another white line extends in a slight S-curve and upwards convex bow to 1 cm before the anal angle; subterminal 
band blackish-brown, with 2 bows towards the margin between 2 and 4. Hindwing lighter, at the base with 
somewhat brownish ochreous hair, with a large very indistinct discal spot and a light submarginal line which 
is bordered with dark on both sides. Brazil (Parana; Minas Geraes). 
21. Genus: Mesoleuca Pack. 
Some few evidently closely allied species at once discernible by the long-stalked course and mostly 
also contrasting colour of veins 5 and 6 of the hindwing; on the forewing 6 and 7 are also distinctly stalked. 
Mostly thinly scaled, rather small insects of a characteristic exterior. The seem to be without wings. 
Type: M. venosa Wkr. 
M. venosa Wkr. (118 a). Wings whitish, with fine black veins and fringes, and a smoky brownish narrow venosa. 
subterminal line parallel to the margin on both wings. — Body black, collar yellowish-grey, ventrum and sides 
with orange rings, anus copper-red or black. — nigra Dogn. (118 a) is scaled smoky blackish excepting the nigra. 
light cell-end. Dognin describes a $ belonging to it to be quite black and without wings. Colombia (Bogota; 
Sabatoga). 
D. famula Maass. (118 a) is smaller scaled blackish on the olive-yellow ground, at the costal and distal famula. 
margins and on the hindwing more densely scaled, with black veins, a yellow angular spot at the cell-end and 
a yellow submarginal line; the yellow fringe is speckled with black. Abdomen with yellow and black rings, 
anus red. Ecuador. 
D. nata Maass. is very similar to famula, browner, more densely scaled and less transparent, the yellow nata. 
postmedian line more remote from the margin and inwards bordered with a darker brown, only the forewing 
with black veins, hindwing brown with ochreous fringe. Ecuador. 
22. Genus: Kentroleuca gen. n. 
Only 1 species originally described as Heliconisa, with broad wings, an almost Geometrid-like habitus 
and a slim body. On both wings veins 6 and 7 most characteristically stalked; lower cell-angle far produced 
especially on the hindwing. Palpi short with a very small terminal joint. Anterior tibiae at the end inside with 
a very strong slightly bent horny sting of % the length of the tarsus, and outside a short one; hind tibiae with 
a pair of short terminal spurs. 
0, lineosa Wkr. (118 b). Front body yqjlowish grey, abdomen above ochreous, beneath white. Antennae lincosa. 
brown. Eorewing smoky blackish, with fine yellowish ochreous veins on both sides bordered with whitish, and 
a creamy white discal and submedian fold, the base of the wing between the light veins distally obliquely cut 
off black; a white slightly oblique subterminal line which projects distally somewhat arcuately between the 
veins and is darker edged towards the inner margin. Hindwing the same, the line less distinct and bent parallel 
to the margin. Fringe white. Brazil, apparently very rare. 
23. Genus: Hfrpida gen. n. 
Like the preceding genus of a somewhat Geometrid-like habitus, apex of fore wing slightly falciform. 
Palpi shorter than in Kentroleuca, antennae of <$ with short pectinations. Neuration quite the same as in 
Kentroleuca ; the horny sting of the anterior tibia is absent. 
Type: H. gaujoni Dogn. 
H. gaujoni Dogn. (= choba Drc., $-nigrolinea Drc.) (118 b). Body and forewing light red-brown, base gaujoni. 
and marginal area with a cinnamon pink hue and dusted with lilac white, with 2 transverse lines, the posterior 
one distinctly and regularly notched, between them a black discal dot and behind it a straight broad shadowy 
band; between the notched line and the margin some interrupted parts of a lilac grey subterminal line. Hindwing 
with an indistinct straight postmedian line, at the anal angle dusted with lilac grey. Beneath with 2 straight 
lines behind the discal dot. Ecuador; Bolivia; Peru. 
H. rubella Dogn. (118 b), described as Saturnia, is very closely allied to gaujoni, distinguished by the rubella. 
more purple pink ground-colour; discal dot and median shadow as in gaujoni, but instead of the regularly 
dentate postmedian line there is here an irregular hazy double shadowy line. Ecuador.
