short transverse stripe. Tibiae and tarsi black. The thorn of the uncus is straight, slender. British and French 
Guiana, Para, Trinidad, also from the Upper Amazons. 
M. pasaleuca Maass. ( = verditincta, niveitincta Dogn.) (160 h) is white, with hardly any gloss and pasaleuca. 
stripe, thinly scaled, the costa of the forewing narrowly black. Much flown specimens are feebly greenish, 
the black costa is then indistinct. West Colombia. 
M. purens Schs. (= mataca Schaus) (160 h) is smaller, with narrower forewings and a distinct black purens. 
costa. Middle and hind legs black, covered with white. Described from French Guiana, the specimen figured 
from South Brazil. 
M. heinrichi Hopp. The white forewing likewise without any transverse stripes, though fresh specimens heinrichi. 
exhibit longitudinal stripes of the forewing between the veins, by which the wings become very lustrous. Costa 
of forewing white, finely black at the base at most. Legs blackish. The uncus-thorn of this species is short 
and thick, curved. Peru, Ecuador, West Colombia. 
The following two species I know only from the descriptions and a photo of the male sexual armature. 
M. terena Dogn. has lustrous white wings. The forewing is a little prolonged at the apex, with a fine terena. 
black costa on the basal half. Middle and hind legs white. The photo of the male sexual armature shows sac- 
culi with a narrow stalk and an almost spoon-shaped terminal jrart, feebly chitinized and ciliated. Tolirna 
(Colombia). 
M. dyari Dogn., according to the description, has a reddish-yellow head, thorax and forewing, the latter dyari . 
with a postmedian row of black streaks from the middle of the inner margin to vein 7; hindwing pale reddish- 
yellow. Bogota (Colombia). The colouring and marking of this species seems to form a transition to Trosia ; 
the close relationship of the two genera is probable owing to the condition of the male 10th abdominal segment . 
14. Genus: jffalmella Dogn. 
According to the organization of the male 10th ventral segment, the genus ranges between Mesoscia 
and Norape. It has an unpaired uncus with which the socii are ventrally entirely grown together, from which 
only a dorsally apical comb of smooth chitine projects, breaking off sharply towards the ventral side. The uncus 
which is thus distinctly isolated prevents the species from being placed to Norape, and the ventral coalescence 
of the socii from being united with Mesoscia. The genus is not discernible by external marks, the length of 
the antennae and peculiarities of the neuration upon which it was established do not prove to be constant. 
Thus also one of the four species originally described as Malmella belongs to Norape, one to Macara , and one to 
Hysterodadia. 
M. strigiprima Dogn. (160 h), the generic type, is a small species with long antennae, the dingy white strigiprima. 
forewing is covered with brownish hair on the costa and all the veins, the vertex, dorsal abdomen and hind- 
wing are white, the legs feebly brownish. From Tolirna in Colombia. 
M. nigricollis Hopp (160 h) looks like a Norape, as the white species exhibits transversely striped and nigricollis. 
thereby glossy silvery forewings and a yellow vertex; the tufts around the antennal base, however, are white 
The collar is broadly blackish-brown, but this occurs also occasionally in species of Norapte. Abdomen without 
yellow colouring, purely white. Middle and hind legs purely white. Peru and Ecuador. 
15. Genus: Repuoa Dyar. 
JRepnoa Dyar (Praenorape Hopp) shows the appendages of the male 10th ventral segment paired; they 
consist of two slipper-shaped, hollow pouches which are delicately chitinized and set with touch-cilia; they 
do not represent the real uncus which has been lost or is rudimentarily represented by a very tiny chitine-staff. 
but the socii. Norape also lacks the real uncus, but the socii rejrlacing it are never paired. — The species di-mi - 
diata Wkr., arpi, thanatos, amarga Schs., cincinnata and fuscoapicata Dogn., which were placed to this genus 
in the older literature, are Megalopyginae. Only 1 species: 
R. imparilis Schs. (= anrazonica Dogn.) (160 h). Only the <$ is known. Vertex yellow, antennae basallv imparilis. 
white. Thorax white with little grey. Abdomen yellow at the base and anus, the rest greyish-brown above. 
Middle and hind legs white. Forewing white, especially the cell and costa; all the veins with lines of brown 
hair. Hindwing also white, the brown lines of the veins narrower. British Guiana, Amazons, East Colombia. 
—■ alba Hopp (160 h) lacks the brown lines on the veins and the brown colouring of the abdominal dorsum, alba. 
but it has no other differences. The white form is known from British Guiana, the Lower Amazons, Espiritu
