M. erratipennis Whr. has violettish-grey forewings, dusted with reddish purple brown in the costal- 
marginal area and at the anal angle, the whole wing watered with violettish-grey striae which are bordered 
with whitish on the inside; the transverse lines are replaced by 2 broad faded shadowy bands, the anterior 
one extending from the first third of the costal margin to the base of the inner margin, the second from near 
the apex to the distal third of the inner margin, the inner margin between these two bands is shaded with 
blackish; a dark streak at the cell-end. Hindwing white. Expanse of wings: 26 -29 mm. Brazil. 
M. simplex Why. Forewing monotonously purple brown, similarly marked as erratipennis, but without 
the watery striations, the two shadowy bands much narrower and somewhat less oblique; indistinct internerval 
dots before the margin. Hindwing not purely white but with a slight grey hue, darkened at the margin. 
Described from Brazil. Expanse of wings: 28 mm. 
M, rubricosa Dogn. Forewing yellowish-pink with a lilac tint above a black, white-strewn oblique 
line from the apex, chestnut-brown below this line, dusted with violet towards the base; a black subcostal 
spot before the first third of the costal margin, and a dot below it, from which an oblique band extends to the 
line which ends in a white subapical spot, 2 smaller ones below it. Hindwing red-brown, yellowish basally and 
at the costal margin, fringe yellowish. Expanse of wings: 26 mm. French Guiana. 
M. leechi Drc. Ground-colour of forewing light reddish yellowish-brown, a dark brown line from the 
apex obliquely to the base of the inner margin, distally bordered with a lighter colour. Hindwing of the same 
colouring. Amazons. Expanse of wings: 34 mm. 
M. frondea Schs. (= costipuncta Rothsch.) (153 a) lacks the oblique line; forewing light brown, warming 
into yellowish at the distal margin, dusted with violet at the base and median area, and at the costal and 
inner margins; a black dot at the cell-end; costal margin very convex, with a velvety brown broad stripe 
in its centre. Hindwing light reddish-brown, lighter towards the base. The species seems to be rather variable, 
particularly in the intensity of the more or less dark violet dusting. Expanse of wings: 34 mm. French Guiana. 
99. Genus: Kifargia Wkr. 
This genus is a parallel branch of Heterocampa (Disphragis) or Malocampa, almost nearer to the latter 
owing to the hair at the base of the hindwing beneath; the only mark of distinction is that the antennae 
are not pectinated but tuftedly ciliated. This genus also abounds in species and forms. A monography treating 
upon them will have to subdivide the genus into several subgenera. The genus contains many large species 
often of a beautiful colouring and marking, such as the picta-group. 
Type of genus: R. xylinoides Wkr. 
R. xylinoides Wkr. (= cloelia Schs.) is brownish-black on the forewing, tinged with moss-green at the 
costal and inner margins as well as behind the cell, with a black-edged reniform macula at the cell-end; both 
the transverse lines indistinctly double, the anterior one extending to the inner margin in three arches, the 
posterior one dentate and with black and white vein-dots which reoccur at the base of the fringe; a light 
brownish-yellow patch divides the apex from where it extends below the median vein almost to the base. 
Hindwing greyish-brown. Expanse of wings: 36 mm. Brazil. 
R. mortis Schs. (153 a) is allied to xylinoides and was treated at last by its author as a synonym to 
Disphr. gelduha (p. 970). I had mentioned there that I consider it to be different, because in my opinion the 
q' of gelduha, which undoubtedly looks very similar, is to be distinguished by its pectinate antennae and 
to be placed to gelduha. Forewing dark blackish-grey, strewn with moss-green at the centre of the costal 
margin, with a velvety black cell-end streak; traces of darker transverse lines, the posterior one with white 
vein-dots; a light reddish-yellow shadow divides the apex, an indistinct dark submarginal shadow below it 
extends to the anal angle above which there is a black thick dot. Hindwing dingy white, strewn somewhat 
brown at the costal and distal margins. Expanse of wings: 33 -35 mm. From Guiana to Argentina. 
R. muscosa Dogn. is near mortis-, forewing greenish-grey, partly strewn with lilac grey, with the same 
transverse lines as in mortis, the anterior one more distinct, double, and likewise with white vein-dots; the 
light apical oblique streak is narrower and much longer, extending to the middle radial vein. Hindwing more 
purely white, only brownish at the costal margin and apex. Expanse of wings: 30 mm. Argentina. 
R. morula Dogn. also belongs to this group and has blackish-grey forewings extensively strewn with 
green basally, in the centre of the costal margin, in the distal half of the cell, submedianly and at the margin; 
all the markings very difficult to discover in Ihe dark ground, the posterior transverse line marked by a double 
row of white vein-dots, the black cell-end streak distally dusted somewhat red-brown; black subterminal dots
