M. seniiplaga Warr. is distinguished from the 3 preceding species by the absence of the white apical smuptuga. 
spot on the hindwing beneath. The central area of the hindwing terminates behind on the median. Colombia. 
— In pleniplaga Prt. the hyaline central area is extented yet behind the median in the hindwing. Bolivia. plentplaga. 
M. avara Drc. Like sobria (68 e) with a white abdominal line and white apex of the hindwing beneath, avaru. 
instead of the discal spot there is a cliscal band in the forewing, which, however, does not reach to the costal 
margin. Expanse 38 mm. Ecuador. 
M. corsigera Prt. Hindwing beneath without a white apex, forewing with a white discal band as in conigera. 
avara on the hind-margin, but more proximally, shorter, being broadest behind, not traversing the cell. East 
Peru. 
3. Wings with a dark ground-colour, without hyaline areas ( Myonia ). 
M. lindigii Flclr. (68 e). Patagia uni-coloured. Wings blackish-brown, forewing with an orange diacal'lindigii. 
band, hindwing with an intense blue lustre, with an orange costal spot before the apex. Panama, Colombia. 
M. leechi Prt. Patagia with a yellow stripe. Smaller and with narrower wings than lindigii, the yellow leechi. 
band of the forewing much broader, not reaching to the axillaris. Hindwing without a yellow apical spot, the 
blue lustre only present in the anal part. Amazons. 
M. decolorata sp. n. (68 f) approximates lindigii, but the hindwing is without any blue lustre, the decolorata. 
yellow markings are of a deeper orange-yellow, the discal band of the forewing is broader, at the costal margin 
widened, the apical spot of the hindwing larger, otherwise entirely corresponding with lindigii, also in its size. 
Brazil, Leopoldina. $-t.ype in the Berlin Museum. (In the habitus the species looks like very large Brachygleyie 
caenea Drury.) To this species probably belongs another $ from Panama, being somewhat smaller, with quite 
whitish markings, but otherwise corresponding with the type. 
M. euryzona Prt. Forewing similar to leechi, basal half black, principal veins of a thicker yellow, a ~euryzona. 
yellow central band of 4 to 5 mm width from the costa to close in front of the tornus, apical half black. Hindwing 
black, suffused with blue (except at the distal margin), a narrow whitish costal stripe which grows broader 
and yellow towards the apex and expands in an apical spot. Forewing beneath with a whitish basal streak 
in the cell, before it some orange scales, the yellow band broader. Hindwing beneath not blue, but with a distally 
widened white stripe behind the cell and the 3rd median, another shorter and thinner one behind it. Expanse 
32 mm. Bolivia. 
M. depravata sp. n. (68 f) is similar to decolorata (68 f), smaller, the band of the forewing yellowish- depravata. 
white, steeper, not broader at the costal margin, narrower at the hindmargin; apical spot of hindwing likewise 
whitish, smaller: half of 3rd palpal joint yellow, and a yellow stripe on the patagia. Abdomen blackish-brown, 
with a yellow lateral line, beneath narrowly dirty white, at, the end yellow. Length of forewing 12 (<$) and 
16 ($) mm. (£$-types from the Orinoco in the Berlin Museum. — Whilst in the nomenclatural race the white 
band is 2 mm broad at most and tapers off posteriorly, it is in the Bolivian race aniplificata subsp. nov. 3 mm amplificaia 
broad and posteriorly hardly narrower. $-type in the Berlin Museum. -—- In flavifascia subsp. nov. the light jlavifascAa. 
markings are yellow, the band posteriorly not narrower, the apical spot of the hindwing larger. Peru. 2-type 
from Yurimaguas in the Berlin Museum. 
M. saga sp. n. (68 f) resembles depravata, the apical spot of the hindwing is absent, replaced by a saga. 
narrow costal-marginal streak. Palpi black, frons, stripe on the patagia and a dorsal line across the thorax 
and abdomen whitish, abdomen beneath broader white. Distal margin of forewing less convex than in depravata. 
Venezuela. §-type from Puerto Cabello in the Berlin Museum. 
M. labana Drc. (68 f). Blackish-brown, veins of forewing scarcely lighter, forewing with a uniform labana. 
white transverse band, hindwing only with a narrow yellow streak at the costal margin before the apex, beneath 
w r ith a large yellow apical spot. Ecuador, Brazil. 
M. aequivoca Warr. (68 f) resembles labana, but lacks the yellow apical spot of the hindwing and the aequivoca. 
blue lustre. Expanse 39 mm. Venezuela, British Guiana. 
M. Ursula sp. n. (68 f). Blackish-brown, abdomen beneath and on the sides whitish, forewing with ursula. 
a yellow transverse band, hindwing uni-coloured, above with a slight blue reflection. Brazil. Forewing somewhat 
narrower than in aequivoca, the band of the forewing begins a little more distally and is quite straight, in 
aequivoca somewdiat distally convex. 
M. desmotrichoides sp. n. (68 f). In the habitus very similar to the Syntomid genus Desmotricha desmoiri- 
(pl. 23 c); frons white, head, collar, stripe on patagia, middle line on thorax, lateral lines and a dorsal spot clmdc* 
at the posterior edge of the 3rd segment on the abdomen yellow, ventrum whitish. Wings long and narrow. 
Forewing in the basal half with pale yellow veins, in the centre with a yellow transverse band as far as the 
axillaris and white apical fringe. Hindwing with a narrow yellow r costal-marginal stripe and a yellow’ oblong
