The body is tinged whitish-grey and in the beneath and on the last ring also above reddish-yellow. In the 
g the wings are of a pure white, only the proximal-marginal part being blackish-grey. Expanse of wings: 34 mm. 
Ecuador. 
89. Genus: IVephelosia Hmps. 
Proboscis fully developed; the short palpi are straightly porrect; forehead rounded. Forewing narrow 
with a rounded costa and oblique margin; the upper median vein and the two lower, long-petioled radial veins 
rise from the lower cell-angle; the upper radial vein on a common footstalk with the 3 lower subcostals; the 
1st subcostal vein anastomoses with the costal. On the hindwing the upper median and lower radial vein are 
on a very long footstalk, the middle radial being absent, the upper one anastomosing with the subcostal vein. 
The costal vein rises pretty close to the cell-angle. The genus contains only 1 species: 
. N. caecina Drc. (36 g). Head and thorax blackish-brownish, mixed with grey. Abdomen blackish- caecina. 
brown with a yellow anal tuft. Forewing whitish, in the basal half tinged brownish and strewn with black; 
in the inner-angular area there is a large, blackish spot. Hindwings blackish-brown. Expanse of wings: 20 mm. 
Guatemala. 
90. Genus: Areva Wkr. 
Separated from the preceding genus by the upper median, resp. upper radial veins of the forewing rising 
below the corresponding cell-angles; the transverse vein runs very obliquely. On the hindwing the upper median 
and lower radial vein are on a shorter footstalk, the middle one being absent, and the upper one petioled with 
the subcostal vein. 4 species are known of this genus: 
A. laticilia Wkr. (= jubata Fldr.) (37 k) is distinguished from the other species by long hair in laticilia. 
the lower cell-half of the forewings beneath; the costal margin of the hindwing is lobularly convex and covers 
these hair. The transverse vein of the forewing runs so obliquely that it appears in one line with the median. 
The forewings are white with a darker, brownish-grey inner-marginal half and a brown costa; hindwings 
tinted yellow, with a brownish margin. In the $ the proximal margin is brown only as far as the submedian 
fold. Expanse of wings: 40 mm. Venezuela. 
A. subfulgens Schs. (37 k). Vertex and thorax yellowish-white, the rest of the body brownish-grey, subfulgens. 
Forewing blackish-brown, with a coppery lustre, with a yellowish-white inner-marginal stripe, median and 
marginal bands. Hindwing brownish-grey, in the basal and inner-marginal half whitish. Expanse of wings: 
30 mm. Brazil. 
A. trigemmis Hbn. (= ziza Drc.) (37 k) has a darker blackish-brown body with whitish spots on trigemmis. 
its collar, shoidder-covers and mesothorax. Forewings blackish-brown with a purple and coppery lustre; small 
whitish spots at the base of the proximal margin, below the middle of the costal margin, above the submedian 
fold and below it near the proximal angle, and in the middle of the margin. Hindwings blackish-brown, towards 
the base whitish. Expanse of wings: 32 mm. Known from Mexico, Brazil and Hayti. 
A. albogrisea Rothsch. (37 k) differs from the preceding by much lighter markings. On the purple- albogrisea. 
brownish forewings are whitish: the base of the proximal margin, a costal-marginal spot above the cell-end, 
a band behind the cell, and a longitudinal diffuse patch on the upper radial, a band from the cell-end to the 
proximal margin, and a longitudinal diffuse patch towards the proximal angle; besides there are small whitish 
spots close in front of the margin. Hindwings light brown, towards the base whitish. The body is light brown, 
collar and shoulder-covers white. Expanse of wings: 30 mm. Ecuador. 
91. Genus: Metareva Hmps. 
A large accessory cell of the forewing separates this genus from the preceding; the upper median vein 
is removed to the lower cell-angle. Hindwings like in Areva. 
M. aenescens Hmps. greatly resembles A. trigemmis (37 k), but it is bigger with larger, more clearly aenescens. 
white spots. Head and shoulder-covers with a blue lustre. Expanse of wings: 40 mm. Bolivia. 
M. flavescens Dogn. (= semidivisa Rothsch. (37 k). Body yellow, on the vertex, thorax and shoulder- flavescens. 
covers tinted lilac-grey; wings above and beneath straw-coloured, the forewing at the costa finely bordered 
with yellow, and along the proximal margin with a broad, lilac-grey band. Expanse of wings: 37 mm. Tucuman 
(Argentina). — albescens Dogn. (37 k) from the same habitat is the $ of it and differs by all the straw-coloured albesceris. 
parts in the being silvery white here; only the antennae, palpi, forehead and collar above are yellow. Expanse 
of wings: 39 mm. 
M. endoscota Hmps. differs, according to the description, only by its smaller size and the absence endoscota. 
of the yellow of albescens : head and thorax white, tinted blackish-brown; abdomen white. Forewings silvery 
white with a blackish-brown inner-marginal stripe. Hindwings purely white. Expanse of wings: 34 mm. South 
East Peru. 
92. Genus : Procrimima Hmps. 
On the narrow forewing the upper median vein rises before the cell-angle, the 1st radial vein from the 
upper angle, the 3rd subcostal vein being absent, the 1st subcostal vein anastomosing with the costal. On the
