M. regis sp. n. (68 c). Body yellowish-brown, in some places blackish, particularly two abdominal regis. 
lateral stripes which are posteriorly fused on the dorsum, under surface whitish-yellow. Basal half of forewing 
lighter yellow, apical half and costal margin and hind-margin narrowly black. Costa, subcosta, and anterior 
edge of the cell along the same spot yellow. In the apical half a more orange-yellow spot, the hindwing darker 
yellow, apex and distal margin black, the latter angular at the 2nd median. Behind the cell a black basal spot. 
Sometimes the yellow colour is uniform in all the spots. Peru, Rio Pachitea, and Puerto San Matro (<J-type)

M. celata Warr. resembles priverna (68 b), the cliscal band in the forewing is merely a small spot situate cclafa. 
farther proximad. All the veins in the forewing pale, beneath the yellow colouring more extensive; only 
the apex, distal margin and hind-margin, and a wedge-shaped costal spot filling up also %of the cell remain 
black. The expansion of the yellow discal spot also shows through above. Hindwing yellow, apex and distal 
margin black, the base also a little dusted with black. •— Whilst in the normal form the costal spot of the 
forewing above is small, occupying only the space between the veins 10 and 11, it is larger and broader in

M. biplagiata Warr. Forewing brown, veins yellow, with 2 orange-yellow spots, one beyond the cross- biplagaia. 
vein below the costal margin extending to vein 4, the second behind the cell, extending beyond vein 2 and 
posteriorly to the axillaris. Hindwing orange-yellow, with a narrow black border, at the costal margin and 
distal margin as far as the tornus. Forewing beneath with the yellow spot extended behind the cell to the base.

hindmargin, thus filling up the greatest part of the anal area. Peru. Expanse of the <$: 32 to 34 mm. 
M. graba Drc. (68 c) is similar to biplagiata, the yellow spot behind the cell in the forewing beneath grata.

(width y 3 of the wing), base black, sometimes beneath connected with the marginal band. Peru, Upper Amazons, 
Ecuador. — In the form primula Dgn. the spot behind the cell is prolonged to the hind-margin. primula. 
M. papula Dgn. Forewing chestnut-brown, costal margin as far as % finely yellow, veins paler; a papula. 
yellow flattened spot in the posterior centre of the cell, another one distally to the cross-vein, being larger 
in the female, whilst the first disappears. Hindwing yellow with a distal margin of about 2% mm, but narrower 
on the 2nd median. In the $ on the hind-margin, analis and in the cell a short black basal ray, in the $ only 
traces of it. Forewing beneath blacker, spots more yellow, the postdiscal spot enlarged, with a large yellow 
basal spot. Hindwing without basal streaks beneath. Expanse 35 mm. Amazons. 
M. ederi Prt. approximates graba (68 c), the yellow markings are lighter and more extensive, the distal ederi. 
margin of the forewing is less slanting. The spot below the cell in the forewing begins near the base and extends 
much farther towards the margin, so that it is almost fused with that behind the cell, being only separated 
from it by a dark line along the 3rd median. The black margin of the hindwing of an average width of 3 mm, 
as in graba. Expanse q 37 mm. South East Colombia. 
M. projecta Warr. resembles ederi, the markings in the forewing are whitish-yellow, in the hindwing projeda.

M. augusta Warr. Forewing blackish-brown, with a golden yellow discal band being broadest in the augasta.

band. Hindwing golden yellow, with a broad black distal-marginal band, the broadest at the apex and tornus. 
Beneath the costal margin of the forewing is yellow as far as the centre, fringes at the apex white; in the 
hindwing at the apex a yellow spot in the black distal margin, a basal black streak below the costal margin,

M. cuneiplaga Prt. differs from augusta in the abdominal dorsal line being broken up into spots, the cuneiplaga. 
distal band of the forewing being more slanting, directed towards the tornus, almost equally wide; hindwing 
above only with a reduced, streak-shaped central area, the greatest width of which is 2 y 2 mm, beneath broader

M. prouti sp. n. (68 d) is similar to the two preceding, the dorsal line of the abdomen broken up into prouti.

the yellow apical spot, costal margin black, the broadest at the base, connected with the black distal margin,

in front, inner edge of patagia, and lateral stripes of abdomen yellow, abdomen beneath whitish. Expanse

equally coloured smaller spot. Beneath the veins are not yellow, the proximal spot as above, not extending 
on the median to the base, the distal spot being much larger. Hindwing lighter whitish-yellow, the margin 
3 to 4 mm broad black, the anal margin, base, and costal margin basally narrow black. Beneath the
