a) White species. 
M. vestalis Pack. (39 c) is entirely white, like a white Spilosoma, the anterior femora above rosy- 
red, but the abdomen in typical specimens banded black, in the form amelaina Dyar (39 c) there are traces 
of blackish markings or they may be absent; but in that case always to be recognized by single, small 
black dots on both wings. Mostly the small dark dots on the veins form antemedian and postmedian rows 
on the forewing. Also in the middle of the hindwing at least 1 black dot, whereby the species can be discerned 
from the otherwise similar Estigmene congrua. This species also only occurs in the western parts of the United 
States. 
M. jussienae Poey (39 d) is entirely white like a vestalis amelaina, but only half its size. Only at 
the cell-end of the forewing a small black dot. Cuba. 
M. pelopea Drc. (39 d) is white with a yellow head and abdomen. The veins of the forewing fine 
though distinctly black. Mexico. 
b) Green species. 
M. aeruginosa Fldr. (39 d). Pale light green, the hindwings lighter, the abdomen above spotted darker. 
In the lower cell-angle of the forewing there is often a small black dot. Colombia, in December in Bogota and 
its environs. 
M. underwoodi Rothsch. Thorax and forewings apple-green, the latter speckled brown, with a dark 
postmedian band. Hindwings pale apple-green, with a brown inner-angular spot; abdomen brick-red. Costa Rica. 
M. ockendeni Rothsch. Body above turquoise-blue, forewings of a Veronese green, hindwings semi- 
diaphanous light whitish-green. South East Peru; based upon l single $ with very convex margins of the wings. 
M. aldaba Dogn. Like the preceding, quite pale green, but the forewing with a scarlet costa, a small 
black spot at the lower cell-angle, and a black, dentate post-median line, being strongly angled in. the two folds, 
30 mm. Loja (Ecuador). 
M. viridis Dogn. is another green species from South Peru. It has an expanse of 37 mm, being 
quite green, but the forewing of a deeper green rvith two irregular, black transverse lines; the proximal one 
at the median angled, the distal one, behind the cell, sending truncate teeth over 3, 4 and 5. Besides the forewing 
has a red costal margin and a small black spot near the base. Hindwing with a small dot in the cell, and a 
post median curved line. 
M. lymphasea Dogn. Described as Phragmatobia, placed to Diacrisia by H amp son. Green, hindwings very 
much lighter than the forewings. The latter with a pink costal margin. Abdomen likewise pink. Ecuador ; Loja. 
M. irrorata Rothsch. (39 f). Forewings light green, but so densely speckled brown that the ground¬ 
colour almost disappears, in the basal half there is a brown X, at the cell-end a chocolate spot. Hindwings 
greenish white. Huancabamba (Peru). The species in its structure deviates so much from the other species 
of the genus that Hampson established for it the genus Chlorocrisia. 
c) Species with a yellow ground-colour. 
M. intricata Wkr. (39 d). Dull milky-white ^orewings with bands of brown streaks, at the base, 
through the middle and at the margin, alternating with fine rows of dots. At the cell-end of all the wings a 
yellowish-brown shade. South Brazil, near Rio, Santos etc. 
M. alcumena Berg from Argentina is larger, of a purer white, marked darker brown, at the cell- 
end of the forewing a small orange spot bordered with black. Is reported to occur together with intricata, without 
any transitions, for which reason it is probably a distinct species. — In steinbachi Rothsch. (39 d) the median 
band composed of stripes is replaced by a brown homogeneous band; from East Bolivia. -— flavitincta Rothsch. 
from Venezuela has the streak-bands through the forewing greatly reduced. — kennedyi Rothsch. from Minas 
Geraes has the hindwing more intensely tinged yellow in the proximal half. — On the whole, the species is 
distributed very far, and very common, the butterflies coming particularly often to the lamp. 
M. pulverea Pimps. (42 i), from Paraguay (Sapucay) and North Argentina, has an orange head and 
thorax, and dark blackish-brown palpi, forehead, antennae, tibiae, and tarsi. Abdomen orange, above and 
laterally rows of black punctiform spots. Forewings orange-yellow, finely dusted brownish; hindwings likewise 
orange. 36 to 40 mm. 
d) Species with hyaline w i n g s. 
M. hyalina sp. nov. (42 h). This species, according to its nature, would have to be inserted in the 
large genus Diacrisia in Hampson’s sense, which, however, comprises rather heterogeneous elements, and it 
is possible that the form has already been described by another genus. All the wings, except the costal-and 
inner-marginal areas, purely hyaline, the yellow costal stripe with 3 black spots, the brownish inner-marginal 
area with 2 median streaks. Abdomen orange-yellow, the middle rings black. Fassl brought it from Colombia.
