[160 g], (= metaleuca Drc. with donckieri Dogn., obsolescens Dyar ) and — rosita-forms (rosita Schs.) (160 g); 
quite red-coloured forms, as we have figured one, are extremely rare. A melanistic aberration of climas, which 
may be named — ab. nigra (1601), is deep black in all its parts, but the forewing exhibits yet the transverse 
row of spots. From Peru (Tring Museum). 
T. punctigera Stoll (160 g) is less variable, the flava- and rosita-forms of dimas have not been observed 
here. The distal-marginal area of the white forewing usually exhibits a more or less intense tinge of smoky 
brown which may be narrower or broader, so that the fringes appear to be interrupted white; sometimes, however, 
they are also blackened. The generally rather broad red costa of the forewing is followed by a white precostal 
streak. Forewing beneath red with the precostal white streak, but sometimes also entirely white. Hindwing 
mostly quite red, sometimes white at the base (form amala Dyar which, however, is by no means confined to 
Mexico). The transverse band of black spots through the forewing shows irregularities only of the inner-mar¬ 
ginal spot which may be of a red colour and removed more distally. The abdomen of punctigera is generally 
red also beneath, being another mark of distinction from dimas. A particularly white-coloured form is —- anax 
Dogn. (160 g) exhibiting white forewings with a red costa, and white hindwings with sometimes red-edged 
distal margins, while the abdomen beneath and the anus are white. This form is hitherto known only from 
Villavicencio (Colombian Eastern Cordilleras). 
T. roseipuncta Drc. (160 g) is a normally coloured dimas from which it differs only in the red, instead 
of black, spots of the band on the fore wing, in the absence of other chromatic forms and in its being confined 
to South-East Peru. 
T. fallax Fldr. (160 g). The transverse band of black spots through the forewing lacks the third dot 
(counted from the costa). The species is apparently constant in its colouring and marking, but the forewing, 
excepting the red costa, is rather uniformly greyish-pink distinctly contrasted by the white fringe, just as on 
the red hindwing. The tibiae and tarsi are covered with long white hair on one side. On the Rio Micay (Colombia), 
Werner Hopp observed the species coming to the light about two hours earlier than punctigera, at 10 p. m. 
Costa Rica, Panama, Colombia, Ecuador. 
T. semirufa Drc. (160 g) resembles punctigera in the habitus. Forewing brown excepting the white 
costal stripe which is narrowly red outside. The transverse row of black spots through the forewing is absent 
or rarely rudimentarily represented by single dots. Peru, Bolivia. 
T. zernyi Hopp (160 g) is quite isolated among the Trosia. The neuration is also different, since the 
2nd and 3rd medial veins (veins 4 and 5) of the forewing and the 1st cubital vein and 3rd medial vein (3 and 4) 
are on a short stalk instead of being separated. Judging from the shape of the 10th abdominal segment, however, 
the species belongs to Trosia. The 9th abdominal segment of the $ shows very long, strongly curved sacculi; 
the penis-case rests on a high support of the tegumen and is far aw'ay from the base of the sacculi, but near 
the harps. Completely dark greyish-brown with a darkened costa of the forewdng and somewhat lighter fringe. 
Expanse of 15 mm. The short black antennae are broadly pinnate. Amazons: Taperinha near Manaos. 
13. Genus: Macara Dogn. 
The nomenclature of the genus is sti'angely confused. Macara owes its name to an individual anomaly 
of the veins sometimes occurring in these species in the way described and otherwise. The generic type argentea 
Dgn. however, proves to be synonymous to argentea Drc. (Carama) which Dyar placed first to Norape, later 
to Trosia. Besides there was yet a genus Sulychra Butl. But the attempt of uniting the M acara-species with 
this genus w r as frustrated by the generic type argentea Butl. being an artefact, i. e. the $ of Norape argyrorrhoea 
Him. (= Carama pura Butl.) with male antennae glued on. Moreover, pasaleuca Maass. was placed to the 
hymantriidae (Leucoma) by the author, to Mesoscia Him. by Dyar, and its synonyms verditincta and nivei- 
tincta Dogn. to Mesoscia. Furthermore, purens Schs. and nigripes Dyar were described as Trosia, dyari Dogn. 
as Mahnella, terena Dogn. as Mesoscia. 
In Macara, the appendage of the 10th male ventral segment is azygous and represents a roundish, 
massive, less chitinized “ventrum'’ bearing dorsally near the end a. strongly chitinized small pointed hook or 
clasp-thorn; the latter extends distally as far as the “ventrum”. Nearly all the species have light, relatively 
long antennae, white wings with a black costa of the forewing; the yellow colouring of the head and abdomen 
occurring in many white species of Norape is absent here. 
M. argentea Drc. (argentea Dogn.) (160 h) is recognizable by the broad silvery transverse stripes on 
the forewing, similar to the Lvmantriid genus Caviria. Costa of forewing white, legs black, partly covered with 
white hair. Costa Rica, Panama, Colombia, British Guiana, Ecuador, Peru. 
M. nigripes Dyar has likewise a white costa on the forewdng which is less glossy, as it only shows a single
