a bright yellow, not dirty-brown. Length of
forewings: 20 mm. Peru; Ecuador.

The preceding species referred to, E. lineatum Dogn. (Draudt, same page):

E. lineatum Dogn. has a reddish-brown head and thorax, mixed with white.
Abdomen blackish-brown, anteriorly and posteriorly with interspersed
whitish scales, with whitish lateral spots and ventral bands. Forewings
whitish, thinly scaled; near the base a short, reddish-brown band; 2
antemedian, irregularly dentate lines; at the cell-end a spot in the shape
of an 8; 2 postmedian dentate transverse lines, the distal one thickened
to a spot at the costa and proximal margin, and a similar, antemarginal
line thickened also in the middle; a marginal line and dots at the ends of
the veins. Hindwings hyaline with a brownish border and veins. Expanse of
wings: 46 mm. Ecuador; Bolivia.
