near the base. Exterior line also double, from near the apex to 2 / 3 inner margin, distal margin brown, rusty 
yellow at the apex. Hindwing white at the costal margin. Interior line brown, slightly bent, darker before 
it. Exterior line double, bent. Marginal area more intensely dark, with a light median band. A $ from Bolivia 
is very large, dusted much darker. On the other hand there are also specimens showing hardly any brown dusting 
at all. 25—30 mm. Nicaragua, Colombia, Bolivia. 
The following species were formerly ranged under the genus Syngria, but as their neuration is different, I 
place them here. The antennae of the $ seem to be somewhat longer pectinated, the scheme of marking in acalis is 
very similar to that of Syn. druidaria (170 f), the other species are differently marked. 
M. acalis Fldr. (170 d) is rather variable. Wings creamy white. Forewing narrowly violettish brown at acalis. 
the costal margin, the basal half as far as the cross-vein also violettish brown, mostly less prominent below 
vein 2. Sometimes a yellowish interior line in it, recognizable as in druidaria (170 f). Exterior line yellow, 
edged with brown inside, from the costal margin straightly outward to vein 4, where it is sharply angled, and 
curved to the inner margin. A subapical black dot. Brown at the margin especially in the lower part. Hind¬ 
wing with an exterior line between veins 6 and 2 as in druidaria , sharply angled at vein 4, whitish, edged with 
brown inside. Rusty brown above the lowest small tail, adjoining to it a submarginal band of brown scales. 
One part or another of the marking may be absent, rarely everything is present. 26—30 mm. Central America, 
Colombia. — griseata Warr. (170 d) is probably only a very dark specimen in which the dark dusting on the griseata. 
forewing extends to the extinct exterior line, while the light exterior line on the hindwing is not prominent in 
spite of the intense darkening. 34 mm. Peru. 
M. versilinea Dgn. is probably a separate species. Ground-colour greyish white with dark streaks, versilinea. 
especially at the costal margin of the forewing. The two lines white, edged with brown at the costal margin, 
the interior line bent, the exterior one as in acalis (170 d). Beside the black subapical spot there are yet black 
streaks in the marginal area. Costal margin of hindwing white, the rest like the forewing. The exterior line 
projects pointedly at vein 4. 32—36 mm. Ecuador, Colombia. 
M. candidata Warr. (170 e) is very different. Ground-colour white. Forewing with a dark brown marking, candidata. 
A double streak at the cross-vein down to vein 2. Exterior line slightly outward at the costal margin, then 
vertical, double as far as vein 4, where it is very fine, prolonged towards the base, then distinct again, vertical 
double, to 3 / 4 inner margin. Submarginal line interrupted. Exterior line of hindwing double, somewhat angular 
in the middle, not reaching the costal and inner margins. Submarginal line traceable, a black spot above and 
below it near the anal angle. 30 mm. Peru. 
M. albipennaria H.-Schdff. (170 e) is somewhat similar to candidata. Wings white with light olive brown albipennaria. 
transverse lines. Forewing with an interior line from x / 4 costal margin to x / 3 inner margin. Median line double, 
straight, slightly oblique. Exterior and submarginal lines composed of dense striae, parallel with the median 
line. Hindwing with a double median line. The two other lines only formed of striae meeting at an intense 
spot above the anal angle. The anal angle itself rusty yellow. 30—35 mm. Venezuela, Colombia, Bolivia, Brazil 
? M. cinerea Warr. (170 d). Dark grey, dusted black. Forewing with traces of 3 faded black bands at cinerea. 
the base, before the middle and at % of the length of the wing, the last somewhat more distinct, extra-angular 
in the middle, below it curved inward. Veins in the marginal area paler. Hindwing with black scales at the 
base. Traces of a median and submarginal shadowy band. Paler grey at the inner margin. Veins yellowish 
ochreous. Black dots near the anal angle. 24 mm. Venezuela. 
ramosaria Mschlr. placed to this genus by Dalla torre belongs to the Geometridae. 
15. Genus: Solifriax Hbn. 
Forewing pointed at the apex, slightly cut out below it, excurved at the middle of the distal margin. 
Veins 3 and 4 near the lower cell-angle, 5 a little below the upper one, 6 -|- 7 on a short stalk, 8 -f- 9 on a longer 
stalk. Hindwing with 2 bows near the anal angle and a rounded margin. Antennae of G a nd $ pectinate. Type: 
squammularia Hbn. 
S. squammularia Hbn. (170 e). Wings greyish white, striated dark. Anal angle of forewing and exterior squammu- 
half of hindwing brown, rarely with a brown median band as Hubner figures the species. Interior line of fore- laria. 
wing from y 3 of costal margin fine, black, dentate, very obliquely inward. Exterior line projecting in the middle 
of the wing, very strongly notched. 25—30 mm. Nicaragua, Cayenne, Brazil. 
S. anosedaria Gn. (170 e). Wings greyish brown with dark striae. Forewing often somewhat darker anosedaria. 
at the cross-vein and anal angle. Exterior line of forewing dark brown, shaped as in squammularia, no interior 
line discernible. 28 — 30 mm. Brazil. Erosia similaria Wkr. is probably the same species. 
S. evulsa Fldr. (170 f). Similar to a large anosedaria. Reddish brown. Interior and exterior lines of evulsa. 
forewing fine, distinct, black. Interior line excurved in the middle, exterior line finely notched, straight as far 
as vein 3, incurved between veins 3 and 1. A black streak before the exterior line at the costal margin. A dentate 
marginal line parallel with the margin. Hindwing greyish brown, with the light spots at the anal angle as in 
the two preceding species, but larger, the distal margin more excurved. 40 mm. Guiana.
